The technical challenges aside, I’m very disturbed that my device will be reporting me to the authorities.

That’s very different from authorities taking a sneak peek into my stuff.

That’s like the theological concept of always being watched.

It starts with child pornography but the technology is indifferent towards it, it can be anything.

It’s always about the children because we all want to save the children. Soon they will start asking you start saving your country. Depending on your location they will start checking against sins against religion, race, family values, political activities.

I bet you, after the next election in the US your device will be reporting you for spreading far right or deep state lies, depending on who wins.

I’m big Apple fanboy, but I’m not going to carry a snitch in my pocket. That’s “U2 Album in everyone’s iTunes library” blunder level creepy with the only difference that it’s actually truly creepy.

In my case, my iPhone is going to be snitching me to Boris and Erdogan, in your case it could be Macron, Bolsonaro, Biden, Trump etc.

That’s no go for me, you can decide for yourself.

Genuinely curious, why? This scanning was already happening server-side in your iCloud photos, just like Google Photos, etc. Now they are removing it from server-side to client-side (which still require this photo to be hosted in iCloud)

What changed, really?

Re:The Problem with Perceptual Hashes by asimpletune on Sunday August 08, 2021 @08:58AM (#28106362)
The problem for me is my device “informing” on me changes the fundamental nature of my device. Also the opaqueness of the whole system is concerning, along with the potential for false positives. And lastly is the “if this then what’s next?” And that is definitely a road I don’t want to go down on.

For me it’s sad because I have literally always stood by them and they make amazing hardware and software. However at the end of the day I’d rather have the nature of my device be one where it is under my control, than all the wonderful apple tech.

I just don’t know what to use instead.

If I ask you to store my images, and you therefore have access to the images, you can scan them for stuff using your computers. The scope is limited to the images I ask you to store, and your computers are doing what you ask them to.

If you reprogram my computer to scan my images stored on my computer… different thing entirely. I don't have a problem with checking them for child abuse (in fact, I'd give up quite a bit of freedom to stop that), but nothing about this tech makes it specific to child abuse. I don't want my computer ratting me out for stuff that I have the right (or, possibly, the obligation) to be doing, just because the powerful don't want me doing it. At the moment, it doesn't.

This tech makes Apple-controlled computers untrustworthy. It will probably lead to the deaths of political dissidents; these things always do. Is that worth it?

Re:The Problem with Perceptual Hashes by acdha on Saturday August 07, 2021 @03:10PM (#28101037)
So far, this is only for iCloud photos so currently it seems highly similar to what we have now except that it’s on the device and could be done with end to end encryption, unlike the current approach.

For me, the big concern is how it could be expanded. This is a real and valid problem but it’s certainly not hard to imagine a government insisting it needs to be expanded to cover all photos, even for people not using iCloud, and we’d like you to add these signatures from some images we can’t show you. Once the infrastructure is there it’s a lot easier to do that.

Re:The Problem with Perceptual Hashes by wizzwizz4 on Saturday August 07, 2021 @03:31PM (#28101186)
Yes. If Apple takes the “we're not going to” stance, then this could be okay… but they've been doing that less and less, and they only ever really did that in the US / Australia. Apple just isn't trustworthy enough.
Re:The Problem with Perceptual Hashes by acdha on Saturday August 07, 2021 @03:49PM (#28101284)
Also that since the system is opaque by design it’d be really hard to tell if details changes. Technically I understand why that’s the case but it makes the question of trust really hard.

Good! These assholes have been building a moat around all of computing, and now it's almost impossible to avoid the multi-trillion dollar monster.

Think about all the startups that can't deploy software without being taxed most of our margin, the sign in with apple that prevents us from having a real customer relationship, and the horrible support, libraries, constant changes, etc. It's hostile! It's unfair that the DOJ hasn't done anything about it.

A modern startup cannot succeed without Apple's blessing. To do so would be giving up 50% of the American market. When you're struggling to grow and find traction, you can't do that. It's so wildly unfair that they "own" 50+% of computer users.

Think of all the device owners that don't have the money to pay Apple for new devices or upgrades. They can't repair them themselves. Apple's products are meant to go into the trash and be replaced with new models.

We want to sidestep these shenanigans and use our own devices? Load our own cloud software? We can't! Apple, from the moment Jobs decreed, was fully owned property. No alternative browsers, no scripting or runtimes. No computing outside the lines. You're just renting.

This company is so awful.

Please call your representatives and ask them to break up the biggest and most dangerous monopoly in the world.

With you up to here, but this is jumping the shark

> I bet you, after the next election in the US your device will be reporting you for spreading far right or deep state lies, depending on who wins.

The US is becoming less stable, sure [1], but there is still a very strong culture of free speech, particularly political speech. I put the odds that your device will be reporting on that within 4 years as approximately 0. The extent that you see any interference with speech today is corporations choosing not to repeat certain speech to the public. Not them even looking to scan collections of files about it, not them reporting it to the government, and the government certainly wouldn't be interested if they tried.

The odds that it's reporting other crimes than child porn though, say, copyright infringement. That strikes me as not-so-low.

[1] I agree with this so much that it's part of why I just quit a job that would have required me to move to the US.

Re:The Problem with Perceptual Hashes by jacoblambda on Saturday August 07, 2021 @04:48AM (#28096998)
FYI Illiberal values aka non-liberal values (clarifying because the I is hard to read) use the word liberal in the traditional sense.

Liberal values are liberty/freedom, consent of the governed, and equality before the law. All other liberal values build off of these three as a base. This implies that Non-liberal (or illiberal) values are the opposition of liberal values through censorship, gun control, etc like you mentioned.

Liberals in the modern US political sense refers to Neo-liberals. Neo-liberal and liberal are two very different things which is why the term liberal value doesn't necessarily correspond to neo-liberal beliefs.

Additionally, "the left" by and large does not support neo-liberalism. "The left" is violently against the aforementioned censorship, gun control, etc. Reading any socialist or communist literature will make this abundantly clear.

Examples:

- George Orwell on the Right to bear Arms: "The totalitarian states can do great things, but there is one thing they cannot do, they cannot give the factory worker a rifle and tell him to take it home and keep it in his bedroom. That rifle hanging on the wall of the working-class flat or labourer's cottage is the symbol of democracy. It is our job to see it stays there."

- George Orwell on Freedom of Speech: "Threats to freedom of speech, writing and action, though often trivial in isolation, are cumulative in their effect and, unless checked, lead to a general disrespect for the rights of the citizen."

- Karl Marx on the Right to bear Arms: "Under no pretext should arms and ammunition be surrendered; any attempt to disarm the workers must be frustrated, by force if necessary"

- Karl Marx on Freedom of Speech: "The absence of freedom of the press makes all other freedoms illusory. One form of freedom governs another just as one limb of the body does another. Whenever a particular freedom is put in question, freedom in general is put in question"

- Karl Marx on Freedom of Speech: "Censorship has outlived its time; where it still exists, it will be regarded as a hateful constraint which prohibits what is openly said from being written"

- Karl Marx on Freedom of Speech: "You cannot enjoy the advantages of a free press without putting up with its inconveniences. You cannot pluck the rose without its thorns!"

If you want I can dig up more quotes but those are the ones that were easy to fetch and any more risks turning this into even more of a wall of text.

My point being, your issues with "the left" are misdirected and are better focused towards Neo-liberalism and/or Neo-conservatism. "The left" does and has always been one of the primary guardians of liberal ideology. Hell "the left" is where a significant portion of the liberal ideology that the United States is founded on originated from.

Re:The Problem with Perceptual Hashes by goldenkey on Saturday August 07, 2021 @05:59AM (#28097328)
Those are great but the left in its current form pushes for larger and larger government. I believe that large government is incompatible with freedom. A hammer will always find a nail given enough time for bad actors to exploit the search space.

Marxism prescribes the atrophy of the state: https://en.wikipedia.org/wiki/Withering_away_of_the_state

The left as it stands in its current dominant form, is a hypocrisy of incompatibles.

True liberalism as you describe it, doesn't exist in any first world country. It's been bundled into larger and larger government creep which inevitably tramples on individual rights.

Owning a laptop is perhaps a very tiny investment in capital, arguably, but it certainly won't provide enough passive income to replace your job.

If you work for a living without owning the means of production and receiving the fruits of your labour, you are part of the proletariat.

If you own the means of production and receive the full fruits of your labour, you are part of the bourgeoisie.

Self employed programmers are bourgeoisie, employed ones are not. And of those that are part of the bourgeoisie, there are levels and not all of them are bad (even in the scope of socialist theory).

- The petite bourgeoisie are your small self employed shopkeepers, artisans, and tradesmen. These are the people who live by their own means and without exploiting anyone else's labour. Rising the proletariat to this level is the entire point of socialism.

- The moyenne bourgeoisie maintain largely the same lifestyle as the petite bourgeoisie but with strong financial establishment. They are effectively the upper end of the petite bourgeoisie and whether they are considered part of the problem or part of the end goal depends almost entirely on whether they are supported solely by their own labour or if they are unduly exploiting the labour of others. This class may lend money in some capacity however normally if they are doing so, they are doing it collectively.

- The grand bourgeoisie are largely where the problems with the bourgeoisie begin. These people have an established financial status from a few generations of wealth. This class is the one running larger businesses and their wealth is almost entirely derived from the work of others rather than their own.

- The haute bourgeoisie are the "true" bourgeoisie. You can only make it to this class through generations of wealth aggregation (unless you ride an industrial revolution) and once you are here, it is almost impossible to lose your financial status regardless of spending or financial failings. These are the eternally rich and their existence is only sustained by exploiting the labour of others.

Socialist theory considers the petite and moyenne bourgeoisie to be the "end goal" for society. They are nearly entirely sustained by their own labour and may use their excess funds to invest in the community (normally with some expectation of return but not any life sustaining amount). Marx warned that through the natural progression of capitalist society, these classes (primarily the petite but also the moyenne in some capacity) would wither while the wealth collected in the hands of the grand and haute bourgeoisie.

---

Additionally, many socialist and communist nations have strict gun control not because they are socialist or communist, but because they are authoritarian. Gun control is a sign of authoritarianism more than anything else and any nation that falls towards it is going to see the population disarmed.

Free speech doesn't mean the speaker is immune from criticism or social consequences. If I call you a bunch of offensive names here, I'll get downvoted for sure. The comment might be hidden from most. I might get shadowbanned or totally banned, too.

That was true of private spaces long before HN existed. If you're a jerk at a party, you might get thrown out. I'm sure that's been true as long as there have been parties.

Canning Parler is Apple choosing not to advertise and send you an app they don't like, i.e. it's Apple exercising it's own right to free speech. Agree or disagree with it, it's categorically different from Apple spying on what the files you have are saying (not even to or via Apple) and reporting it to the government.
Re:The Problem with Perceptual Hashes by wyager on Friday August 06, 2021 @11:40PM (#28095478)
Apple also disallows you from installing things without going through them, so “choosing not to advertise and send” has a lot more significance than your wording implies.

It’s not like they have a curated App Store for apps they like; there’s literally no other way to add software to the device.

Re:The Problem with Perceptual Hashes by gpm on Saturday August 07, 2021 @09:48AM (#28098559)
Right, but the fallout that prevents you from installing it is an incidental consequence of Apple choosing not to promote it and Apple choosing to use it's monopoly on app distribution as an income channel.

Speech not happening because Apple didn't go out of it's way for it to create a route for it to happen without Apple being involved, isn't really that shocking or similar to Apple scanning private files. (Apple being allowed to prevent you from installing what you want on your phone is shocking from an anti-trust perspective, but not from a speech perspective).

Both sides of the political spectrum think the other side is stupid, and evil. The gap between the two sides is getting bigger. Politicians and people (especially on the right, but to some extent on the left) are increasingly willing to cheat to remain in power.

If you want some concrete examples:

- Trump's attempted coup, the range of support it received, the lack of condemnation it received.

- Law's allowing things like running over protestors

- Law's with the transparent goal of suppressing voters

- Widespread support (not unjustified IMO) for stacking the supreme court

- Police refusing to enforce certain laws as a political stance (not because they legitimately think they're unlawful, just that they don't like them)

- (Justified) lack of trust in the police quickly trending higher

- (Justified?) lack of trust in the military to responsibly use tools you give it, and support for a functional military

- (Justified?) lack of faith in the border guards and the ability to pass reasonable immigration laws, to the point where many people are instead advocating for just not controlling the southern border.

Generally these (and more) all speak towards the institutions that make the US a functional country failing. The institutions that make the rules for the country are losing credibility, the forces that enforce the rules are losing credibility. Neither of those are things that a country can survive forever.

Re:The Problem with Perceptual Hashes by l33t2328 on Saturday August 07, 2021 @03:20PM (#28101106)
Calling what Trump did an attempted coup is hyperbole beyond belief.

The support for packing the supreme court is mostly at the fringes of the party, and there’s always been some support.

There are almost no laws with any kind of support that have transparent goals of suppressing voters. Election security laws are clearly necessary after the doubt the democrats had it was secure in 2016, and the doubts the republicans had in 2020.

Laws absolving drivers of hitting protesters don’t exist. Laws absolving drivers of driving through violent rioters do, and such laws are necessary. I saw a a riot with my own eyes where a half dozen cars were flipped and destroyed, and anyone trying to drive through the intersection had people jumping on their car and smashing the windows. These laws are good.

I would really like people to start answering this: what exactly do you think has changed? e.g,

>That’s very different from authorities taking a sneak peek into my stuff.

To be very blunt:

- The opt out of this is to not use iCloud Photos.

- If you _currently_ use iCloud Photos, your photos are _already_ hash compared.

- Thus the existing opt out is to... not use iCloud Photos.

The exact same outcome can happen regardless of whether it's done on or off device. iCloud has _always_ been a known vector for authorities to peek.

>I’m big Apple fanboy, but I’m not going to carry a snitch in my pocket.

If you use iCloud, you arguably already do.

Re:The Problem with Perceptual Hashes by Renaud on Friday August 06, 2021 @09:59PM (#28094995)
What has changed is the inclusion of spyware technology on the device that can be weaponised to basically report on anything.

Today it's only geared toward iCloud and CSAM. How many lines of codes do you think it will take before it scans all your local pictures?

How hard do you think it will be for an authoritarian regime like China, that Apple bends over backwards to please, to start including other hashes that are not CSAM?

iCloud is opt-out. They can scan server-side like everyone does. Your device is your device, and it now contains, deeply embedded into it, the ability to perform actions that are not under your control and can silently report you directly to the authorities.

If you don't see a deep change there, I don't know what to say.

I live in a country that is getting more authoritarian by the day, where people are sent to prison (some for life) for criticizing the government, sometime just for chanting or printing a slogan.

This is the kind of crap that makes me extremely angry at Apple. Under the guise of something no-one can genuinely be against (think of the children!), they have now included a pretty generic snitch into your phone and made everyone accept it.

Re:The Problem with Perceptual Hashes by Klonoar on Saturday August 07, 2021 @02:09AM (#28096170)
>What has changed is the inclusion of spyware technology on the device that can be weaponised to basically report on anything.

- You are running a closed source proprietary OS that you cannot verify is not already doing anything.

- This could theoretically already be weaponized (with the existing server-side implementation) by getting someone to download a file to a folder that iCloud automatically syncs from.

>iCloud is opt-out.

Yes, and that's how you opt out of this scanning. It's the same opt-out as before.

>Under the guise of something no-one can genuinely be against (think of the children!) they have now included a pretty generic snitch into your phone and made everyone accept it.

I dunno what to tell you. I think the system as designed is actually pretty smart[1] and more transparent than before.

If you used iCloud before, and you're putting photos up that'd be caught in a hash comparison, you've already got a snitch. Same with any other cloud storage, short of hosting your own.

We gotta stop with the China bogeyman every time a privacy issue comes up. This is a feature designed by an American company for American government surveillance purposes. China is perfectly capable of doing the same surveillance or worse on its own citizens, with or without Apple. China has nothing to do with why American tech is progressively implementing more authoritarian features in a supposedly democratic country.
Re:The Problem with Perceptual Hashes by dannyw on Friday August 06, 2021 @11:42PM (#28095490)
China is just an example. In Australia, the law allows our executive department to order tech companies to build backdoors for the investigation of any crime punishable by more than 2 years imprisonment.

We actually had the anti terror department arrest a popular, left-leaning YouTube influencer for harassment while physically assaulting his mum (all on video).

That's something that is literally unprecedented in Hong Kong just 3 years ago.

Ok. How about the Saudi Arabian bogeymen then? Who took Jamal Kashoggi apart with bonesaws as he screamed? Or the Israeli bogeymen who exploited his phone for them? Or the Turkish bogeymen who also a customers of that Israeli phone exploitation company? (Or Facebook who wanted to buy those tools but got turned down, because Facebook is “too far” even for NSO who happily take Saudi and Turkish money?)

There are without doubt enough privacy bogeymen to go around, trying to derail a valid argument over its use of the Chinese as the placeholder bogeyman detracts from the discussion pointlessly.

Re:The Problem with Perceptual Hashes by wonnage on Saturday August 07, 2021 @04:26AM (#28096908)
The point is that all these bogeymen distract from the actual issue, because they make government surveillance sound like something that only happens in other places... We need to wake up and realize it's happening right here at home and has been for decades
Re:The Problem with Perceptual Hashes by Renaud on Saturday August 07, 2021 @01:24AM (#28095964)
No-one was suggesting that China was behind this move.

We're talking about China taking advantage of this integrated technology to increase control over its population through backdoors like these.

China already imposes that all data from Chinese users be located in China and readily accessible and mined by the authorities[1].

Apple is willing to bow to these regimes because it has substantial supply-chain interests there and it sells hundred of millions of devices. A boon to both Apple and the local government.

I think it's irresponsible to avoid thinking about how bad actors might use a technology you've developed.

And is it really unfathomable that the US government could use this sort of thing for evil? I mean, wind back the clock to something like the Red Scare. If they had iPhones back then, they totally would have pressured Apple to add hashes for communist imagery, and use that to persecute people (or worse).

That's neither here, nor there.

I do not believe that iCloud CSAM server side matching ever required a warrant, and I'm not sure where you've gotten this idea. It quite literally is (a) peak automatically in everybody.

Regarding (b), with this way - thanks to them publishing details on it - there's more transparency than if it was done server side.

As noted elsewhere in this very thread, this can happen whether client or server side. It's not unique in any way, shape or form to what Apple is doing here.

The same checking when you synced things to iCloud. As has been repeated over and over again, this check happens for iCloud Photos. It's not running arbitrarily.

Your photos were compared before and they're being compared now... if you're using iCloud Photos.

They weren't always compared, they started being compared a few years ago, and they moved to comparing them with a new scheme now.

Both are bad, and not the responsibility of a company selling phones - and also a bad precedent (now it's "think of the children", tomorrow "think of the country", then "think of those with wrong ideas", then "think how much money insurance companies can save" and what have you).

As for your suggestions to just "stop using iCloud Photos", how about we get to enjoy the features we bought our devices for, without stuff we didn't ask for and don't want?

Apple is not just a hardware company and there is no obligation for them to host offending contents on their servers - just as Dropbox, Google, and so on would maintain with theirs.

The post office scans your mail through various machines in transit. We accept that when we put the mail in the mailbox.

What if the post office announced they were installing a man with a scanning machine in your home who would scan your letters before they left your house?

It's the same outcome. The same process. Just inside your house instead of out in the mail system. They're exactly the same, except somehow it's not.

Re:The Problem with Perceptual Hashes by Klonoar on Friday August 06, 2021 @09:20PM (#28094796)
This example changes with regards to emotional weight if you remove "a man" and leave it at just "a scanning machine". There is no human scanning your photos on an iPhone, so let's compares apples to apples here.

If that scanning machine didn't reveal the contents of my mail, and then ensured that it wasn't able to be given out in-transit? Yeah, I'd potentially be fine with it - but I'll leave this answer as a hypothetical since it's all theory anyway.

The point here is that you're choosing to use the mail system and you're thus choosing to play by those rules. Given that these checks happen for iCloud you're effectively making the same agreement.

Re:The Problem with Perceptual Hashes by dannyw on Friday August 06, 2021 @11:45PM (#28095500)
There actually is a man involved: enough similarities and a human will review the photos. Every algorithm, especially perceptual hashing, will have false positives, and at Apple's scale, some people's private and intimate photos will be false positives and be exposed to a man looking at it.

I think the point of the OP is that it was already the case before when you were using iCloud photos. The scan was server side.
Re:The Problem with Perceptual Hashes by stetrain on Saturday August 07, 2021 @12:30AM (#28095693)
But the barrier between “only happens for iCloud” and “happens for all photos on device” has been reduced to a very small barrier. Before it was the photos actually being sent to a separate server by my choice, now it’s Apple saying their on-device tool only runs given criteria X.

And on a second note I think people are allowed to be freshly concerned at the idea of Apple scanning photo libraries given a government-provided hash list, even if it was already happening before now.

Re:The Problem with Perceptual Hashes by Klonoar on Saturday August 07, 2021 @01:50AM (#28096077)
To be clear, I have no qualms about people being concerned. You can find my comments elsewhere on this site that I think people should scrutinize this entire thing.

Agreed. I still think there is a distinction, even if only in principle and mostly psychological, between what a company does with my files on their server, and what they do with my files on my device.

Even if the outcome is theoretically the same, the means are different and it feels different.

That is a totally bogus comparison.

The post office 100% does NOT can the content of every piece mail they handle.

Not even close to the same scenario as Apple/governments being able to continually and silently check your phone/photo library for images on their watch list.

Re:The Problem with Perceptual Hashes by stetrain on Saturday August 07, 2021 @01:23AM (#28095963)
I’m pretty sure lots of mail gets x-rayed, perhaps even more looking for malicious packages or substances.

I agree that data content scanning is more invasive than physical scanning. It was an intentionally simplistic example not meant to defend Apple.

It's not the same because before the hashing was done in the cloud, but now the model is accessible locally, you just need to take pictures. This means it's easier to hack.

If someone discovers a way to reliably generate adversarial images they can send such images to someone else to iSWAT them.

Re:The Problem with Perceptual Hashes by Klonoar on Saturday August 07, 2021 @01:58AM (#28096114)
If your definition of "hack" is "get bob to accept bad file", no, this model is not easier - it's just different.

You could literally piggyback on the directories that Macs use to sync to iCloud Drive, get an image in there, and then it gets scanned by iCloud. This is not some new theoretical attack - and in fact, this would be the "hack" for the new one as well since it requires iCloud sync to trigger anyway.

Re:The Problem with Perceptual Hashes by visarga on Sunday August 08, 2021 @05:13AM (#28105270)
I was referring to a "white box" adversarial attack, meaning you can try variations of the input to see how the outcome changes, and then construct an input that will fool the system. That's only possible if you have access to the perceptual hashing model, which you do now since it runs locally.

Of course generating an adversarial image is not the final step, the hacker still need to place it in the victim's account somehow, but it's easier now because the image looks legit.

Re:The Problem with Perceptual Hashes by foerbert on Friday August 06, 2021 @11:24PM (#28095411)
I think one of the major factors that changes how people perceive this is that it's happen on their own device. If you upload a thing to a server and the server does something... I mean sure. You gave a thing to somebody else, and they did something with it. That's a very understandable and largely accepted situation.

This is different. This is your own device doing that thing, out of your control. Alright sure, it's doing the same thing as the other server did and under the same circumstances* so maybe functionally nothing has changed. But the philosophical difference is quite huge between somebody else's server watching over what you upload and your own device doing it.

I'm struggling to come up with a good analogy. The closest I can really think of is the difference between a reasonably trusted work friend and your own family member reporting you to the authorities for suspicious behavior in your workplace and home respectively. The end result is the same, but I suspect few people would feel the same about those situations.

* There is no inherent limitation for your own device to only be able to check photos you upload to iCloud. There is however such a limitation for the iCloud servers. A very reasonably and potentially functional difference is the ability for this surveillance to be easily expanded beyond iCloud uploads in the future.

Re:The Problem with Perceptual Hashes by matheusmoreira on Friday August 06, 2021 @11:56PM (#28095553)

Now what's going to happen instead is the computer will report me to its real masters: corporations, governments. How is this acceptable in any way?

It makes even less sense, given that they are currently doing this with your iCloud photos. Now they have this tool that can match to a database of photos, how do we know they wouldn't use this to identify non-sexual photos? Maybe Tim Cook wouldn't, what about the next CEO? And the one after that?
Re:The Problem with Perceptual Hashes by tialaramex on Friday August 06, 2021 @10:55PM (#28095285)
What makes you think that Apple has a database of actual child sex abuse images? Does that feel like a thing you'd be OK with? "Oh, this is Jim, he's the guy who keeps our archive of sex abuse photographs here at One Infinite Loop" ? If you feel OK with that at Apple, how about at Facebook? Tencent? What about the new ten-person SV start-up would-be Facebook killer whose main founder had a felony conviction in 1996 for violating the Mann Act. Still comfortable?

Far more likely Apple takes a bunch of hashes from a third party in the law enforcement side of things (ie cops) and trust that the third party is definitely giving them hashes to protect against the Very Bad Thing that Apple's customers are worried about.

Whereupon what you're actually trusting isn't Tim Cook, it's a cop. I'm told there are good cops. Maybe all this is done exclusively by good cops. For now.

Now, I don't know about the USA, but around here we don't let cops just snoop about in our stuff, on the off-chance that by doing so they might find kiddie porn. So it should be striking that apparently Apple expects you to be OK with that.

Re:The Problem with Perceptual Hashes by megous on Saturday August 07, 2021 @04:28AM (#28096912)
Any of these large services allowing user uploaded content can build such a database in a heartbeat. And with a list of known hashes it can even be automated.
Re:The Problem with Perceptual Hashes by Klonoar on Friday August 06, 2021 @08:51PM (#28094592)
The questions re: what the CEO would sign off on here don't really matter, as the question could apply whether it's server side or client side.

It _does_ make sense client side if you view it being done server side as a blocker for E2EE on iCloud. There is absolutely no world where Apple could implement that without keeping the ability to say "yes, we're blocking child porn".

Wasn’t yesterday’s version of this sorry about how Apple is implementing this as a client side service on iPhones?

https://news.ycombinator.com/item?id=28068741

I don’t know if the implication there is “don’t use the stock Apple camera app and photo albums”, or “don’t store any images on yours Phone any more” if they are scanning files from other apps for perceptual hash matches as well…

Re:The Problem with Perceptual Hashes by Klonoar on Saturday August 07, 2021 @01:54AM (#28096100)
...yes, and the client-side check is only run before syncing to iCloud Photos, which is basically just shifting the hash check from before upload (client side) to after upload (server side).
Re:The Problem with Perceptual Hashes by aix1 on Saturday August 07, 2021 @04:08AM (#28096792)
Thanks for this clarification. This, I think, is an important aspect that seems to often get overlooked.

Apple's explanation:

<quote> Before an image is stored in iCloud Photos, an on-device matching process is performed for that image against the known CSAM hashes. This matching process is powered by a cryptographic technology called private set intersection, which determines if there is a match without revealing the result. The device creates a cryptographic safety voucher that encodes the match result along with additional encrypted data about the image. This voucher is uploaded to iCloud Photos along with the image.

Using another technology called threshold secret sharing, the system ensures the contents of the safety vouchers cannot be interpreted by Apple unless the iCloud Photos account crosses a threshold of known CSAM content. The threshold is set to provide an extremely high level of accuracy and ensures less than a one in one trillion chance per year of incorrectly flagging a given account. </quote>

Re:The Problem with Perceptual Hashes by bigiain on Monday August 09, 2021 @12:12AM (#28112686)
I'm actually super impressed at the lengths they went to make this as private as they did.

With the proviso that you have to trust the code they push onto your device actually does what they claim in the paper.

But it does, on the face of it, prevent the "cops adding the latest cop on black person murder viral image to the CSAM content hashes and easily seeing who has it on their device and when it showed up there" concern. They are at least going to need to add enough _other_ hashes to the list to get everybody with their target image over the threshold, then get it past whatever Apple has in place for their manual review and "visual derivatives". And surely that sort of abuse of the system would set off alarms instantly at Apple when a big list of hashes of images that are common enough to all push BLM activists and sympathisers over the CASM count threshold.

(I also wonder what those "visual derivatives" they get are, and how well they are going to work to filter out false positives, and how Apple are going to take care of whoever ends up doing that review work. While I have a fairly positive impression of the care and effort Apple put into ensuring my privacy, I have a somewhat less positive impression of how they treat outsourced or low-skill workers. I won't be _too_ surprised to hear the same sort of horror stories about both the work, and the management overseeing the workers that do this sort of job at Facebook... I can't imagine a worse job description than "review images to check if they are real child sexual abuse images", and doing that for minimum wage and no benefits with supervisors threatening to fire you if you take toilet breaks or miss your 150 images an hour targets - is sadly something I totally expect to read about in a year or two's time.)

"The third-party doctrine is a United States legal doctrine that holds that people who voluntarily give information to third parties—such as banks, phone companies, internet service providers, and e-mail servers—have "no reasonable expectation of privacy." A lack of privacy protection allows the United States government to obtain information from third parties without a legal warrant and without otherwise complying with the Fourth Amendment prohibition against search and seizure without probable cause and a judicial search warrant." --wiki

Okay, but the users of said 3rd party are doing it under the assumption that it is encrypted on the 3rd party's system in a way that they cannot gain access to it. The unencrypted data is not what the user is giving to iCloud. So technically, the data this scan is providing to the authorities is not the same data that the user is giving to the 3rd parties.

Definitely some wiggle room on both sides for some well versed lawyers to chew up some billing hours.

Public and political pressure is definitely an issue - but it's still soft-pressure so applying more pressure in the other direction will be compelling to Apple.

Re:The Problem with Perceptual Hashes by mrtksn on Friday August 06, 2021 @07:43PM (#28094117)
Apple was supposed to E2E encrypt everything. Then reports surfaced that FBI complained and they stopped.

The are speculations about this being Apple’s solution to government demands so that they can continue migrating to E2E.

They are trying a solution where the device reports you to the authorities so that Apple gets out of the business of knowing your data.

Re:The Problem with Perceptual Hashes by mrtksn on Saturday August 07, 2021 @07:14AM (#28097666)
Just to clarify, this "on device content control" defies all the benefits of the E2E encryption because it is "at the end". It will enable Apple to implement E2E and give the authorities a channel to program the devices to report users in possession of content deemed unacceptable by the authorities.

In fairness, in the "old way" it was impossible for two random people to communicate in real-time between continents without the ability of authorities to observe/break it.

Privacy and security is quite important, but let's not lose track of the fact that there are many tools authorities have lost in the past few decades. In WWII major powers weren't able to have the same security of military communications as an idiot can today. And that's relative to codebreaking technology.

Won't help, the detection of on your phone now. I wonder if one can have a local VPN with a profile installed which could MITM iCloud upload process and take those matching envelops out.

But in the end of the day the only robust way to communicate privately is good old Linux with good old mutt with good old PGP

you have to realize though that the panopticon is limited only by the ability of "authority" to sift through it for whatever it is it is looking for.

as this article points out, the positive matches will still need an observe to confirm what it is and is not.

lastly, the very reason you have this device exposes you to the reality of either accepting a government that regulates these corporate overreaches or accepting private ownership thats profit motive is deeply personal.

you basically have to reverse society or learn to be a hermit, or more realistically, buy into a improved democratic construct that opts into transparent regulation.

but it sounds more like you want to live in a split brained world where your paranoia and antigovernment stance invites dark corporste policies to sell you out anyway
