I mean, at this point I think everyone should just accept that at the very least their name, age, address(es), email(s), phone number(s) and screen name(s) have been fully leaked if you have ever had any kind of online presence. Not saying that's right or good, but at this point it's just a fact.

So if that's the case, I think we should move beyond really even trying to think of this info as private or a marker of identity, and we need to move everyone to more secure forms of identity verification.

As has been pointed out on HN before, "identity theft" is a made-up concept to make it seem as if you had something stolen from you, when the real problem is banks and other service providers do an absolute shit job of identity verification. They're the ones at fault, and they try to shift the onus onto you to fix things when they screw up.

Indeed, a social security number is pretty much the only additional piece of data to the stuff above that one would need to open up a bank account in someone else's name, and those have been leaked plenty of times too.

The government needs to make harsher penalties for banks and others that can ruin your credit, etc. because they accept all this leaked info as "proof" of identity.

Re:533M Facebook users' phone numbers and personal data have... by AnthonyMouse on Sunday April 04, 2021 @02:13AM (#26687308)
The problem is completely the opposite. The flaw is the existence of social security numbers. Prohibit them from being used for anything but social security.

Then there is no "your social security number" or "your identity" for someone to open a bank account against. You open a bank account and they give you a bank card and you set an address and phone number. The day you open it, they shouldn't need to know who you are, because it's a new account with $0 in it. After that, the owner of the account is the person with that bank card who can be reached at the address and phone number given when the account was created.

Get rid of centralized identity and there is no centralized identity to steal.

Money-laundering rules make it illegal for banks not to know who the customer is. Also various anti-bribery and sanctions rules.
Re:533M Facebook users' phone numbers and personal data have... by AnthonyMouse on Sunday April 04, 2021 @08:57PM (#26694304)
None of those rules are worth the cost. Identity theft, created by the concept of centralized identity, costs billions of dollars. Investigations of those other crimes are still possible without government-mandated privacy invasions by banks, and the privacy invasions are a huge cost in themselves.
Re:533M Facebook users' phone numbers and personal data have... by bboreham on Wednesday April 07, 2021 @03:25AM (#26721440)
Maybe.

How would you feel if an investigation stalled when a bank said “we have no idea who these people are, or where the money went”?

KYC laws and governments desire to have silent complete financial surveillance stops banks from acting that way too.

Why not FIX how an SSN can be used? It was not created for this purpose but that doesn't mean how we use it can't be fixed.

Any time someone attempts to use your SSN to identify themselves as you, you should be notified and your authorization should be required for that use to be allowed.

And the higher the value of the authorization, the more care should be required.

Companies are able to do this already with 2 factor authentication. And I think we SORT of have that for change of address, as the Post Office both requires ID and notifies you by mail. Maybe that's really just one factor.

Allow people to require as many additional factors as they want. Confirming my identity in 6 ways when I decide to sell my house sounds good. 4 ways when I buy a car. One or none is fine when I make a $10 purchase. Let me decide.

And let them CHOOSE what organization manages authentication. A private company might do the job a lot more effectively than the Post Office.

Add human methods too. A call from a sibling or child might be one people could set up. Require validation by a notary public.

> Any time someone attempts to use your SSN to identify themselves as you, you should be notified and your authorization should be required for that use to be allowed.

So now the government needs a way of contacting you. Suppose they have your address and phone number on file.

Then you lose your way a while and become homeless for two years. You can't afford a phone and no longer have the same address, and have lost your ID or it expired. You finally start to turn it around and go to open a bank account. The government contacts you how? How do they know it's you?

The answer is that it's a new account and you're not trying to prove anything about whether you're the same person who lived at the old address, so you shouldn't have to.

And once you have a bank account or a mortgage or such, you and the bank can arrange for any form(s) of authentication you like. It shouldn't have anything to do with the government, and it definitely shouldn't have anything to do with how you authenticate yourself to your job or your wireless carrier.

If a new account can never used to establish your identity for other purposes, there's no problem opening such an account without government identifying you.
Re:533M Facebook users' phone numbers and personal data have... by jand on Sunday April 04, 2021 @02:43AM (#26687415)
I stand by your SSN only for social security point.

But the rest sounds plain wrong to me.

Your phone might get stolen, your name might change due to marriage, your address might change because you moved/got evicted. What now?

Re:533M Facebook users' phone numbers and personal data have... by AnthonyMouse on Sunday April 04, 2021 @03:00AM (#26687472)
Your phone gets stolen so you use your bank card and password to set a new phone number on your account. Your bank card gets stolen so you use your phone and password to get a new bank card.

If someone steals your phone and password and bank card and ability to receive mail at your home address all at once then you're pretty screwed, but you're pretty screwed then regardless, right? That's the level of screwed where somebody else can also get a government ID in your name.

Re:533M Facebook users' phone numbers and personal data have... by laurent92 on Sunday April 04, 2021 @07:12AM (#26688494)
For sufficient amounts or suspicious operations, banks should be in charge of authentification, ie showing up in-person for bank transfers such as a car, showing up and supplying fingerprints if the bank transfer buys a house...

And in fact, for poor people, anything that might engage their entire savings might also benefit from a more advanced identity verification.

For example my stock exchange account just takes a password. It’s a scandal.

Re:533M Facebook users' phone numbers and personal data have... by jand on Sunday April 04, 2021 @03:14AM (#26687522)
Well, you did not mention a password before. With a password, you introduce a new 'security feature' which changes your argument in a non-trivial way.

This might work better than your proposal before.

Re:533M Facebook users' phone numbers and personal data have... by dheera on Sunday April 04, 2021 @02:28PM (#26691712)
I use a slightly different address with every business I give my address to.

For example

123 Main St. Apt 45-WXYZ

Where "WXYZ" is different for each business, to pollute any data mining algorithms trying to collate my address across sites. In some cases when they use address resolving functions, it also helps to spell out your address e.g.

123 Main St. Apt FOURTY_FIVE WXYZ

SSN is used as taxpayer ID, that is why it is needed.

Now, there is absolutely no reason it could not be OTP'd (or uniquely derived for each account).

Re:533M Facebook users' phone numbers and personal data have... by ubertoop on Saturday April 03, 2021 @05:07PM (#26684747)
The scary thing is how much ones phone number (a somewhat ephemeral thing) is actually bound to your IDENTITY.

Considering your phone number is more and more being used in 2FA ... if you were to ever change your number and someone else got it, this would pose a serious security risk if you failed to change over ALL of your internet accounts 2FA to the new number.

Re:533M Facebook users' phone numbers and personal data have... by ourcat on Saturday April 03, 2021 @06:21PM (#26685267)
I've always thought the most scary thing about this practice is that your (unique) phone number is a powerful "foreign key" which could potentially join data from many other leaked databases, forming an even larger dataset on you.

There are plently of other places we give our phone numbers to, which might not have anywhere near the protections that Facebook say they provide.

Re:533M Facebook users' phone numbers and personal data have... by mopsi on Saturday April 03, 2021 @07:04PM (#26685526)
Absolutely, and e-mail or Paypal account name too. Neither of them are trivial to change. If you try to create a new account for each thing at a generic mail provider such as Gmail, your accounts will be shut down by automatic abuse filters. If you roll your own domain, then, well... the domain becomes the foreign key.
Re:533M Facebook users' phone numbers and personal data have... by Perseids on Sunday April 04, 2021 @06:11AM (#26688190)
The solution to this is unlimited true email aliases as e.g. StartMail [1] and Fastmail [2] provide. I wish this was more common place for email provider. Besides the front up cost of developing / setting up the solution, email aliases have the marginal cost of one small database row per alias. And it would be such a boon for privacy.

Would using a separate service email accounts help mitigate issues? [email protected], then [email protected], [email protected], etc? That way my primary email would stay private and will used only for email, not for identity.

Your private email that you don't use for signing up anywhere is irrelevant except for phishing and spam. Your secondary email address will become the foreign key that is used to correlate the datasets from everywhere you signed up with it. The +tags can just be removed since it is known how they work. Might give you a small protection against attackers who don't know about email address tags.

> more and more being used in 2FA

Lesson: Don't use your phone number for 2FA. Get a bunch of virtual numbers and redirect their SMS to your e-mail.

If U2F or TOTP is an option, use it. And use a physical key for TOTP, not some Google or Microsoft authenticator.

Like really? Don't you have to walk to a bank or show some ID?

I live in the EU and I do operate under the assumption that banks take reasonable measures to ensure an account is linked to a legal identity.

Re:533M Facebook users' phone numbers and personal data have... by the_svd_doctor on Sunday April 04, 2021 @02:01AM (#26687255)
No in the Us you can easily open one online just by answering a few questions and giving your SSN. Sometimes they will ask you to upload an ID. But that could also have been leaked.
Re:533M Facebook users' phone numbers and personal data have... by hn_throwaway_99 on Saturday April 03, 2021 @02:08PM (#26683247)
No. Many online services will let you open a bank account with name, address, phone, DOB and social security number.

It turns out that signing up for a new bank account is something that people commonly do at the same time as they're moving to a new place and change their address and phone number.

Well, I think at this point we can conclude that companies will not be good shepherds of our should-be-private data if we don't incentivize them to. Who'd have guessed?

I appreciate the pragmatic stance you take, and we should definitely move to more robust identification methods.

But making this case for better ID tech should IMHO not be confused with giving facebook and the others a pass. This should never have happened, and the very fact that we have a data trove this big is already a problem. That they don't seem to even attempt to protect that data is another one.

Close that shop up. The fines for this kind of stuff (and the other stunts they've pulled) should make it economically no longer viable to keep it open, really. The first time you fuck up this hard, the fines should hurt. This is not their first time.

Companies effectively run the government, via the 2 party system and the back and forth of high level corporate execs back and forth into gov't. They don't want to rock the boat once that bountiful position is achieved. That said, how to get the government to regulate corporations who regulate the government. Maybe I'm becoming too cynical, but there has to be an externality like the great depression in order for The People to take back the reigns of power (at least in the US).

Wont happen. All the politicians world over have been trained like Pavlovs dogs to chase Likes as a route to power. So its like asking addicts to not just give up their drugs but to take down the cartels.

The time to shutdown Facebook has past. Now we just have to suck it up and endure them and their effects like we do Cancer.

I am not from the US, but is this really all you need to "proof" your identity?

The most common thing I have seen in the EU when companies have a KYC requirement is that during the sign up process you will have a quick video call where you have show your ID card while they verify that your ID is legit.

Yes. I think the scary part is WHAT these identifiers are connected to. EG. your email being linked to a private antifa community, pro-Taiwan communities, adulteration meetups, etc.

Even if this info wouldn't be good enough to sign for official stuff it's still private and unique enough to target you though.
