> We identify a number of critical issues that need to be addressed in this space... First, individuals should be provided the opportunity to opt out of SENS services – in other words, to avoid being monitored and tracked by the Wi-Fi devices around them.

Bad news, the paper proposes remote human identification by every Wi-Fi device.

> This would require the widespread introduction of reliable SENS algorithm for human or animal identification.

Would opt-in be legally easier than requiring human body scan registration for opt-out of Wi-Fi remote sensing?

In order to not be tracked you must consent to be tracked so we know you don't want to be tracked.

This should not be done or allowed. Period. It's a huge invasion of privacy.

Or, better yet, make it totally opt in.

And if $CAFE tracks you regardless of you not ticking the box or connecting to the network, how do I detect that as a regular customer?

Unfortunately these will be everywhere, far beyond any existing camera surveillance network.

The cost of those devices should fall with 802.11bf Wi-Fi.

> the vans deliver a radiation dose 40 percent larger than delivered by a backscatter airport scanner; bystanders present when the van is in use are exposed to the radiation that the van emits… there may be significant health risks associated with the use of backscatter x-ray devices as these machines use ionizing radiation, a type of radiation long known to mutate DNA and cause cancer.

Could this radiation meter detect the presence of such a van?

I've been looking into this for a while, should be mature enough in a year or so. there are already dozens of companies in this space

e.g. lockpicks are regulated, how about wallpicks-via-WiFi?

> In Japan if you are found with lock picks you will be subject to a fine of 500,000 yen and a year in prison. In Poland, it is illegal to possess any picks without being able to show that your profession requires it ... In Hungary ownership of lock picks is completely illegal. The only people in Hungary that are allowed to have these tools are the military, and as a result lock picks are classified as military equipment. For travel within the United States or even traveling to the US, you should consult the lock pick laws in the state you are visiting.
