Search the World's Smartphone Photos

mikejuk writes "Researchers have devised and tested a system called Theia that can perform an efficient parallel search of mobile phones to track down a target photo. It could be used to perform a realtime search for a missing child accidently caught in a photo you have just taken or the location of a criminal or political activist. You might think that the security and privacy aspects were so terrible that you just wouldn't install the app. However exceptional photos of a sporting or news incidents are worth money and the profit motive might be enough for you to install it."

I read a book once

I read a book once. It was about a society where spying eyes could detect the acts of political activists. It wasnt a pretty book.

Those images of publicly viewable should be subject to automated searching for criminal evidence. If a billion cops could legitimately stand there watching and writing down notes, it's legit to replace them with sensors, networks, and AI.

There are two assumptions here. Firstly that anything you do in public is fair game, and secondly any activity that we accept when it's done the old-fashioned (and tedious) way is equally legitimate when it's done in a high-speed, automated manner.

Some- myself included- disagree with both these general premises. A hundred years ago, if you did something in public, people could see you and talk about you, but there wasn't the chance of some video of you doing something stupid hanging around forever, or someone in power easily being able to see you doing that.

In short, the implications of doing something in public have changed a lot, even in the past 30 years, and the social rules surrounding that date back to before this time. Even then, you generally couldn't have got away with (e.g.) stalking someone, even if they were doing it "in public", so it's not like there was ever *no* level of "privacy" towards people in public spaces.

Secondly, doing some surveillance activity in the old-fashioned, tedious manner by definition limited it to people the police had a reason to focus on. Doing it in an automated manner makes it possible to gather information on and track people in general, regardless of whether or not there is a fair reason to do this, and makes a police state or "surveillance society" possible in a way that doing it by hand doesn't.

In short, this is a case where a quantitative change in how much something can be done makes a *qualitative* change to its effects, i.e. it is *not* simply a case of letting the police do their old job faster- it fundamentally changes it. And this is why (IMHO) doing it the new way should *not* get a free pass because it's always been like that.... because it hasn't.
