Lifestyle business idea: wear somebody's printed-out paper face at a place it can be recorded (public photos to Flickr feed, etc) as a service.

A customer who uses services of this kind can "prove" they're anywhere in the world at a given time.

Useful for celebrity misdirection, criminal alibis and the like.

I wonder how effective systems like https://cvdazzle.com/ are against this. Will we all be putting on masks or face-paint in the future when we go outside?

Whenever I see some of these 'countermeasures' I usually run them through some high end commercial face recognition algorithms I have access to. In many of the cases the countermeasures are completely ineffective. They may fool some things like opencv DIY algorithms, but not the expensive stuff :). For those the most effective strategy is to just tilt your head to the left or right a lot, though that will possibly gi…

> just tilt your head to the left or right a lot

That seems like an trivially simple thing to defeat from a code perspective.

> Even today it's no problem to analyze the Facebook picture of some random person and calculate a chance of that person being an alcoholic in X years based on the number of party pictures they share. The problem is not that this calculation exists, but that people so easily misinterpret it. It doesn't mean "Person with these photos has a 65% chance of being an alcoholic in 5 years", what it REALLY means is "65% of t…

The calculation is useful from a marketing perspective. If I decide to advertise alcoholism treatments to these people in five years' time, I'll have a lot more success then if I'd just picked people at random to advertise to.

..and in the meantime, you can advertise alcohol to these people. It's a win-win!

> (the consumer's fault). I doubt that. No one prevents someone tagging me on Facebook even if I don't have a Facebook account. Now Facebook knows my name and the corresponding face without me ever using Facebook.

Well you can't do that. You can only tag someone with an account.

You can tag anyone on Facebook even if they don't have an account. When you start typing their name a drop-down box of suggestions appears. Hit the escape key and you can continue typing their name and tag them.

Anyone with your photo can associate it with your name on Facebook even if you don't use it.

This is an unbelievably ridiculous argument. Just because the government has something doesn't mean everyone can or should.

You do realize the irony in your argument, considering its the Russian government which has probably the worst track record in recent times when it comes to a corrupt government abusing its power. What you are essentially saying is that [1] this is bad but a government having a similar tool is fine. [1] https://en.wikipedia.org/wiki/Human_flesh_search_engine

I never said the government having it is fine. But the fact that it does doesn't mean you shouldn't be concerned about corporations and private people having it. And I certainly did not mention the Russian government.

With all the data being collected, has anyone been able to use it to defend themselves based on location and time recorded? I tend to think that if we're recording all of it, it ought to be immutable and sealed so that one can at least use it as evidence, but the cynic in me thinks this isn't something the governing powers have any interest in allowing.

I think if (more likely, when) we get to the point where people can have an alibi in this way, it will quickly turn sour. When you're accused of a crime and you can't be located during that time, it'll be used to make you look guilty—not just neutral.

My primary concern is who records and stores the data and how trustworthy it is. If a judge reasonably just believes a printout from law_inquiry@facebook.com, how am I able to prove the data is wrong? Therefore, we need standards and tamper proof records just as they are created on a device or even on servers. It's funny that so much of our ability to live a somewhat free life without getting locked up depends on cryptography.

> The algorithm comes from Moscow-based NTechLab, which recently boasted it bested Google’s recognition software at MegaFace, a technical challenge hosted by the University of Washington. It's a bit baffling to me why University of Washington was trying to accelerate this capability. I'm all for pure academia, but this is just fingerprinting someone's face. The real tech is in being able to map a face from a 2D image…

Tell me more about this distinction between real tech and not real tech!

That sounds a lot like security by obscurity, one blog post later and the world can distinguish the two. Cvdazzle is unlikey to be the answer, it's just today's CAPTCHA to slow down face recognition, tomorrow's recognition will cut through that We need a more radical solution to devalue our private information. Consider by analogy cell phones: IMEI blacklists (in theory) fundamentally devalue stealing phones. What ca…

> if holding personal information was a big liability in the event of a leak, it would be prudent to keep as little as possible. But this kills the social network, and the cloud photo app, and a lot of other businesses. edit: nevermind, I think I misunderstood the suggestion. kardos's reply makes a lot of sense.

Not at all. People can opt-in and send their own photos, holding that data would be kosher. Holding photos of those who did not opt in, or those who explicitly opted out, would be where the liability comes in.

If we can penalize people for possessing some kinds of data (pirated software, movies, etc) in the name of defending someone else's copyright, or for not decrypting things, it can also be done in defence of personal privacy.
