If the technology just stayed at facial recognition, maybe - I work on stereoscopic vision, so you'd have to change your head geometry too for my cameras if you're in parallax range..... and we're getting to the point of being able to do realtime skeletal pose analysis -- https://storage.googleapis.com/tfjs-models/demos/posenet/cam... So, it's an arms race :-/

Egad Batman! Thanks for the background - how would one change their head geometry? Would a prosthetic nose, or subdermal implants serve this purpose?

a hat and beard will probably be enough for next 20 years, after that we will probably have to resort to more advanced techniques like wigs

Probably - its an arms race after all - at this time for the stupider systems the following steps can confuse them 1 - use makeup techniques to make the nose fade into the face and don't let it get a profile view - noses are very important - a prosthetic nose probably won't help tho, cause the nose is an orientation characteristic more than an identification one

2 - eyes and the facial geometry around them are secondary, so no nose and giant movie star sunglasses adds to the machines confusion

3 - collar worn sparkle lighting directed upwards is baffling to machine - silly things keep picking up the light sparkles on the face as feature points (heh)

4 - makeup patterns based on the WW2 ship camouflage mess up geometry detection

Now, all of that will defeat a simple recognizer but if the developers had a lick of sense, the system will still pop it out as anomalous.

Mission impossible facial masks could certainly help, but pretty much everyone is removing the IR filters at this point and the facial thermography would be all messed up

Then there's all the work going on in recognizing more than just a face - I've seen some stuff on incorporating more of the body into the recognition pattern (I've always wanted to watch one of those systems misrecognize Mitch McConnell as a turtle :-) As the available horsepower continues to expand, more of the totality of the individual can be recognized (my own accidental contribution to this is that cheap stereoscopic vision makes it a lot easier/more accurater to pick out foreground from background) At the end of the day, I think Scott McNeally had it right in the '90s - "You have no privacy. Get over it" I am of mixed minds about this stuff in public spaces, the good and bad examples are evenly distributed

Masks and temporary/permanent face altering techniques will explode as this technology takes hold. I think about it like ad-blocking, something that may work itself into the mainstream despite it's questionable ethics.

Along with a corresponding explosion in legislation to prevent you from covering your face in public. It already exists in France (popularly known as the 'Burqa Ban', but I think it covers other face coverings).

I'm especially curious to see how this will go down in the UK, which is increasingly authoritarian while often painfully politically correct.

An ill-thought-out and ambiguous piece of law will be rushed through Parliament, with various exemptions for religious groups. The far right will become outraged about these exemptions, and stage protests. The "nothing to hide, nothing to fear" brigade will be out in force. The government will make vague statements about protecting us from terrorists. Paedophiles will definitely be mentioned at some point.

Eventually there'll be farcical prosecutions of people who were just cycling to work with a pollution mask, or going to a fancy-dress party. And the police will continue to claim they're under-funded, while somehow finding the resources to pursue bullshit like this.

Yep. And it's super cyberpunk. https://cvdazzle.com/

Thanks for sharing. This is excellent!

Masks, face altering, stickers, etc. I like this research about "Adversarial Patches" - stickers that confuse image recognition systems. I imagine one may wear a display with ever changing images that are salient and confuse such systems.

I think they mean surveillance cameras run at an angle that makes automated facial recognition impossible.
