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/camera.html 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

  Or maybe infrared reflecting material similar to sun block. The local cancer society came to my workplace to promote skin health and one of the items was a small camera system. You put sun block on one part of your face, stuck your head in a box and a camera and screen showed the sunblock as black paint. If an IR type of material could be made you could paint geometric dazzle type paint on your face to obscure its geometry.

    Slick idea - I'd be concerned tho that, given the semi normal rough distribution of heat on the face (there's a reason head wounds bleed so much) that this attempt to game the system would be easily detected as gaming the system. The good news is any idiots building a product by bolting together parts from OpenCV that they barely understand would probably fall for it. Me, I'd be embarrassed if I didn't tag you as anomalous. HOWEVER - if you were really really good and accurate with the application of the blocker (cause if its zinc oxide it does work in both directions) and you backed it up with makeup for the visible light side of the house, you probably could fool most by establishing a completely different facial geometry. Anyway, certainly a concept worth ruminating on. :-) I think it would beat me at my imaginary best if done well. Have to find a counter, I guess.. Like gait :-)

  Nice catch - I was completely oblivious to it till you pointed it out, and it was an accident, I swear! Lazarus Long says punsters and practical jokers get keelhauled or staked out on anthills :-( That's no fun
