Defeating face-recognition systems

That wouldn't work, even if someone actually wanted to go that route. The facial features are all exposed except the nose.

Prosthetic makeup, on the other hand, would probably work very well if enough of the face was covered. If done right, it might not even look like a disguise.

Really? Even with the eyebrows being in a different place, the nose being majorly different and the lips being drawn differently from reality?

Huh. I have no idea how this thing works, obviously.

You're a meany-pants.

I know you are, but what am I?

Or just grow out a real beard

If I could grow beard it would look very strange on me.

These systems work similar to skeleton and facial tracking setups in the movie industry. I could write one in Flash in about a day. They take a set of markers and place them at key points on the face, do a bit of trig to have a straight on profile and do some quick calcs to get the various ratios and then do a lookup search for similar parameters and the recursively check through those to get the closest match. This can be beaten with simple makeup. If yer nose is crooked then get a highlight pencil and crook your nose opposite with a highlight line or make it straight. Adjust the shadowing of your eyes. Again. a liitle bit of dark here and some light there and to the software your face topology has changed. As well if the camera is using YUV colorspace which most surveillance cams do then you can kill the luminance channel and defeat the tracking with a layer of reflective light blue (tammy faye eye makeup) which essentially will turn the facial image into a blue screen/green screen. They used this technique for graphics and secondary image insertion by coloring a portion of the screen with that blue and inserting and image into the screen at that ratio and screen position.

U should wear a burka.

CAREFUL THERE!

In the war against our freedoms, we must comply to the terrorist's rules, 100% in compliance, so they won't attack us...
Therefore, only women must wear the burkas. Beards may be required for the men in some instances.

Wearing novelty glasses with an attached fake nose and two fake eyeballs on springs, is still completely optional.

if you want to defeat these systems, get a job running them and be about as competent at it as your average government worker
