I accept that to some degree this will depend on the software/exact processes used, but I'd like a general idea as to how "risky" it is, and get a better understanding of how biometrics simplifies matching elements.
I wish to maintain a low profile online, but there are communities where it would be useful for people to have a picture if me. My concern is that photo being used to identify me in "real" photos to track me and link my online profile with meat space friends via facial recognition.
I postulate that using a caricature would provide some protection.
Am I correct in assuming that a hand drawn caricature will not leave meaningful markers for facial recognition software, even if they are highly recogniseable to people who subsequently meet me? How much more recogniseable would a photo turned into a caricature digitally be?
Are there key size guidelines to consider for ? (I assume a 32x32 pixel avatar will convey less identifiable info then a larger pic, but is there any "safe" size for an avatar/low res photo - or - I guess another way to ask is how many pixels of a face are required for AI software to get a statistically useful - for unique identification purposes ?
Similarly, can I assume that 16 colors will yield up to 4 times as much data as black and white - and is there much difference between 256 and 64k color?
