can't remember where i read it. but apparently thick smoke / vape from a ecig is really effective at tricking facial recognition.. you just need to be able to constantly be exhaling a thick cloud of vape.. also block geometric shapes painted on your face messes up the program, cos it makes the points hard to measure or something. trying to find a link to back this up.
