Can Big Brother identify your face from street-level CCTV surveillance and tell whether you’re happy, sad, or angry? Can that identification lead to your arrest on an outstanding warrant? What are the odds that the identification is incorrect, and really connects to someone else? Can you defeat the surveillance entirely using some trick?
On the flip side, can you get into a vault protected by a camera and facial identification software by holding up a print of an authorized person’s face? What if you put on a 3-D mask of an authorized person’s face?
