What I hear in your comment is that if you want to steal people's fingerprints, you'd have to target-advertise them a clone of fruit ninja, possibly designed so that certain specific angles of fingers are clearly optimal for doing well at the game.
- kurthr 3y agoIf you want to steal a single print, you would need a moderately long game and pliable player along with wide angle synchronized video that imaged hand/finger orientation. If the video isn't good, or they use different fingers intermittently, or only one orientation, or they have a callus on their finger, or they have very fine/course ridges, too many forks/ends, an irregular accidental whorl or arch, or there's noise, etc... you wont' get a single print with high enough resolution to match. That still may not be a print they use for authentication. Most people use their forefinger or a thumb to swipe, and their thumbs to match/type, and multiple fingers or both thumbs to scroll/zoom. More interesting is that if one had full knowledge of a persons prints then perhaps with microphone, touch tracing, and wide angle video, one could compare expected vs measured sounds. This is a one-one confirmation rather than one-many match. Perhaps it could prevent long term usage after a person had unlocked their device and another was using it.
