Life Imitates Art
It will no longer be feasible for an identity thief to cut off the finger of the victim to gain access to an object secured by biometric fingerprint, as happens in action movies. Sony's system doesn't use fingerprints, but an image of the capillaries available only when blood is pumping through the finger in question.
I've often wondered what role fiction played in inspiring fact. Companies often hire actors to use their products in movies. Copycat crimes follow every sensational or bizarre types of murder. So there's at least some basis for arguing that people ape what they read in the papers or watch onscreen. Maybe many of the horrors we experience today come straight from pulp fiction.
