A Face in the Crowd: Say goodbye to anonymity - CBS News: Over the last 10 years, the ability of computers to identify faces has gotten 100 times better, a million times faster, and exponentially cheaper.
Yet facial recognition technology is still a work in progress. While investigators in the Boston marathon bombing had multiple images of both suspects, the technology did not come up with a match. They were not identified by their faces, but by their fingerprints! Authorities won't say what went wrong. One possibility is that government data banks - through which the photos would've been searched - are not big enough.
