Although the "we have no idea" bit is hyperbole because the reality is we do know how unique fingerprints are. Francis Galton did substantial scientific research on fingerprints back in the late 1800s. He estimated the chance of two people having the same fingerprints at around 1 in 64 billion. Take that part of the article with a salt lick (and shame on Scientific American for not calling that out) and look to the parts where it describes the specific circumstances needed to force a collision. Still, the closure contains good advice. When a chain has only one link you know exactly where to look for that weak link. :) > Meanwhile, as voice synthesis improves in fidelity... That's only part of it. Even if (when) you can accurately reproduce any arbitrary person's voice there is still the playback mechanisms. Voice coils are mechanically incapable of exactly reproducing sounds. Even the best speakers can be identified as speakers if your hearing is sensitive enough and you know what to listen for. On the flip side of that, if you inject the synthesized data stream directly into system, bypassing speaker and microphone, it can still be detected as a fake because it will lack the analog distortion expected from the handset mic. -- Rich P.
