For a while I’ve been saying that this whole national ID debate will be irrelevant soon. In the future you won’t have to show ID; they’ll already know who you are.
I used to specialize in biometrics and was underwhelmed at the actual capabilities compared to the marketing hype. And that was with people that weren’t even actively engaged in trying to defeat the technology. If someone really wants to defeat it the odds of success are very close to 100%.
“Novelty” contact lens easily defeat iris scans. Remote fingerprint scanning can be defeated with Band-Aids (or just the sticky tape part of it). More sophisticated/determined people will use contact lens with someone else’s iris pattern and be wearing someone else’s fingerprints.
The bottom line is that for the average person they might be able to know who you are and where you have been. Great information to use against your political opponents and for stalkers with access to the databases but useless for stopping smart and determined criminals.–Joe]
