Find a way to be an imposter to a real record. That is NOT hard to do. I have many years in the intel community where biometrics are used, and I can say with certainty that without STRICT controls they are unreliable. By strict, I mean controlled beyond anything a civilian authority can control, because such controls REQUIRE controlling the population the biometrics represents.
My previous post was to infer the horrible. We can loose the records that contain our identity, and without being able to verify that identity we will be prevented access to our personal information, such as credit cards or employment. Biometrics can also be played. By that, I mean look at the credit reports. they are screwed constantly, but at least people understand that and do not hold them in high regard. Biometrics would be. No record, no identity. People could screw you in a heartbeat by deleting your record. The movie “The Net”, was an excellent example of digital warfare. Erasing a n identity that is only supported by a biometric would be very dangerous and give the government the ability to control you.
You may think that a biometric would be anonymous, but it would not be, it could not be, and if it started that way, it would be soon converted to a positive identity system.
We do not need biometrics as we already know who is an alien.
