Home Secretary Requests Fingerprint-Activated iPods
John Reid, Home Secretary, has called upon tech manufacturers to improve the security on their gadgets to help with his recent push to frustrate criminals. Inviting Apple, Sony, and several others to his crime fighting summit Reid hopes to attack the rising robbery numbers in the most recent Home Office figures.
...because nobody would ever find the owner's fingerprint in their home!
This is yet another case of legislation coming up with the wrong solution to the right problem.
One of the biggest problems with biometric authentication is the lack of ability to revoke a compromised biometric key. Sure you can revoke rights based on a fingerprint, but then you've no way to use it again. Lifting fingerprints with gelatin isn't really that hard.

Personally, I think biometrics are great as a username equivalent, but should not be relied on for authentication. There is sound reason to have (1) something you have with (2) something you know in a good authentication system. The ability to revoke and re-generate either component is needed.
