Untargeted Near-collision Attacks in Biometric Recognition. (arXiv:2304.01580v2 [cs.CR] UPDATED)
cs.CV updates on arXiv.org arxiv.org
A biometric recognition system can operate in two distinct modes,
identification or verification. In the first mode, the system recognizes an
individual by searching the enrolled templates of all the users for a match. In
the second mode, the system validates a user's identity claim by comparing the
fresh provided template with the enrolled template. The biometric
transformation schemes usually produce binary templates that are better handled
by cryptographic schemes, and the comparison is based on a distance that leaks …
