Untargeted Near-collision Attacks in Biometric Recognition. (arXiv:2304.01580v1 [cs.CR])
cs.CR 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 claimed identity by comparing the fresh
template with the enrolled template for this identity. Both the experimentally
determined false match rate and false non-match rate through recognition
threshold adjustment define the recognition accuracy, and hence the security of …
