Biometric Encryption

Given the recent explosion of interest in human authentication, verification based on tokenised pseudo-random numbers and the user specific biometric feature (BioHashing) has received much attention. BioHashing gains a significant performance improvement over solely biometrics (i.e. zero equal error rate); the main drawback of the base BioHashing approach relies in exhibiting low performance when an "impostor" B steals the hash key of A and he tries to authenticate as A. In 2005, BioLab introduced some ideas to improve the base BioHashing approach in order to maintain a very low equal error rate when nobody steals the hash key and to reach good performance also when an "impostor" steals the hash key.

BioHashing generates a vector of bits starting from the biometric feature set and a seed which represents the "Hash key".
