摘要
A biometric verification device is arranged to compare a reference hash with a verification bit string obtained from a biometric. The biometric verification device includes a candidate bit string generator arranged to generate candidate bit strings from the verification bit string and error probabilities; a hash unit arranged to apply a cryptographic hash function to the generated candidate bit strings to obtain candidate hashes; and a comparison unit arranged to verify if a candidate hash generated by the hash unit matches a reference hash.
