NOVEL METHOD FOR ROBUST KEY GENERATION FROM ONLINE BIOMETRIC SIGNATURE
Abstract
Existing symmetric encryption algorithms require storage of the secret
key. Stored keys are often protected by poorly selected user passwords or pin-
codes. Combining biometrics with cryptography is often assumed as a possible
solution. This paper describes a novel method for transforming an online
biometric signature into a binary vector, which can be used as a cryptographic
key. The method is based on a secure sketch scheme and makes it possible to
construct 16-bit keys with false accept rate and false reject rate less than 10%.
