Encryption and authentication schemes suffice for the security of information stored or exchanged by different par-ties, but secure key generation and distribution is a highly non-trivial matter in cryptography. Fuzzy extractor is a security primitive, which can be used to encrypt and authenticate a message using the users biometric b1 to reproduce extraction of an almost uniformly key from non-uniform source such as fingerprint and iris, voice sample, etc., is allowed to decrypt cipher texts created by biometric b, if and only if the two sets b and b1 are close to a measured set-overlap-distance metric.
