Abstract
We propose a novel biometrics cryptosystem where one can send and receive secure information using just the fingerprints. This cryptosystem is a judicious blend of the asymmetric cryptosystem like RSA and the symmetric fuzzy vault scheme having the advantages of both the aforementioned crypto systems. We have proposed a modification of the fuzzy vault scheme to make it more robust against variations in the values of biometric features. Finally, we propose the use of invariant features as a key to producing a hierarchical security system where the same key (fingerprint) can be used to generate encrypted messages at different levels of securityKeywords
