Using the Digital Signature of a Fingerprint by an Elliptic Curve Cryptosystem for Enhanced Authentication

摘要

Finger prints are widely used for the purpose of identification, with various interfaces such as personal computer logons, access control mechanisms, and the tracking of offenders from the scene of a crime. Furthermore, fingerprints have performance advantages over other means of authentication in terms of cost benefits, device sizes, and convenience of use. Some issues still remain unresolved with respect to the use of the fingerprint authentication process. The standard process involved in the comparison of fingerprints that needs assessment with those from a database still could benefit from enhancement. We suggest the use of digital signatures through elliptic curve cryptosystem that is embedded with the fingerprint, which can provide enhanced authentication and security.
