Enhanced Security Using Biometrics and Elliptic Curve Cryptography

Abstract

Biometric Systems are systems which acquire, process, analyze and match Biometric credentials with those that are present in the Database providing Verification and Validation.Nowadays, simple biometrics like fingerprints and face recognition can be replicated with some effort. This compromises the level of security. However, combining two or more features like Fingerprint and Face as an authentication parameter, we can group together the features which will significantly increase the level of security as it will be much harder for unauthorized people to replicate both fingerprint and facial characteristics of a user. This paper discusses the systems which provide secure verification to incorporate the method with Elliptical Curve cryptographyusing Genetic Algorithm. Elliptic Curve Cryptography is based on a curve which is generated such that a line passing through any two points of the curve will surely pass through a third point somewhere along the curve. Points generated using Elliptic Curve cannot be regenerated by reversing the algorithm. This makes it very secure to generate encryption keys.
