Securing Multiple Information Using Bio-Chaotic Keys

To advancement in security applications, for the first time, a bio-chaotic key generated from the emerging biometric trait “finger knuckle print (FKP)” has been proposed for data security and authentication. In the system, the feasibility to generate multiple keys from the single FKP image has been exploited to secure multiple information, which results in significant enhancement of the security strength. The encryption and decryption processes keep the user-specificity and perform better in reducing space for key storage and transmission. The research contribution is to facilitate a simplified optical implementation. Simulation results show the validity and effectiveness of the proposed scheme.
