Transmission of Secure Biometric Data for Network-based User Authentication

The large-scale utilization of biometric authentication systems creates a demand for effective and reliable security and privacy of its data. Biometric data is not secret and if compromised, it can have catastrophic effects on the integrity of the whole verification system. To address these issues, this paper presents a novel encryption and watermarking method by using public key infrastructure for the secure transmission of biometric data over network. Encryption is applied on the biometric template before embedding as a watermark to make it more secure and robust and then, it is hid into the cover image. Experimental results show that the security, performance, and accuracy of the presented method is encouraging comparable with the other methods found in the current literature.
