Biometric Template Security Using Invisible Watermarking With Minimum Degradation in Quality of Template
In this paper, the authors present an approach to enhance the Biometric Template Security by using Invisible Watermarking. For embedding the watermark in the Biometric Template, they used Parity Checker Method. The use of Parity Checker Method ensures that the change in Biometric Template should be minimum. The watermark that is embedded in the Biometric Template may contain person's name, person's address or some unique features of the person. The same watermark is embedded four times in the Biometric Template to enhance its security so that if one watermark is changed by attacker, the other watermark remains intact.
