摘要：In this paper, we present an approach to enhance the Biometric Template Security by using Invisible Watermarking. For embedding the watermark in the Biometric Template, we used Parity Checker Method [2]. 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. For each biometric template there will be a secret key that is used for embedding of watermark. The maintenance of secret key will be responsibility of database manager. The same key can be used for all biometric templates which reduces the responsibility of database manager up to a greater extent but at the cost of security. So, we used the separate key for each Biometric Template.
