A Novel approach for securing biometric template

Template and database are critical parts of biometric systems. Attacker usually afflict biometric template. There can be various attacks on different modules of biometrics system and communication links among them. Securing templates from these attacks have become very important or imperative issue. Security is achieved by methods of cryptography, which deals with encryption of data. Encryption is the process of encoding messages (or information) in such a way that eavesdroppers or hackers cannot read it, but that authorized parties can. In this paper, we present an approach to enhance the invisible watermarking technique with cryptography. The biometric trait is modified using invisible watermark information and is further secured using cryptography. The encryption algorithm which has been used is highly suitable for multimedia as well as text data. We can use different encryption techniques like AES, MAES etc .The template is made more secure using encryption and finally stored in database.
