A new approach for biometric database management is presented with enhanced security features. This paper attempts to improve the security of biometric database system by interfacing with MySQL server. The signature templates are acquired for the database using digital pen tablet, encrypted using a simple pseudo noise based algorithm and then stored on the MySQL server. During the authentication phase, the signatures are brought from the database for feature extraction. After decryption, they are compared with query template. Since, the database is password protected, it provides double security against adversary attacks.
