Nowadays Automated Fingerprint Identification systems are most widely employed in verifying / identifying the physiological characteristics of individuals. The traditional privacy algorithms are inefficient to ensure security as there is more chance of duplicating the single fingerprint. So to enhance security in this work, a system is proposed which advocates acquisition of two fingerprint images (from that of thumb and index finger) from a single individual. From the Acquired image, minutiae points from thumb finger and the orientation angle from the index finger are extracted. The combined minutiae template is generated by detecting the reference points from each which is used in Reconstruction Technique. The, generated template is stored in a Database. In the authentication, the system requires two query fingerprints from the same two fingers which are used in the enrollment. Matching Process is done by calculating feature distance of the two query fingerprints. Combined minutiae template is similar to the original minutiae template; it is difficult to distinguish both the template by the attacker.
