COMBINATION OF FINGERPRINT FOR PRIVACY PROTECTION

Abstract

Biometric refers to the authentication technique which depends on the measurement and statistical analysis of people's physical and behavioral characteristics. Among all the biometric technique fingerprint identification is consider as most reliable technique as every individual has unique fingerprint. But as fingerprint technique is used in many authentication systems so protecting it becomes an important issue. Here a system is shown to protect the privacy of fingerprint by combining two different fingerprints into a new virtual identity. In enrollment phase, extract the minutiae position from one fingerprint, orientation from another fingerprint and reference points from both fingerprints, using this extracted information from a combined minutiae template and store it in database. In authentication phase use two query fingerprints, extract the minutiae position from one fingerprint, orientation from another fingerprint and reference point from both the query fingerprint. Perform a two stage fingerprint matching process to match the two query fingerprints with the enrolled fingerprint. With the existing fingerprint reconstruction technique a new virtual identity is created.
