COMBINATION OF FINGERPRINT FOR PRIVACY PROTECTION: PRE-PROCESSING

Abstract

Biometrics is the measurement and statistical analysis of people’s physical and behavioural characteristics. Using biometrics to verify identity means using a physical characteristic such as face, voice or fingerprints to authenticate an individual’s claimed identity. Fingerprint matching is by far the most successful biometric technology because its ease of use, non-intrusiveness and reliability. Here we introduce a novel system for protecting fingerprint privacy by combining two different fingerprints into new identity. Firstly we extract the minutiae position from one fingerprint, the orientation from other fingerprint and reference point from both fingerprints. The coding strategy is applied and a combined minutiae template is generated and stored in database. In the authentication process, the system needs two query fingerprints from the same fingers which are used in enrollment. A two-stage fingerprint matching process is proposed for matching the two query fingerprints against a combined minutiae template.
