Abstract
A novel system used for fingerprint privacy protection by creating a new fingerprint identity and thrashes the user identity within the fingerprint image. A combined minutiae template containing only a partial minutiae feature of each of the two fingerprints captured in the enrolment phase, will be generated and stored. In the authentication process, a two-stage fingerprint matching process is proposed for matching the two query fingerprints against the enrolled template. Construct a new virtual identity, combined fingerprint by reconstructing the combined minutiae template having similar topology with it. The Dual-Tree Complex Wavelet Transform (DTCWT) domain is used to thrashing the user identity. Experiment results show the robustness of the algorithm against image rotation and different types of image noises.
