Priority Watermarking-Based Face-Fingerprint Authentication System

In this paper, we propose a multi-biometrics authentication system based on our proposed priority-based watermarking method. We investigate how watermarking techniques affect the container, which is facial image used in further authentication steps. We conduct experiments on facial and fingerprint features using both priority-based watermarking method and non-priority-based method. Results show that the proposed priority-based watermarking method has reduced data retrieval errors from the facial image after decoding, thus it has also reduced authentication error rates.
