Paper Abstract

We propose a phase-encoding-based digital watermarking technique for fingerprint template protection and verification. We extract a signature from the one-dimensional Fourier phase of the original fingerprint image (template) and then embed it back into the image using a variation of phase-shift keying modulation and the spread-spectrum method. To minimize the degradation to important minutiae features of fingerprint data, we segment the template into a region of interest (ROI) and a region of background (ROB) and embed the watermark adaptively in these two regions using an adaptive phase quantization method. We give experimental results with fingerprint biometric data that demonstrate the protection of fingerprint templates as well as the verification of fingerprint recognition.
