Fingerprint authentication by hybrid DWT and SVD based watermarking

This paper represents a hybrid DWT and SVD based biometric watermarking algorithm which is useful for embedding watermark i.e. binary equivalent of minutiae of fingerprint into cover fingerprint image. Here we choose lower resolution band for embedding watermark as watermark detection is computationally effective at lower resolution band. The proposed algorithm can satisfy both the main objectives of watermarking system i.e. transparence and robustness very well and even in the presence of various image processing attacks useful information can be extracted accurately from fingerprint images.
