Authentication of Fingerprint Image Based on Digital Watermarking

Abstract

This paper presents an authentication method to establish the authenticity of fingerprint images by embedding the watermark data into fingerprint image. The method depends on the thinning file of fingerprint image in determining the appropriate locations in which the watermark bits will be stored in the original fingerprint image to preserve feature regions without any change, therefore the proposed method inserts watermark data in locations which not use in feature extraction operation thus prevents watermarking of regions used for fingerprint classification and recognition. The experimental results show the high visibility of the proposed method depending on the properties of human visual system. Our method is also efficient as it only uses simple operations
