The Study of Network Authentication Methods Based on Palmprint and Digital Watermarking

Abstract

Semi-fragile digital watermarking is able to distinguish between accidental attacks and malicious tampering, thus been closely watched in terms of multimedia content authentication. From the perspective of combining digital watermarking technology and palmprint identification, using the hidden and semi-fragile features of digital watermarking and the invariance character of palm information, the two-factor network authentication can be realized. The authentication enhances network security, and it is also a strong authentication scheme. The paper put forward a network authentication method based on palmprint and digital watermarking. The digital watermarking algorithm based on logistic encryption and discrete wavelets transform (DWT). The experimental results show that the algorithm has good semi-fragile feature, it can determine the authenticity of the palmprint image, so the method increases the reliability and efficiency of user authentication.
