Abstract:

This thesis puts forward a new model of network dual authentication. In light of the combination of the technologies of digital watermarking and finge rprint recognition,and taking advantage of the invisibility of digital watermarking and the uniqueness of fingerprint recognition, this model blends twophysical authentication factors, one being the user＇s ID and password and the other being the information of the user＇s fingerprint features, in orde er to realize the dual authentication of users＇ identification. This is a kind of powerful pattern of authentication,and greatly improves   nction of this algorithm through simulation experiments. In addition, it analyzes the process of fingerprint recognition and the amount of information o f watermarks embedded.
