The Designing Of An Identity-Authentication System Using The Fingerprint And User's Information As The Watermark

Authentication is the first protection of the information system security field.It is an inportant research in the information age.Based on summarizing the traditional development and technical character about user anthentication,the digital encrypt technology,user fingerprint identification and digital watermarking are analyzed and studied deeply.The paper proposed a user authentication system based on the fingerprint and user's information as the watermark,the detail is as follows:1.Design an authentication protocol based on the fingerprint minutiae and digital watermarking encryption.In order to protocol security,the paper determines authorship or authenticity of the protocol,describes the execution process of the protocol.One of its innovation is that this protocol is respectively using didital signature and information eigenvalue to do identity-authentication,and the public-key and symmetric-key encryption system ensure the security of information data in transfer and store;the second innovation is the protocol can successfully avoid the two common attack measures:stolen-verifier and replay,through introducing entering serial number,which can improve the secrecy and authenticity in registration and authentication,and greatly reduce the burden of users.2.Develop an identity-authentication system using the fingerprint and user's information as the watermark.According to the requirments of the protocal,it describes in detail the design of identity-authentication system and its functional modules,and gives an example of execution.By the information of fingerprint character and the information of users' data,this system create the digital watermark signal,which is concealed in the transferring carrier pictures.Using carrier picture as the carrier of digital watermark highly improve the security of the whole net identity-authentication system.
