摘　　要：分析了多媒体产品的完整性认证和版权保护存在的安全问题,简要介绍了数字签名技术以及RSA公钥密码体制,探讨了数字签名技术的具体应用并进行了安全分析。鉴于数字水印的特点,提出将数字水印技术与数字签名技术结合构成一套基于数字水印的数字签名系统,对系统进行了可行性分析,阐述利用VC++和MATLAB软件设计该系统的实现过程。This paper analyzes the security problem of integrality authentication and copyright protection in multimedia production, and introduces digital signature technology and RSA public cryptosystem in brief. It discusses and analyzes the applications of digital signature technology. Considering the specialty of digital watermarking, it brings forward integrating digital watermarking with digital signature to form a digital signature system which based on digital watermarking. Then, the feasibility analysis of the system is carried through. Finally, the system is designed and implemented by using the VC ＋＋ and MATLAB software.
