| 摘 要： | 为了适应P2P协同工作中的安全需求，针对多媒体数据的特殊性，探讨了传统的多媒体认证方法，提出了一种结合数字签名和数字水印的多媒体信息认证方案，系统利用JXTA平台的安全特性，采用双重身份及易损水印的认证机制，使得非法篡改、伪造多媒体信息更加困难。分析表明，该方案具有安全性高、可信度高等特点，适用于图像、数据等多媒体的安全传输。

| Abstract: | In order to meet the security demand for P2P collaboration environment and the particularity of the multimedia data, a solution based on the digital watermarking and digital signature was put forward. This solution utilizes the security feature of JXTA platform and doubles entity authentication based on digital signature and fragile watermarking technique. It may prevent the illegal user from deceiving other users, at the same time also maintain the integrity of resources. Analysis shows that the proposed scheme has high security and trust. |
