摘　　要：鉴于目前协议中存在的身份认证、版权追踪、买卖方工作量过大等问题,提出了一个基于身份认证的数字水印协议。在协议中引入了可信第三方,减少了买卖方的工作量;由第三方进行水印加载和数字作品的分发,有效防止了水印信息的滥用。同时,在水印中加入身份认证信息,并将各实体信息及时间戳放入一个安全的数据库中以便查询,在版权追踪时能更高效、准确地确认版权所有者。In light of the problems existing in current protocols, such as identity authentication, copyright tracking, excessive workload of buyer and seller, a digital watermarking protocol based on identity authen- tication is proposed in which a trusted third-party is introduced to decrease the workload of buyer and seller. Watermark embedding and digital products distribution by the third party could effectively prevent the abuse of watermarking information. Meanwhile, the adding of identity authentication information to the watermark, and furthermore, the storing of entity information and a timestamp in the secure database for later query could provide more efficient and accurate determination of copyright owner in copyright tracking.
