摘　　要：数字水印技术是保护数字产品知识产权的一个潜在解决方案,一个有效的数字水印方案必须能够解决版权保护和盗版追踪等相关问题。以前提出了很多著名的协议,大多都存在着缺陷。在Leietal.协议的基础上提出了一种有效的数字水印协议。该协议基于密钥共享和同态公钥密码体制的思想,有效地解决了消费者的权益保护、未绑定、盗版追踪等问题,并引进一个可信的认证中心CA,有效解决了共谋问题和买方参与纠纷解决问题。Digital watermarking is a potential solution to protecting intellectual property rights of digital products.An effective digital watermarking solution must be able to tackle the copyright protection,piracy trace,and other related problems.Several famous digital protocols are presented,and their deficiencies are pointed out.Based on the protocol proposed by LEI et al.,an effective buyer-seller watermarking protocol is proposed,which,with the idea of secret sharing and homomorphic public key cryptosystem,effectively solves the problem of customer＇s right-and-interest protection.The unbinding problem,the piracy tracing problem effectively.And with the introduction of trusted certification authority（CA）,the conspiracy problem and the problem of buyer＇s participation in the dispute resolution could be solved effectively.
