摘　　要：设计了一种基于LUC公钥密码体制的联合数字水印方案.在该方案中,各参与者用LUC公钥密码体制共同计算水印信息嵌入的位置来嵌入水印、水印执行者可验证参与者的身份,因此该方案能防止参与者的欺骗.此外,该方案还能实现水印的盲提取.实验结果表明,该方案对JPEG压缩、高斯噪声、椒盐噪声等攻击具有很好的鲁棒性.A novel digital watermark scheme for joint ownership based on the LUC cryptography is designed. In the scheme, with LUC public-key cryptography, each participant computes the watermark embedding block to embed watermark information, and the identity of each participant is verified, so the scheme can prevent participants from cheating in the watermark embedding and extraction process. Moreover, the scheme can achieve blind extraction. The experimental results show that the proposed scheme is robust against some attacks such as JPEG compression, Gaussian noise, salt and pepper noise.
