联合指纹嵌入与解密方案的性能研究
On the Performance of Joint Fingerprint Embedding and Decryption Scheme
摘要：
到目前为止，很少有人对联合指纹嵌入和解密方案的性能进行分析。本文对Kundur等人提出的联合指纹嵌入和解密方案的安全性进行了分析和改进。分析内容包括：对非授权用户的安全性、对授权用户的安全性、安全性与鲁棒性的关系、鲁棒性与不可感知性的关系以及感知安全性。在此基础上，提出了多密钥加密和DC系数加密等增强方案。该方法可用于分析其他JFD方案。希望能为JFD方案的设计提供有价值的信息。
英文摘要：
Till now, few work has been done to analyze the performances of joint fingerprint embedding and decryption schemes. In this paper, the security of the joint fingerprint embedding and decryption scheme proposed by Kundur et al. is analyzed and improved. The analyses include the security against unauthorized customer, the security against authorized customer, the relationship between security and robustness, the relationship between secu-rity and imperceptibility and the perceptual security. Based these analyses, some means are proposed to strengthen the system, such as multi-key encryp-tion and DC coefficient encryption. The method can be used to analyze other JFD schemes. It is expected to provide valuable information to design JFD schemes.
