一种用于DRM的指纹嵌入和解密集成的实现方法研究

多播环境下,指纹嵌入应用技术是目前信息安全研究的焦点.在信源传输端嵌入指纹影响了系统的可扩展性;而在接收端嵌入指纹,系统增加了对用户的要求.综合考虑,本文针对DRM提出了一种新的指纹嵌入和解密集成的一体化技术实现方法.该方法嵌入的指纹是不对称密钥结构的相关函数,能满足通信时系统对实时性和鲁棒性的要求.

Study on implementation of integrating the decryption and fingerprinting embedding for DRM

The fingerprint embedding is recently research key of information security in multicast environment. Transmitter-side fingerprint embedding method suffers from poor scalability. Receiver-side fingerprint embedding may have additional burden to consumers. The paper proposes a novel implementation of Integrating the Decryption and Fingerprinting processes The fingerprinting embedded by the method is a function of correlation of asymmetric key scheme and satisfy the system need for real-time and robustness.
