基于数字权限管理的指纹视频技术研究

Research of Video Fingerprinting and Encryption Principles Based on DRM

在部分加密的基础上,说明了数字指纹嵌入和视频加扰编码算法结合的应用算法。提出了一种新的指纹嵌入和解密集成的一体化技术方案结构。

In muhicast distribution, the application of multimedia fingerprint becomes recently the focus of research in technology for information security. The paper provides a joint approach of digital fingerprint and video scrambling algorithm. Considering the necessary design tradeoff between practicality and security, we put forward a novel architecture of joint fingerprinting and decryption for digital rights management （DRM）.
