摘要: 为实现利用数字指纹追踪超分发者,提出一种支持加密和指纹互操作的多媒体安全分发方案。将8×8离散余弦变换系数分为4个部分,每个部分采用不同的加密方法。数字指纹直接嵌入AC的中频系数中,并能在解密后从明文中正确提取。实验结果证明,该方案具有较好的指纹不可感知性、合谋安全性及鲁棒性,且加密算法的安全性较高。

Abstract: In order to use the digital fingerprinting to trace the user’s super distribution, this paper proposes a secure multimedia distribution scheme which supports the interoperable encryption and fingerprinting. It divides the 8×8 Discrete Cosine Transform(DCT) coefficients into four parts, and every part is encrypted with different methods. The digital fingerprints are directly embedded into midband coefficients of AC, and can be extracted after the decryption correctly. Experimental result verifies that the scheme gains the properties of imperceptibility, collusion security and robustness of fingerprints, and encryption algorithm is secure.
