一种结合Turbo码的离散数字指纹编码

A Discrete Fingerprinting Code Combined with Turbo

提出了一种具有抵抗不可见位攻击的二进制指纹编码,对由基于随机序列的编码算法产生的指纹序列进行Turbo编码,之后采用扩频理论对用户指纹进行调制,使离散编码算法在对误码情况的容忍性上有了一定的提高,具有较高的合谋容忍性。

This article proposed a binary code which has resistance to attack of invisible bits.The fingerprint sequences,which were produced by algorithm based on the random sequence,are coded by Turbo coder.After that,use the theory of spread spectrum to modulate fingerprints.In this way,the discrete algorithm tolerance to error code situation is enhanced and has higher tolerance to collude.
