摘　　要：提出了一种基于混沌序列的二进制指纹编码方案,在指纹嵌入技术研究中,提出一种基于小波变换及Gold码扩频的指纹嵌入算法,并提出了相应的指纹提取算法,实验结果表明该指纹系统在一般的多用户合谋攻击下能够有效地对合谋用户进行跟踪。This paper provide a fingerprint generating algorithm based on binary chaotic sequence.In fingerprint embedding,we adopted the DWT technique and spread spectrum algorithm that make the fingerprint embedded into data imperceptible and robust,and in the extracting process used correlating algorithm.The experiment verified that our fingerprint-coding scheme has good capability to trace users who attacked the system by collusion in usual ways.
