| 摘 要： | 基于二进制随机编码技术,提出了一种简洁有效的合谋容忍数字指纹编码和跟踪算法.从理论上推导了算法的编码长度、合谋人数以及跟踪算法错误概率之间的关系,给出了错误概率界.在不同的应用场合,对于给定的任意小的错误概率,可以通过适当选取编码长度,使得在抗一定合谋攻击强度的情况下,错误概率满足应用要求.相对于已有的二进制随机编码指纹算法,在同样的错误概率下,本算法的数字指纹编码长度得到有效缩短.

| Abstract: | Based on random binary codes, a digital fingerprint coding and tracing algorithm is proposed. Performance of the algorithm is analyzed theoretically; relation between error probability and code length when anti different collusion size is given. Compared with existing random codes for digital fingerprint, under the same collusion size and error probability, the algorithm shortens digital fingerprint length greatly. |
