摘　　要：通过设计一种数字指纹的线性无关特征码,提出基于协同学的残留特征跟踪的抗合谋数字指纹,将协同学应用于数字指纹的合谋跟踪,建立了一套基于残留特征跟踪的抗合谋数字指纹方案.实验结果及分析表明,该方案能够在大幅度提高数字指纹的编码效率和跟踪效率的同时,基本上保证数字指纹的鲁棒性和抗合谋性.This paper creates a kind of linear independent Synergetic, which applies Synergetic to digital fingerprinting, character code, presents a new theory based on and then proposes a scheme of collusion-resistant digital fingerprinting based on residual characters tracking. The efficiency and the performance are proved and analyzed by theories and examples. The experimental results indicate that the proposed method can greatly improve the efficiencies of encoding and tracing in the digital fingerprinting. The performance in robustness and collusion-resistant is able to meet the requirements of the applications of digital fingerprinting.
