| 摘 要： | 与数字指纹相关的指纹编码、嵌入、共谋用户识别3个环节已有一定研究成果。若数字指纹走向实用,则还需解决一个问题:抗共谋数字指纹实现问题。详细阐述了该问题的涵义;分析了抗共谋指纹编码、内容分发机制及终端消费环境对该问题的影响并探讨了相关解决方法;从通信代价、计算及存储代价等软硬件成本、安全性及实时性等方面对现有典型抗共谋数字指纹实现算法的性能进行了比较分析;最后,讨论了该领域的未来研究方向。

| Abstract: | Considerable progress has been made in fingerprinting technology,particularly with regard to fingerprinting codes,embedding methods and colluder identification.But applying fingerprinting technology to engineering,it faces the problem on how to realize anti-collusion fingerprinting in real system.The concept of anti-collusion fingerprinting realization was introduced firstly,and then effects of three factors on it were studied.These factors are anti-fingerprinting codes,content delivery system and user's mu... |
