指纹识别系统允许追踪非法重新分发的多媒体内容。当使用非对称指纹识别时,商家既不知道标记的副本,也不知道嵌入的标记,因此商家不可能欺诈性地分发内容——这可能导致欺骗诚实的客户。经典非对称指纹协议部署的一个问题是,它们基于信息传输方法,如果不是不可实现的话,实现起来很困难。我们提出了一种通过对称(因此可实现)方案和可信第三方(TTP)获得非对称指纹的体系结构。
Fingerprinting schemes allow tracing of illegally redistributed multimedia contents. When using asymmetric fingerprinting, the merchant does not know the marked copy nor the embedded mark, so fraudulent distribution of the content by the merchant - which could lead to framing honest customers - is not possible. A problem with the deployment of classical asymmetric fingerprinting protocols is that they are based on information transfer methods whose implementation is difficult, if not infeasible. We propose an architecture to obtain asymmetric fingerprinting through symmetric (and thus implementable) schemes and a trusted third party (TTP).
