摘要
现有的数字指纹协议主要基于Buyer-Seller模型,卖方拥有数字产品的原始拷贝,在数字产品中嵌入与买方相关的数字指纹,出售给买方。如果卖方发现了非法拷贝,根据提取出的指纹跟踪非法的买方。该文介绍了有别于Buyer-Seller模型的二次分发模型,在此模型基础上,引入防篡改硬件和对称嵌入技术,提出了一种可用于在线交易的、安全高效的数字指纹协议。
The available fingerprinting protocols are mainly based on the Buyer-Seller model. In the Buyer-Seller model, the seller is the holder of the original copy of the digital product. He embeds the fingerprinting relative to the buyer to make a new copy and sell the new copy to the buyer. When an illegal copy is found, the seller can extract the fingerprinting to trace the illegal buyer. This paper introduces a different model, the secondary distribution mode. Based on the new model, it employs tamper-proof hardware and symmetric encryption technology to design a secure and efficient digital fingerprinting protocol which can be used for on-line trade.
