Digital Fingerprinting Protocol for Secondary Distribution
Shengli Liu · Jisuanji gongcheng · 2007
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.
