Convolutional fingerprinting information codes for collusion security. Journal of Software, 2006,17(7):1617−1626. /1000-9825/17/1617.htm Abstract: Digital Fingerprinting is a technique for the merchant who can embed unique buyer identity marks into digital media copy, and also makes it possible to identify “traitors” who redistribute their illegal copies. At present,the fingerprinting scheme generally has many difficulties and disadvantages for large-size users, involved in code construction with shorter length and effective traitor-tracing. To resolve these problems, this paper presents the definition of Fingerprinting Information Code and a practical construction method by composing of convolutional codes and common fingerprinting codes based on
