Frameproof Codes Based on The Generalized Difference Function Families
Qingjun CAI, Yuli Zhang · International Journal of Wireless and Microwave Technologies · 2011
The frameproof codes are used in copyright protecting.Motivated by the method of constructing frameproof codes coined by D.Tonien etal, in this paper, we introduced a new combinatorial designs which in fact generalized the difference function family introduced by D.Tonien.The new designs can be constructed from difference matrix efficiently.By using the new designs we construct more larger number of frameproof codes .
