报告摘要: Fingerprinting codes are used to protect digital copyrighted content. In this talk, we investigate two kinds of fingerprinting codes, that is, separable code and expanded separable codes. We discuss their upper bounds on the numbers of codewords, and construct a few families of optimal codes which attain these upper bounds.
