Fingerprinting Codes for Live Pay-Television Broadcast Via Internet
In recent years, with the rapid growth of the Internet as well as the increasing demand for broadband services, live pay-television broadcasting via internet has become a promising business. To get this implemented, it is necessary to protect distributed contents from illegal copying and redistributing after they are accessed. Fingerprinting system is a useful tool for it. This paper shows that the anti-collusion code has advantages over other existing fingerprinting codes in terms of efficiency and effectivity for live pay-television broadcasting. Next, this paper presents how to achieve efficient and effective anti-collusion codes based on affine plane and unital, which are two known examples of balanced incomplete block design (BIBD). Meanwhile, performance evaluations of anti-collusion codes generated from affine plane and unital are conducted. Their practical explicit constructions are given last. Key words: fingerprinting code, anti-collusion code, BIBD, unital, affine plane
