A sliding-window dynamic frameproof code is a scheme for discouraging the piracy of digital broadcasts through the use of digital fingerprinting.  ...  In this paper we formally define sliding-window dynamic frameproof codes and provide optimal constructions for a certain class of these schemes.  ...  Construction of a Family of Sliding-Window l-Dynamic Frameproof Codes Construction 3.2 yields a q-ary sliding-window l-dynamic frameproof code protecting (q − 1) l−1 users.  ...
