Title: Codes with traceability properties

Abstract: The talk will present codes with traceability properties. These codes are used in digital content distribution schemes to prevent dishonest users from redistributing copyrighted material. After showing that separation is a necessary property, we will move on to separating codes. In the crypto literature, separating codes have been rediscovered under the name of secure frameproof codes. We will gain some insight about both properties by discussing weaker versions, namely almost separating and almost secure frameproof codes. Silverberg, Staddon and Walker asked if for Reed-Solomon codes the separating property was equivalent to the stronger TA property. It will be shown that it is true for particular code parameters. The general answer remains an open problem.
