Abstract

The licensing of digital assets is an important aspect of modern markets like music and movies. In this context, Digital Rights Management (DRM) and Traitor Detection (TD) comprises a set of tools, techniques, and processes that try to ensure control of the use of licensed media. This work contributes to this area by making it possible for DRM and TD to happen in a public and highly decentralized blockchain under a proposed threat model by developing new cryptographic techniques which, as shown by the results obtained, are very efficient without requiring expensive hardware.
