Title Managing Copyright in Open Networks
Abstract Watermarking is often invoked as a tool for the protection of Intellectual Property Rights (IPR) of multimedia data distributed in digital form. The most important issues to be considered when designing a watermarking-based Electronic Copyright Management System (ECMS) are discussed here, and a new system is presented which integrates state-of-the-art watermarking with cryptography techniques to enable IPR protection in open-network environments. The proposed system is a self-contained one, in that, at any given time, the information needed to prove the legal/illegal use of the data is hidden within the data itself, whereas no attempt is made to trace previous abuses. Particular care is paid to grant to all the actors involved in the distribution of the protected material the possibility of demonstrating the legitimate use of the data in their hands. Some case studies are discussed that support the validity of the proposed approach.
