The act of breaching copyright is probably the most common civil offence, and is often not considered as being unlawful by the perpetrator. The revenue that is lost by a copyright owner when illegal copying takes place can be significant. Losses may become unacceptably large in the future given the expected explosion of computerised, multimedia services. This paper discusses the problems copyright owners face when trying to maintain cost-effective control of their copyright in a digital age. It then proposes an initial model of a software-based system that provides copyright protection of multimedia information when delivered by Internet-based services.
