Abstract(in English) This paper proposes a distributed copyright protection system for digital content which is based on the idea of bounty hunting. The system employs a digital watermark method in which all information for extracting watermarks can be opened, so that any home page visitor can verify the authenticity of the content on the home page he/she is visiting. It allows, essentially, every net surfer to be a kind of bounty hunter who finds illegal content or home pages. We believe this type of self-policing system is necessary because it is impossible for a limited number of trusted parties to check the vast number of content in all home pages over the Internet. Moreover, in the proposed system, illegal home page owners can not know if or when they have been discovered, as each and every visitor has the potential to discover and report them. Therefore, this distributed-type check of the proposed system promises to be a much greater deterrent than a centralized-type check could ever be. Thus, a copyright protection on the Internet is successfully achieved by the system. This paper discusses the efficiency of a bounty hunting-based copyright protection system by comparing it with the related systems.
