However these emerging trends did not benefit the content providers because of their copyrights had been violated. This drawback restrained the development of the digital content market. The content providers would need some mechanisms to enforce access policies and to enable the consumers for better utilizing the licensed contents with extended allowances. The approach, DRM (Digital Rights Management) system was proposed to resolve these related problems. The DRM system is a system to protect and manage digital contents, and to control the usage and distribution of digital contents. It is intended to only allow proper authorized user to access the protected digital information.
Although DRM systems have already prevented digital contents from unauthorized access, it is still insufficient to provide the adequate functions to address the “Transfer Rights”. For example, the possible transactions of digital contents might occur at rental store, secondhand market, etc. These traditional business behaviors were not well considered and put into design of current DRM systems. This ignorance definitely lowered the consumer’s desire for purchasing the DRM protected contents. Furthermore, consumer still cannot resell copyrighted contents arbitrarily within the existing DRM systems. This limit violated the common use of property in a real world. In this thesis, we proposed an enhanced mechanism in which the “Transfer Rights” should be allowed in a DRM system. Based on implementation of transferable rights in DRM systems, we proposed two new business scenarios. One is an “e-Learning Content Rental Store” in which consumer is able to rent the e-Learning content media via on-line. The other is “e-Learning Content Secondhand Store” in which consumers can resell the e-Learning content media, specifically for those they purchased from others. These two proposed scenarios would enable the transferable rights with more reasonable and legal use in the DRM systems.
