Abstract This paper proposes an innovative pricing and timing method as a component of DRM to enhance the control of legal copy of digital information with delicate granularity. In the proposal, price is classified in according with different class of services for the same digital content. And it calculates adaptively the end of service period of a piece of digital information in order to prevent illegally use.
