Abstract

In most current digital rights management solutions, digital license is bound to the content rendering device using its hardware configuration. However, this strategy introduces an adaptive problem: protected contents can't be used any longer once the user changes the hardware configuration. This paper focuses on the problem and presents a feasible adaptive approach. With our approach, digital content buyers can still smoothly render the bought digital content without any extra operation when partial hardware replacement arises. Our approach balances the needs of customers' hardware alteration and providers' copyright protection on a reasonable level and increases the flexibility of DRM system.
