Many kinds of content are digitized， such as audio， video and books. The industry of electronic book is boosting rapidly in the past years， while at the same time， as a special kind of eBook used in education area， electronic textbook is raising wide attention in both academia and industry. Copyright protection is always a question together with digitalization. This is due to the natural properties of electronic content that it is easy to copy and transmit. Almost at the same time when eTextbook is proposed， industry is studying copyright protection method for it， while digital rights management， is a method mostly widely used. Digital rights Management， normally abbreviated as DRM， is the technology used by copyright holders or their representative intent to control the use of digital content after sale [1]. In the history of DRM， Philips is always a key player. Philips has a lot of intelligent property in this area and is core member and key technical contributor of Marlin DRM community [2]， the most widely used open standard DRM solution in the world. In China， our team did a lot of job in the DRM standardization and proposing. We are key DRM solution contributor in standardization work groups such as ChinaDRM， IGRS， GAPP eBook and ETESBS， the corresponding areas including DRM for video， audio， eBook and eTextbook. Generally speaking， DRM method should be content independent. A good DRM method for media content should be available for eBook and eTextbook too. However， when extended to a new area， we should analysis the new requirements so as to adjust and make the DRM solution more suitable and effective. In this p
