A Novel DRM for Service Provider in Digital Reading

摘要

This paper presents a DRM for Service Provider to reorganize resource from different DRMs, in view of the present situation of Chinese digital publishing industry. This DRM helps SP to provide value-added service which could be quite different from CP providing, such as redistribution, recommendation, renting and so on. It repackages various DRM licenses and SP copyright control description into one unified SP license, and distributes this license to user. And Device client extract content to reform an exchange format file through calling CP DRM API. All SP license describing operations can be executed on this file, without CP being involved. We also implement the DRM and evaluate it with an experiment. The experiment results demonstrated that our design is feasible and valid.
