As 3G networks provide enhanced capabilities of data transportation, a considerable amount of mobile applications and services, which involve mass of unstructured digital content, e.g., video, audio, are available. Meanwhile, pirate and illegal distribution of these digital contents are severe issues. Digital Rights Management (DRM) aims at protecting unstructured digital contents from being abused through regulating the usage of digital contents. However, existing mobile DRM schemes more or less suffer from poor compatibility, bad practicality or high cost. Besides, to the best of our knowledge, fewer of the existent DRM schemes concern for efficient unstructured data management. In this paper, we propose Phosphor, a cloud based mobile DRM scheme with sim card. In details, an unstructured data management system is adopted for efficient data management services in DRM backend (servers and systems). Meanwhile, sim card is introduced to Phosphor, which not only reduces the cost, but also provides higher security. We have implemented our DRM scheme, which demonstrates that Phosphor is efficient, secure and practicable.
