This work presents a new Digital Rights Management (DRM) architecture to address rights transfer and revocation aspects of protected content using a threshold Attribute-Based Encryption scheme. We considered two scenarios for rights transfer, here. In first case, a legitimate user needs to consume the protected content on multiple devices, while in second case the user wants to transfer the rights on the content to another user. These scenarios are significant in today's context with the proliferation of smart gadgets and shared cloud services. The architecture is flexible, offers individual or group level access to the protected content and does not require any pre-binding of the devices for consumption. The design inherits this feature from ABE scheme itself and therefore, it is possible to enforce controlled access for individuals as well as groups. Simultaneously, the architecture presents an efficient revocation scheme that eliminates the need of issuing new keys to users or re-encrypting the existing content, either for rights transfer or access revocation. Further, no specific revocation list is to be maintained for revoked users.
