Abstract
Embodiments of the present disclosure relate to digital rights management. A method for managing rights transfer of using digital content from a first device (120) to a second device (130) is proposed, comprising generating at an authentication device (110) a first authentication dataset C by encrypting a first verification code R1 using at least one public key for at least one device blacklisted by the authentication device (110). The first authentication dataset C and a second verification code R2 are provided from the authentication device 110 to the first device (120) and a response message M is returned from the second device (130) to the authentication device (110). The method also comprises verifying validity of the second device (130) at the authentication device (110) based on the received response message M. In accordance with embodiments of the present disclosure, the DRM protected digital content can be shared with high security, while the recipient is kept anonymous to the DRM server.
