Unlinkable content playbacks in a multiparty DRM system (bibtex)
by Ronald Petrlic, Stephan Sekula
Abstract:
We present a solution to the problem of privacy invasion in a multiparty digital rights management scheme. (Roaming) users buy content licenses from a content provider and execute it at any nearby content distributor. Our approach, which does not need any trusted third party - in contrast to most related work on privacy-preserving DRM - is based on a re-encryption scheme that runs on any mobile Android device. Only a minor security-critical part needs to be performed on the device's smartcard which could, for instance, be a SIM card.
