A license transfer system for supporting content portability in digital rights management
Current digital rights management systems typically bind the right to use content to a particular device whose location cannot be changed easily. Users may find it difficult to acquire a new license for each device. We propose a license transfer system that allows the user to share a license between devices and uses transaction track files to ensure that only one device can use the license at a time. We analyze the security properties of the proposed system.
