Abstract
Exchange of Digital Rights Management protected content between two devices without the need for a third party. Each user marks a license as unusable and the devices the trade licenses. A user then instructs the device to import the received license. The device verifies that a license has been rendered unusable and only then erases the unusable license and enables the device to use the new license. The content associated with a license may be traded before or after the license exchange, and may also be downloaded from a third party. Also provided is a device for exchanging licenses.
