Abstract

A method for digital rights management for a copyright work that is copied from device to device from among a plurality of devices, some of which are parent devices and some of which are child devices, and wherein a child device may be registered with a parent device, including copying a digital work from a parent device, P1, to a child device, C1, registered with device P1, the digital work encapsulating digital rights management (DRM) data that serves to permit full access to the digital work by parent device P1, and to deny access to the digital work by devices other than device P1, modifying the DRM data in the copy of the digital work within device C1, so as to permit full access to the digital work, for a prescribed time period, by device C1 and by child devices other than device C1, inserting auxiliary DRM data in the copy of the digital work within device C1, so as to permit full access to the digital work by device C1, and so as to permit limited access to the digital work by child devices other than device C1, if the digital work is copied from device C1 to a parent device P2 other than device P1, then modifying the DRM data in the copy of the digital work within device P2, so as to permit limited access to the digital work by device P2, and removing the auxiliary DRM data in the copy of the digital work within device P2, and if the digital work is copied from device C1 to a child device C2 other than device C1, then modifying the auxiliary DRM data in the copy of the digital work within device C2, so as to permit limited access to the digital work by child device C2 and so as to permit limited access to the digital work by child devices other than device C2. A system and a computer-readable storage medium are also described and claimed.
