METHOD AND TERMINAL OF VERIFYING MEMBERSHIP FOR MOVING RIGHTS OBJECT IN DOMAIN

摘要

Disclosed is a Digital rights Management (DRM), and particularly a method and terminal for verifying membership in order to move Rights Object (RO) in a domain, the method implemented in a first embodiment in which a second device calculates a MAC value as a verified value to send to a first device before the first device moves a domain RO to the second device, and accordingly the first device verifies that the second device is a properly subscribed domain member to thereafter move the domain RO, and a second embodiment in which when the first device calculates a first verified value to send to a second device, the second device verifies whether the first device is a properly subscribed domain member and then calculates a second verified value to send to the first device, and the first device also verifies whether the second device is a properly subscribed domain member to thereafter send the domain RO to the second device. The present invention allows the domain RO to be moved in the domain only between devices which properly belong to the domain, such that a problem in security, which may occur when moving the domain RO without verifying whether a device to receive the domain RO moved is the properly subscribed domain member upon the movement of the domain RO between the devices, can be avoided.
