METHOD AND TERMINAL OF VERIFYING MEMBERSHIP FOR MOVING RIGHTS OBJECT IN DOMAIN
First Claim
1. A method of verifying membership for moving Rights Object (RO) in a domain, the method performed by a first device comprising:
- sending an authentication request message from the first device to a second device;
receiving a authentication response message included verified value related the authentication request message; and
verifying whether the second device is a properly subscribed member of the domain by using the received authentication response message.

Abstract
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.

9. A method of verifying membership for moving Rights Object (RO) in a domain through a mutual verification process, the method comprising:
-
verifying, by a first device, whether a second device is a properly subscribed member of the domain by receiving an authentication request message, wherein the authentication request message includes a first verified value; and re-verifying, by the second device, whether the first device is a properly subscribed member of the domain by receiving an authentication response message in response to the authentication request message, wherein the authentication response message includes a second verified value. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

27. A method of checking membership for moving Rights Object (RO) in a domain, the method performed by a first device comprising:
-
sending, the first device to a first entity, a first request message for verifying whether a second device is a subscribed member of the domain; receiving, from the first entity, a first response message including a domain member verification result with respect to the second device; and checking the domain member verification result with respect to the second device. - View Dependent Claims (28, 29, 30)

31. A method of verifying membership for moving Rights Object (RO) in a domain, the method comprising:
-
extracting, by a second device, a verified value after receiving an authentication request message from a first device; and sending an authentication response message including the verified is value to the first device thereby allowing the first device for verifying whether the second device is a properly subscribed domain member. - View Dependent Claims (32)

33. A method of verifying membership for moving Rights Object (RO) in a domain, the method comprising:
-
receiving, by a second device, an authentication request message including a first verified value calculated by a first device so as to verify whether the first device is a properly subscribed domain member; calculating, by the second device, a second verified value using a domain key; and sending, by the second device, an authentication response message including the second verified value to the first device such that the first device verifies whether the second device is a properly subscribed domain member. - View Dependent Claims (34, 35)

-
a first entity adapted to manage a domain registration and a domain subscription; a second entity adapted to issue a domain key and a domain Right Object (RO) and to provide a content; a first device adapted to receive the domain key, the domain RO and the content from the second entity, wherein the first device is registered and subscribed via the first entity; and a second device adapted to receive the domain RO and the content from the first device if the second device is verified as a properly subscribed domain member by the first device. - View Dependent Claims (37, 38, 39, 40, 41)
