Abstract
A method of using digital rights management (DRM) content while roaming is provided. The method includes issuing disposable authentication information to a mobile device; receiving a request for remote authentication along with the authentication information from an unauthorized device included in a remote domain; transmitting a query for the remote authentication to the unauthorized device; receiving a response to the query; and transmitting data approving authentication of the unauthorized device to the unauthorized device.
Claims18
A method of using Digital Rights Management (DRM) content while roaming, the method comprising:
- issuing disposable authentication information to a mobile device;
- receiving a request for remote authentication along with the authentication information from an unauthorized device included in a remote domain;
- transmitting a query for the remote authentication to the unauthorized device;
- receiving a response to the query;
- and
- transmitting data approving authentication of the unauthorized device to the unauthorized device.
A method of using Digital Rights Management (DRM) content while roaming, the method comprising:
- issuing disposable authentication information from a device of a source domain to a mobile device;
- requesting remote authentication to an unauthorized device of a remote domain using the disposable authentication information;
- receiving a result approving remote authentication from the unauthorized device;
- and
- transmitting a temporary rights object to the unauthorized device.
A method of using Digital Rights Management (DRM) content while roaming, the method comprising:
- receiving a message requesting remote authentication from a mobile device;
- transmitting a remote-authentication request message, which comprises a device identifier of a source domain expressed in the message, to a device of a remote domain;
- receiving a query for remote authentication from the device of the remote domain;
- transmitting a response to the query to the device of the remote domain;
- and
- receiving data approving authentication from the device of the remote domain.
A method of using Digital Rights Management (DRM) content while roaming, the method comprising:
- receiving a message requesting remote authentication from an unauthorized device;
- sending a request for remote authentication to a first device of a source domain expressed in the message, and receiving a query for remote authentication from a second device of a remote domain;
- transmitting the query to the unauthorized device, and receiving a response to the query from the unauthorized device;
- transmitting the response to the first device of the source domain;
- and
- receiving data approving authentication from the first device of the source domain, and transmitting the authentication-approving data to the unauthorized device.
A device comprising:
- an authentication unit which issues disposable authentication information to a mobile device,
- a receiving unit which receives a request for remote authentication along with the authentication information from an unauthorized device included in a remote domain;
- a transmitting unit which transmits a query for authentication to the unauthorized device;
- and
- an encoding or decoding unit which encodes or decodes data transmitted and received via the transmitting unit or the receiving unit,
- wherein the receiving unit receives a response to the query from the unauthorized device, and the transmitting unit transmits data approving authentication of the unauthorized device to the unauthorized device.
