20090125718 | DOMAIN UPGRADE METHOD IN DIGITAL RIGHTS MANAGEMENT - Disclosed is domain upgrade method in Digital Rights Management (DRM) capable of reducing network resources by simplifying signal procedures at the time of transferring changed domain keys. A device joining after domain upgrade is provided with only a domain key of a domain generation after the domain upgrade, but is not provided with a domain key of the previous domain generation. Accordingly, even if the joining device is mal-operated or is hacked, contents before upgrade are prevented from being illegally used or leaking out. | 05-14-2009 |
20090209269 | SUPL INITIALIZATION MESSAGE IN A LOCATION INFORMATION SYSTEM AND METHOD AND SYSTEM FOR PROCESSING SUPL BY USING THE SAME - A terminal and method and system for processing SUPL are discussed. According to one embodiment, the invention provides a method of processing a SUPL request for a terminal that has performed roaming, the method comprising: receiving a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode; checking the indicator to determine whether a first message or a second message should be transmitted to the home SLP entity; and transmitting the first message or the second message to the home SLP entity according to a result of the checking step. | 08-20-2009 |
20090215467 | SUPL INITIALIZATION MESSAGE IN A LOCATION INFORMATION SYSTEM AND METHOD AND SYSTEM FOR PROCESSING SUPL BY USING THE SAME - A terminal and method and system for processing SUPL are discussed. According to one embodiment, the invention provides a method of processing a SUPL request for a terminal that has performed roaming, the method comprising: receiving a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode; checking the indicator to determine whether the home SLP operates in the proxy mode or the non-proxy mode; and selectively performing authentication with the home SLP entity based on the checking result indicating whether the home SLP entity operates in the proxy mode or the non-proxy mode. | 08-27-2009 |
20100191976 | METHOD FOR INSTALLING RIGHTS OBJECT FOR CONTENT IN MEMORY CARD - A method, device and system for stably issuing a rights object (RO) to a memory, namely, an SRM, via a terminal. When RO has been issued to the memory card, namely, to the SRM, by using the stable procedure, the RO can be compatible with a different terminal that does not support the stable procedure, whereby the RO can be completely used by the different terminal. | 07-29-2010 |
20100205439 | METHOD AND TERMINAL FOR RECEIVING RIGHTS OBJECT FOR CONTENT ON BEHALF OF MEMORY CARD - Disclosed is a method of receiving by a terminal a rights object (RO) from a rights issuer (RI) on behalf of a memory card, the method including, receiving, by the terminal, a trigger message for RO acquisition from the rights issuing server, comparing, by the terminal, trust anchor and ID of the memory card in a list included in the trigger message with a trust anchor and ID of the memory card within a context of the terminal, transmitting, by the terminal, a RO request message to the rights issuing server if the trust anchor and the ID of the memory card within the context are consistent with those within the list according to the comparison result, and receiving, by the terminal, a RO response message including a protected RO from the rights issuing server. | 08-12-2010 |
20120233466 | METHOD FOR INSTALLING RIGHTS OBJECT FOR CONTENT IN MEMORY CARD - A method of receiving, by a memory card, a rights object (RO) from a rights issuer (RI) via a terminal. The method includes: receiving from the terminal, a provisioning setup request message including information about a size of rights to be installed in the memory card; checking whether there is a space in the memory card for the rights; transmitting, to the terminal, a provisioning setup response message including a status indicating a result of processing the provisioning setup request message; and receiving, from the terminal, a rights provisioning request message for installing the rights into the memory card, the rights provisioning request message including rights information. The rights information is based on rights being extracted from a RO response message if a device identifier (ID) in the RO response message matches an ID of the memory card which is different from an ID of the terminal. | 09-13-2012 |
