METHOD FOR DETERMINING AND RENEWING WHETHER A DRM CLIENT BASED ON AN INTERACTIVE SERVICE IS DUPLICATED IN ORDER TO RESTRICT THE USE OF THE DRM CLIENT OF A TRUST HOST WHICH USES A DUPLICATED DRM CLIENT

摘要

PURPOSE: A method for determining and renewing whether a DRM client based on an interactive service is duplicated is provided to compare synchronized clone information and determine whether the DRM client is duplicated. ;CONSTITUTION: In case a Trust host(230) is booted, the Trust host receives the version information of a DRM(Digital Rights Management) client(233) from a Renewability server(220). The Trust host compares the received version information of the DRM client and the version information of the DRM client stored in the Trust host. The Trust host loads stored clone information and transmits the clone information to the Renewability server. The Trust host compares clone information received from the Renewability server and clone information stored in the Renewability server.;COPYRIGHT KIPO 2011
