    摘要: A tool pack structure includes: a signature value for guaranteeing authenticity of a tool pack; a tool pack identifier for identifying the tool pack; each unit tool pack provided according to a hardware platform; and tool pack data containing initial values assigned when each unit tool pack is used. Each tool pack includes platform information indicating information about hardware in which the tool pack may be used; a tool agent that is a program activated for content execution; and a tool group including at least one tool program activated by the tool pack agent for processing content according to a predetermined rule. A tool agent leaves operation of a protection tool group used by a specific service provider entirely to a tool agent (execution code) provided together with the tool group by service providers. Accordingly, information about the used tools does not have to be disclosed to the public. Since a user terminal simply calls each tool agent, it can support interoperability with other DRM techniques.

    摘要: Provided are domain contexts indicating user and device based domain systems for being applied to a new digital content protection/management system, and management methods thereof. A concept of “domain” is introduced in the present invention so that various business models can be obtained in accordance with content use of one home or small-sized group. The domain refers to as a group of user and device SAV and PAV indicating a context for being applied to the domain system includes: a domain identifier for specifying a domain as a region containing at least one content execution device and at least one content user; domain authentication information for guaranteeing authenticity of the domain; a user list containing information of users belonging to the domain; and a device list containing devices belonging to the domain.

    摘要: A license data structure and distribution (issuance) method are provided, that can accommodate one domain including multiple content playback devices and/or users. A method for creating license data in the invention includes the steps of: creating raw license data to be issued; firstly encrypting the raw license data with an encryption key of a user and/or device; and encrypting the data encrypted with the user and/or device public key using a public key of a home domain. Also, a license data structure of the invention includes an encrypted license block created by firstly encrypting raw license data containing data for playing content with a distributed encryption key of a user and/or device, and then secondly encrypting this with a distributed encryption key of a home domain; and TAG information necessary for decryption of a second encryption capsule.

    摘要: The present invention relates to a language representation method and data structure for updating an IPMP tool, a method for updating an IPMP tool using the same and a client apparatus using the same in protection and management of multimedia contents, by which the IPMP tool can be represented dynamically in order to provide convenience to users. In the language representation method for updating an IPMP tool in an MPEG-21 multimedia framework, an update element, which describes update information of the IPMP tool, is defined as a higher level element; and a location element, which has information on a location allowing the IPMP tool to be carried thereto, is described as a lower level element of the update element.
