摘要:
A method and system for generating a physical identifier in a storage device that includes a plurality of storage regions is provided. The method includes determining a number of reference storage regions for uniquely identifying the storage device; comparing the number of reference storage regions to a threshold; generating auxiliary storage regions for uniquely identifying the storage device, such that a number of the auxiliary storage regions corresponds to a result of the comparison; generating location distribution information of the reference storage regions and auxiliary storage regions; and storing the location distribution information in the storage device.

A method and a non-volatile memory apparatus for cloning prevention is provided. The non-volatile memory apparatus includes an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an EMID for identifying the non-volatile memory; and an EMID encoder for modifying the EMID by a preset operation in conjunction with an arbitrary value.
摘要:
An authentication apparatus includes a data storage unit for storing authentication apparatus identification information, an interface unit for connecting to a host device through a first interface, and an authentication processor that executes an authentication process using the authentication apparatus identification information stored in the data storage unit. The authentication processor executes the authentication process upon receipt of an authentication request signal from the host device through the interface unit, and outputs an authentication response signal including data indicative of a result of the authentication process to the host device via the interface unit. The authentication request signal is for requesting authentication of a data storage device connected to the host device through a second interface.

An authentication method of a storage device includes requesting an EID (Encoded IDentifer) to the storage device by an authentication device for authenticating the storage device, receiving the EID by the authentication device, restoring original ID information by decoding the received EID, and verifying individual ID information corresponding to use of the storage device included in ID information by using ID authentication information received from the storage device, wherein the ID information includes multiple pieces of individual ID information corresponding to the use of the storage device.
摘要:
Methods and apparatus are provided for providing a DRM service by a user terminal apparatus consuming DRM content in a service environment that provides the DRM content using a plurality of incompatible DRM systems. A license corresponding to the DRM content is acquired from a service providing apparatus that provides the DRM content. It is determined whether the license is a common license having a common DRM interface format. The common DRM interface format of the common license is converted to a format of a first DRM system installed in the user terminal apparatus, when the license is the common license. The license having the format of the first DRM system is applied in reproducing the DRM content. The common license is provided from the service providing apparatus to the user terminal apparatus through a common DRM interface when the service providing apparatus does not support the first DRM system.
摘要:
A storage device for protecting content, includes a Secure Area (SA) area in which a decryption key needed to decrypt encrypted content is stored, and access to which is available to a host device that has passed authentication using a secure authentication protocol. The storage device stores a security information file for mapping control information for controlling usage of the encrypted content and the decryption key to the encrypted content.
摘要:
A method is provided for controlling content playback by a terminal in a content delivery system. The method includes receiving streaming content from a service provider, the streaming content including zone information of each zone and an associated identifier of each zone for identifying a terminal's operation mode, determining the terminal's operation mode depending on the identifier, and controlling playback of the streaming content in a zone corresponding to the zone information according to the determined operation mode.
