摘要： During the performance of a printing command of an application program of a client being connected to a server, the printer status information is provided to the client so that the client can selectively use a variety of printer features. Additionally, printers are effectively managed and controlled so that a printing system has an improved operation speed. The printing system is controlled at a management server. In the printing system having the server, at least one client, and a plurality of printers, each being connected through a communication line, the server has the printer status information. Accordingly, in the performance of a printing command of the client, the client requests the management server for the transmission of the printer status information, receives the requested information, and indicates the received information through an indicating part according to a predetermined form.

摘要： Provided are an apparatus and method for managing digital rights. An agent unit manages application programs to which DRM is to be applied and rights to contents processed by the application programs to which DRM is to be applied, and encrypt and decrypt the contents processed by the application programs. A rights management unit authenticates a user and manages a user right to the contents processed by the application programs. A kernel API hooking unit monitors input/output of a file through hooking kernel native APIs, requests the rights management unit to verify the user right to the contents to be processed, and requests the agent unit to encrypt or decrypt the contents when the user right to the contents to be processed is verified.

摘要： Provided are apparatus and method for selectively decrypting and transmitting DRM contents. A policy storing unit stores information on devices allowed for decryption of contents. A policy processing unit determines whether a target device, to which an encrypted content is transmitted, is a device allowed for decryption based on the information stored in the policy storing unit. A decryption unit decrypts the encrypted content. And a control unit controls the decryption unit to decrypt the encrypted content when the target device is the device allowed for decryption.
