    摘要: A method and apparatus for managing digital content are provided. The apparatus for managing digital content generated by applying digital rights management (DRM) includes: a content execution unit executing digital content; and a control unit confirming whether or not digital content is in a first period in which the digital content can be normally executed, and controlling the content execution unit so that, if the digital content is in the first period, the digital content can be executed normally, and if the digital content is in a second period which is not in the first period, the digital content can be executed in a manner which can be distinguished from that of execution in the first period. According to the apparatus and method, execution of digital content, which is close to expiration, can be controlled, thereby managing the expiration of the digital content for a user.

    摘要: A method and apparatus for providing digital rights management (DRM) content and a license, and a method and apparatus for using DRM content are provided. The method of providing DRM content and a license includes selecting usage conditions for content; transforming the usage conditions into a secure database (DB); and adding the secure DB to a license. The method of using DRM content generated by applying DRM includes searching for a license corresponding to the DRM content; authenticating a user who wants to use the DRM content; extracting usage conditions included in the license by using a secure DB agent, and confirming whether or not an action desired to be performed by the user satisfies the usage conditions; and if the action desired to be performed by the user satisfies the usage conditions, using the DRM content according to the action.
