Apparatus and method for managing digital contents distributed over network

摘要

A content management system entails analyzing similarity of the contents distributed among at least one network element (e.g., contents server) and managing the contents on the basis of the analysis result. The content management server analyzing similarities of content files and providing the similarities information includes a communication unit that collects content information from at least one content server stored the content files and the content information corresponding to the content files; a digital content management (DCM) control unit which analyzes similarities of the content files received from the content server; a storage which stores information on the similarities analyzed by the DCM control unit; a content information comparison unit which detects the content information in response to a similar content file request transmitted from a client on the basis of the similarities information.

1. A content management server which analyzes similarities of content files distributed over a network and provides similarities information, comprising:
a communication unit which collects content information from at least one content server storing the content files and the content information corresponding to the content files; a digital content management (DCM) control unit which analyzes similarities of the content files received from the content server; a DCM storage unit which is locally coupled to the DCM control unit and stores information on the similarities of the content files analyzed by the DCM control unit; and a content information comparison unit which detects the content information in response to a similar content file request transmitted from a client on the basis of the similarities information of the content files; wherein when content information stored in the DCM storage unit and analyzed by the DCM control unit differs from received content information from said at least one content server, the content information comparison unit requesting a particular content file corresponding to the received content information from the at least one content server accessed over a network through the communication unit to update the content information in the DCM storage unit to match identically with the content information received from the content server after updating the content information in the storage unit.
