Communication management system, communication management method and communication control device

A communication management system comprising:

• a terminal which has a peer to peer connection to communicate with a node conducting peer to peer communication;
• a content detector which detects identification information of a content of which distribution should be controlled, among contents that the terminal has received from the node, and registers the identification information in a content database;
• a communication control apparatus which refers to a database storing the identification information of the content detected by the content detector, so as to control the transmission of the content of which distribution should be controlled;
• and
• a database server which refers to the content database to update the database of the communication control apparatus,
• the content detector including:
• means for acquiring a content that the terminal has received from the node;
• means for determining if an acquired content is a virus-infected content and detecting identification information of a virus-infected content;
• means for accepting the designation of an inappropriate content from an operator who checks acquired contents to detect inappropriate contents, and detecting the identification information of the content;
• and
• means for registering the detected identification information in the content database,
• the communication control apparatus including:
• the database;
• a search circuit which acquires data of a content and searches the database for the identification information of the content;
• and
• a process execution circuit which performs processing for controlling the distribution of the content in accordance with the search result of the search circuit,
• wherein, when identification information of a content transmitted from the node to another apparatus matches identification information registered in the database in the peer to peer communication, the process execution circuit replaces the content with a warning content for warning that the distribution of the content should be restricted.

A communication management method, comprising:

• a content detector's acquiring a content that a terminal has received from a node conducting peer to peer communication, the terminal having a peer to peer connection to communicate with the node;
• a content detector's determining if an acquired content is a virus-infected content and detecting identification information of a virus-infected content;
• a content detector's accepting the designation of an inappropriate content from an operator who checks acquired contents to detect inappropriate contents, and detecting the identification information of the content;
• a content detector's registering detected identification information in a content database;
• a database server's referring to the content database to update a database of a communication control apparatus controlling the distribution of a content;
• a search circuit's acquiring data of a content and searching the database for the identification information of the content, the search circuit being provided in the communication control apparatus;
• and
• when in the peer to peer communication the node requested to search for a content transmits, to the request source of the search, a response including identification information of a content registered in the database, a process execution circuit's changing the address of a node distributing the content to the address of a warning content server which issues a warning that the distribution of the content should be restricted, the process execution circuit being provided in the communication control apparatus.

A communication control apparatus, comprising:

• a database which stores identification information of a content detected as a content of which distribution should be controlled, among contents transmitted between nodes through peer to peer communication;
• a search circuit which acquires data of a content and searches the database for identification information of the content;
• and
• a process execution circuit which performs processing for controlling the distribution of the content in accordance with the search result of the search circuit,
• wherein, when in the peer to peer communication the node requested to search for a content transmits, to the request source of the search, a response including identification information of a content registered in the database, the process execution circuit changes the address of a node distributing the content to the address of a warning content server which issues a warning that the distribution of the content should be restricted.
