Communication management system, communication management terminal device, communication management method and communication management program

A non-transitory computer readable recording medium storing a program for a communication terminal device which performs talks and communications via a communication network, the program causing a computer to execute:

• a function which manages history information of the talks and communications as a database by each partner user of the talks and communications;
• a function which manages a reliability rule as a basis for judging a reliability relationship of the talks and communications as a database;
• a function which judges whether or not the partner user is reliable enough based on the history information of the talks and communications stored by each of the partner users of the talks and communications and the reliability rule, and generates a list with a valid time limit;
• a function which stores the list, and provides the list in response to an inquiry that is made when performing the talk and communication with the partner user;
• and
• a function which searches the list, and controls the talks and communications by judging reliability of the partner user based on a searched result.

A management method of a communication terminal device which performs talks and communications via a communication network, the method comprising:

• managing history information of the talks and communications by each talk and communication partner user;
• managing a reliability rule that is a basis for judging a reliability relationship of the talks and communications;
• judging whether or not the partner user is reliable enough based on the history information of the talks and communications stored by each partner user of the talks and communications and the reliability rule, and generating a list with a valid time limit;
• storing the list, and providing the list in response to an inquiry that is made when performing the talk and communication with the partner user;
• and
• searching the list, judging reliability of the partner user based on a search result thereof, and controlling the talk and communication.

Communication terminal means for performing talks and communications via a communication network, the terminal means comprising:

• communication history information memory means for storing history information of the talks and communications by each talk and communication partner user;
• condition information memory means for storing a reliability rule that is a basis for judging a reliability relationship of the talks and communications;
• communication admissible list generating means for judging whether or not the partner user is reliable enough based on the history information of the talks and communications stored in the communication history information memory means by each partner user of the talks and communications and the reliability rule stored in the condition information memory means, and generating a list with a valid time limit;
• communication admissible list memory means for storing the list generated by the communication admissible list generating means, and providing the list in response to an inquiry that is made when performing the talk and communication with the partner user;
• and
• communication means for making an access to the communication admissible list memory means to search the list of a partner user with which a talk and a communication is to be performed, judging reliability of the partner user based on a search result thereof, and controlling the talk and communication.
