Communication terminal identification information identifying processing system

A communication terminal identification information identifying processing program stored on a memory, for causing a computer used in a communication terminal identification information identifying processing system for identifying communication terminal identification information of a user who performs communication with a portable communication terminal using a wireless communication device to function as:

• a person recognition processing unit configured to perform recognition processing as to whether a person appears, based on image information obtained by capturing a wireless LAN communication spot where the wireless communication device exists by a capturing device wherein the person recognition processing unit determines whether the person is a person having appeared in the past by comparing the image information with information of persons recognized in the past;
• a communication terminal identification information acquisition processing unit configured to acquire communication terminal identification information of the portable communication terminal that performs communication using the wireless communication device;
• a communication terminal identification information comparison processing unit configured to compare, for each person recognized in the person recognition processing unit, candidate communication terminal identification information of the portable communication terminal of the person recognized in the person recognition processing unit, the candidate communication terminal identification information being stored in a communication terminal identification information storage unit that stores the candidate communication terminal identification information of the portable communication terminal used by the person, and the communication terminal identification information acquired in the communication terminal identification information acquisition processing unit, and generate new candidate communication terminal identification information;
• an output processing unit configured to output a part or all of the candidate communication terminal identification information stored in the communication terminal identification information storage unit as the communication terminal identification information used by the recognized person;
• and
• a management unit configured to manage access to communication between the portable communication terminal used by the person and the wireless LAN communication spot where the portable communication terminal exists based on the output of the output processing unit prior to input of user identifying information by the portable communication terminal, wherein the output of the output processing unit is based at least in part on an image recognition data, the image recognition data comprising at least image information of a face portion of the person captured by the capturing device, and wherein the image recognition data is utilized by the person recognition processing unit to perform the recognition processing as to whether the person appears.
