摘要

PROBLEM TO BE SOLVED: To provide an identification server device by which identification is possible by simple operation without allowing a user to input a password etc. SOLUTION: An identification picture data generation part 32 generates identification picture data in connection with client device identification information received by a network connection part 31, and registers it in an identification data storage part 33. A client device identification part 34 collates identification picture received by the network connection part 31 with the identification picture data stored in the part 33 and identifies it. Consequently, the user can perform identification only by inputting the identification picture and transmitting it to the identification server device 2.
