<p>PROBLEM TO BE SOLVED: To realize pairing among terminals without requiring any special module at terminals and imposing increased burdens on users.SOLUTION: A first terminal 10A and a second terminal 10B respectively have display units 11A and 11B and imaging units 12A and 12B, and each display unit displays images shot by each imaging unit as display images. An authentication server 20 compares two display images received from the two terminals and, if it determines that the two display images have resulted from shooting of the display unit 11B of the second terminal 10B by the imaging unit 12A of the first terminal 10A and simultaneous shooting of the display unit 11A of the first terminal 10A by the imaging unit 12B of the second terminal 10B, namely from mutual shooting by the two terminals 10A and 10B arranged in positions of mutually facing two mirrors, determines that they are to be objects of pairing.</p> |
