PROBLEM TO BE SOLVED: To more simplify the procedure of user authentication to be performed by one user with respect to a plurality of information processing terminals. SOLUTION: When each user inputs user ID as identification information assigned to himself or herself and a password which only the user knows to any display device of display devices 10a to 10f to log-in, the user becomes able to use the display device. Furthermore, when the display device to which the user ID and the password have been input makes a request for log-in to the other device, the user can use the display device whose use has been registered beforehand about the user. Thus, it is possible for the user to use the plurality of display devices only by one time user authentication, it is therefore possible to reduce workloads for the user authentication in comparison with a case where the user authentication operation is performed on each of the plurality of display devices.
