PURPOSE:To provide a user discriminating device which automates an manual process for account input, etc., while maintaining system security. CONSTITUTION:The user discriminating device which discriminates a user who is allowed to use an object device is provided with a transmitting means 11 which sends a signal wave consisting of a combination of plural frequency components, a receiving means 2 which receives the signal wave, an analyzing means 3 which digitizes the frequency spectrum of the received signal wave, and a decision means 5 which compares the value digitized by the analyzing means 2 with a registered value and outputs a control signal to the object device 7 when they match each other. On the basis of the combination of frequencies of the signal wave that the user sends, it is decided whether or not the user is a system registered user and when it is decided that the user is the regular user, an interruption signal is automatically outputted to the object device 7 to perform a log-in process, etc. |
