TERMINAL DEVICE, SERVER DEVICE, IDENTITY ASSESSMENT SYSTEM, IDENTITY ASSESSMENT METHOD, AND PROGRAM

摘要

Provided are terminal devices (12–n) which are connected via a network (11) to a server device (10) which stores voices of purchasers of tickets. Said terminal devices (12–n) comprise a voice input unit (201) which receives an input of a voice, and a control unit (205). In response to the voice of a bearer of the ticket having been inputted into the voice input unit (201), the control unit (205) acquires via the network (11) the voice of the purchaser of the ticket which is stored upon the server device (10). The control unit (205) compares the voiceprint of the bearer of the ticket with the voiceprint of the purchaser of the ticket and assesses whether the identity of the bearer of the ticket is the same as the identity of the purchaser of the ticket. If it is assessed that the identity of the bearer of the ticket is the same as the identity of the purchaser of the ticket, the control unit (205) assigns a usable state to the ticket.
