<p>PURPOSE:To improve the secrecy to the illicit users by attaining a constitution where an aural questioning means shows whether a user input a right identification No or not by reference to a rejection memory after the aural questions. CONSTITUTION:The information on the illicit use is not sent to an aural question control pat 31 and stored once in a rejection memory 34. The part 31 orders a question generating part 1 to produce all aural questions, and a final deciding part 35 checks whether the information on the illicit use is written in the memory 34 or not to inform the part 31 of this check result. At this time point, a treatment is applied for the first time to the illicit use, i.g., 'Your identification No is wrong.' is produced in voices. Thus the illicit use is treated after all questions are through for confirmation of an identification No. Thus it is possible to eliminate such an inconvenient case where an illicit user guesses the identification No.</p> |
