JPS63207262A - Personal identification number protecting system - Google Patents

Abstract

PURPOSE:To prevent a personal identification number from being leaked to a person even if he exists by a telephone set, by providing an audio response recognizing device which instructs the insertion of dummy numbers at random to the personal identification number inputted with a voice from a subscriber. CONSTITUTION:When message 'Please, input the personal identification number.' is outputted from an audio response recognizing device 10, a subscriber 20 hears a blip to successively input the personal identification number '1, 2, 3, 4' with voice, but a message to require the input of dummy numbers '6' and '8' is outputted besides blips during the input of the personal identification number. The subscriber 20 inputs the personal identification number and dummy numbers with voice in accordance with messages. The audio response recogniz ing device 10 inserts dummy numbers '6' and '8' to the actual personal identifi cation number '1, 2, 3, 4' at random by the application of software at the time of inputting the personal identification number. Thus, the correct personal identification is prevented from being leaked to the others.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for protecting a password input by voice.

[Conventional technology]

Conventionally, no security protection measures have been taken when entering a personal identification number by voice in a voice inquiry notification service provided by a bank or the like. In other words, as shown in FIG. 2, when the voice response recognition device 10 outputs the message "Password please", the subscriber 20 hears a "beep" and audibly inputs the password rl, 2, 2, Input 3 and 4J sequentially.

[Problem that the invention seeks to solve]

In the voice inquiry notification service described above, no measures are taken to protect the secrecy of the PIN number, so if there is a person next to the telephone, the PIN number will inevitably be leaked.

[Means for solving problems]

The password protection system of the present invention is characterized by comprising a voice response recognition device that instructs to randomly insert a dummy number into the password input by voice from the subscriber.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, which shows one embodiment, when the voice response recognition device 10 outputs the message "Please enter your PIN," the subscriber 20 hears a "beep" and audibly inputs the PIN r1. .2, 3, 4" in sequence, but while entering the PIN, in addition to the "beep" sound, the dummy numbers r6, 8... A message will be output requesting input. The subscriber 20 inputs a personal identification number and a dummy number by voice in accordance with each message. The voice response recognition device 10 uses a software application to recognize the actual password rl when inputting the password.
, 2, 3, 4. A dummy number "6°8" is randomly inserted between the two. This prevents the correct password from being known to others. Note that the dummy number inserted between the password numbers and the insertion location thereof are completely random.

Furthermore, the numerical value of the dummy number and its insertion point are changed for each service.

〔Effect of the invention〕

As explained above, according to the present invention, it is not known which number is a dummy number unless the voice from the handset is heard while inputting the PIN number, so even if someone else memorizes the number spoken by the subscriber, the number cannot be used. In other words, even if someone other than the subscriber memorizes the number uttered by the subscriber and attempts to enter it, the numerical value of the dummy number and its insertion position have already been changed, so they will not know which is the correct PIN number and will not be able to enter the PIN number. Confidentiality can be maintained.
