JPS59201142A - Leakage preventing system for identification number using voice input - Google Patents

Abstract

PURPOSE:To keep the secrecy of identification number by providing a means to inform the use of the unspecified numerical value to a user when the user feeds the identification number, and then supplying the arithmetic result numerical value obtained from the identification number registered previously. CONSTITUTION:When a user connects a telephone 10 to a center 9, the center 9 first informs the confirmation of identification to the user and at the same time produces the numerical value having the same number of digits as the identification number through a random number generator 7. Then the center 9 informs the user to feed the generated numerical value after adding it to the numerical value having corresponding digits. Thus the user feeds the added numeric characters in voice, and these numeric characters are sent to a voice recognizing part 4 through a switching part 2 for analysis and decision. This numerical value is subtracted at a control part 6 by the numerical value of digits corresponding to the numerical value generated previously from the generator 7 and informed to the user. This subtracted numerical value is sent to a host computer, and the host computer performs the recognition with the numerical value obtained with addition/subtraction of random numbers. In sach a way, the secrecy of an identification number is kept.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a system for preventing an identification number for checking user qualifications from being leaked to others during input in a system that performs a small input by voice. .

(2) Prior art and problems In information processing systems used by multiple users,
In order to prevent the destruction or unauthorized use of programs and data due to mistake or intent, an identification number (also called a code number) agreed upon in advance with the user must be registered.
Many systems employ a system in which when a user inputs the identification number prior to use, it is registered and checked against a certain identification number to determine whether or not the user is eligible for use.

The voice input system has the disadvantage that when entering such an identification number, the number can be heard naturally if there are people around, so it is impossible to maintain confidentiality.

(3) Purpose of the Invention In view of the above-mentioned shortcomings of the conventional art, the object of the present invention is to provide a method that can maintain confidentiality even if a stranger who is around hears the input when an identification number is input by voice. It is said that

(4) Structure of the invention and this purpose according to the present invention is as described in the claims. In an information processing system that checks usage qualifications, a means is provided to notify the user of an unspecified numerical value each time the user attempts to input an identification number, and the user can combine the numerical value with the previously registered identification number. This is achieved by a formula for preventing leakage of the identification number by voice input, which is characterized by inputting the numerical value of the calculation result as the identification number.

(5) Embodiment of the invention FIG. 1 is a block diagram showing an embodiment of the invention,
1 is a line control unit, 2 is a switching unit, 3 is a speech synthesis unit, 4 is a speech recognition unit, 5 is a recognition dictionary file, 6 is a control unit, 7 is a random number generator, 8 is a connection terminal with the host computer, 9 represents a center, 10 represents a telephone, and ++ld communication line.

In this embodiment, the user uses the system by inputting voice from a telephone, and notifications from the center to the user are also sent via the telephone of the synthesized voice stain removal machine.

In Figure 1, a user dials τ from a telephone 1o.
When connected to center 9, 1. Upon receiving this, the center side first synthesizes a message to the effect of confirming the identification number and sends it to the communication line 11 according to instructions from the host computer, and notifies the user. Then, the random number generator 7 generates a numerical value with the same number of digits as the identification number, and for each numerical digit, a message is attached to the user asking the user to add the numerical value to the numerical value e in the corresponding digit of the identification number and input it. Then, synthesize the voice and output it. In response to these messages from the center, the user inputs the corresponding numbers one after another by voice. The voice input from the user is sent to the voice recognition section 4 by the switching section 2, where it is analyzed and the input numerical value is determined. The control unit 6 subtracts the numerical value corresponding to the numerical value previously generated by the random number generator 7 and notified to the user, and sends the result to the host computer. The host 9 viewer checks the numerical value reproduced in this manner against the registered identification number to check whether the usage qualification has been renewed.

FIG. 2 is a diagram showing an example of a user's voice input and a voice output from the center. Figure 2 shows the case where the identification number is 4321 and the number generated by the random number generator is 3981. Also, when inputting, the number notified from the center is added for each digit of the identification number each time. The result is 10
If the number exceeds that number, it is agreed that only the lower 1 digit will be entered. Note that the expression beep in the figure represents a signal tone.

To explain based on Figure 2, when a user connects to the center by dialing a telephone, the center will send a voice message saying ``We will confirm your identification number.'' Please, please, please.'' I was sent the rice.

The user adds 5 to the first digit of the identification number, 4, and enters ``
7". Next, the center sends a message saying, ``Please add 9 to the next number,'' so enter ``2,'' which is the last digit of 12, which is 3 plus 9. In this way, when you enter numbers one after another and reach 4 digits, you will receive a message from the center saying ``Your identification number is 4.
321,” and if it is correct, you can respond with “Yes.”

(6) Detailed Description of the Invention According to the present invention, when inputting a number such as an identification number that the user does not want others to know by voice, the user can add the numerical value sent from the center, etc. The confidentiality of the identification number is maintained because the number is entered as a completely different number from the original identification number, and the center notifies you of a different number each time, so you enter a different number each time. It is possible and effective for dogs.

Claims (1)

[Claims] In an information processing system that checks the usage qualifications of a user by comparing the identification number entered by the user with a pre-registered identification number, an unspecified value is generated each time the user attempts to enter the identification number. A means for notifying a user of a numerical value is provided, and the user inputs, as the identification number, a numerical value that is the result of calculating the numerical value and an identification number registered in advance.The ability to prevent leakage of an identification number by voice input. formula.
