Abstract

PURPOSE:To protect a password number from the 3rd party even when an input device which the 3rd party can easily understand by rendering a user to convert his password number to the other number according to the indication of a system and inputting the converted number through a pushbutton telephone set, etc. CONSTITUTION:When incoming from user's key telephone set 1 is present, an audio response system 7 indicates converting the password number from an audio response unit 3. When the indication of a new password number 4361 is issued with respect to a password number 1984, for instance, the user adds the figure indicated from the audio response unit 3 and the one having the order corresponding to the original password number, and forms the new password number by taking only the 1st order, and inputs it through the key telephone set 1. The inputted password number is received by a key signal receiver 4. A central control unit 5 converts reversely the newly obtained password number into its original, which is collated with the password number that corresponds to the user and is stored in a memory device 6. Finally whether services required by the user is accepted or not is decided.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method in which a user inputs recitation information such as a recitation number from a terminal such as an online system, and particularly relates to a system in which a user inputs recitation information such as a recitation number from a terminal such as an online system. It relates to an input method suitable for

[Background of the idea]

The conventional recitation number input method is, for example,
As shown in Publication No. 8, I was inputting a slightly delayed keystroke @CN number).

Although this method allows the user to easily input the code number, the user can press which button the user presses in a way that can be easily concealed by a third party nearby, thus keeping the number secret from the third party. [Objective of the Invention] The purpose of the present invention is to provide an input method that allows a third party to easily understand which input key the user presses on a push-button telephone or the like when inputting a code number. To provide a system in which a recitation number can be kept secret from a third party even when @pupil is used.

[Summary of the invention]

In the present invention, as a method for the user to input the PIN number, the user converts the PIN number to another number according to instructions from the system, and then inputs the converted number by pressing the button ``#L''. A method of inputting by Iso et al. is adopted.Since the instructions from the system change for each call, it is impossible for a third party to estimate the original recited number from the altered recited number.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Figure 1 shows that the user's pushbutton 1 is connected to the telephone exchange network in order to receive services such as checking the balance of a bankbook.
shows a state connected to the voice response system 7 via
The voice response system 7 uses a user's pushbutton IIL.
When there is an incoming call from r1s 1, the voice response device 3
As shown in FIG. 2, an instruction to convert the chord code is issued. *2 The example shown in FIG. First, the voice response device [3]
)'' is sent to the user, and the user inputs 5, which is the 10,000's digit of the recited number, by adding this 4 to the 10,000's digit of the new recited number, using the push button 'a' on the phone.
Similarly, for the thousands digit, hundreds digit, and - digit, add the numbers instructed from the voice response device 3 and the corresponding digits of the original recited number, and take only the first digit. Then, input the new recitation number from pushbutton 1.
1, that is, in this case, when the secret number conversion finger is sent to the 1-digit user, the converted recitation number is sent from the user to the 1-digit push button signal receiver 4.

Note that the numbers in this conversion instruction are changed randomly each time. In addition, in the above example, the conversion instruction was addition for each digit of the recited number, but subtraction, multiplication, division, etc. can also be considered, and the cells do not correspond to each digit, but all digits are treated as one number. There are also ways to handle the above conversion instruction data, which is created by the central control unit [5] and sent to the voice response unit lt5,
5, it is also used to convert the recitation number input by the user from the push button signal receiver 4 back into the original recitation number. This inversely converted recitation number is stored in the Bereturn device 6. The user's password is compared with the user's password, and it is determined whether or not to accept the service requested by the user.

In the above example, the 111t recited name is used, but it is also possible to use memorized information such as the Japanese syllabary or the alphabet. If the user inputs the 11f recitation code from Kosue, where the 3rd ministries around 11 can easily understand the input numbers, the effect is that the user can input the real recited number secretly from the 3rd@. There is

Claims (1)

[Claims] 1. In a system that compares the recitation information input by the user with recitation information previously stored in the system and decides whether to accept or reject a service request from the user, the system sends an instruction to convert the recitation information to the user, and according to the instruction Recitation information characterized by receiving recitation information converted by a user, and comparing a number that is inversely converted to make the recitation information into the original recitation information and recitation information stored in the system in advance. method.
