Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a personal identification method for performing personal identification by means of an identification number (ID code) and a personal identification number (password).
In particular, it relates to the relief when the user forgets the personal identification number.

(Prior Art) In the case where cash is handled by an automated device, confidential information is handled, or a user is charged a usage fee,
It is necessary to confirm the user himself. Therefore, generally, an identification number (hereinafter referred to as an ID code) and a personal identification number (hereinafter referred to as a password) are registered, and the user inputs the ID code and password before using the device, and is registered. The procedure was to permit the use of the device if it matches the one in the above.

FIG. 3 is a functional block diagram showing a conventional personal identification method, and FIG. 4 is an operation flow chart thereof. In FIG. 3, 1 is a control unit for controlling the apparatus, 2 is an ID code input unit for inputting an ID code, 3 is a password input unit for inputting a password, 4 is a registered I
An ID code storage unit for storing a D code, 5 a password storage unit for storing a registered password, and 6 an ID code input from the ID code input unit 2 and an ID code storage unit 4 A collation unit for collating the ID code registered in 1) and a collation unit 7 for collating the password input from the password input unit 3 with the password registered in the password storage unit 5.

In the personal identification method by the device having the above-described function block, the ID code storage unit 4 and the password storage unit 5 are previously stored.
On the other hand, the ID code and the password are registered as a set. After that, when confirming the identity of the user,
First, the user inputs an ID code from the ID code input section 2 (step 101). The control unit 1 is the ID code input unit 2
At the same time as sending the ID code input from
The ID code registered in the code storage unit 4 is taken out and similarly sent to the collation unit 6. The collation unit 6 collates the ID code input from the ID code input 2 with the ID code retrieved from the ID code storage unit 4 (step 102).
If a match is obtained here, it is confirmed that the user has already been registered. Next, the user inputs the password from the password input unit 3 (step 103). The control unit 1 sends the password input from the password input unit 3 to the collation unit 7, and at the same time, sets the password registered in the password storage unit together with the ID code which has been confirmed by the collation unit 6 first. Is sent to the collation unit 7. The collation unit 7 collates the password input from the password input unit 3 with the password retrieved from the password storage unit 5 (step 104). If a match is obtained here as well, it is confirmed that the user is the user, and the identity verification procedure ends.

(Problems to be solved by the invention) However, in the personal identification method described above, if the user forgets the password, the password is newly registered and corrected. There is no other way than to be notified about it, and until then, there was a problem that the device could not be used temporarily.

It is an object of the present invention to provide a rescue procedure in the case where the user forgets the password in the above-described identity verification system for verifying the identity using the ID code and the password.

(Means for Solving Problems) The present invention provides a method for verifying an identity by sequentially comparing an ID code and a password sequentially input from an input unit with an ID code and a password registered in advance in a storage unit. Pertain.

In the present invention, a user-specific keyword associated with a password is registered in the storage unit in advance.

Then, after the ID code has been verified, when the input unit issues a keyword request instruction, the keywords registered in the storage unit are displayed.

(Operation) When confirming the identity of the user, the user inputs the ID code through the input unit. This ID code is collated with an ID code registered in the storage unit in advance. As a result of the verification, if the two match, the password input is awaited. Here, when the user forgets the password, the user gives a keyword request instruction through the input unit. Upon receiving this instruction, the keyword unique to the user is read from the storage unit and displayed. The user remembers the password by looking at the displayed keywords. Then, the user inputs the remembered password through the input unit. The entered password is collated with the password registered in the storage unit in advance. If the two match as a result of the collation, the identity verification ends.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention. In the figure, the same components as those in FIG. 3 are designated by the same reference numerals. Reference numeral 9 is a keyword storage unit. The keyword storage unit 9 is formed together with the ID code storage unit 4 and the password storage unit 5, for example, in the storage area of the magnetic drum. The keyword storage unit 9 stores a user-specific keyword associated with the password. Here, the memory of human beings can be remembered even if a forgotten person is given a word that is associated with it, that is, a keyword. Moreover, even if the same keyword is used, different people associate with each other, and it is difficult to know the password from other people's keywords.

Therefore, the user registers such a keyword in the keyword storage unit 9 in advance. This keyword is registered as a set with the ID code and password stored in the ID code storage unit 4 and the password storage unit 5, respectively.
Reference numeral 8 is a keyword request input unit. The keyword request input unit 8 is configured using, for example, one key having a keyword that constitutes the ID code input unit 2 and the password input unit 3, and is used when the user requests the display of the keyword. 10 is a keyword output section, which is a keyword storage section 9
The keywords read from are displayed. This display can be performed using a display normally provided in a device that requires identification. Reference numeral 11 denotes a control unit, which organically controls the above-mentioned constituent members.

Next, the operation of this embodiment will be described with reference to the operation flow chart shown in FIG.

When confirming the identity of the user, the ID code is first input from the ID code input unit 2 (step 201). Control unit 1
1 sends the ID code input from the ID code input unit 2 to the matching unit 6 and at the same time takes out the ID code registered in the ID code storage unit 4 and sends it to the matching unit 6 as well. The collation unit 6 collates the ID code input from the ID code input unit 2 with the ID code retrieved from the ID code storage unit 4 (step 202). If a match is obtained here, it is confirmed that the user has already been registered. Next, the user inputs the password from the password input section 3 (step
204). That is, in this case, it is unnecessary to refer to the keyword in step 203, and therefore the process proceeds to step 204. The control unit 1 sends the password input from the password input unit 3 to the matching unit 7, and at the same time, the matching unit 6 has previously confirmed the match I.
The password registered as a pair with the D code is taken out from the password storage unit 5 and is also sent to the collation unit 7. The collation unit 7 collates the password input from the password input unit 3 with the password retrieved from the password storage unit 5 (step 205). If a match is obtained here as well,
It is confirmed that the user is the registrant himself and the identity verification procedure ends.

However, if the user has forgotten the password, a keyword request is made from the keyword request input unit 8 after confirmation of the ID code (step 203). Control 11
Is a keyword registered from the keyword request input unit 8 (step 206), which is registered as a set with the ID code previously confirmed to match by the collation unit 6.
Extracted from the keyword storage unit 9 and output from the keyword output unit 10
To (step 207). The user can remember the password by looking at the keyword output to the keyword output unit 10, and inputs the password from the password input unit 3 (step 204). The subsequent password verification procedure is the same as that described above.

(Effects of the Invention) As described above, according to the present invention, in a device for identifying a user by using an ID code and a password, even if the password is forgotten, a keyword that will be a clue to remember the password is registered in advance. It is easy to remember the password by referring to the keyword. Therefore, a user who cannot use the device because he / she has forgotten the password can be relieved.
