JPH064535A - Id discriminating device - Google Patents

Abstract

PURPOSE:To provide an ID discriminating device which can improve the security by deciding a password number with use of an element that momentarily changes and is not easily known by the outsiders and by avoiding the use of a fixed password number when the ID is discriminated with collation of the password numbers inputted by the ten keys. CONSTITUTION:A calendar date of 4 digits, e.g. 'April 30' (0430) is added to a 4-digit personal password number '4586'. Thus, a new 8-digit password number '45860430' is obtained. When an password number is inputted by the ten keys (S1), the collation is carried out to decide whether the first 4 digits of the input number are coincident or not with a personal password number stored in a ROM (S2). If not, an 'NG' lamp is temporarily turned on (S3). If so, the collation is carried out to decide whether the subsequent 4 digits of the number are coincident or not with the date of today (S4). If not, the flicker lighting of the NG lamp is controlled (S5). If so, the 'OK' output is transmitted and at the same time an 'OK' lamp is temporarily turned on.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ID discriminating apparatus for discriminating an ID based on collation of a personal identification number input by a ten-key pad.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Unexamined Patent Publication No. Hei 2-16249.
As shown in Japanese Patent No. 6, set a personal identification number for each individual,
2. Description of the Related Art There is a crime prevention system that prevents illegal intruders by comparing IDs when entering or leaving a predetermined room in a building to determine an ID.
The security system disclosed in the above publication uses a personal identification number as an ID.
The card is written and read at the time of entering / leaving the room for verification, but it may be replaced by inputting a personal identification number using a ten-key pad and performing verification to determine an ID.

[0003]

However, in the ID discriminating apparatus for discriminating the ID based on the collation of the personal identification number input by the ten-key pad, the personal personal identification number usually used is a short number of about 4 digits which is not forgotten. In many cases, the secret code was fixed and did not change, so it was often used by others.

The present invention has been made in order to solve the above-mentioned problems of the conventional example, and it is not a fixed personal identification number itself, it is difficult for others to understand, and a personal identification number is incorporated by incorporating an element that changes from moment to moment. An object of the present invention is to obtain an ID discrimination device capable of improving the property.

[0005]

SUMMARY OF THE INVENTION An ID discriminating apparatus according to the present invention is an ID discriminating apparatus for discriminating an ID based on collation of a personal identification number input by a ten-key pad, and at least a part of a calendar is used for a personal personal identification number. It is provided with a discriminating means for discriminating the ID as the ID discriminating condition that the number thus obtained is used as a new personal identification number by the ten keys.

[0006]

In the present invention, the discriminating means for discriminating the ID is
A personal identification number obtained by using at least a part of the calendar is discriminated as a new personal identification number. Since the personal identification number itself changes, it is not used for others.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of an ID discrimination device 1 according to this embodiment. In the figure, reference numeral 1 is an ID discrimination device, on the surface of which a numeric keypad 2 for inputting a personal identification number, an OK lamp 3 and an NG lamp 4 for displaying an ID discrimination result by numeric input by the numeric keypad 2 are provided. There is.

FIG. 2 shows a specific internal structure of the ID discriminating apparatus 1. Inside the ID discriminating apparatus 1, in addition to the numeric keypad 2, the OK lamp 3 and the NG lamp 4, a CPU 1a,
ROM storing processing programs and fixed data
1b, RA for temporarily storing processing data, input data, etc.
M1c, digital type fountain clock 1d with a calendar function that automatically calculates leap years, and O when the ID discrimination result is OK
An interface 1e is provided for sending out the K output (non-voltage a contact).

Next, the operation of the above configuration will be described with reference to FIG. FIG. 3 shows the CP stored in the ROM 1b.
It shows the flowchart which operates based on the control of U1a. First, in this embodiment, for example, in the case where the personal identification number "4586" consisting of four digits is the month and day (year, month, day, hour, minute) of the calendar consisting of four digits, for example, April 30, 8-digit number "458" with "0430" added
“60430” is set as the personal identification number.

In FIG. 3, when the personal identification number is input by the ten-key pad 2 (S1), first, it is verified whether or not the first four-digit number input matches the personal identification number stored in the ROM 1b (S2). . When the collation result is NG, the NG lamp is temporarily turned on (S3), and when the collation result is OK, it is collated whether the subsequent four-digit input matches today's date (S4). Then, when the collation result is NG, the NG lamp is flicker lighting controlled (S5), and
When the value is K, the ID discrimination OK output is sent, the OK lamp is temporarily turned on, and the operator is notified (S6, S7).

In the first embodiment, a new personal identification number is added by inputting at least a part of the personal identification number after the personal identification number. However, a part of the calendar inputting is input before the personal identification number. You may set the thing which added to as a new personal identification number.

Therefore, according to the first embodiment, not the fixed personal identification number itself, but the personal identification number to which the date of the calendar is added is used as a new personal identification number I.
Since the D discrimination is performed, the personal identification number changes day by day, making it difficult for others to understand, and conversely, it is easy for users to understand, and sufficient security can be ensured.

Example 2. Next, FIG. 4 corresponds to the flow chart shown in FIG. 3 of the first embodiment.
It is an operation flowchart based on control of a. In the second embodiment, for example, the personal identification number “11” consisting of four digits
11 ”is the four-digit calendar date, eg April 30
If it is a day, a value obtained by adding "0430", that is, a four-digit number "1541" is set as a personal identification number. Note that it is necessary to select a personal PIN that does not match the PIN obtained as a result of adding a part of the calendar number.

In FIG. 4, when the personal identification number is input by the ten-key pad 2 (S11), whether the input value of the ten-key pad 2 is the same as the sum of the personal identification number and the number input of the calendar, for example, the month and day. Whether or not it is collated (S12), if they do not match, the NG lamp is temporarily turned on (S13), and if they match, the ID discrimination OK output is sent and the OK lamp is temporarily turned on and the operator is notified. (S14, S15).

Although the personal identification number is set to a value obtained by adding at least a part of the calendar to the personal identification number in the second embodiment, a value obtained by subtraction, addition or division other than addition is set. You may set it.

Therefore, according to the second embodiment, the first embodiment
Since the input of the personal identification number by the ten-key pad becomes complicated as compared with the above, the personal identification number is further prevented from leaking, and the security can be further enhanced.

Embodiment 3. When entering a part of the calendar (year, month, day, hour, minute) used as a personal identification number, there is an error in the personal clock etc., so the value of the fountain clock 1d in Fig. 2 is displayed externally and the calendar number is entered. You can reduce the trivial mistakes caused by.

Example 4. The same can be done by using it together with another ID discrimination device such as a card reader.

Example 5. As the secret code, not only addition of the calendar number and secret code, but also subtraction, multiplication, division and any other calculation method can be similarly performed.

[0020]

As described above, according to the present invention, the ID obtained by using the ten-key pad as a new personal identification number is a number obtained by using at least a part of the personal identification number of the calendar. Since the discrimination means for discriminating is provided, there is an effect that the personal identification number changes day by day and it is difficult for others to understand and the security can be enhanced.
