Abstract

PURPOSE:To make a user who registers his password freely confirmable at anytime even he forgets his password and, at the same time, to prevent readout of a password by an improper user with a high probability by providing checking items for password retrieval. CONSTITUTION:The 1st storing means 3 which stores checking items for password retrieval and the 2nd storing means 4 which stores passwords and answers to the checking items for password retrieval together with names of specific persons and specific data are provided. Then, at the time of password registration and retrieval, the checking items for password retrieval are displayed and the answers to the checking items for password retrieval inputted from an input means 1 are compared with the answers stored in the 2nd storing means 4 by means of a comparing means 5. When they coincide with each other, the password is displayed in corresponding to the answers to the checking items. Therefore, even when a user forgets his password, the password can be displayed automatically to the user only in a state where none can know the password except the user.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a system in which only a specific person who knows the password can refer to data, and when the password is forgotten, the forgotten password can be retrieved. It concerns a password registration search display method that automatically displays passwords only for you so that others do not know.

(Prior Art) Generally, a system for searching and referencing data simply stores data and extracts necessary data from the data using some kind of search code. In such a system, anyone can freely use the search code that is the basis for searching for necessary data, so it is impossible to register data that you do not want others to refer to.

Therefore, a method has been implemented in which a password is provided and only a specific person who knows this password can view the data.

(Problem to be Solved by the Invention) In the above-described search method using a password, if the password is forgotten, the data cannot be referenced, as a matter of course.

In addition, a typical system that uses this method is a system that has automatic cash dispensers at banks, post offices, etc., but in this system, if you forget your password or enter the wrong password, you will be denied cash. Not only will you not be paid, but your cash card will become invalid. In today's era where each person owns many types of cash cards, it is difficult to remember and enter the passwords attached to multiple cards accurately all the time, so it is a good idea to write down these passwords. You could consider leaving the memo in a safe place, but there is a high chance that the memo will be lost or seen by someone else, making it less secure.

Conventional search methods using passwords have the following problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the password registration search display method provided by the present invention is applicable to a system in which only a specific person who knows the password can refer to specific data. , a password registration search display method for displaying the password only to the specific person, the first storage means storing check items for password search to prevent unauthorized reading of the password; 2. input means for inputting the password and an answer to the password search check item selected corresponding to the password at the time of registration, and inputting the answer to the password search check item when searching for the password; a second storage means for storing the password input from the input means and the answer to the password search check item together with the name of the specific person and the name of the specific data when registering the password; a comparison means for comparing the answer to the password search check item inputted from the input means and the answer to the password search check item stored in the second storage means; At the time of registration and search, display the check items for password search,
If the answer to the password search check item inputted from the input means matches the answer to the password search check item stored in the second storage means as compared by the comparison means, the password is The present invention is characterized by comprising display means for displaying the password stored in the second storage means in correspondence with the answer to the search check item.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a password registration search front thread system according to an embodiment of the present invention.

In the figure, 1 is an input means, 2 is a control means, 3 and 4 are storage means, 5 is a comparison means, and 6 is a display means.

A usage example of this embodiment will be specifically explained.

For example, the password for the Bank A cash card owned by Japan Abehi is r1234. Then, Mr. Nihon Tabe first registers this password using input means 1. As shown in No. 2-, the input means 1 has a structure similar to the keyboard of a personal computer, etc., which is commonly used.
In this embodiment, as shown in FIG.
01'' is entered through the input means 1, the control means 2 displays a screen as shown in FIG. 0 Mr. Tabe Japan enters each data according to the instructions 0 In this example, the name of the person to be registered is 1 Taabe J, the password is rA Bank, and the password number is r1234”
The control means 2 stores these data input from the input means 1 in the storage means 3.

When the password input is completed, as shown in FIG. 5, password search check items are displayed on the display means 6 to prevent unauthorized reading when searching for the registered password number.

Any number of password search check items can be used from among the ten items prepared in advance in the storage means 4, and here three password search check items are used. The user selects his or her favorite answer to each of these password search check items and inputs it using the input means 1. These answers are used as search codes when searching for passwords.

For example, my favorite number is r3, my favorite color is blue, 2j,
If you enter an answer such as "My favorite flower is cherry blossoms" and "2",
The numbers r3-2-2J are stored in the storage means 3 as a search code in the form shown in FIG.

This completes the password registration process of this embodiment, but
If you want to register another password, you can perform the same process.

Next, a process for searching for a forgotten password when Mr. Tabe Nihon forgets the registered password will be explained.

In this embodiment, as shown in FIG.
The code representing "r search" is "02J. When the code "02j" is input from the input means 1, the control means 2
A screen like the one shown in the figure is displayed on the display means 6, and instructions are given to input the registrant's name and password.Following these instructions, 0 Japan Abe will add 1 Japan Abe to the registrant's name. Enter rA Bank 1 as the password target. The control means 2 searches the storage means 3 using these data inputted from the input means 1, retrieves matching data, and obtains the corresponding registered search code (r322j in this case). 6 Mr. Taichi Nihon retrieves the check items for password search from the storage means 4 and displays them on the display means 6 as shown in FIG. input. The answer to each password search check item is something that the person is always aware of, so they will not enter a wrong answer.
Immediately get the search code r322J. Comparison method 5
is the search code input from the input means 1 and the storage means 3.
Compare with the search code stored in . Comparison method 5
When it is confirmed that the two match, the control means 2 displays and notifies the registered password on the display means 6.

Suppose now that an unauthorized person tries to search for Mr. Abe Nippon's password. The fraudulent person used the registrant’s name (“Nippon Abe”)
and the target of the password (rA Bank), but when entering the answer to the password search check item, it is almost impossible to enter the correct answer. There are 10 choices for each, and a maximum of 10 items can be used, so a maximum of 1010 combinations are possible, and even with the usual 3 to 4 check items, 1
This is because there are 000 to 10,000 combinations, so the probability of coincidence by chance is extremely low.

In addition, in order to prevent unauthorized persons who repeatedly enter the password, if there is an unauthorized inquiry for the same registered password five or more times, the contents will be automatically deleted. , it is also possible to apply.

Although the usage example of this embodiment has been described above, this embodiment can be applied not only to a dedicated device for registering and searching passwords, but also to general personal computers, office computers, and the like.

To briefly describe this application, for example, if a password that matches the registered password is entered, a process is executed, and if a password that does not match is entered, a check item is displayed. Here, if a correct answer is obtained, the registered password is displayed and the process is executed, and if a correct answer is not obtained, a message indicating that the user is an unauthorized person is displayed.

(Effects of the invention) As explained above, the present invention registers a password,
By providing a password search check item to prevent unauthorized reading of this password, even if the registered person forgets their password, they can freely check this password at any time. This has the effect of being able to prevent password reading with high probability.
