Abstract

PURPOSE:To attain an easy application of a password system for a user and to improve the protection of secrecy by performing a grid display at a prescribed area of a display, etc. and indicating the grid display with a light pen, etc. to feed a graphic as a password. CONSTITUTION:The grids are produced in a request mode for password input and displayed at a display 21. A user uses a pointing device 22 to feed a graphic password. Then the position of the password in the grid coordinates is detected by a position detector 24 and stored to a reference position memory 26. The points fed successively are converted into relative positions by a relative position calculating part 27 and stored in the order indicated by a graphic temporary memory part 28. When the end is indicated for input of the password, the registered graphic passwords are retrieved successively and collated with each other by a collation/retrieval part 29. Then the input operator of the password is permitted as the relevant user when the coincidence is obtained between the fed graphic password and the user's graphic password registered previously.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is used to identify an individual user in a computer, a bank deposit dispensing machine, etc., or when a computer file or database is used. Concerning the password method used in identifying the password.

[Technical background of the invention and its problems]

In computers and bank teller machines, when identifying a user, a finite sequence of numbers or a finite sequence of numbers and letters is used as a password from an input device such as a keyboard. By checking the input data and comparing it with the patterns registered and recorded in the computer, etc., and determining the user/individual, the town authority can control access to the computer (i.e., the computer is available for use, the payment is made), the files, and the database. or processing deposit withdrawals. Conventionally, such a password input method has been widely used. This is thought to be due to the fact that keyboards are often used as input devices.

However, the password is a finite sequence of 110 numbers.

Or a finite sequence of numbers and letters.

The problem is that it is difficult for humans to remember intuitively. In particular, sequences with long digits are difficult for humans to understand. Passwords are intended to protect confidentiality from others, so it may seem that passwords are difficult to remember, but they are actually difficult for users to remember, and they are easily forgotten unless they are kept in a notebook or other form of notes. It is common sense to put it away. Therefore, passwords of at most 4 digits, and at most 8 digits, are used. However, because they are often used, there is a tendency for family members' birth dates and other numerical strings that are often used by users to be used as passwords9.
Or, the password is often known to others because it is written in a memo or the like. This means that the significance of entering a password as a means of protecting confidentiality and confirming the identity of the user will be lost. On the other hand, there is a high possibility that the person in question will forget the password, and there were many cases where the user forgot even a four-digit password and was unable to use computers.

[Object of the Invention] In view of the above, an object of the present invention is to provide a password system that improves security performance and is highly flexible.

[Summary of the invention]

In the password input method, the present invention displays a grid in advance on a predetermined part of a display, etc., and instructs the user to input one figure as a password by sequentially instructing it using pointing means such as a light bar or a mouse. The password user is identified by collating and publishing the graphics.

〔Effect of the invention〕

According to the present invention, one figure can be used as a password and can be input, so that a figure that is easy for the user to remember and consists of a long ordered sequence can be used as a password. Memorizing your password as a visual pattern will make it easier for you to forget it, reduce the need to write it down in notes, etc., and reduce the chance that your password will be revealed to others. Moreover, when using a graphic password, the number of possible combinations increases dramatically compared to when using a string of numbers. This improves the performance of secret mining, and allows the use of more flexible passwords.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an example of a screen when password input is requested on a single display. A grid is displayed in the password input area. FIG. 2 is an example of the configuration of an apparatus in an embodiment for explaining the present invention. Here (2
1) is the display, (22) is the light pen/(mouse,
(23) is a grid generator, (24) is a position detector, (25) is a control unit, (26) is a reference position storage unit, (27) is a relative position i

9) is a verification search section, and (210) is a graphic password registration section. FIG. 3 is an explanatory diagram for explaining the graphical password input method according to the present invention. Figure 3 (a), (b)
), '(d) are diagrams for explaining each of the one-figure passwords.

[Phase] is the point first indicated to the user as a reference point.

FIG. 3(C) is an example of an ordered sequence (figure) of the positions of a finite number of points sequentially designated, where el is a figure password.

Here, the figure is defined as an ordered sequence of point positions as shown in Figures 3(C) and (e), rather than ``Figures 3 (a), (b); (d) themselves.

The present invention will be described with reference to FIGS. 2 and 3.

At the time of a password input request, a grid is generated by the grid generating section (23) according to an instruction from the control section (25) and displayed on the display (21). At the same time, a password input request is made (Fig. 1). Here, the user (2
Start inputting the 1-shape password using the pointing device in 2).

The position (Xo, Yo) of the first point indicated by the user in the grid coordinates is detected by the position detector (24) and stored in the base Jfi position 1 loaf storage section (26) through the control section (25). be done. The user continues to input the graphic password. At this point, the position (XI, Yi) of the indicated point is detected by the position detector (24), and then the position is detected by the relative position meter' through the control unit (25). Part A (
27) so that Xi = Xi −Xo, Yi = Yi−Y
Perform the transformation o.

The resulting relative positions it (Xi, Yi) are read and stored in the graphic temporary storage section (28) in the instructed order. This will be explained with reference to FIG.

In FIGS. 3(a) and 3(b), although the coordinates of the points on the grid are different, the relative positions from the reference point are equivalent. Figure 3(a)
For (b), Fig. 3 (
(a), (b), (c), and (b) of C) are shown. In addition to this, different sequences can be considered from FIGS. 3(a) and 3(b).

Further, an example of the sequence for FIG. 3(d) is shown in FIG. 3(e). In this way, reading and shi figure temporary storage part (28)
An ordered sequence of graphical passwords is stored in . If you finish entering the password by pointing to the upper left corner of the grid section, the graphic password entered under the instruction of the control section and the graphic password addition section (2
10) Search sequentially for the graphic passwords registered in
The matching operation is performed by the matching search section (29). When the graphical password input here is compared with the graphical password of the user registered in advance, the person inputting the password is recognized as the corresponding user.

Here, in Figure 3 (C1 graphical password, (a)
, (b), ←→, ni) are equivalent to each other. Therefore, since a very large number of different graphic passwords can be set for the same pattern, the possibility that someone else will know about the pattern even if the shape is relatively simple is reduced accordingly.

The present invention is not limited to the above embodiments. For example, in the above example, the solid is defined as an ordered sequence of a finite number of points specified sequentially, but if the solid is an ordered sequence of line segments,
Also as an ordered sequence of points and line segments.

Furthermore, K can be realized as an ordered sequence of patterns including circles, triangles, and general basic figures without changing the gist of the present invention. Also a point as a figure.

Even in the case of a pattern in which the order of line segments is not assumed, it is possible to implement the present invention without changing the gist of the present invention.
