Abstract

To solve the following problems of an existing electronic locking/unlocking apparatus: high security cannot be ensured due to the possibility that numerical or character string inputs for locking/unlocking may be read out; different persons cannot draw the same graphic for a key since individual differences may affect drawing the graphic, as well as handwriting; and biometric authentication may fail due to injuries or the like.SOLUTION: An electronic mechanism has an initial screen, an operation start position screen, and an unlocking operation screen divided into two or more areas. In response to a specific operation, a locked screen transitions to the initial screen, and the initial screen transitions to the operation start position screen. One or both of the divided areas displayed as the unlocking operation screen is moved. The locked state is released when match of graphics to be used for determination is visually confirmed, out of ruleless graphics displayed in the display screens, when an operation standby time passes, or when an input for fixation is made.SELECTED DRAWING: Figure 2

Description

The present invention provides screen locking, unlocking, and locking for security protection of smartphones, tablets, PCs, and other display devices with input devices (hereinafter collectively referred to as display devices with input devices). -Related to electronic locking and unlocking devices that apply unlocking to actual devices.

A locked screen on a display device with an input device can be unlocked by inputting numbers or character strings in sequence, by tracing the screen with a finger, by drawing a trajectory with a stylus pen, or by using a special drawing input method. Biometric authentication methods such as fingerprint authentication, which uses a sensor as an input device, and facial authentication, which uses a camera as an input device, are commonly used.

Normal mechanical locks have a locking and unlocking mechanism using a key that utilizes mechanical irregularities, and as a supplement to this, inexpensive locks use number locks, and expensive safes use combination locks. A number lock is considered to be a type of locking/unlocking device that allows you to input numbers by arranging a plurality of ring-shaped objects with numbers written on their surfaces. This method is used on smartphones, tablets, PCs, etc. as a method for numerically inputting the date and time.

JP2019-15157 Dial type locking device JP 07-084661 Information processing device using electronic lock

With existing electronic locking/unlocking devices, when locking/unlocking is performed using a number/character string input method, the input may be read, making it impossible to provide high security. In the figure drawing input method, individual habits affect the input method, just like handwriting, so it is difficult for different people to draw the same figure and use it as a key. With the biometric authentication method, there are cases where authentication cannot be used due to injury, etc., and at the same time, the door cannot be unlocked unless it is registered. For this reason, it is necessary to prepare a second authentication method for graphic drawing input methods and biometric authentication methods, and in this case, it is often a button, character strings arranged at fixed intervals, or numeric input methods.

However, when inputting numbers or character strings, it is easier to decipher them if they have a small number of digits or a small number of selected character types. On the other hand, if the number of digits or character types is large, it is not only complicated to decipher but also difficult to memorize. When functioning as a lock, there are roughly 10 combinations from 0 to 9, and in the case of a 4-digit number lock, 10 000 combinations are possible, but with this number of combinations, one combination is tried in sequence every second. It can be unlocked within 3 hours.

A combination lock can be unlocked by setting the direction and amount of rotation, but there are two directions of rotation: right or left, and the amount of rotation is often 100 because it is measured using a scale. It is possible to perform a combination of 200 to the 4th power with 4 rotations, but with a dial with an angle increment of 3.6 degrees and a diameter of 50 mm, the outer arc length is in increments of less than 1 mm, so in order to input an accurate position, Requires slow operation.

The electronic locking/unlocking device according to the present invention includes an initial screen 101 and an operation start position screen 102 on a display device 001, and during an unlocking operation, the operation start position screen 102 has a screen area divided into at least two parts. The operator moves either or both of the divided screens (106 and 107) using the input device 002, enlarges or reduces the unlocking operation screen 103, and visually matches the screen. After the operator makes a decision, the operator stops the movement input and inputs a confirmation, or waits for a certain amount of time to unlock, and then locks the door after a certain amount of time has elapsed in the unlocked state or by performing a locking operation through the input device. This is what we do.

The images displayed on the display device 001 to visually judge a match are still images or moving images, and include a figure for judging a match (hereinafter referred to as a judgment figure) and a figure similar to the judgment figure (hereinafter referred to as a camouflage figure). (referred to as figures) are characterized by being arranged two-dimensionally at irregular intervals.

Because the judgment shapes and camouflage shapes are arranged at irregular intervals, it is difficult to predict the number of combinations, and an operator who knows the official unlocking screen (hereinafter referred to as the official operator) can easily match them. On the other hand, it is extremely difficult for an operator (hereinafter referred to as a non-regular operator) who does not know the regular judgment figure to recognize it.

By separately providing the initial screen 101 and the operation start position screen 102, authorized operators can easily reach the operation start screen by using screen movement operations, scaling operations, etc., while non-authorized operators can easily reach the operation start screen by using screen movement operations, scaling operations, etc. Since it is difficult to reach the location screen 102, higher security can be achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out the invention will be explained using the drawings. Note that the names, operations, etc. of the components described in this embodiment are not intended to limit the technical scope of the present invention.

FIG. 1 shows an example of the configuration of an apparatus according to the present invention. The device is composed of a display device 001 and an input device 002, and a receiving device 003 that receives an input signal from the input device 002, and a control device that decodes the signal received by the receiving device 003 and switches the display state of the screen of the display device 001. A device 004 is provided. In addition to the display state of the screen, the control device 004 also has a function of transmitting necessary unlocking information to the external system 005.

FIG. 2 is a flowchart showing the relationship and order of input operations and displayed screens in the present invention. The authorized operator performs a start operation 110 using the input device 002. This operation may be any operation, and may be an operation that indicates a special signal if the security level is to be improved. For example, if the input device 002 has arrow keys, inputs include "←", "↓", and "↑".

When the start operation 110 is confirmed, an initial screen 101 is displayed on the display device 001. Furthermore, when the operator performs a predetermined input (hereinafter referred to as normal initial input) as the operation input 111, the operation start position screen 102 is displayed on the screen of the display device 001. Even if the operator is a regular operator, if the input is incorrect, the initial screen 101 is not displayed, and the movement screen 106 corresponding to the amount of input is displayed. Although the operation wait state continues, the operation start position screen 102 cannot be reached until a regular initial input is performed.

When the operation start position screen 102 is displayed, the operator can visually see two divided screens 106 and 107. The input device 002 is used to specify whether the screen to be operated is the divided screen 106 or 107, and the input device 002 is used to instruct movement of the screen. If the lock is simple, the screen for movement operations may be fixed to either 106 or 107. The result of screen movement is displayed as an unlocking operation screen 103, and if the image information displayed at irregular intervals displayed on screens 106 and 107 becomes a judgment figure, wait for the next operation and wait for a certain time. The input is completed and unlocking is recognized when the time period elapses or a specified operation is performed. If the unlocking operation screen 103 does not show the determined figure, the display of the unlocking operation screen 103 is changed and the screen waits for an operation.

When a state is reached in which unlocking is recognized, the control device control device 004 performs an operation. The operations performed here include unlocking by communicating with the external system 005, and waiting for the next input accompanied by a change in the display on the display device 002. By combining waiting for the next input, it is also possible to perform more complex locking with multiple stages.

Figure 3 shows examples of determination shapes and camouflage shapes. The figures used for determination are determination figures 201 and 202, and the figures used for camouflage are camouflage figures 203, 204, etc. In this example, what is displayed on the screen 106 is a determination figure 201, a camouflage figure 203, etc., and what is displayed on the screen 107 is a determination figure 202, a camouflage figure 204, etc.

Although the display device 001 and the input device 002 have been described here as physically separate devices, a touch panel type input/output device can also be used, or a pad type computer or PC can also be used. In this case, screen selection and movement operations can be performed by operations called flicks, swipes, drags, and the like.

FIG. 4 shows the positional relationship between the initial screen 101, the operation start position screen 102, and the unlocking operation screen 103. The initial screen 101 is arranged at a position that has no particular relationship with the operation start position screen. On the operation start position screen 102, an unlock operation screen 103 is displayed at the same time as the operation input starts. Judgment figures 201 and 202 and camouflage figures 203 and 204 shown in FIG. 3 are displayed on the unlocking operation screen.

Figure 5 shows the range relationship between the operation start position screen and the unlocking operation screen. It is preferable for the operation to transition from the initial screen 101 to the operation start position screen 102 in such a way that only the necessary portions can be displayed on the unlocking operation screen 103. However, this is not desirable as a security measure, which is the original purpose. In order to prevent this, it is preferable to once display an area that completely encompasses the unlocking operation screen 103 as the operation start position screen 102, and then performing the unlocking operation by scaling and moving the screen through the input device 002. It is preferable to change the portion displayed as the operation start position screen 102 and the display magnification each time. A regular operator can easily find the target determination figure or camouflage figure even if the display position or magnification is different.

FIG. 6 shows the relationship between the displayable initial position space 108 and the initial position screen. The initial position screen may display the same initial screen 101 each time, but may also be displayed at a different position 109 or the like. As a result, this has the effect of making anyone other than the authorized operator who recognizes the difference in position think that it is difficult to unlock the lock.

Next, as a second embodiment, a case where the regular figure and the camouflage figure are different from those in the first embodiment will be described with reference to FIG. Even if the key in Figure 3 is sufficient for its function, it may be difficult for humans to memorize and recognize it in a short period of time. The basic combination 211 in FIG. 7 is set as an unlocked position in the same positional relationship as in FIG. 3, and line segments are arranged at irregular intervals. The difference is that the thickness of some line segments has been changed. In addition, in the arc camouflage 212, although the semicircle (semi-ellipse) is used to make it difficult to recognize the irregular arrangement, a regular operator can easily recognize the positional relationship and set the unlocked position. Furthermore, if the camouflage 213 is made of patterned circular arcs, the positional relationship can be more easily recognized and the unlocked position can be set.

As the next example, a case where photographs are used as determination figures and camouflage figures will be explained using FIG. 8. In FIG. 8, a building end face 223 of a building 222 in a city background 221 lined with buildings and a cargo compartment end face 226 of a freight vehicle 225 in a foreground 224 where a vehicle is traveling are used as determination figures. Since the entire layout is a camouflage figure with a lot of irregularities, it is difficult for unauthorized users to find matching positions. Note that in FIG. 8, the split screen of still images is moved as in the conventional case, but if the moving image of the vehicle is replaced, the unlock position can be set without splitting the screen.

The divisions shown so far are in-plane divisions. It is also possible to have separate display layers as a background 221 and a foreground 224, make the foreground 224 semi-transparent, and overlap the background 221 as shown in FIG. 9 for display.

In the embodiments shown so far, the case where the screen is divided horizontally into two has been explained. However, the number of divisions may be three or more, and the arrangement may be vertical as well as horizontal, diagonal, or at multiple angles. Furthermore, as described in the fourth embodiment, by providing a plurality of layers, these displays can be made easier. By moving in a straight line, it is possible to give the impression that the range is infinite, which can also have the effect of discouraging non-regular users. Although it is possible to arrange them concentrically, it is preferable to arrange them so that the entire circumference is not visible. This is because there seem to be an infinite number of combinations.

Up to this point, the embodiment has been described as a locking/unlocking mechanism, but it can also be applied as a locking/unlocking mechanism that does not have the concept of a key, such as games or screen savers.
