3A to 3F show display form diagrams of the authentication screen displayed on the display unit 2 of the smartphone 1.

FIG. 3A shows an initial screen for authentication. Images 5a and 5b composed of two ring-shaped line images are displayed on the display unit 2, and symbol images 6a to 6d of spades, clubs, diamonds and hearts as the second images are displayed on the outer periphery of the ring images. Is displayed. Then, between the two ring images 5a and 5b, a numerical image of "0" to "9" is displayed as the first image.
Here, for example, the authentication data is composed of two digits, the first digit is "1", the direction is "clockwise" and the symbol is "spade", and the second digit is "7", direction. Is "counterclockwise" and the symbol is "club".

First, the number image “1” on the display unit 2 is touched. Then, when the touch position is moved clockwise between the ring images 5a and 5b with the touched state, as shown in FIG. 3(b), the number images “0” to “9” are aligned with this movement. Change the display position.
After that, the numeral image “1” is moved to a position corresponding to the spade symbol image 6a, and the finger is released (FIG. 3(c)). By this operation, the input of the first digit data of the authentication data is completed.

Then, the numeral image "7" is touched with a finger, and the touch position is moved counterclockwise while maintaining the touched state. As a result, the display positions of the numerical images "0" to "9" change in accordance with the movement of the touch position (FIG. 3(c)).
Then, as shown in FIG. 3E, when the numeral image “7” is moved and displayed to the position corresponding to the symbol image 6b of the club, the input of the second digit authentication data is completed, and the authentication is completed. Is released.

If at least one of the input “number”, “direction”, and “symbol” is erroneously input in the authentication data at any digit, as shown in FIG. Also, the symbol images 6a to 6d are displayed at new positions, and the input of the authentication data is redone from the beginning.

FIG. 4A to FIG. 4C are display form diagrams in the case where the touch position is moved while the state in which one number image is touched is held.
First, as shown in FIG. 4A, the space between the ring images 5a and 5b is divided into ten areas γ, and one numerical image 7 is displayed in each one area γ. ing. The section γ is divided into a central section α and both end sections β.
Therefore, for example, as shown in FIG. 4B, when the touch position is moved while the number image is being touched and the touch position is within the section β, the display position of the touched number image is the touch position. Moves according to the position.
However, when the touch position enters the section α, the touched numeric image immediately moves to the center position of the section α (FIG. 4C).

When the numerical image is moved and displayed as the touch position is moved in this way, it is possible to obtain a feeling as if the authentication data is being input by a dial having a click feeling.

FIG. 5 is a data layout diagram showing the contents of the data stored in the work RAM 12 and the data layout.
In the work RAM 12, as shown in FIG. 5A, initial screen data necessary for displaying an initial screen for authentication, screen display data during operation used for display during authentication operation, preset authentication data, And the input authentication data to be input are stored. Of these, the initial screen data consists of initial symbol position data and initial numeral position data.Furthermore, this initial symbol position data stores the position data of each of the four symbol images on the display screen. , Position data on the display screen of each of the number images 0 to 9 are stored.

FIG. 5B shows the detailed contents of the operating screen data shown in FIG. As the screen data during operation, position data on the display screen of each of the number images 0 to 9 during the authentication operation is stored.
FIG. 5C shows detailed contents of the input authentication data shown in FIG. This input authentication data is m representing the number of digits of the input authentication data, N representing the number of the input authentication data, D representing the direction of the input authentication data, and the input authentication data. It is composed of four types of data S, which represent data symbols.

FIG. 6 is a data layout diagram showing the contents of the authentication data stored in the program ROM 11 and the data layout thereof.
Unlike the data stored in the work RAM 12, the authentication data is characterized in that its contents are not erased even when the power is turned off.
The authentication data consists of authentication data (1) to authentication data (m), and the authentication data (m) further includes authentication numeral data (m, 1) and authentication direction data (m, 2). And authentication symbol data (m, 3).

The operation of the CPU 10 will be described below with reference to the flowcharts shown in FIGS.
FIG. 7 is a flowchart showing the overall operation of CPU 10. First, when the power switch of the SW unit 3 is turned on, the initialization process of step S1 is executed. Specifically, the contents of the work RAM 12 other than the registers in the CPU 10 and the authentication data are initialized. As a result, the preset value is set in the initial screen data of the work RAM 12. Then, m representing the number of digits in the input authentication data is set to "1".

Then, it transfers to step S2 and performs an authentication process. When the authentication is properly performed by this authentication processing, the mode selection screen is displayed (step S3). Then, one of the modes displayed on this screen is selected, and it is determined whether or not the selected mode is the authentication change mode (step S4). If it is determined that a mode other than the authentication change mode is selected, the process corresponding to the selected mode is executed (step S5), and then the mode selection screen of step S3 is again displayed.

On the other hand, if it is determined that the authentication change mode is selected, the process proceeds to the authentication change process of step S6, and the data required for authentication, specifically, the process of changing the content of the authentication data in the work RAM 11 is performed. To execute. After the end of this process, the process returns to step S3 to display the mode selection screen.
This flowchart is repeatedly processed until the power is turned off by the power switch.

FIG. 8 shows a detailed flowchart of the authentication processing of step S2 in FIG.
First, the authentication screen is displayed on the display screen of the display unit 2. Specifically, the ring image is first displayed (step S21), and subsequently, based on the initial symbol position data and the initial numeral position data of the initial screen data stored in the work RAM 12, the ring image is displayed outside the displayed ring image. Number images 0 to 9 are displayed in the four symbol images and the ring image, respectively (step S22). Then, the contents of the initial numeral position data in the initial screen data is copied to the screen data being displayed (step S23).

Then, it is determined whether or not any of the numerical images displayed in the displayed ring image is touched (step S24). If it is determined that none of the numerical images is touched, the process of step S24 is continued until the touch is made.
On the other hand, if it is determined that one of the numeral images is touched, the numeral at the touched position is stored in the RAM 12 as the input authentication numeral data N (step S25).

After that, it is determined whether or not the finger is moved in the ring image in the clockwise direction or the counterclockwise direction while being touched (step S26). If it is determined that the movement has been made in either direction, the processing moves to the movement processing in step S27.

FIG. 9 shows a detailed flowchart of the moving process in step S27.
First, it is determined whether the touch position is included in the α section at the center of the area displaying each number image in the ring image or in the beta sections at both ends of the area. Yes (step S271). If it is determined that the touch position is included in the α section, the numeric image displayed at the position corresponding to the touch position is immediately moved to the center position of the α section and is not touched. The other numerical images are similarly moved and displayed (step S272). Along with this moving display, each numerical image position data of the operating screen data stored in the work RAM 12 is also changed (step S273).

On the other hand, when the touch position is included in the β section, the display positions of the touched numeric image and the other non-touched numeric images are moved by the movement amount of the touch position (step S274). Also in this case, the process proceeds to step S274, and each numerical image position data of the operating screen data stored in the work RAM 12 is also changed corresponding to the movement of the display position.
Returning to FIG. 7 again, after the moving process of step S27, this moving direction (clockwise or counterclockwise) is stored in the RAM 12 as the input authentication direction data D (step S28).

After the processing of step S28, or when it is not determined in step S25 that the touched finger has been moved, it is determined whether or not the touched finger has been released from the touch screen (step S29). If it is determined that the finger is not released here, the process returns to step S26 again. If it is determined that the finger is released, the process proceeds to step S30, and the symbol is placed outside the ring image at the position where the finger is released. It is determined whether or not an image exists.
That is, it is determined whether or not the display position of the number image moved to the position where the finger is released and the display position of any one of the symbol images are line-symmetrical with respect to the ring image.
Here, when it is determined that the symbol image does not exist, the process proceeds to step S31, and the symbol image and the number image displayed on the display unit 30 are erased. Subsequently, the initial screen data stored in the work RAM 12 is randomly changed (step S32), m representing the number of digits in the input authentication data is returned to "1" (step S33), and the process returns to step S22. Again, the four symbol images are displayed outside the ring image, and the number images 0 to 9 are displayed in the ring image, and the authentication data is input again from the beginning.

On the other hand, if it is determined that the symbol image exists, the type of the symbol image at the position corresponding to the touched position is stored in the work RAM 12 as the input authentication symbol data S (step S34).

After the processing of step S34, the input authentication numeral data N stored in the work RAM 12 matches the authentication numeral data (m, 1), and the input authentication direction data D is the authentication direction data (m, 2). ), and whether or not the input authentication symbol data S matches the authentication symbol data (m, 3) (step S35).
If it is determined that they do not match, as in the case of determining that the finger is released at the position where the symbol image does not exist in step S30, the process proceeds to step S31 and the authentication data is input again. Start over.

On the other hand, if it is determined that they match, the process proceeds to step S36, and m representing the number of digits of the input authentication data is incremented. This means that the next digit of the authentication data is designated. After that, whether or not the value of m exceeds the maximum digit of the authentication data, that is, the last digit of the preset authentication data. It is determined whether the input authentication data has been correctly input, or whether only the middle digit has been input (step S37). If it is determined that the halfway digit has not been input, the process returns to step S24, and the operation of touching and moving the display screen again is performed. On the other hand, when it is determined that the input up to the last digit has been completed, this authentication process is ended and the process returns to the flow of FIG.

FIG. 10 shows a detailed flowchart of the authentication change process of step S6 of FIG.
First, the authentication change screen is displayed on the display screen of the display unit 2. Specifically, the ring image is first displayed (step S61), and subsequently, based on the initial symbol position data and the initial numeral position data of the initial screen data stored in the work RAM 12, the ring image is displayed outside the displayed ring image. Number images 0 to 9 are displayed in the four symbol images and the ring image, respectively (step S62). Then, the contents of the initial numeral position data in the initial screen data are copied to the screen data being displayed (step S63). Then, m representing the number of digits in the input authentication data is set to "1" (step S64).

Then, it is determined whether or not any of the numerical images displayed in the displayed ring image is touched (step S65). If it is determined that none of the numerical images is touched, the process of step S65 is continued until the touch is made.
On the other hand, if it is determined that one of the numeral images is touched, the numeral at the touched position is stored in the RAM 12 as the m-th digit authentication numeral data (m, 1) (step S66). ).

After that, it is determined whether or not the finger is moved in the ring image in the clockwise direction or the counterclockwise direction while being touched (step S67). If it is determined that it has been moved in either direction, the processing moves to step S68. The detailed processing contents of this movement processing are the same as the movement processing shown in FIG.
After the moving process in step S68, this moving direction is stored in the work RAM 12 as the m-th digit authentication direction data (m, 2) (step S69).

After the processing of step S69 or when it is not determined in step S67 that the touched finger has been moved, it is determined whether or not the touched finger has been released from the touch screen (step S70). If it is determined that the finger is not released here, the process returns to step S66 again, and if it is determined that the finger is released, the process proceeds to step S71, and the symbol is placed outside the ring image at the position where the finger is released. It is determined whether or not an image exists.
Here, if it is determined that the symbol image does not exist, the process proceeds to step S72, and the symbol image and the number image displayed on the display unit 30 are erased. Subsequently, the initial screen data stored in the work RAM 12 is randomly changed (step S73), and m representing the number of digits in the input authentication data is returned to "1" (step S74). Then, after that, the process returns to step S65, and again, four symbol images are displayed outside the ring image and each of the number images 0 to 9 is displayed in the ring image, and the change input of the authentication data is redone from the beginning.

On the other hand, if it is determined that the symbol image exists, the type of the symbol image at the position corresponding to the touched position is stored in the work RAM 12 as the authentication symbol data (m, 3) (step S75). After that, the process proceeds to step S76, and m representing the number of digits of the authentication data is incremented. This means that the next digit of the authentication data is designated. After that, whether or not the value of m exceeds the maximum digit of the authentication data, that is, the last digit of the preset authentication data is determined. It is determined whether the change has been input up to, or the change has been completed up to the middle digit (step S77). If it is determined that the change has been completed up to the middle digit, the process returns to step S64, and the operation of touching and moving the display screen again is performed. On the other hand, when it is determined that the input up to the last digit has been completed, this authentication changing process is ended and the process returns to the flow of FIG. 7.

As described above, according to the embodiment of the present invention, when the numerical image 7 of “0” to “9” designated by the touch is combined with any of the four symbol images 6a to 6d as the authentication data. However, since the moving direction of the touch position is also used, it is more difficult to cancel the lock than a combination of numbers or symbols, and the safety of data protection is further enhanced.

Moreover, in order to input this authentication data, one of the four symbol images 6a to 6d is displayed by touching any of the number images 7 of "0" to "9" displayed on the display unit 2. The operation is easy because it is only necessary to perform the operation of moving it to the designated position.
The display unit 2 is relatively small enough to display the number images 7 of "0" to "9" and the four symbol images 6a to 6d.

Further, in the present embodiment, as shown in FIG. 4, when the number image 7 of any of “0” to “9” is touched to move and display from the current number display position to the adjacent number display position, a predetermined number is displayed. The numeral image moves up to the position of (1) in conjunction with the touch position, but when it comes close to the adjacent numeral display position to some extent, it immediately moves to the adjacent numeral display position. For this reason, it is possible to feel the operation as if the conventional mechanical dial were operated.

In the present embodiment, four types of numerical images “0” to “9” and symbol images “spade”, “club”, “diamond”, and “heart” are used, but all of these numbers and types are books. It is not limited to the embodiment. Further, in the present embodiment, a combination of numbers and symbols is used, but a combination of numbers and numbers or symbols and numbers may be used.

Further, in the present embodiment, the number image and the symbol image are arranged in a ring shape, but they may be displayed side by side in the vertical direction or the horizontal direction of the display screen.
Furthermore, in the present embodiment, the electronic device equipped with the authentication device according to the present invention is a smartphone, but it may be another electronic device such as a watch or a tablet.
