Description

  Embodiments described herein relate generally to an authentication device, an authentication method, and an authentication program.

  Conventionally, in office buildings, factories, and the like, authentication processing is performed using an electronic lock, thereby managing the persons entering the area where entry is restricted.

  In this electronic lock, a user enters a recitation number using a numeric keypad on which numbers are displayed, and the input recitation number and registration information stored in the database as a recitation number that identifies a regular resident in advance. Is checked to determine whether or not the person entering the room is a regular person, and when the person is authenticated as a regular person, the door to the corresponding area is unlocked.

  Such an authentication process by inputting a recitation number is also used in ATMs (Automated teller machines) of banks.

  However, in such an authentication process using an electronic lock, when the number of users is relatively limited, the password is illegally entered by another person due to the dirty condition of the numeric keypad or the movement of the hand when the operator is viewed from behind. There was a problem that skimming may occur.

  As countermeasures against these, an authentication device is configured to display a numeric keypad for inputting a recitation number on the display device as image information, and image information is generated so that each numeric display position of the numeric keypad is randomly assigned each time. There is technology. A numeric keypad based on image information generated in this manner is generally called a magical numeric keypad, a scramble numeric keypad, or a random numeric keypad, and is widely used.

  However, when the image information is generated by randomly assigning each numeric key display position each time as in the authentication device described above, it is necessary to provide an input interface that applies a touch panel to a dot matrix display. Such a display is complex in circuit and expensive to build.

  Further, in the above-described authentication device, the numeric keypad numbers are displayed on the display using image information. Therefore, the visibility may be low depending on the resolution, and the operator may mistake the numbers.

  Further, in the above-described authentication device, it is necessary to provide a backlight on the display device in order to make the image information on the numeric keypad operable at all times at night, which increases power consumption.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an authentication device, an authentication method, and an authentication program capable of performing highly accurate authentication processing with a simple configuration.

  According to the embodiment for achieving the above object, the authentication device includes an input unit, a user information storage unit, a switch information generation unit, and an authentication unit. The input unit includes a plurality of switches arranged in a matrix and capable of being turned on in any one of a plurality of colors. The user information storage unit stores regular user identification information in which a plurality of pieces of color information are combined in a specific order for each regular user. The switch information generation unit generates switch information indicating correspondence between the position information of each switch and the color information to be lit. When the switch is pressed, the authentication unit determines the color information corresponding to the position information of the pressed switch based on the switch information, further acquires the order of the determined color information, When the order matches the regular user identification information, the user who performed the pressing operation is authenticated as a regular user.

If it matches the regular user identification information, the user who performed the pressing operation is authenticated as a regular user.

  The RAM 40 is a volatile memory, stores switch information generated by the switch information generation unit 32, and is determined by the input information determination unit 33 each time the user presses the input switch of the input unit 10. The color information of the selected switches is sequentially stored.

  The display unit 50 displays the authentication result by the authentication unit 34 in order to notify the user.

<Operation of Authentication Device According to First Embodiment>
Next, the operation of the authentication device 1 according to the present embodiment will be described.

  In the present embodiment, when the authentication device 1 is operated, regular user identification information is stored in the ROM 20 in advance.

  An example of authorized user identification information stored in the ROM 20 is shown in FIG.

  In the regular user identification information shown in FIG. 4, the color order information “red → pink → orange → green” is registered as identification information for the user A who is a regular user, and the color order information “ It is assumed that “yellow → blue → yellow → red” is registered.

  The operation of the CPU 30 of the authentication device 1 when the authentication process is executed in a state where the regular user identification information is stored in the ROM 20 will be described with reference to the flowchart of FIG.

  First, when the start switch 100 is pressed to start an authentication process for unlocking by a user who wants to enter an area to be managed (S1), application information stored in the ROM 20 by the CPU 30 is stored in the RAM 40. The authentication process is started.

  Next, in the switch information generation unit 32 of the CPU 30, switch information indicating the correspondence between the position information of the switches 101 to 116 of the input unit 10 and the color information to be lit is generated and stored in the RAM 40.

  An example of the switch information stored in the RAM 40 is shown in FIG. In the switch information illustrated in FIG. 6, among the switches 101 to 116 of the input unit 10, the switches 101, 102, 104, 106, 107, 109, 112, 114, and 115 are “colorless”, and the switch 103 is “red”. , Switch 105 is “blue”, switch 108 is “orange”, switch 110 is “pink”, switch 111 is “yellow”, switch 113 is “light blue”, and switch 116 is “green”.

  The generated switch information is sent to the input unit 10, and the switches 101 to 116 are lit in a corresponding color based on the switch information (S2). An example of a state when the input switches 101 to 116 are turned on is shown in FIG.

  In this way, when any of the switches is pressed by the input unit 10 by the user while the switches 101 to 116 are lit in the corresponding colors, this is detected by the input information acquisition unit 31 and the type of switch ( A start switch or an input switch) is determined (S3).

  Next, the input information determination unit 33 determines the position information of the pressed switch based on the switch information stored in the RAM 40 when the input information acquisition unit 31 determines that any of the input switches has been pressed. The color information corresponding to the position information is further determined. The determined color information of the pressed switch is stored in the RAM 40 (S4).

  For example, when the switch 103 is pressed by the user, the input information acquisition unit 31 detects that the “input switch” is pressed, and the input information determination unit 33 detects the position information “third column, first row based on the switch information”. The color information “red” is further acquired, and this color information “red” is stored in the RAM 40 as the first switch pressing information.

  The switch color information is determined and stored in the RAM 40 by a predetermined number (four in this embodiment) of switch colors corresponding to the authorized user identification information stored in the ROM 20 by a plurality of switch operations by the user. It repeats until information is acquired (S5).

  When a predetermined number of color information is acquired in step S5 and stored in the RAM 40, the order of these color information is acquired in the authentication unit 34 (S6).

  For example, here, color information “red” by pressing the first switch → color information “pink” by pressing the second switch → color information “orange” by pressing the third switch → color information “green” by pressing the fourth switch ”, The order of the color information is acquired.

  Next, the authentication unit 34 determines whether or not the user who has performed the operation is a regular user based on the order of the acquired color information and the regular user identification information stored in the ROM 20 in advance. (S8).

  Here, since the order “red” → “pink” → “orange” → “green” of the color information acquired by the authentication unit 34 is the same as “user A” in the regular user identification information, the operation is performed. The performed user is authenticated as “user A” as a regular user (“YES” in S8).

  If the authentication unit 34 determines that the user is an authorized user, information for notifying the user that the authentication has been successful is displayed on the display unit 50 (S9), and the management area is locked (not shown). Is unlocked.

  According to the above-described embodiment, the configuration is such that the input switch is identified using the color information, so that the process of randomly assigning the switch color information can be easily performed every time the authentication process is performed. The user can easily store the identification information, and the authentication process with high accuracy can be performed.

<< Second Embodiment >>
<Configuration of Authentication Device According to Second Embodiment>
Since the configuration of the authentication device 2 according to the second embodiment of the present invention is the same as the configuration of the authentication device 1 according to the first embodiment, detailed description thereof is omitted.

<Operation of Authentication Device According to Second Embodiment>
Next, the operation of the authentication device 2 according to the present embodiment will be described.

  In the present embodiment, as regular user authentication information, as shown in FIG. 8, identification information “blue → blue → upper right colorless → green” consisting of switch position information and color order information is registered for user C. And

  In this way, the authentication process is executed in the state where the regular user identification information is stored in the ROM 20, and the start switch 100 is used to start the authentication process for unlocking by the user who wants to enter the management target area. When pressed (S1), the switch information generation unit 32 of the CPU 30 generates switch information indicating the correspondence between the position information of each of the switches 101 to 116 of the input unit 10 and the color information to be lit, and is stored in the RAM 40. .

  In the present embodiment, it is assumed that the switch information of FIG. 6 is generated, and among these, the switch 104 of the position information “fourth column, first row” is always fixed to be “colorless”.

  The generated switch information is sent to the input unit 10, and the switches 101 to 116 are lit in a corresponding color based on the switch information (S2).

  In this way, when any of the switches is pressed by the input unit 10 by the user while the switches 101 to 116 are lit in the corresponding colors, this is detected by the input information acquisition unit 31 and the type of switch ( A start switch or an input switch) is determined (S3).

  Next, the input information determination unit 33 determines the position information of the pressed switch based on the switch information stored in the RAM 40 when the input information acquisition unit 31 determines that any of the input switches has been pressed. The color information corresponding to the position information is further determined. The determined position information and color information of the pressed switch are stored in the RAM 40 (S4).

  For example, when the switch 104 is pressed by the user, the input information acquisition unit 31 detects that the “input switch” is pressed, and the input information determination unit 33 detects the position information “fourth row, first row based on the switch information”. Eye (upper right) "is acquired, and further color information" colorless "is acquired, and the fixed position information and color information" fourth column, first row (upper right) colorless "are stored in the RAM 40 as switch pressing information. The

  The switch position information and color information are determined and stored in the RAM 40 by a predetermined number (four in this embodiment) corresponding to the regular user identification information stored in the ROM 20 by a plurality of user switch operations. The process is repeated until switch position information and color information are acquired (S5).

  When a predetermined number of position information and color information are acquired in step S5 and stored in the RAM 40, the authentication unit 34 acquires the order of these position information and color information (S6).

  For example, here, the color information “blue” when the first switch is pressed → the color information “blue” when the second switch is pressed → the position information and the color information “upper right color” when the third switch is pressed → the fourth switch is pressed It is assumed that the position information of color information “green” and the order of color information have been acquired.

  Next, in the authentication unit 34, based on the order of the acquired position information and color information and the regular user identification information stored in advance in the ROM 20, it is determined whether or not the user who performed the operation is a regular user. It is determined (S8).

  Here, the order “blue” → “blue” → “upper right colorless” → “green” of the position information and color information acquired by the authentication unit 34 is the same as “user C” in the regular user identification information. The user who has performed the operation is authenticated as “user C” as a regular user (“YES” in S8).

  If the authentication unit 34 determines that the user is an authorized user, information for notifying the user that the authentication has been successful is displayed on the display unit 50 (S9), and the management area is locked (not shown). Is unlocked.

  According to the above embodiment, since the switch position information is added to the identification information in addition to the color information, the number of users to be managed can be increased and a highly accurate authentication process can be performed.

<< Third Embodiment >>
<Configuration of Authentication Device According to Third Embodiment>
Since the authentication device 3 according to the present embodiment has the same configuration as that of the authentication device 1 according to the first embodiment, detailed description of components having the same functions is omitted.

  The switches 101 to 116 of the input unit 10 in the present embodiment can be lit in any one of a plurality of colors, and can display different numerical information together.

  The ROM 20 according to the present embodiment includes a combination of color identification information in which color information of a plurality of switches, which is registered in advance by an authorized user, is combined in a specific order, and numerical information corresponding to each of the color information. The number identification information is stored as regular user identification information.

  In addition, the switch information generation unit 32 according to the present embodiment, when the input information acquisition unit 31 determines that the start switch 100 is pressed, the position information of the switches 101 to 116 of the input unit 10, the color information to be lit, Switch information indicating the correspondence with the displayed numeric information is generated and stored in the RAM 40, and the input switches 101 to 116 of the input unit 10 are lit in a predetermined color and the numerical information is displayed based on the generated switch information. .

  In addition, the authentication unit 34 according to the present embodiment acquires the order of the color information and the number information of the pressed switch based on the position information of the pressed switch sequentially stored in the RAM 40, and the acquired number information and When the order of the color information matches the regular user identification information stored in the user information storage unit, the user who performed the pressing operation is authenticated as a regular user.

  The RAM 40 is a volatile memory, stores switch information generated by the switch information generation unit 32, and is determined by the input information determination unit 33 each time the user presses the input switch of the input unit 10. The order of the color information and numeric information of the switches that have been selected is sequentially stored.

<Operation of Authentication Device According to Third Embodiment>
Next, the operation of the authentication device 3 according to the present embodiment will be described.

  In the present embodiment, as regular user authentication information, as shown in FIG. 9, identification information “orange → blue → colorless → green” consisting of switch position information and color order information with respect to user D, and corresponding to this It is assumed that number identification information “2307” is registered.

  Thus, when the authentication process is executed in the state where the authorized user identification information is stored in the ROM 20, the start switch is used to start the authentication process for unlocking by the user who wants to enter the management target area. When 100 is pressed (S1), switch information indicating the correspondence between the position information of each of the switches 101 to 116 of the input unit 10, the number information to be displayed, and the color information to be lit is generated and stored in the RAM 40.

  In this switch information, the correspondence between the color information to be lit and the numerical information to be displayed is preset for each user stored as the regular user identification information and stored in the ROM 20. Are classified into 10 colors that are easy to identify, and each color is set to correspond to numeric information “0” to “9”. An example of the switch information generated for the user D in the present embodiment is shown in FIG.

  In the switch information shown in FIG. 10, among the switches 101 to 116 of the input unit 10, the switches 101, 102, 104, 106, 107, 109, 112, 114, and 115 are “colorless: display number“ 0 ””, Switch 103 is “red: display number“ 1 ””, switch 108 is “orange: display number“ 2 ””, switch 105 is “blue: display number“ 3 ””, and switch 110 is “pink: display number“ 4 ”. ", Switch 111 is stored as" yellow: display number "5" ", switch 113 is stored as" light blue: display number "6" ", and switch 116 is stored as" green: display number "7" ".

  Further, the generated switch information is sent to the input unit 10, and based on the switch information, the switches 101 to 116 are lit in a corresponding color and numbers are displayed (S2).

  When one of the switches is pressed by the input unit 10 in a state where the switches 101 to 116 are lit in the corresponding colors and the corresponding numbers are displayed, the input information acquisition unit 31 This is detected, and the type of switch (start switch or input switch) is determined (S3).

  Next, the input information determination unit 33 determines the position information of the pressed switch based on the switch information stored in the RAM 40 when the input information acquisition unit 31 determines that any of the input switches has been pressed. Further, color information and numerical information corresponding to the position information are further determined. The determined color information and numeric information of the pressed switch are stored in the RAM 40 (S4).

  For example, when the switch 108 is pressed by the user, the input information acquisition unit 31 detects that the “input switch” is pressed, and the input information determination unit 33 detects the position information “fourth row, second row based on the switch information”. The color information “orange” and the numerical information “2” are acquired, and the color information “orange” and the numerical information “2” are stored in the RAM 40 as the first switch pressing information.

  At this time, the user can input using either the user identification information stored based on the color information or the user identification information stored based on the number identification information.

  The determination of the color information and numerical information of the switch and the storage in the RAM 40 are performed by a predetermined number (four in the present embodiment) corresponding to the regular user identification information stored in the ROM 20 by a plurality of switch operations by the user. The process is repeated until the switch color information and number information are acquired (S5).

  When a predetermined number of color information is acquired in step S5 and stored in the RAM 40, the order of the color information and number information is acquired in the authentication unit 34 (S6).

  For example, here, color information “orange” by pressing the first switch, number information “2” → color information “blue” by pressing the second switch, number information “3” → color information “colorless” by pressing the third switch ”, The number information“ 0 ”→ the color information order of the color information“ green ”and the number information“ 7 ”obtained by pressing the switch for the fourth time is acquired.

  Next, in the authentication unit 34, whether or not the user who performed the operation is a regular user based on the order of the acquired color information and numeric information and the regular user identification information stored in the ROM 20 in advance. It is determined (S8).

  Here, the order of color information “orange” → “blue” → “colorless” → “green” acquired by the authentication unit 34 and the order of number information “2” → “3” → “0” → “7” Since it is the same as “User D” in the regular user identification information, the user who performed the operation is authenticated as “User D” of the regular user (“YES” in S8).

  If the authentication unit 34 determines that the user is an authorized user, information for notifying the user that the authentication has been successful is displayed on the display unit 50 (S9), and the management area is locked (not shown). Is unlocked.

  According to the present embodiment described above, since the input switch is identified by using the color information and the numerical information, the user can use the color identification information and the number identification information for authentication information. Further, since the correspondence between the color information and the numerical information varies depending on the user, the effect of preventing skimming can be improved, and more accurate authentication processing can be performed.
