Description

The present invention relates to an information processing device and a program that perform authentication by touching a display unit.

Conventionally, an electronic blackboard such as BIG PAD is known as an information processing device capable of displaying an image on a display unit and writing or drawing characters. There are an increasing number of scenes in which such electronic blackboards are used in meetings and the like, and file servers, cloud servers, etc. are used for viewing materials and saving minutes.

In this case, when logging in to a server or cloud using a pen (input pen) on an electronic blackboard, it is known that the user logs in with a specific gesture sign or the like on the input screen displayed on the display unit. ..

When logging in to a cloud service, for example, if the password is to be entered from the keyboard, it is necessary to connect a hard keyboard or launch a soft keyboard on the display and enter the password. As described above, the conventional electronic blackboard has a problem that the input work becomes complicated.

Further, when a mobile terminal such as a smartphone has a lock function, it has a function of inputting a specific gesture pattern with a finger on the liquid crystal screen of the display unit to unlock the lock. However, since the gesture pattern is limited, there is a possibility that the lock may be easily unlocked by another person, for example, by tracing the fingerprint trace on the liquid crystal screen, which poses a security problem.

Therefore, as a conventional technique, when inputting a code in a mobile terminal, an electronic pictorial book, etc., a color is selected with a touch pen or a fingertip from two or more color selection icons for selecting a color on a mobile terminal equipped with a touch panel screen. It has been proposed that the selected colors are applied to the coloring icons displayed in a matrix on the touch panel screen to authenticate when the preset colors and arrangements are correct (Patent Documents). See 1).

With this configuration, the device can be easily unlocked and a predetermined function can be performed without making the user aware of the code unlock.

Further, as another conventional technique, the password input device can display a plurality of password setting images in which the position and color on the password input screen are specified, and the password setting image can be displayed according to the position and color on the screen. , A password that has been entered has been proposed (see Patent Document 2).

With this configuration, for example, a 4x4 input area is set in advance, and for each input area, the presence or absence of a password setting image and the color of the password setting image, if any, are determined. By determining the password based on the setting information of all the input areas, it is possible to realize highly secure password input with a simple operation.

In the first embodiment, when connecting to a file server, a cloud server, or the like on the electronic blackboard 10, the authentication process is performed by inputting a gesture pattern by touch operation instead of inputting a login password.

The first embodiment is characterized in that the authentication process is performed based on the gesture pattern as the authentication information and the color information as the attribute information of the gesture pattern.

Further, the first embodiment includes a mode in which the pattern traced by the touch pen 20 is not displayed on the gesture pattern input unit 130. As a result, the color information when the pen tip switch unit 220 of the touch pen 20 is switched is not displayed on the screen, but the color information is used as the gesture pattern information.

When performing an authentication operation for logging in to an external server on the electronic blackboard 10, first, the authentication function is activated (step S1). Then, the gesture pattern input unit 130 is displayed on the display unit 120 (step S2).

Then, the determination point is set to the initial value (step S3). Here, the determination point No. 1 is set.

Then, it is determined whether or not the touch operation is detected (step S4). When it is determined in step S4 that the touch operation is detected, it is determined whether or not the pen tip switch unit 220 of the touch pen 20 is in the ON state (step S5).

When it is determined in step S5 that the pen tip switch unit 220 of the touch pen 20 is in the ON state, the touch coordinates in the gesture pattern input unit 130 are acquired (step S6).

Then, it is determined whether or not the acquired touch coordinates are within the authentication point area 131 (step S7). If the acquired touch coordinates are not within the authentication point area 131 in step S7, the process returns to step S6.

If it is determined in step S7 that the acquired touch coordinates are within the authentication point area 131, the coordinates of the corresponding authentication point area 131 are calculated from the detected touch coordinates (step S8), and the calculated authentication is performed. It is determined whether or not the coordinates of the point area 131 match the coordinates read from the authentication pattern table (step S9).

If it is determined in step S9 that the calculated coordinates of the authentication point area 131 do not match the coordinates read from the authentication pattern table, the authentication has failed (step S15). On the other hand, in step S9, when it is determined that the calculated coordinates of the authentication point area 131 match the coordinates read from the authentication pattern table, the color setting of the touch pen 20 used matches the color read from the authentication pattern table. It is determined whether or not to do so (step S10).

If it is determined in step S10 that the color setting of the touch pen 20 used does not match the color read from the authentication pattern table, the authentication has failed (step S15). On the other hand, if it is determined in step S10 that the color setting of the touch pen 20 used matches the color read from the authentication pattern table, the process proceeds to the coordinates of the next determination point (step S11).

Then, it is determined whether or not the touch pen 20 in the touch operation is separated from the gesture pattern input unit 130 (step S12). If it is determined in step S12 that the touch pen 20 is not separated from the gesture pattern input unit 130, the process returns to step S6 and the touch coordinates are continuously acquired.

On the other hand, in step S12, when it is determined that the touch pen 20 is separated from the gesture pattern input unit 130, it is determined whether or not the coordinate value read from the authentication pattern table is X = Y = 0 (step S13). ). If it is determined in step S13 that the coordinate values read from the authentication pattern table are not X = Y = 0, the authentication has failed (step S15).

On the other hand, in step S13, when it is determined that the coordinate value read from the authentication pattern table is X = Y = 0, the acquisition of the touch coordinates is completed and the authentication is successful (step S14). The authentication operation for logging in to the external server ends.

Next, in the electronic blackboard 10 of the first embodiment, the flow of performing the authentication process with the electronic blackboard 10 when the authentication operation is performed by the touch pen 20 will be described with reference to the flowchart.

FIG. 12 is a flowchart showing an operation processing process when performing the certification process using the touch pen on the electronic blackboard of the first embodiment.

If it is determined in step S21 that the color change switch 230 is in the ON state, the ON state information of the color change switch 230 is transmitted to the electronic blackboard 10 (step S22).

In the electronic blackboard 10, the ON state information of the color change switch 230 is received (step S23), and the value of the touch pen state table is updated (step S24).

Then, the value of the touch pen state table is set to +1 (step S25), and the value of the touch pen color table corresponding to the value of the touch pen state table is transmitted to the touch pen 20 (step S26).

In the touch pen 20, the value of the touch pen color table is received (step S27), and the full-color LED is turned on with the color based on the value of the touch pen color table (step S28).

Then, it is determined whether or not the color change switch 230 is in the OFF state (step S29). If it is determined in step S29 that the color change switch 230 is in the OFF state, the OFF state information of the color change switch 230 is transmitted to the electronic blackboard 10 (step S30), and the process ends.

The electronic blackboard 10 receives the OFF state information of the color change switch 230 (step S31), updates the value of the touch pen state table (step S32), and ends.

Then, the determination point is set to the initial value (step S43). Here, the determination point No. 1 is set.

Then, it is determined whether or not the touch operation is detected (step S44). When it is determined in step S44 that the touch operation is detected, it is determined whether or not the pen tip switch unit 220 of the touch pen 20 is in the ON state (step S45).

When it is determined in step S45 that the pen tip switch unit 220 of the touch pen 20 is in the ON state, the touch coordinates in the gesture pattern input unit 130 are acquired (step S46).

Then, the color of the current touch pen 20 is read from the touch pen state table (step S47), and the handwriting stroke is drawn with the color of the current touch pen 20 (step S48).

Then, it is determined whether or not the acquired touch coordinates are within the authentication point area 131 (step S49). If the acquired touch coordinates are not within the authentication point area 131 in step S49, the process returns to step S46.

If it is determined in step S49 that the acquired touch coordinates are within the authentication point area 131, the coordinates of the corresponding authentication point area 131 are calculated from the detected touch coordinates (step S50).

Then, the color of the current touch pen 20 is read from the touch pen state table (step S51), and the coordinates and color information of the current authentication point area of the authentication pattern table are written (step S52).

Then, it is determined whether or not the touch coordinates in the touch operation have changed (step S53). If it is determined in step S53 that the touch coordinates have changed, the process moves to the coordinates of the next determination point (step S11).

Then, it is determined whether or not the touch pen 20 in the touch operation is separated from the gesture pattern input unit 130 (step S55). If it is determined in step S12 that the touch pen 20 is not separated from the gesture pattern input unit 130, the process returns to step S46 and the touch coordinates are continuously acquired.

On the other hand, when it is determined in step S55 that the touch pen 20 is separated from the gesture pattern input unit 130, the X coordinate and the Y coordinate are set to 0 and written in the authentication pattern table (step S56).

Then, the user is asked whether or not to register the current authentication pattern (step S57). If it is confirmed in step S57 that the authentication pattern is registered, the authentication pattern is registered and the process ends.

On the other hand, if it is confirmed in step S57 that the authentication pattern is not registered, the input screen 1210 is cleared, the value in the authentication pattern table is restored (step S58), the process returns to step S42, and the authentication pattern is again performed.

Next, the seventh embodiment will be described.
The electronic blackboard of the seventh embodiment has the same configuration as the electronic blackboard of the first embodiment, and the description of the overall configuration will be omitted.

In the seventh embodiment, the electronic blackboard is characterized in that when the gesture pattern is authenticated, the input attribute of the gesture pattern that matches the preset authentication information is not displayed on the gesture pattern input unit 130.

Specifically, in the gesture pattern input unit 130, input attributes of the gesture pattern that match the preset authentication information, for example, color information and line width information corresponding to the gesture pattern are displayed on the gesture pattern input unit 130. It is configured not to be done.

According to the seventh embodiment, when the gesture pattern is authenticated, the input attribute of the gesture pattern that matches the preset authentication information is not displayed on the gesture pattern input unit 130 in the electronic blackboard. By doing so, it is possible to enable an authentication operation with excellent security without the authentication information being specified by others.

(8th Embodiment)
Next, the eighth embodiment will be described.
The electronic blackboard of the eighth embodiment has the same configuration as the electronic blackboard of the first embodiment, and the description of the overall configuration will be omitted.

The eighth embodiment is characterized in that, when the gesture pattern is authenticated, the gesture pattern is displayed on the gesture pattern input unit 130 by a preset input attribute on the electronic blackboard.

Specifically, the gesture pattern displayed on the gesture pattern input unit 130 is not a gesture pattern related to authentication, but is, for example, a gesture pattern based on preset input attributes (for example, black and white drawing information) that does not include authentication information. There may be.

According to the eighth embodiment, when the gesture pattern is authenticated, the gesture pattern is displayed on the gesture pattern input unit 130 according to the preset input attributes to the other person because of the above configuration. It is possible to enable a highly secure authentication operation without specifying the authentication information.

(9th Embodiment)
Next, the ninth embodiment will be described.
The electronic blackboard of the ninth embodiment has the same configuration as the electronic blackboard of the first embodiment, and the description of the overall configuration will be omitted.

In the ninth embodiment, in the electronic blackboard, a part of the input attribute of the gesture pattern can be changed after registration.

Specifically, when the input attribute of the gesture pattern includes, for example, color information as the authentication information of the gesture pattern, a part of the color information may be configured to be changeable after registration.

Since the configuration is as described above, according to the ninth embodiment, the authentication information can be partially changed by configuring the input attribute of the gesture pattern to be partially changeable after registration in the electronic blackboard. Therefore, it is possible to make it difficult for others to identify the authentication information and enable a highly secure authentication operation.
