Description

  The present invention relates to an information processing apparatus and a program for performing authentication by a touch operation on a display unit.

  2. Description of the Related Art Conventionally, an electronic blackboard such as BIG PAD is known as an information processing apparatus capable of displaying an image on a display unit and writing and drawing characters. Increasingly, such electronic blackboards are used in meetings and the like, and file servers, cloud servers, and the like are used for browsing documents and storing minutes.

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

  The pen software attached to the conventional electronic blackboard has a function of calling and saving a file by connecting to a cloud service. When logging in to the cloud service, for example, when a password is input from a keyboard, it is necessary to connect a hard keyboard or launch a soft keyboard on the display unit and input the password. Thus, the conventional electronic blackboard has a problem that the input operation becomes complicated.

  Further, in the case where a mobile terminal such as a smartphone has a lock function, it has a function of releasing a lock by inputting a specific gesture pattern with a finger on the liquid crystal screen of the display unit. However, since the gesture pattern is limited, there is a risk that the lock can be easily unlocked by another person, for example, by tracing the fingerprint trace on the liquid crystal screen.

  Therefore, as a conventional technique, when inputting code in a portable 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 portable terminal having a touch panel screen. A method is proposed in which the selected color is applied to coloring icons arranged and displayed in a matrix on the touch panel screen, and authentication is performed when the preset color and arrangement are correct (Patent Literature). 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 release.

  Further, as another conventional technique, a 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. In this proposal, an input password is discriminated (see Patent Document 2).

  By configuring in this way, for example, a 4 × 4 input area is set in advance, and for each input area, the presence / absence of a password setting image and the color when there is a password setting image are determined, By determining the password based on the setting information of all the input areas, it is possible to realize a highly secure password input with a simple operation.

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

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

  In the first embodiment, a mode in which a pattern traced with the touch pen 20 is not displayed on the gesture pattern input unit 130 is provided. Thereby, 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.

  In the electronic blackboard 10, when an authentication operation for logging in to an external server is performed, an authentication function is first 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 an initial value (step S3). Here, determination point No = 1.

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

  If it is determined in step S5 that the pen point 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 in 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, if it is determined in step S9 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 perform (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, when it is determined in step S10 that the color setting of the used touch pen 20 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 has left 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 acquired.

  On the other hand, when it is determined in step S12 that the touch pen 20 has moved away 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 value read from the authentication pattern table is not X = Y = 0, the authentication has failed (step S15).

  On the other hand, if it is determined in step S13 that the coordinate value read from the authentication pattern table is X = Y = 0, the acquisition of touch coordinates is terminated 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, a flow of performing an authentication process with the electronic blackboard 10 when performing an authentication operation with the touch pen 20 will be described along a flowchart.

  FIG. 12 is a flowchart showing an operation processing step when the authorization processing is performed using the touch pen in the electronic blackboard of the first embodiment.

First, when performing an input operation for logging in using the touch pen 20, it is determined whether or not the color change switch 230 for performing color change is in an ON state (step S21).
When 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).

  The touch pen 20 receives the value of the touch pen color table (step S27), and turns on the full color LED with a 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 an 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 values in the touch pen state table (step S32), and ends.
In this way, the color of the touch pen 20 is set.

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

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

  If it is determined in step S45 that the pen point 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 current color of the touch pen 20 is read from the touch pen state table (step S47), and a handwritten stroke is drawn with the current color of the 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 in 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 current color of the 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 in 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 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 has left 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 subsequently acquired.

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

  Then, the user is confirmed whether or not to register the current authentication pattern (step S57). If it is confirmed in step S57 that an 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 of the authentication pattern table is restored (step S58), the process returns to step S42, and the authentication pattern is again displayed. Registration process.
