  A mobile terminal device 100 according to the present embodiment will be described with reference to the drawings. Note that the drawings used in the following description are only those necessary for use in the description, and are not limited to these.

  FIG. 1 is a block diagram showing a functional configuration of mobile terminal apparatus 100 according to the present embodiment. The mobile terminal device 100 includes a display unit 101 that is displayed such that a plurality of regions are distinguished from other regions by a numeric keypad, a detection unit 102 that detects a position of a region selected by the user on the display unit 101, and position information And a control unit 104 controlled by a CPU (Central Processing Unit).

  The control unit 104 includes at least a display control unit 104a and a comparison unit 104b. The display control unit 104a causes the display unit 101 to display a plurality of areas such as a partition surrounding a numeric keypad, and changes the display for each area. When the security is released, the comparison unit 104b compares the position information stored in the storage unit 103 in advance by the user with the position information corresponding to the number selected by the user to release the security.

  Next, an operation example of the mobile terminal device 100 will be described in the order of security number registration processing and security release processing. First, the security number registration process will be described with reference to FIGS. FIG. 2 is a flowchart showing an example of the security number registration process of the mobile terminal device according to the present embodiment. FIG. 3 is a diagram illustrating an example of a screen displayed by the mobile terminal device 100 according to the present embodiment. FIG. 4 is a diagram illustrating an internal partition for recognizing position information corresponding to a screen displayed by the mobile terminal device 100 according to the present embodiment. For convenience of explanation, FIG. 1 may be used.

  First, when the detection unit 102 detects an instruction to the display unit 101 by the user, the detection unit 102 notifies the display control unit 104a shown in FIG. 1 of the detection result, and security number registration processing is started (S1, S2).

  The display control unit 104a causes the display unit 101 to display information for allowing the user to select whether the security method is the conventional method or the method of the present invention (S3). Then, the detection unit 102 detects that the method of the present invention has been selected by the user, and notifies the display control unit 104a of the detection result (S4).

  When the display control unit 104a determines that the method of the present invention has been selected (S5), the display unit 101a displays a numeric keypad as shown in FIG. 3 on the display unit 101 (S6).

  Here, the area 101a in which the numeric keypad shown in FIG. 3 is displayed is recognized by the display control unit 104a as an area in which 12 characters from alphabets a to l as shown in FIG. 4 are displayed. That is, the diagram shown in FIG. 4 corresponds to the diagram shown in FIG. 3, and alphabets a to l shown in FIG. 4 are position information of each of the areas 101a where the numeric keypad shown in FIG. 3 is displayed. Note that the diagram shown in FIG. 4 is not displayed on the display unit 101.

  When detecting that “8” displayed on the display unit 101 is selected by the user, the detecting unit 102 notifies the display control unit 104a of the detection result (S7, S8). Based on the diagram shown in FIG. 4, the display control unit 104a recognizes that “h”, which is the position information of the area 101a in which “8” of the display unit 101 is displayed, is selected by the user (S9).

  Similarly, when the detection unit 102 detects that “5”, “1”, and “1” are selected, the detection unit 102 notifies the display control unit 104a of the detection result. The display control unit 104a that has received the notification recognizes that “e”, “a”, and “a”, which are position information corresponding to the respective positions, are selected by the user (S10 to S15).

  When the detection unit 102 detects that the “decision” button shown in FIG. 3 is selected by the user (S16), the detection unit 102 notifies the display control unit 104a of the detection result. The display control unit 104a stores the four pieces of position information “h”, “e”, “a”, and “a” in the storage unit 103 (S17).

  After storing the position information in the storage unit 103, the display control unit 104a causes the display unit 101 to display a security number registration completion notification (S18). Finally, the user recognizes the registration of the security number, and the process ends (S19).

  Next, the security release process will be described with reference to FIGS. FIG. 5 is a flowchart showing an example of the security release processing of the mobile terminal device 100 according to the present embodiment. FIG. 6 is a diagram illustrating an example of a screen displayed during the security release process of the mobile terminal device 100 according to the present embodiment. For convenience of explanation, FIGS. 1 and 4 may be used.

  First, when the detection unit 102 detects that the user has touched the display unit 101, the detection unit 102 notifies the display control unit 104a shown in FIG. 1 of the detection result, and security number release processing is started (S21, S22).

  The display control unit 104a displays the numeric keypad on the display unit 101 (S23). When detecting that “8” shown in FIG. 6A is pressed by the user, the detection unit 102 notifies the display control unit 104a of the detection result (S24). The display control unit 104a (terminal) recognizes that “h”, which is position information corresponding to the position “8” of the display unit 101, is selected by the user based on the diagram shown in FIG. 4 (S25).

  The display control unit 104a determines whether or not a notification of a detection result indicating that the “determine” key has been pressed by the user has been received (S26). If the notification of the detection result has not been received (S26, no), the display control unit 104a randomly changes the numeric layout of the numeric keypad as shown in FIG. 6B (S27), and displays the changed numeric keypad on the display unit 101. (S23).

  S23 to S27 are repeated until the display control unit 104a recognizes that the “determine” key has been pressed by the user. Specifically, the user selects “1” from the numeric keys after the numeric array change shown in FIG. 6B, and “10” from the numeric keys whose numeric arrangement is changed as shown in FIG. 3 ”is selected, and then“ 1 ”is selected from the numeric keypad with the numerical array changed as shown in FIG. Accordingly, the display control unit 104a (terminal) selects “e”, “a”, and “a”, which are position information corresponding to each numeric keypad, based on the diagram shown in FIG. Recognize as

  When the user determines that the input of the security number has not been completed (S28, no), the user returns to S24 and selects one of the numeric keys as described above. On the other hand, when it is determined that the input of the security number is finished (S28, yes), the “determine” key shown in FIG. When detecting that the “decision” key has been pressed, the detection unit 102 notifies the comparison unit 104b shown in FIG. 1 of the detection result (S29).

  When receiving the notification of the detection result (S26, yes), the comparison unit 104b reads the position information stored in the storage unit 103 (S30). The comparison unit 104b compares the position information obtained from the detection result of the detection unit 102 with the position information stored in the storage unit 103 (S31).

  When the comparison unit 104b determines that the pieces of positional information match (S31, yes), the comparison unit 104b notifies the display control unit 104a of the determination result that the release has been successful (S32). The display control unit 104a displays “unlock” on the display unit 101 as shown in FIG. 6F (S34). On the other hand, when the comparison unit 104b determines that the pieces of position information do not match (S31, no), the comparison unit 104b notifies the display control unit 104a of the determination result that the release has failed (S33). The display control unit 104a displays “Release failure” on the display unit 101 (S34).

  When the user recognizes that the release is successful (S35, yes), the security release process is terminated (S37). When it is determined that the release has failed (S35, no), it is determined whether or not to make a security release request again (S36). If requested (S36, yes), the process returns to S24. If not requested (S36, no), the security release processing is terminated (S37).

  As described above, the mobile terminal device 100 according to the present embodiment recognizes the position where the user has pressed the display unit 101. For this reason, for example, even if the security key is a combination of letters and numbers, there is no need to press the button multiple times to convert it to letters, and security can be released easily. Is excellent in operability. Further, when the security is released, the arrangement of the numeric keys displayed on the display unit 101 is randomly changed. For this reason, even if a third party memorizes the numeric keypad number pressed by the user when registering the security number, the security is not released by that number, realizing stronger security than before. can do.

  Specifically, when a user registers a security number, a third party who maliciously memorizes the user's input (“8”, “5”, “1”, “1”) is shown in FIGS. Enter “8”, “5”, “1”, “1” on the screen shown in FIG. Then, since the display control unit 104a recognizes that “h”, “d”, “l”, and “a” are selected, the security cannot be released.

  In the present embodiment, the detection unit 102 detects the position for each region 101a where the numeric keypad shown in FIG. 3 is displayed, but the number of regions displayed on the display unit 101 is three or more. The area information is reset by dividing it into two or more areas including one or more of these areas, and the position of the area designated by the user operation is detected from the reset areas. May be.

  Specifically, for example, the numeric keypad shown in FIG. 3 is used to display an area where “1”, “2” and “3” are displayed, an area where “4”, “5” and “6” are displayed, “ The area is reset to four areas: an area displaying “7”, “8”, and “9” and an area displaying “*”, “0”, and “#”. Then, the position information of each area after resetting is set to “a”, “b”, “c”, and “d”, respectively.

  When the area is reset as described above, for example, when the user selects “8”, “5”, “1”, “1” on the screen illustrated in FIG. 3, the display control unit 104 a displays “c”, “b”. , “A”, “a” are recognized as being selected by the user. Therefore, as in this embodiment, even if a third party remembers the number of the numeric keypad pressed by the user, the security is not released by the number, and stronger security than before can be realized. it can. Further, since the configuration of the internal partition shown in FIG. 4 is simplified, the processing speed can be improved.

  Further, in the present embodiment, the numeric layout of the numeric keypad is fixed during the security number registration process, but the numeric layout of the numeric keypad may be changed also during the security number registration process. Since the position of the numeric keypad pressed by the user is registered in the mobile terminal device 100, the user can press the desired position from the area 101a where the numeric keypad is displayed even if the layout of the numeric keypad is changed. Security numbers can be registered. For this reason, even if a third party remembers the number of the numeric keypad pressed by the user, security is not released by the number, so that stronger security than before can be realized.

  In this embodiment, the alphabet arrangement is fixed and the numeric arrangement is changed randomly, but the reverse is also possible, and the alphabet arrangement is fixed and the alphabet arrangement is changed randomly, and the alphabet is input when registering or canceling. By doing so, it may be recognized that a number has been selected.

  Further, in the present embodiment, the numeric array of the numeric keypad is changed as shown in FIG. 6, but the background of the area where the numeric keypad is displayed is colored to change the color visually to other areas. You may distinguish. By changing the numeric keypad and color randomly, stronger security can be realized. In the present embodiment, four pieces of position information are used, but the number is not limited to this number.

  Further, in the present embodiment, the mobile terminal device 100 having a touch panel on which the numeric keypad is displayed on the display unit 101 has been described. However, the present invention can also be applied to a mobile terminal device having a separate numeric keypad without having a touch panel function. . That is, even the portable terminal device capable of displaying on the display unit 101 the numeric keys different from the numeric keypad arrangement by the display control unit 104a can achieve the same effects as the portable terminal device 100 according to the present embodiment. it can.
