In Patent Document 2, identification information is displayed in a matrix on a display screen such as a touch panel, and a password registered in advance by a user selecting a row or column of the displayed identification information a plurality of times. Is disclosed.

  However, in the technique of Patent Document 1, although the number arrangement at the time of inputting the password is randomly changed, the number of digits of the password is easily specified from the user's operation. In the technique of Patent Document 2, the user needs to touch a row or a column a plurality of times when inputting a password, and the operability is not good.

  Therefore, as a technology that can suppress the identification of the number of digits of the personal identification number and allows the user to easily input a password, Patent Document 3 discloses a password input by the user by a series of inputs, and the user touches the touch panel. A technique is disclosed in which the operation trajectory is compared with a predetermined operation pattern, and the lock is released when the two match.

<First Embodiment>
A first embodiment of the present invention will be described. FIG. 1 shows a block diagram of the information input apparatus according to this embodiment. In FIG. 1, the information input device 10 includes a touch panel 20, a screen information generation unit 30, and an input information determination unit 40. Information input device 10 is applied to a terminal into which a predetermined character string is inputted from a touch panel, such as a smartphone, a tablet terminal, and an automatic teller machine.

  The touch panel 20 displays various information, detects that the user has touched the touch panel 20 with a finger or a stylus pen, and compares the display content displayed on the touch panel 20 with the touched position. Accepts various inputs from the user.

  The screen information generating means 30 extracts all the characters constituting a predetermined character string, arranges them at random, and generates an input information recognition screen by setting a predetermined recognition area for each character. FIG. 2 shows an example of the input information recognition screen generated by the screen information generating means 30 when the predetermined character string is “ABCD”.

  The input information determination unit 40 analyzes the input made on the touch panel 20 when the user makes any input to the touch panel 20 while the input information recognition screen is displayed on the touch panel 20. On the input information recognition screen, the input information determination unit 40 according to the present embodiment continues to enter a predetermined recognition area (hereinafter referred to as IN) and exit (hereinafter referred to as OUT). If this is done, it is determined that the character associated with this recognition area has been designated. On the other hand, the input information determination means 40 does not consider the input locus to the touch panel 20 by the user in the outer region other than the recognition area. Then, the input information determination unit 40 determines that the predetermined character string has been input when the designated character array matches the predetermined character string.

  FIG. 3 shows an example of the input locus when the user inputs “ABCD” using the input information recognition screen shown in FIG. In FIG. 3, the input information determination unit 40 monitors whether “IN-OUT” has been performed as a series of operations in the recognition area. When “IN-OUT” is performed as a series of operations, it is recognized that a character corresponding to the recognition area has been input.

  On the other hand, the input information determination unit 40 does not consider the input trajectory in the outer region other than the recognition area. For example, as shown in FIG. 3, even when the user continuously touches the touch panel 20 between “BC” (solid line) or when the touch on the touch panel 200 is interrupted, the input trajectory is meandering. Even in the case (dotted line), the determination of the input information determination means 40 is not affected.

  Since the user inputs a predetermined character string by line input that passes through the recognition area, it is possible to suppress the number of characters constituting the predetermined character string from being specified by a third party. Furthermore, since the input trajectory in the outer region other than the recognition area is not considered for character recognition, the user is not required to perform a strict input operation.

  Therefore, the information input device 10 according to the present embodiment can suppress the specification of the number of digits of the predetermined character string and can determine the information input device 10 and the input information determination without requiring a strict input operation from the user. Can provide a method.

<Second Embodiment>
A second embodiment will be described. This embodiment demonstrates the information input device which mounts touchscreens, such as a smart phone and a tablet terminal. Accordingly, the information input device may include a microphone, a speaker, an antenna, and the like for realizing general functions such as a call function and a browser function, but in the following, the information input device is locked by inputting a password using a touch panel. The function to be canceled will be described.

  FIG. 4 shows a block diagram of the information input device according to this embodiment. In FIG. 4, the information input device 100 includes a touch panel 200, a password analysis unit 300, and a lock control unit 400.

  The touch panel 200 displays various information, detects that the user has touched the touch panel 200 with a finger or a stylus pen, and compares the display content displayed on the touch panel 200 with the touched position. Accepts various inputs from the user.

  The password analysis unit 300 displays a password input screen on the touch panel 200 when the user performs any operation while the information input device 100 is locked. Then, when the user makes any input on the displayed password input screen, it is determined whether or not the input content matches the password registered in advance. If the input content matches the password, the lock control unit 400 is instructed to release the lock. The password analysis unit 300 will be described later.

  The lock control unit 400 locks the information input device 100 when the user performs an operation for locking the information input device 100 or when the user does not operate the information input device 100 for a certain period of time. The lock control unit 400 unlocks the information input device 100 when the password analysis unit 300 instructs unlocking in a state where the information input device 100 is locked.

  The password analysis unit 300 will be described in detail. As shown in FIG. 4, the password analysis unit 300 includes a password registration unit 310, a password input screen generation unit 320, and a password determination unit 330.

  In the password registration unit 310, a password designated in advance by the user is registered.

  When the user performs any operation while the information input device 100 is locked, the password input screen generation unit 320 includes all characters constituting the password and randomly arranges a plurality of different characters. A character pattern is generated. The password input screen generation unit 320 generates a different character pattern each time a new unlock is performed. The password input screen generation unit 320 further generates a password input screen by setting a predetermined recognition area for each character constituting the character pattern, and displays the generated password input screen on the touch panel 200.

  Here, the recognition area is set to a size that can sufficiently separate the recognition areas of adjacent characters. The user can also specify the size of the recognition area as “large”, “medium”, “small”, or the like. FIG. 5A shows an example of the password input screen when the size of the recognition area is set to “large”, and FIG. 5B shows an example of the password input screen when the size of the recognition area is set to “small”. By setting the size of the recognition area to “large”, it becomes easier to visually recognize and to easily specify characters. On the other hand, by setting the size of the recognition area to “small”, it is possible to reduce erroneously inputting the adjacent character.

  When the password is input on the touch panel 200 while the password input screen is displayed on the touch panel 200, the password determination unit 330 analyzes the input made on the touch panel 200. When the user input matches the password registered in the password registration unit 310, the lock control unit 400 is instructed to unlock.

  Here, the password determination unit 330 according to the present embodiment enters the recognition area set by the password input screen generation unit 320 (hereinafter referred to as IN) and exits from the recognition area (hereinafter referred to as OUT). ) Is performed through a series of inputs, it is determined that the character associated with the recognition area has been input. For example, when a recognition area corresponding to “h” is displayed on the touch panel 200, the user has passed through the recognition area continuously with a finger, a stylus pen, or the like, as indicated by an arrow α in FIG. In this case, the password determination unit 330 determines that “h” is input by the user. On the other hand, in FIG. 6B, after entering from the outer area of the recognition area to the inner area (arrow β), after temporarily interrupting the touch panel 200, the user exits from the inner area of the recognition area to the outer area. (Arrow γ), the password determination unit 330 does not recognize the character input.

  An operation procedure for displaying the password input screen and an operation procedure for unlocking the information input device 100 configured as described above will be described. The operation flow of the information input device 100 at this time is shown in FIG.

  When the user performs any operation while the information input device 100 is locked (S101), the password input screen generation unit 320 reads the password from the password registration unit 310 (S102), and the characters constituting the password A predetermined number of characters different from each other are selected. And the password input screen production | generation part 320 produces | generates a character pattern by arrange | positioning the selected character at random (S103). Furthermore, the password input screen generation unit 320 generates a password input screen by setting a recognition area for each character, and displays the generated password input screen on the touch panel 200 (S104).

  For example, when “hsrkks” is registered as a password in the password registration unit 310, the password input screen generation unit 320 selects a predetermined number of characters including “h”, “s”, “r”, and “k”. Generate character patterns by arranging them randomly. Then, in the generated character pattern, a recognition area is set for each character to generate a password input screen. For example, the password input screen generation unit 320 displays the password input screen illustrated in FIG. 5 on the touch panel 200 as the password input screen. In FIG. 5, the password input screen includes characters “h”, “s”, “r”, “k” that are used for the password, and characters “m”, “j”, “a”, “” that are not used. d ”and“ x ”are randomly arranged, and a recognition area is set for each character.

  Then, after the password input screen is displayed on the touch panel 200, when the user inputs something to the touch panel 200 with a finger, a stylus pen, or the like, the password determination unit 330 detects it. The password determination unit 330 determines that a character corresponding to the recognition area has been input when IN and OUT are continuously performed on the predetermined recognition area. When the input operation by the user sequentially passes through the recognition area, and the input character string matches the password registered in the password registration unit 310 (YES in S105), the password determination unit 330 The lock control unit 400 is instructed to release the lock, and the lock is released (S106).

  Here, FIG. 8 shows an example of a locus by a finger, a stylus pen, or the like when the user inputs the password “hsrkks” using the password input screen shown in FIG. As shown in FIG. 8, the password determination unit 330 allows the user to continuously perform IN and OUT to each recognition area in the order of “h”, “s”, “r”, “k”, “k”, and “s”. Instructs the lock control unit 400 to release the lock. As shown in FIG. 8, when determining whether or not a corresponding character is input based on whether or not IN and OUT are continuously performed on the recognition area, the same character is transmitted by passing through the outer region. Input can be performed continuously.

  Note that the user's input operation in the area outside the recognition area does not affect the operation of the password determination unit 330. For example, in FIG. 8, when touching the touch panel 200 along the solid line at the shortest distance between points A and B after leaving the recognition area “h”, the touch to the touch panel 200 is performed at the point A. After the interruption, the password determination unit 330 operates in the same manner when the contact with the touch panel 200 is started again at the point B or when the input locus meanders like a dotted line.

  As described above, in the information input device 100 according to the present embodiment, since the user inputs a password by line input that passes through the recognition area, the number of characters constituting the password is specified by a third party. This can be suppressed. Furthermore, since the input trajectory in the outer area other than the recognition area is not considered for password recognition, it is not necessary to request a strict input operation from the user.

  In the present embodiment, the case where the characters constituting the password are alphabets has been described, but the present invention is not limited to this. For example, a password can be configured by numbers, symbols, designs, colors, and the like. Furthermore, in the present embodiment, the character pattern is generated in a matrix type, but the present invention is not limited to this. As an example, FIG. 9A shows a circular character pattern (password input screen), and FIG. 9B shows a character pattern (password input screen) when characters are randomly arranged.

<Modification of Second Embodiment>
A modification of the second embodiment will be described. The information input device according to the present embodiment is configured in the same manner as the information input device 100 of FIG. 2 described in the second embodiment. Hereinafter, each element of the information input device 100 according to the second embodiment will be described with “B” attached.

  In this embodiment, when generating a character pattern, the characters constituting the password are arranged adjacent to each other in the order in which the password is formed. That is, a character pattern is generated in which the input locus of the password by the user is a single stroke.

  For example, a case where the registered password is “12357” and the password input screen is configured by nine numbers “1” to “9” will be described as an example. In this case, the password input screen generation unit 320B sets “2” around “1” and “2” around “2” for “1”, “2”, “3”, “5”, and “7” constituting the password. 3 ”is arranged so that“ 5 ”is positioned around“ 3 ”and“ 7 ”is positioned around“ 5 ”. Furthermore, the password input screen generation unit 320B generates a character pattern by randomly arranging the remaining “4”, “6”, “8”, and “9” in an empty position, and sets a recognition area for each character. The password input screen is generated by

  FIGS. 10A, 10B, and 10C show examples of the password input screen generated by the password input screen generation unit 320B and the user input trajectory for the generated password input screen.

  As shown in FIGS. 10A, 10 </ b> B, and 10 </ b> C, the user can input the password by tracing the password sequentially with a finger, a stylus pen, or the like.

  Here, every time the information input device 100 is locked, the password input screen generation unit 320 generates a password input screen with a different character pattern, so that the user inputs a password with a different input path each time the lock is released. Although it is necessary, since the characters constituting the password are arranged adjacent to each other, the user can easily find the character to be input next, and can input the password smoothly in the manner of one stroke writing.

  Also in the present embodiment, since it is determined whether or not the corresponding character is input based on whether or not IN and OUT to the recognition area are continuously performed, the dotted line is shown in FIG. As described above, even when the user's input trajectory is different from the standard trajectory in the outer area of the recognition area or when the touch to the touch panel 200B is temporarily interrupted in the outer area of the recognition area, the password determination unit 330B Recognize password input by.

  As described above, when the information input device 100B according to the present embodiment generates a character pattern, the characters constituting the password are adjacently arranged in the order of constituting the password. In this case, the user can easily find the character to be input next, and can input the password smoothly in the manner of one-stroke writing.

  The information input devices 10, 100, and 100B described in the above embodiment can be applied to a device that needs to perform user authentication as a security measure. Specifically, the present invention can be applied to portable terminals such as smartphones and tablets equipped with touch panels, fixed terminals such as personal computers and ATMs, safe doors, and security area entry / exit devices.

  The present invention is not limited to the above-described embodiment, and design changes and the like within a range not departing from the gist of the present invention are included in the present invention.
