PROBLEM TO BE SOLVED: To improve crime prevention property and operability.SOLUTION: A user authentication device 1 includes: display means 2 for displaying identification information like a matrix on a display surface: selection means 3 for selecting at least one of a plurality of lines and columns in matrix information on the display surface on the basis of the inclination direction of the display surface and input information corresponding to the plurality of lines and columns in the matrix information on the display surface; and control means 4 for performing user authentication by collating a plurality of identification information included in at least one of the plurality of lines and columns in the matrix information selected by the selection means 3 with predetermined recognition information.

Description

  The present invention relates to a user authentication device, a user authentication method, and a user authentication program that can perform user authentication while improving crime prevention and operability.

  When logging in with a terminal or the like, a device for inputting a preset user name and password is known (for example, see Patent Document 1). In this case, when an input operation is directly peeked at the time of input, a password or the like is easily guessed by observing the display screen or user operation. On the other hand, a long password setting and a complicated password setting combining a plurality of types of characters are conceivable, but it is not practical in terms of operability because it is difficult for a user to remember and requires an input time.

Japanese Patent Laid-Open No. 7-129512 JP 2006-277334 A Japanese Patent No. 4317359

  By the way, for example, when logging in to a mobile terminal, a technique is known in which a multi-digit password consisting of numbers 0 to 9 is input using a touch panel. This password is generally input with four or more digits. In this case as well, when the screen display or the user operation is looked at in the same manner as described above, the problem of crime prevention that the password is easy to guess arises.

  To solve this problem, a technique is known in which the numeric keypad layout displayed on the screen is replaced and a pattern different from the normal layout is displayed (see, for example, Patent Document 2). However, it is hard to say that it is sufficient from the viewpoint of crime prevention when it is directly peeped or when there is anxiety that it may be peeped.

  Furthermore, in the input of pattern authentication, authentication is generally performed by inputting along a preset position or order using elements such as figures, symbols, images, colors, and character types. In this case, since the pattern is determined, it is easy to guess when peeped. Furthermore, there is a crime prevention problem that the input information is easily guessed from fingerprint marks in a device using a touch panel.

  In matrix authentication input, a method of inputting numbers and character strings in a table corresponding to a position and order set in advance by a user is generally known from a grid-like table (for example, (See Patent Document 3). It is a one-time password method based on numbers or character strings that change randomly each time, and has high security. On the other hand, since the password is random each time, the user is required to input the table by comparing the table each time, which causes a problem in terms of operability. Furthermore, in order to improve security for peeping, it is necessary to make it difficult to know from which position the input character is cited. As a solution to this problem, the number of matrixes in the table is generally increased and the same numerical values and character strings are included in the table to avoid this problem. However, as the number of tables increases, there is a problem that a screen display area is required.

  The present invention has been made to solve such problems, and a main object of the present invention is to provide a user authentication device, a user authentication method, and a user authentication program with improved crime prevention and operability. .

In order to achieve the above object, one embodiment of the present invention provides:

According to the user authentication device 1 according to the present embodiment, at least one of a plurality of rows and columns in matrix information is selected, a plurality of identification information included in the selected rows and columns, predetermined recognition information, , Match. Thereby, crime prevention property and operativity can be improved.

  FIG. 2 is a block diagram showing a schematic system configuration of the user authentication apparatus according to the embodiment of the present invention. The user authentication device 10 according to the present embodiment is mounted on a mobile terminal such as a mobile phone or a smartphone, for example, and can improve crime prevention and operability with respect to user authentication on the mobile terminal.

  The user authentication device 10 includes an input unit 11, a random number generation unit 12, a control unit 13, a display unit 14, a user input storage unit 15, a password storage unit 16, and an inclination sensor 17.

The input unit 11 is a specific example of a selection unit, and has a function in which a user performs an input operation on a display screen or the like and inputs input information corresponding to the input operation. The input unit 11 includes an arbitrary input device such as a touch panel incorporated in the display unit 14 of the mobile terminal. The user can input arbitrary information such as a user ID and password information into the input unit 11. The input unit 11 outputs password information based on the tilt direction of the mobile terminal and the input information by the user's input operation to the control unit 13.
The tilt sensor 17 is built in the mobile terminal and can detect the tilt direction of the display screen of the mobile terminal. The tilt sensor 17 is connected to the input unit 11 and outputs information on the tilt direction of the mobile terminal to the input unit 11.

  The control unit 13 is a specific example of a control unit, and performs user authentication by collating password information output from the input unit 11 and regular password information stored in the password storage unit 16, for example. The control unit 13 includes, for example, a CPU (Central Processing Unit) that performs control processing, arithmetic processing, and the like, a ROM (Read Only Memory) that stores a control program executed by the CPU, an arithmetic program, processing data, and the like. The microcomputer is composed mainly of a microcomputer composed of a RAM (Random Access Memory) or the like for temporary storage. The CPU, ROM, and RAM are connected to each other via a data bus or the like.

  The display unit 14 is a specific example of display means, and displays arbitrary information such as graphics, characters, and images on the display screen. The display unit 14 is configured by, for example, a liquid crystal display device, an organic or inorganic EL display device.

  The display unit 14 displays, for example, a plurality of password identification elements that can be recognized as passwords in a matrix on the display screen. Then, the input unit 11 inputs password identification elements on the row and column selected in the matrix information on the display screen as input information.

  For example, matrix information 311 as shown in FIG. 3 is displayed on the display screen of the display unit 14. The user selects, for example, row (1), row (2), and column (3) via the input unit 11. The input unit 11 includes a password identification element (1582) corresponding to the selected row (1), a password identification element (8019) corresponding to the row (2), and a password identification element (1078) corresponding to the column (3). And password information (1582 8019 1078) that is a combination of the above and the like. As described above, the user can input password information having a high digit of multiple digits by simply selecting a row and a column of the matrix information. Note that the user may select only one of the rows and columns of the matrix information via the input unit 11. The number of rows and columns of matrix information selected via the input unit 11 may be arbitrary.

  The user input storage unit 15 is a specific example of the first storage unit, and temporarily stores password information output from the input unit 11. The user input storage unit 15 stores, for example, password information output from the input unit 11 in the user selection password table 151 via the control unit 13. The user selection password table 151 stores the row and column selected by the user, the directionality, and the password identification element constant included in the selected row and column. The control unit 13 acquires password information from the user selection password table 151 of the user input storage unit 15 and performs the user authentication.

  The user input storage unit 15 and the password storage unit 16 are configured with, for example, a magnetic disk device, an optical disk device, a RAM, and the like. The user input storage unit 15 may be configured to be built in the control unit 13.

  The password storage unit 16 is a specific example of the second storage unit, and stores a password identification element table 161, a password registration table 162, and a password output table 163. The password identification element table 161 stores password identification elements for identifying passwords such as numerical values, graphics, colors, images, and characters. The password registration table 162 stores regular password information for each user. The password output table 163 stores arrangement pattern information when the password identification elements are arranged in a matrix.

  The display unit 14 displays the password identification elements in a matrix on the display screen based on the array pattern information of the password output table 163 of the password storage unit 16. The user input storage unit 15 and the password storage unit 16 are configured separately, but are not limited thereto, and may be configured integrally.

  The control unit 13 displays the password identification elements of the password identification element table 161 on the display screen of the display unit 14 in accordance with the arrangement pattern information of the password output table 163 stored in the password storage unit 16. The user inputs password information by selecting a password identification element on the display screen of the display unit 14 via the input unit 11.

  The random number generation unit 12 is a specific example of random number generation means, and has a function of randomly changing the array pattern of password identification elements in the password output table 163 of the password storage unit 16.

Next, the password information input method will be described more specifically with reference to FIG.
As shown in FIG. 4, 4 × 4 matrix information composed of rows 1, 2, 3, 4 and columns A, B, C, and D is displayed on the display screen of the display unit 14. In each row and column, four preset password identification elements 411 are arranged.

  For example, when the user rotates the display screen of the mobile terminal about the Y axis (inclined in the row direction in which each row of matrix information extends), the input unit 11 detects the display screen of the mobile terminal detected by the tilt sensor 17. Based on the inclination direction, each row (1 to 4) of the matrix information is selected. As a result, each row (1 to 4) of the matrix information is selected, but at this time, it is not determined which row is selected. Therefore, the user further performs an input operation (such as a tap operation) and selects one of the password identification elements 411 in the row to be selected in the matrix information on the display screen. For example, if row 4 is to be selected, one of Δ, ○, ◎, and ◇ arranged in row 4 may be selected. Thereby, the input unit 11 specifies the matrix information based on the inclination information in the row direction of the display screen of the mobile terminal detected by the inclination sensor 17 and the input information (any password identification element) by the user. Can be recognized.

  On the other hand, when the user rotates the display screen of the mobile terminal about the X axis (tilt in the column direction in which each column of matrix information extends), the input unit 11 detects the display screen of the mobile terminal detected by the tilt sensor 17. Each column (A to D) of the matrix information is selected on the basis of the inclination direction. As a result, each column (A to D) of the matrix information is selected, but at this point, it is not determined which column is selected. Therefore, the user further selects and selects one of the password identification elements 411 in the column to be selected in the matrix information on the display screen. For example, when it is desired to select the column D, one of □, ◎, ☆, and ◇ arranged in the column D may be selected. Thus, the input unit 11 specifies the matrix information based on the column direction inclination information of the display screen of the mobile terminal detected by the inclination sensor 17 and the input information (any password identification element) by the user. Columns (A to D) can be recognized.

  Note that it is not possible for a third party to select each column of matrix information by tilting the mobile terminal in the column direction, or to select each row of matrix information by tilting the mobile terminal in the row direction. . Furthermore, the act of specifying each column and each row itself is difficult to read because it merely selects an arbitrary password identification element. For this reason, crime prevention can be improved significantly. Further, as described above, since the input act itself includes an act of tilting the display screen of the mobile terminal, the selection of the password identification element itself is less likely to be seen in spite of peeping from a certain direction. Can also be expected to improve the crime prevention. If there is only the user himself / herself on the spot and is unlikely to be seen by a third party, the selected password identification element can be used as the final password identification element as it is. Can be improved.

  Next, a method for the user to register password information will be described in detail. 5A and 5B are flowcharts showing a processing flow when the user registers password information.

  In (step S <b> 511), first, the user sets a password identification element used for a password in the control unit 13 via the input unit 11. The password identification element 411 includes, for example, numerical values (0, 1, 2,...), Figures (circle, triangle, square, etc.), colors (red, blue, green, etc.), character types (a, A, ah, 2, # Etc.), etc., etc., are information preset in the system program. The password identification element 411 may use an image (photograph or illustration) that can be arbitrarily registered by the user.

  In (step S512), the number of rows and columns of matrix information is set in the control unit 13 via the input unit (one specific example of changing means) 11 as shown in FIG. Note that the user can arbitrarily set and change the number of rows and columns of matrix information via the input unit 11. For example, in FIG. 4, matrix information of 4 rows and 4 columns is illustrated.

  In this (step S512), the number of rows and columns to be displayed is determined, and the number of intersections, that is, the number of password identification elements 411 displayed on the password release screen is determined. In FIG. 4, 16 password identification elements 411 of 4 rows and 4 columns (4 × 4) are displayed.

  In (step S 513), the control unit 13 generates a password identification element table 161 based on the password identification element 411 input from the input unit 11 and stores the password identification element table 161 in the password storage unit 16. The password identification element table 161 is a table for registering password identification elements as shown in FIG. 7, for example. As shown in FIG. 7, a password identification element constant 711 is set for each password identification element 411, such as s1 when the password identification element 411 selected by the user is a figure ◯, and s2 when the figure △. .

  In (step S514), the number of digits of the password, that is, the number of digits entered when the user cancels the password is set in the control unit 13 via the input unit 11. For example, as illustrated in FIGS. 8A and 8B, the control unit 13 generates a registered password constant 811 representing the number of password digits to be registered. The registered password constant 811 varies depending on the number of password digits. For example, the control unit 13 creates a table of k1 to kL (four digits in the example of FIG. 8, up to k4), and each registered password constant 811 has a password identification element 411 (password identification element constant 711) that is a regular password. Register.

  In (step S515), the presence or absence of a direction option rule for setting the direction of the selection method of the password identification element 411 is set in the control unit 13 via the input unit 11.

  When there is no directionality option rule, for example, when selecting the k1 password identification element 411, it may be selected by row or column, but when there is a directionality option, the k1 password identification element When selecting 411, it is specified whether to select by row or by column. By selecting “With directionality option”, the security of the password can be improved.

In (step S516), user password selection and registration are started.
When determining that the directionality option rule is not set in the above (Step S515) (NO in Step S517), the control unit 13 determines the password identification element Kx based on the input information by the user, and increments the variable x. (Step S524). When it is determined that the number of password digits x = L designated by the user has been reached (YES in step S525), the control unit 13 proceeds to the following process (step S523). .

  On the other hand, when it is determined that the directionality option rule is set in (Step S515) (YES in Step S517), the control unit 13 determines the direction Kx of the directionality option based on the input information by the user. (Step S518). The control unit 13 determines the password identification element Kx based on information input by the user, and increments x (step S519). When the control unit 13 repeats the processes of (Step S518) and (Step S519) and determines that the password digit number x = L specified by the user has been reached (YES in Step S522), the following (Step S523) Move on to processing.

In (step S523), the control unit 13 displays the password on the display unit 14, and the user confirms the password.
In (step S527), the display unit 14 displays a confirmation screen and requests user approval. When the user approves on the confirmation screen of the display unit 14, in (step S528), the control unit 13 sets the password identification element 411 and the direction in k1 to kL of the password registration table shown in FIG. 8B created in (step S514). Set the additional option 813 of property (column / row).

  On the other hand, if the user does not approve on the confirmation screen of the display unit 14, the process returns to the above (step S516), and the user re-enters the password.

  In (Step S529), the display unit 14 displays a display screen as shown in FIG. 4, and the user confirms the actual operation.

  Next, the operation confirmation and password release processing in the above (step S529) will be described in detail. 6A and 6B are flowcharts illustrating an example of the operation check process and the password release process.

  In (step S611), the display unit 14 changes the display screen to a display screen for logging in to the system. The display unit 14 transitions the display screen to, for example, a screen for setting the mobile terminal in a power-on state or a sleep release state, or a screen for logging in to the mobile terminal.

  In (Step S612), the random number generation unit 12 uses an array of password identification elements 411 as shown in FIG. 9 in the password output table 163 in which all password identification elements 411 are registered from the password identification element table 161 of the password storage unit 16. Change the pattern randomly. For example, row 1 column A is ☆ s5 and row 4 column C is ◎ s14.

  In (Step S613), the display unit 14 generates and displays a lock release screen as shown in FIG. 4 based on the password output table 163 shown in FIG. 9, for example.

  In (Step S614), the control unit 13 creates the user-selected password constant 1011 (u1 to uL) in the user-selected password table 151 shown in FIG. 10, and the direction 1012 selected by the user and the identification element selected by the user A table is created that records 1013, the row and column 1014 selected by the user specified by the two, and the password identification element constant 1015 included in the column and row.

  In (Step S615), the control unit 13 sets an initial value x = 0 in ux in the user-selected password table 151, and in (Step S616), the control unit 13 performs an increment process to set x of ux from the current value to +1. Do.

  In (step S617), the user tilts the portable terminal in the column direction or the row direction to select one of the column and the row in the matrix information in order to cancel the password lock. Further, in (step S618), the user can select any password included in the row or column including the password identification element 411 of the regular password kx in the x-th digit (the value of x is always the same as Ux) for unlocking the password. The identification element 411 is selected via the input unit 11.

  In (step S619), the control unit 13 saves the arbitrarily selected password identification element 411 in the ux of 1013 in FIG. 10, and simultaneously stores the tilt information detected by the tilt sensor 17 in the ux of 1012.

  The control unit 13 specifies the row and column selected by the user from the information of ux 1012 and 1013 and stores the information in the ux 1014.

  The control unit 13 stores the information of the password identification element included in the column or row in the ux 1015 from the ux 1014 information.

  In (step S621), the control unit 13 determines whether or not the input password has reached a preset maximum number of digits (L value of kL). When the control unit 13 determines that the maximum number of digits of the password has not been reached (NO in step S621), the control unit 13 returns to the processing in the above (step S616). Then, +1 is added to the number of password digits x of the password ux input by the user, and the steps from (Step S617) to (Step S619) are repeated.

  On the other hand, when the control unit 13 determines that the maximum number of digits of the password has been reached (YES in step S621), the control unit 13 proceeds to the following process (step S622).

  In (step S622), the control unit 13 determines whether or not kx of the password registration table 162 that is a regular password is included in the password identification element 1015 in ux of the user selection password table 151 that is a password selected by the user. Determine.

  When the control unit 13 determines that kx of the password registration table 162 is not included in the ux password identification element of the user-selected password table 151 (NO in step S622), the display unit 14 displays a message that the passwords do not match. Is displayed (step S625). Then, the control unit 13 returns to the above process (step S612) and starts the password release process again.

  If the control unit 13 determines that kx of the password registration table 162 is included in the ux password identification element of the user-selected password table 151 (YES in step S622), whether or not a direction option rule is set Is determined (step S623).

  When it is determined that the directionality option rule is not set (NO in step S623), the control unit 13 releases the lock (step S626). On the other hand, if the control unit 13 determines that the directionality option rule is set (YES in step S623), the directionality 1012 of the selected row or column in the user selection password table 151 and the password registration that is a regular password are registered. It is determined whether or not the directivity 813 of the table 162 matches (step S624).

  When it determines with the said match (YES of step S624), the control part 13 performs lock release (step S626). On the other hand, when it determines with the said control part 13 not being in agreement (NO of step S624), it returns to the said (step S625).

  When the control unit 13 succeeds in the unlocking, for example, the user successfully logs in to the mobile terminal or the system, and the mobile terminal or the system shifts to a state where the user operation is possible.

As described above, according to the user authentication device 10 according to the present embodiment, for example, it is possible to reduce the risk of a password leaking even when directly peeped or when it is lost such as a mobile phone and can be operated by others. In addition, the operation by the password input person and the storage of the password become easy.
In particular, in the method of explicitly selecting a row and a column including a password, there arises a problem that a third party can see that the password is selected by the act of selecting the row and the column. On the other hand, even in an environment where there are no people around and passwords cannot be stolen, it is necessary to use the same operation method as usual, and the work remains complicated.
On the other hand, according to the user authentication device 10 according to the present embodiment, as described above, even if a password selection operation is seen by a third party, the contents cannot be understood, so the crime prevention performance is greatly improved. Can be improved. In addition, since the input act itself includes the act of tilting the display screen of the mobile terminal, the secondary effect of making it difficult for the password identification element selection to be easily seen with respect to peeping from a certain direction. Can also be expected, and the crime prevention property is further improved. Furthermore, when there is only the user himself / herself and there is no possibility of being peeped by a third party, the selected password identification element can be used as the final password identification element as it is. Can be improved. That is, the crime prevention property and operability of the user authentication device 10 can be improved.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

  In addition, the present invention can be realized by causing the CPU to execute the computer program for the processes shown in FIGS. 5A and 5B or 6A and 6B.

  The program may be stored using various types of non-transitory computer readable media and supplied to a computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / W and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)) are included.

  The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves.
