Description

  The present invention relates to an authentication device, a user authentication method, a user authentication card, and a storage medium, and more particularly to an authentication device, a user authentication method using the authentication device, a user authentication card, and a storage medium that stores a program for user authentication.

Technical background

  Conventionally, as for security used in a personal computer (referred to as a personal computer or a PC), authentication is generally obtained by inputting a password or a user ID from a keyboard. In this method, the password and user ID defined by the user are kept secret from a third party, and are entered from a screen of a personal computer or the like for authentication and activation or various accesses.

  However, if the password or user ID of the above character string or number string is known to a third party, it is easily broken, so there is a problem in reliability as security.

  In order to solve these problems, the present invention provides a coordinate pattern input on a touch panel or tablet of a device capable of detecting coordinates, such as a device having a tablet or a pen input type personal computer (hereinafter referred to as a pen PC). A card with a key set to authenticate by verifying the coordinate pattern input from the hole or hole of the card, notch or mark and the registered coordinate pattern, etc. The purpose is to carry high-security authentication easily.

  Means for solving the problem will be described with reference to FIG.

  In FIG. 1, a central processing unit (CPU) 1 performs various processes in accordance with a program. Here, the read coordinates are compared with registered coordinates, and authentication is performed based on the comparison results. It is something to do.

  The coordinate detection microcomputer 4 detects coordinates based on signals from the coordinate detector 6 according to a program. Further, the comparison authentication is performed not only by the CPU 1 but also by the authentication based on the result of comparison by the local processing of the coordinate detection microcomputer 4.

  The coordinate detector 6 is for detecting coordinates input on the screen. Here, the screen refers to a screen on which an image is displayed with a CRT or liquid crystal, a screen including a surface for detecting coordinates such as a tablet, and a touch panel provided on a display device. Therefore, the coordinate detector 6 shown in FIG. 1 includes a display unit and an input unit.

  Next, the operation will be described.

  The coordinate detection microcomputer 4 reads (or detects) the coordinates input from the coordinate detector 6, and compares and compares the plurality of coordinates read (or detected) by the CPU 1 with the registered plurality of coordinates. Authentication is performed based on the result.

  At this time, the CPU 1 compares the order of the plurality of coordinates read with the order of the registered coordinates, and performs authentication based on the comparison results.

  In addition, the coordinate detection microcomputer 4 determines that the input of the plurality of coordinates is completed when the average value of the input intervals of the plurality of coordinates read or becomes longer than a predetermined interval.

  A card having a plurality of discontinuous holes or holes, notches or marks placed on the coordinate detector 6 and coordinates input based on the holes, holes, notches or marks are detected by a coordinate detection microcomputer. 4 reads.

  That is, it is only necessary to be able to specify coordinates, and it may be a hole that penetrates the card, or a hollow hole that does not penetrate. The pen PC described later includes a resistance film method, an electrostatic coupling method, an electromagnetic induction method, and the like. For example, the electromagnetic induction method senses the magnetism of the pen (or stylus) by a coordinate detector arranged below the screen. Therefore, even if the pen does not touch the screen directly, it senses magnetism. Therefore, in this case, what is provided in the card does not necessarily have to be a through-hole, but may be a depression or a hole. Moreover, a mark may be sufficient.

  Also, the coordinate detection microcomputer 4 is placed in a designated area on the coordinate detector 6 with a plurality of discontinuous holes or holes, notches or marks, and is input based on the holes, holes, notches or marks. The coordinate is read, the coordinate pattern read by the CPU 1 is compared with the registered coordinate pattern, and authentication is performed based on the comparison result.

  Further, a plurality of discontinuous holes or holes, notches or marks of the card are arbitrarily provided.

  In addition, the designated area on the screen is set to a predetermined area determined by a random number.

  In addition, any one of the four corners of the designated area on the screen is determined by a random number.

  Further, the coordinate detection microcomputer 4 places a card provided with a plurality of discontinuous holes or holes, notches or marks in an arbitrarily moved designated area on the coordinate detector 6 and the holes or holes, notches or marks. The coordinates input based on the above are read, the coordinate pattern read by the CPU 1 is compared with the registered coordinate pattern, and authentication is performed based on the comparison result.

  Further, the coordinate detection microcomputer 4 places a card having a plurality of discontinuous holes or holes, cutouts or marks on a keyboard frame displayed on the coordinate detector 6 so as to have holes, holes, cutouts or marks. The code value corresponding to the non-display key of the keyboard input to is read (output), the code read (output) by the CPU 1 is compared with the registered code, and the authentication is performed based on the comparison result. Like to do. At this time, a user level and an administrator level common to all user levels may be registered for a plurality of coordinates registered by the CPU 1, a registered coordinate pattern, or a registered code value.

  Also, the coordinates detected by the coordinate detection microcomputer 4 provided with a plurality of discontinuous holes or holes, cutouts or marks are placed on the coordinate detector, and the coordinates inputted based on the holes, holes, cutouts or marks. And the coordinate pattern read by the CPU 1 and the pattern determined by the indicated position and the registered pattern based on the position specified by the arbitrary first or arbitrary arbitrary pattern of coordinates. The comparison is performed, and authentication is performed based on the comparison result.

  Arbitrary data input based on the hole, hole, notch, or mark placed on the coordinate detector by the coordinate detection microcomputer 4 provided with a plurality of discontinuous holes, holes, notches, or marks. CPU 1 virtually sets the keyboard at the position indicated by the first one or any plurality of arbitrary numbers, reads the code corresponding to the key at the input position based on the virtually set keyboard. Is compared with the registered code, and authentication is performed based on the comparison result.

  The coordinate detection microcomputer 4 reads a resistance value corresponding to one or a plurality of coordinates input from the resistive film type coordinate detector 6, compares the resistance value read by the CPU 1 with the registered resistance value, Authentication is performed based on the comparison result. Therefore, by verifying the coordinate pattern input from a plurality of discontinuous holes or holes, notches, marks, etc. on the card against the registered coordinate pattern, etc., authentication can be performed using the user's own key. It is possible to improve the security and carry a card with a key set for easy and highly secure authentication.

  FIG. 29 shows an example in which the present invention is applied to a pen PC. Here, by placing a card (or ID card) 34 or the like on the screen 32 of the pen PC 31 and pressing the hole or hole, notch or mark with the pen 33, the transparent placed on the screen 32. In the case of a coordinate detector or electromagnetic induction system, the coordinates are detected by sensing the magnetism from the pen by a non-transparent coordinate detector arranged below the screen 32, and the ID registered as described above. It is possible to perform authentication compared to the above. At this time, a card frame, a position marker indicating the position where the card is placed, and the like are displayed on the screen 32. For example, a card 34 is placed in the card frame, and a hole or hole, a notch or a mark portion is placed with the pen 33. The card frame or soft 10 key may be pressed based on the pressing of the predetermined one or more holes or holes, notches or mark portions of the card 34 without displaying the card frame. A frame or the like may be set virtually. In any case, the pressed coordinates are detected based on the displayed frame or position marker or the virtually set frame or position marker, and authentication is performed by comparing with the registered coordinates.

  If the card (or ID card) 34 has, for example, substantially the same shape and size as a commonly used credit card, it is convenient for carrying.

  FIG. 30 shows an application example of the present invention. A portable pen input type computer 41 as shown in the figure has already been developed. For example, a display unit 42 made of a thin B5 or A4 size liquid crystal display panel is attached. A transparent touch panel (not shown) is attached so as to cover the front surface of the display unit 42, and the touch panel is approached, touched or lightly pressed with the input pen 43, so that the coordinates of the touched position can be detected. Here, the display unit 42 is a liquid crystal display, but the present invention is not limited thereto, and may be a plasma discharge panel or a CRT. Such a pen input computer 41 can have the above-described configuration of FIG. The present invention is applicable not only to the pen input computer 41 but also to various programmable devices having a coordinate detection device such as a word processor, an electronic notebook, a desktop device to which a coordinate detection device is connected, and a cash dispenser.

  The computer input method can be roughly divided into a resistive film method, an electrostatic coupling method, an electromagnetic induction method, and the like, but any input method may be used in the present invention. Furthermore, the present invention may be applied to a touch panel that has no pen input and is touched with a finger.

  As described above, according to the present invention, a configuration is adopted in which authentication is performed by comparing a coordinate pattern input from a hole or notch of a card with a registered coordinate pattern, etc. Can be used to increase the reliability of security and carry a card with a key set for easy high security authentication.

  Next, embodiments and operations of the present invention will be described in detail sequentially with reference to FIGS.

  FIG. 1 shows a system configuration diagram of the present invention.

  In FIG. 1, a CPU 1 performs various processes according to a program. Here, a program read from the CD-ROM 8a by the CD-ROM device 8, a program read from the floppy disk (FD) 9a by the floppy disk (FD) device 9, or a program downloaded from the center via the communication device 7, The data is loaded onto the hard disk of the hard disk device 10 and the CPU 1 reads it and performs various processes described with reference to FIGS.

  The various circuits 2 are various circuits necessary for the CPU 1 to perform various processes. The various circuits 2 include input / output (I / O) control units such as a display control unit and a keyboard (not shown) control unit.

  The system memory 3 and the hard disk of the hard disk device 10 are memories for storing programs and data.

  The coordinate detection microcomputer 4 performs various processes according to a program stored in the flash ROM 5 or the like.

  The flash ROM 5 is a non-volatile memory for storing programs and the like, and is an example of non-volatile memories such as an EEPROM and a mask ROM. Moreover, you may replace with ROM which has a coordinate detection microcomputer inside. Actually, a coordinate input device such as a tablet stores correction data at the time of coordinate detection, that is, correction data representing the characteristics of each tablet in a rewritable nonvolatile memory such as a flash ROM or EEPROM. Since the coordinate detection is corrected using the registration data, the registration data described in the present invention can be stored together and used below.

  The coordinate detector 6 detects an input coordinate value or, in the case of a resistance type, detects a resistance value corresponding to the input coordinate. The coordinate detector 6 detects input coordinate values of a screen displayed on a CRT, a screen displayed on a liquid crystal, a tablet, or the like. In the present invention, the coordinate detector includes those that detect all coordinates such as the screen displayed on the CRT, the screen displayed on the liquid crystal display, the touch panel, the tablet, and the resistance type tablet. . For example, a touch panel in which a thin film resistance type digitizer is arranged on a liquid crystal display or a plasma discharge panel, a touch panel in which an electromagnetic induction type digitizer is arranged under a liquid crystal display or a plasma discharge panel, or the like may be used. In the case of the electromagnetic induction method, coordinates are detected by sensing magnetism from a pen (or stylus) by a coordinate detector disposed below a screen (for example, a liquid crystal display).

  The authentication device according to the present invention includes at least a coordinate detection microcomputer 4, a flash ROM 5 (or memory), and a coordinate detector 6, and can be applied to a personal computer equipped with a pen personal computer or a tablet as a display device. In a preferred embodiment, it is a personal computer having a tablet or touch panel that can be pointed and input directly with a pen or hand on the display screen, such as a portable pen personal computer or electronic notebook.

  The communication device 7 exchanges programs and data with the center. The CD-ROM device 8 reads out a program from the CD-ROM 8a and stores it in the system memory 3.

  The FD device 9 reads a program from the FD 9 a and stores it in the system memory 3. Details will be sequentially described below.

  In FIG. 1, the communication device 7, the CD-ROM device 8, the FD device 9, etc. may be external devices connected to a device such as a personal computer, and the CPU 1 and the coordinate detection microcomputer 4 are simply connected. Needless to say, a single CPU may be used. Similarly, the system memory 3 and the flash ROM 5 may be composed of a single memory.

  FIG. 2 is a flowchart for explaining the overall operation of the present invention.

  In FIG. 2, step S1 performs system boot-up.

  In step S2, an input / output control program (BIOS) is loaded. In order to enable the CPU 1 of FIG. 1 to operate, the BIOS is read from a nonvolatile memory such as a flash memory in the various circuits 2, loaded into the system memory 3, and started.

  In step S3, a user ID is input. This is to input a user ID by inputting a coordinate value on a coordinate detector 6 which will be described later using FIGS. 3 to 22 according to the present invention.

  In step S4, ID authentication is performed. This authenticates whether the ID of the user ID input in step S3 matches that registered.

  In step S5, it is determined whether it is OK. This is determined as a result of the authentication in step S4. If the determination result of step S5 is YES, the process proceeds to step S6. If the determination result in step S5 is NO, it is determined in step S12 that they do not match, the process ends, and it is prohibited to proceed to the next step S6.

  In step S6, since the ID of the user ID is authenticated in step S5, the operating system (OS) is loaded.

  In step S7, the application is activated. Note that ID authentication similar to that performed during OS loading can be performed when the application is activated.

  In step S8, a user ID is input.

  In step S9, ID authentication is performed.

  In step S10, it is determined whether the result of the authentication in step S9 is OK. If the determination result of step S10 is YES, the application is actually activated in step S11. If the determination result of step S10 is NO, it is determined that there is a mismatch in step S13, the process ends, and it is prohibited to proceed to step S11. Here, Steps S8 to S10 and S13 correspond to Steps S3 to S5 and S12 described above, and thus detailed description thereof is omitted.

  As described above, when the computer system constituting FIG. 1 is started, after loading the BIOS and before loading the OS, the user ID input and ID authentication according to the present invention are performed, and the application according to the present invention is also started. User ID input and ID authentication are performed. In this case, the user ID input and ID authentication are compared with the conventional user ID using text data consisting of numbers, alphabets, and the like. Alternatively, security is enhanced by determining that the user ID is authenticated when the coordinate value pattern is correct. Hereinafter, user ID input and ID authentication will be described in detail.

  FIG. 3 shows a card position change flowchart of the present invention. Here, the software on the CPU is software (program) when the CPU 1 in FIG. 1 reads a program from the system memory 3 and performs processing, and the coordinate detection microcomputer is a coordinate operating with the program read from the flash ROM 5 in FIG. This is a detection microcomputer 4. The software on the CPU and the coordinate detection microcomputer perform the processes described in the lower part.

  In FIG. 3, step S21 generates a random number as the location number. For example, locations No. 1, 2, 3, and 4 are assigned to, for example, four corners on the screen 11 of FIG. 4 to be described later, random numbers are generated within 1 to 4, and one of the locations is selected by the random number.

  In step S22, the coordinate detection microcomputer 4 is notified of the location No, and the coordinate detection microcomputer is notified of the activation of the ID authentication process. Thereby, the location No. selected by the random number in step S21 is notified, and the ID authentication processing of the coordinate detection microcomputer 4 is started.

  A step S23 displays a card frame corresponding to the location No. This is because the card frame is displayed at the location selected by the random number in step S21, for example, the location No. 1 in FIG. 4, and the coordinates of the card via the hole or hole of the card, the notch or the mark are matched with the card frame to the user. Prompt for input.

  In step S31, the ID processing of the coordinate detection microcomputer is activated in step S22.

  In step S32, the registration data corresponding to the designated location No is used as comparison data. As registration data corresponding to the location No. notified in step S22, registration data corresponding to the location No. is extracted from registration data in FIG.

  In step S33, a coordinate check is performed. In step S23, a card frame is displayed on the touch panel or tablet screen 11 as shown in FIG. 4, and the user places the card on the card frame and inserts the hole, hole, notch or mark portion with a pen or the like. The coordinate value pressed on the screen is detected by pressing and a check is made by comparing whether the detected coordinate value matches the registered data extracted in step S32.

  A step S34 notifies the authentication result to the software on the CPU 1.

  In step S24, it is determined whether authentication has been completed. Step S24 is repeated until the authentication result of step S34 is obtained. When the authentication result is obtained from step S34, since the authentication is completed, the process proceeds to step S25.

  In step S25, processing corresponding to the authentication result is performed. For example, when the authentication result is OK, the OS or application shown in FIG. 2 is loaded / started. When the authentication result is NG, the OS or application shown in FIG. As described above, a place is selected by a random number, for example, the place No. 1 in FIG. Is pressed with a pen or the like, the coordinate value is read, and the registered data corresponding to the location No. are collated to match, it is possible to determine authentication OK, and when they do not match, authentication NG can be determined.

  Further, according to the present invention, coordinates can be easily input simply by performing the above-described coordinate input with a pen, and authentication is performed using the coordinates. Therefore, FIG. 29 and FIG. It is possible to provide an authentication method that matches the operability of the portable pen input device. In particular, portable pen input devices such as a pen input device and a touch panel as shown in FIG. 29 and FIG. 30, which will be described later, may not have a keyboard. . Under such usage conditions of the device, it is possible to perform authentication that matches the usage pattern of the pen input device or the pen computer, and authentication without impairing operability is possible.

  FIG. 4 shows an example of a user ID input screen image of the present invention. In this user ID input screen image example, as shown in the figure, the card frame 12 shown in the figure is selected and displayed by a random number in response to the message “Put the card and enter with a pen”. The card is put on the card frame 12, and the hole or hole, notch or mark portion of the card is pressed with a pen. The apparatus reads the coordinate value pressed on the screen 11 and compares it with the registered data, and it is possible to determine authentication OK when they match and authentication NG when they do not match.

  FIG. 5 is an explanatory diagram in a case where the position to which the card of the present invention is applied can be changed. FIG. 5A shows a screen image example of the touch panel. This touch panel includes a display having a transparent digitizer or tablet (resistive film) on a display such as a CRT, a liquid crystal display, or a plasma discharge panel, and a display having an electromagnetic induction type digitizer under the display. In the case of the electromagnetic induction method, coordinates are detected by sensing magnetism from a pen (or stylus) by a coordinate detector disposed below a screen (for example, a liquid crystal display). At the four corners on the screen 11, place No. 1, place No. 2, place No. 3, and place No. 4 of the card frame 12 are determined as shown in the figure, and two points (point No. 1 and point No. 2) are respectively set as reference coordinates as shown in the figure. When specified and registered as a value, the result is as shown in FIG.

  FIG. 5B shows an example of registered data. In this registered data example, location No. 1, location No. 2, location No. 3 and location o4 are determined as shown in the four corners on the screen 11 in FIG. 5A, and the coordinates of points 1 and 2 are designated at each location. And registered as shown in the figure. For example, the point No1 of the location No1 is determined and registered as coordinates (x11, y11) and No2 is determined as coordinates (x12, y12). In addition, what is necessary is just to determine arbitrarily the number of the points to register in each place.

  As described above, the card frame 12 on the screen 11 is determined by a random number, and the positions to be displayed are determined as the four corner places No1, No2, No3, and No4, and the coordinates of the points No1 and No2 at each place. Specify each to register. As a result, the card is determined by random numbers in any of the four shown, and the hole or hole, notch or mark opened at the position of point No1, point No2 with a pen is pressed against the displayed card frame and coordinates If the card is compared with the registered data and the authentication is determined to be OK, the card frame can be found by scratching the screen 11 when the card is placed in the same place, It is possible to eliminate the situation where a third party remembers the place. FIG. 6 is an explanatory diagram of the structure of registration data according to the present invention.

  FIG. 6A shows an example of the lower left origin of the screen. This shows an example in which the illustrated position of the lower left place is the origin (0, 0) when the card frame 12 is displayed at the four places in the four corners of FIG. Here, the coordinates of points 1 to 4 shown in the figure are designated and registered.

  FIG. 6B shows an example of registered data. This displays the card frame 12 as shown in FIG. 6A, and points 1 (x1, y1), 2 (x2, y2), 3 (x3, y3), 4 (x4, y4). ) Is registered.

  As described above, the coordinates of the four points 1, 2, 3, and 4 are registered as registration data in the card frame 12, and the hole or hole of the card frame displayed on the screen 11 of the touch panel, the notch Alternatively, when the mark is pressed at four locations with a pen and the coordinates of the pressed point coincide with the coordinate values of point 1, point 2, point 3, and point 4 of the registered data, the authentication is OK, and the authentication NG when no match is found. Can be determined.

  FIG. 7 shows a flowchart for explaining the operation when the input order of the present invention is not limited.

  In FIG. 7, step S41 determines whether or not the coordinate input is the first time. If the determination result of step S41 is YES, the coordinate value is saved in step S42. If the determination result of step S41 is NO, step S41 is repeated and the process waits. No time-out is provided for the first input, and the user's input start is kept waiting.

  In step S43, it is determined whether coordinate input is present. If the decision result in the step S43 is YES, the coordinates are saved in a step S44, and the process returns to the step S43 to repeat. On the other hand, when the determination result of step S43 is NO, the process proceeds to step S45.

  In step S45, it is determined whether an input waiting timeout (a certain time has elapsed). If the determination result in step S45 is YES, it is determined that the coordinate input has been completed after a lapse of a certain time, and the process proceeds to step S47. On the other hand, if the determination result in step S45 is NO, it has been determined that the fixed time has not elapsed and the coordinate input has not ended, so the process returns to step S43 and repeats.

  In step S46, since the determination result in step S45 is YES and it is determined that the coordinate input is completed, the comparison is made with the registered data. This compares the input coordinate value with the registered data.

  In step S47, it is determined whether or not they match. If the determination result in step S47 is YES, ID authentication output is performed in step S48. If the determination result in step S47 is NO, ID mismatch is output. The ID authentication output and the ID mismatch output are notified to the CPU 1. For example, in the case of an ID mismatch output, the CPU 1 may perform control so as to display the ID mismatch in response to this, and the same is true in the following description. Control may be performed.

  As described above, after the first coordinate is input with the pen by placing the card on the card frame 12 on the screen 11, the coordinate input is sequentially performed, and the coordinate input is not performed even if a certain time has elapsed. The card is displayed on the card frame 12 on the screen 11 by comparing the input coordinate value with the registered data and outputting the ID authentication when they match, and outputting the ID mismatch when they do not match. It is possible to perform ID authentication with high security by pressing a hole or hole, notch or mark with a pen and inputting a coordinate value.

  FIG. 8 is a flowchart for explaining the operation when the input order of the present invention is asked.

  In FIG. 8, step S51 determines whether or not the coordinate input is the first time. If the determination result of step S51 is YES, the coordinate value is saved in step S52. If the determination result in step S51 is NO, step S41 is repeated and the process waits.

  Step S53 compares with the first registration data. This compares the first input coordinate value saved in step S52 with the first registration value of the registration data.

  In step S54, it is determined whether or not they match. If the decision result in the step S54 is YES, it is found that there is a match, and the process advances to a step S56. If the determination result in step S54 is NO, it is determined that there is a mismatch, so that a mismatch is output and the process ends.

  In step S55, it is determined whether coordinate input is present. If the determination result of step S55 is YES, the coordinates are saved in step S56, and the process proceeds to step S57. If the determination result of step S55 is NO, the process proceeds to step S61. A step S57 compares the number of inputs with the number of registrations.

  In step S58, it is determined whether the number of inputs exceeds the number of registrations. If the determination result in step S58 is YES, it is found that the number of inputs has exceeded the number of registrations, so a mismatch is output and the process ends. If the determination result of step S58 is NO, the process proceeds to step S59.

  In step S59, the input data based on the coordinate input is compared with the registered data.

  In step S60, it is determined whether the input data compared in step S59 matches the registered data. If the decision result in the step S60 is YES, it is found that they match, so the process returns to the step S55 and waits for the input of the next coordinate. If the determination result in step S60 is NO, it is determined that there is a mismatch, so a mismatch output is output and the process ends.

  In step S61, it is determined that there is no coordinate input in NO in step S55, and therefore it is determined whether an input waiting time-out (a certain time has elapsed). If the determination result in step S61 is YES, it is determined that the coordinate input has been completed after a certain period of time, and the process proceeds to step S62. On the other hand, if the determination result in step S61 is NO, it has been determined that the fixed time has not elapsed and the coordinate input has not ended, so the process returns to step S55 and waits for the input of the next coordinate.

  In step S62, the input number and the registered number are compared.

  In step S63, it is determined whether the input number compared in step S62 matches the registered number. If the determination result in step S63 is YES, ID authentication output is performed. If the determination result of step S63 is NO, a mismatch output is made.

  As described above, when coordinates are input in the order specified by the pen by placing the card on the card frame 12 on the screen 11 of the touch panel, the input coordinates and the registered data are compared in order, and a predetermined time has passed. If there is no coordinate input, it is determined that the coordinate input has been completed, and the coordinates input so far are compared with the registered data, and ID authentication is output when the numbers match and the numbers are equal. By applying the card to the card frame 12 on the screen 11 and pressing the holes or holes, notches or marks in a predetermined order with a pen, and sequentially inputting the coordinate values, the ID with high security and a large number of IDs is obtained. Authentication can be performed.

  FIG. 9 shows a card position change flowchart of the present invention.

  In FIG. 9, step S71 determines the card position (x0, y0) with a random number.

  In step S72, the card position coordinates (x0, y0) are notified to the coordinate detection microcomputer, and the activation of the ID authentication process is notified to the coordinate detection microcomputer.

  A step S73 displays a card frame corresponding to the card position. Instead of the card frame, an arbitrary position marker that can indicate the position where the card should be placed may be displayed.

  In step S81, the ID authentication process of the coordinate detection microcomputer 4 is activated in response to the notification in step S72.

  A step S82 calculates comparison coordinates from the registration data and card position coordinates. This calculates a comparison coordinate value for the registered data based on the card position coordinates (x0, y0) notified in step S72.

  In step S83, a coordinate check is performed. In step S73, the card frame 12 is displayed on the screen as shown in FIG. 10 (a), and the user applies the card to the card frame 12 and the hole, hole, notch or mark portion. Is pressed with a pen or the like to detect the pressed coordinate value on the screen 11, and the detected coordinate value is compared with the comparison coordinate value calculated in step S82 to check.

  A step S84 notifies the authentication result to the software on the CPU1.

  A step S74 decides whether or not it has been authenticated. Step S74 is repeated until the authentication result of step S84 is obtained. When the authentication result is obtained from step S84, since the authentication is completed, the process proceeds to step S75.

  In step S75, processing corresponding to the authentication result is performed. For example, when the authentication result is OK, the OS or application shown in FIG. 2 is loaded / started. When the authentication result is NG, the OS or application shown in FIG. Thus, the card position (x0, y0) is determined by random numbers, for example, the card position (x0, y0) in FIG. 10 is determined, the card frame 12 is displayed at the card position (x0, y0), and the card frame 12 is displayed. The user places a card and presses the hole or hole, notch or mark of the card with a pen, etc., reads the coordinate value, and compares the registered data with the comparison coordinate value calculated from the card position (x0, y0). It is possible to determine that authentication is OK when they match, and authentication NG when they do not match.

  FIG. 10 shows a data structure explanatory diagram when the software on the CPU of the present invention notifies the position of the card.

  FIG. 10A shows an example of the card position on the touch panel screen. This card position (x0, y0) is arbitrarily determined by random numbers. The card frame 12 is displayed as shown in the drawing with this card position (x0, y0) as the origin. Then, a card is applied to the card frame 12, and coordinates are input with a pen from the hole, hole, notch or mark.

  FIG. 10B shows an example of the in-card coordinates. The lower left of the card is the origin (0, 0), and the coordinates of the four points are set as shown in the figure. The card frame 12 in FIG. 10A is arranged so that the origin (0, 0) of this card coincides with the origin (x0, y0) determined by a random number on the screen 11, and coordinates of four points. Is calculated by adding the coordinates of the origin (x0, y0) (step S82 in FIG. 9).

  FIG. 10C shows an example of registration data. Here, the point numbers correspond to the four point numbers specified in the card in FIG. The card origin (x0, y0) is an origin determined by a random number for displaying the card frame 12 on the screen 11 in FIG. The card inner hole coordinate values are the four card inner hole coordinate values shown in FIG. The comparison coordinate values are respectively calculated by adding the origin (x0, y0) determined by random numbers on the screen 11 in FIG. 10A to the four in-card coordinate values in FIG. 10B. is there.

  As described above, the card position (x0, y0) in FIG. 10A is determined by random numbers and the card frame 12 is displayed, and the card position (x0, y0) is added to the in-card coordinates on the screen 11. It is possible to obtain the coordinate value of the hole and to set the comparison coordinate value, and when the actually detected coordinate value matches the comparison coordinate value, the authentication is OK, and when they do not match, the authentication NG is possible.

  FIG. 11 shows a flowchart using the software KB of the present invention.

  In FIG. 11, step S91 sets 10 × n soft 10 keys corresponding to the card size on the screen. This is a random number on the screen 11 in FIG. 12A, in which n rows of 10 keys 0, 1, 2, 3,... 9 in FIG. Set to the determined origin (x0, y0) position.

  A step S92 calculates comparison coordinates from the software 10 key position coordinates and the registered data. As described above, the origin (x0, y0) is added to the software 10 key position, and the coordinates on the screen 11 are calculated as comparison coordinates.

  In step S93, the soft 10 key itself is not displayed on the screen, and only the frame of the card is displayed.

  In step S101, if there is an input on the screen, the input coordinates are notified to the software on the CPU.

  In step S102, it is determined whether there is an input. If the decision result in the step S102 is YES, the coordinates are detected in a step S103 and notified to the software on the CPU in a step S104.

  In step S94, coordinate check and 10-key analysis are performed. This is based on the notification of the input coordinates in step S104, which 10 key coordinates the input coordinates correspond to is converted to 10 keys.

  Step S95 performs password type security. This is so-called password-type security, in which the column of numerical values (0, 1, 2,... 9) converted to 10 keys in step S94 is compared with the registered data to determine whether they match.

  In step S96, processing corresponding to the authentication result is performed.

  As described above, the frame of the soft 10 key is set based on the origin (x0, y0) determined by the random number on the screen 11, only the frame of the 10 key is displayed, the 10 key itself is not displayed, Enter the coordinates by pressing the hole or hole, notch or mark with a pen by applying the card described above, and converting which of the 10 keys was pressed based on the read coordinate value, It is possible to authenticate by sequentially inputting an arbitrary numeric string or the like on the screen by determining that authentication is OK when they are compared and authentication is NG when they do not match.

  FIG. 12 is an explanatory diagram of a data structure when a key code is notified by placing a card on the non-displayed soft 10 key of the present invention.

  FIG. 12A shows a coordinate detection example of the coordinate detection microcomputer. This screen 11 shows an image in which only the frame of the soft 10 key is displayed based on the origin (x0, y0) determined by random numbers. As shown in the figure, the coordinate values of one point in one line and four points in a total of four lines are determined as shown in the frame of the soft 10 key.

  FIG. 12B shows an example of coordinate values of the software 10 key by software on the CPU. Here, ten soft 10 keys are set to 0, 1, 2,... 9 per line, and coordinate values are set for four lines as shown in the figure. The lower left corner is the origin (0, 0).

  (C) of FIG. 12 shows an example of input coordinate values notified to the software on the CPU by the coordinate detection microcomputer. Here, for the points 1, 2, 3, and 4, the coordinate values of the points 1, 2, 3, and 4 in the frame of the card in FIG.

  FIG. 12D shows an explanatory diagram of comparison by software on the CPU. The point No. and the received coordinates are the values of the input coordinates received from the coordinate detection microcomputer in FIG. The origin coordinates of the soft 10 key are origins (x0, y0) determined by random numbers. The soft 10-key comparison coordinates are obtained by subtracting the origin coordinates from the received coordinates for x and y, respectively, and converting them into coordinates within the soft 10 keys. The comparison results are obtained by comparing the coordinate values of the software 10 key comparison coordinates within the software 10 key shown in FIG. The result is obtained by converting the coordinate values of the comparison results into corresponding numbers from 0, 1, 2,. In the figure, since the result is “2692”, the key code is sent out.

  As described above, only the frame of the soft 10 key is displayed on the screen 11 based on the origin (x0, y0) determined by random numbers, and the hole, hole, notch or mark of the card applied to the frame is pressed with the pen. Sometimes the input coordinates are taken in, converted to which soft 10 key is pressed, a result is obtained, and a key code corresponding to this result is sent out. As a result, it is possible to determine authentication OK when a plurality of numbers corresponding to the sent key code and the registered data match, and authentication NG when they do not match.

  FIG. 13 shows an explanatory diagram (other example) of a data structure when a key code is notified by placing a card on the non-displayed soft 10 key of the present invention.

  FIG. 13A is the same as the data of FIG. 12D described above. In FIG. 12, the software on the CPU controls the soft 10 key, but in FIG. 13, the coordinate detection microcomputer controls the soft 10 key. Therefore, the software on the CPU displays the card frame 12 on the screen 11 and notifies the coordinate detection microcomputer 4 of the origin (x0, y0) determined by the random number of the software 10 key. Upon receiving the notification, the coordinate detection microcomputer 4 converts the key code of the result obtained as described above (for example, “2692” in the figure) into a normal keyboard interface, and the hardware block diagram of FIG. To the external KB interface of the KB microcomputer 13 shown in FIG. The KB microcomputer 13 thereafter notifies the key code to the software input unit on the CPU 1 via the OS.

  FIG. 13B shows a hardware block diagram. As described above, this is a hardware block diagram in the case where the coordinate detection microcomputer 4 controls the software 10 key which has been performed by the software on the CPU 1 described in FIG. The data is sent to the software input unit on the CPU 1 via the KB microcomputer 13. The tablet 15 is an example of the coordinate detector 6 of FIG.

  FIG. 14 shows a flowchart using the software KB of the present invention.

  In FIG. 14, step S111 determines the card position (x0, y0) with a random number.

  A step S112 notifies the coordinate microcomputer and starts the ID authentication process.

  Step S113 displays a card frame corresponding to the card position.

  Step S121 starts ID authentication processing.

  In step S122, 10 × n soft 10 keys corresponding to the card position (x0, y0) are set on the screen.

  In step S123, coordinate detection and 10-key analysis are performed. As described above, when the card is placed on the card frame and the hole, hole, notch or mark of the card is pressed with the pen, the input coordinates are detected and the position on the corresponding soft 10 key is obtained. To the corresponding numerical value (result).

  A step S124 sends a key code. In this process, the numerical value (result) obtained in step S123 is converted into a key code and transmitted.

  Step S114 performs password type security. As described above, this is a so-called password type in which a sequence of numerical values (0, 1, 2,... 9) converted to 10 keys in step S123 is compared with registered data to determine whether they match. Do security.

  In step S115, processing corresponding to the authentication result is performed.

  As described above, the frame of the soft 10 key is set based on the origin (x0, y0) determined by the random number on the screen 11, only the frame of the 10 key is displayed, the 10 key itself is not displayed, Enter the coordinates by pressing the hole or hole, notch or mark with a pen by applying the card described above, and converting which of the 10 keys was pressed based on the read coordinate value, When the comparison results in a determination that the authentication is OK and the case where they do not match, it is determined that the authentication is NG, and it is possible to input an arbitrary numeric string from the screen for authentication.

  In the specific example, 10 × n is described, but the software 10 key can be arranged as m × n. Needless to say, a soft keyboard composed of keys on an ordinary keyboard such as alphabets, kana, and symbols may be used instead of the soft 10 keys.

  FIG. 15 shows a structural example of the card of the present invention.

  FIG. 15A shows an example of a card in which holes are formed at arbitrary positions on an m × n grid. In the figure, four holes are made and shipped with the computer system. At this time, the coordinate values of the positions of the four holes shown in the figure are registered as registration data in the internal table.

  FIG. 15B shows an example of a card that allows the user to easily punch out any part of the intersection of the m × n grid.

  (B-1) of FIG. 15 shows the state of the card which can be easily punched at the intersection of the m × n grid.

  (B-2) of FIG. 15 shows an enlarged view of an intersection portion of the grid of (b-1) of FIG. As shown in the enlarged view, the intersection of the grid leaves a part of the circle and punches out the other, and the user presses the intersection of the desired grid with a pen or the like to punch out, making a hole at any location It is made to be able to.

  (B-3) of FIG. 15 shows an example in which “1690” is set by punching out the illustrated portion of the grid of 10 columns × n rows. The user can register an ID of a uniquely created card in the apparatus.

  As described above, by making a card in an n × m grid and making a hole at an arbitrary coordinate position, the card is placed on the card frame 12 displayed on the screen 11 with a pen as described above. It is possible to input a predetermined coordinate value by pressing the button.

  Next, in the present invention, shapes of cards other than the cards described so far will be described with reference to FIG. In the resistive film system, a case where a card has a plurality of protrusions as shown in FIG. 16 will be described. By placing a transparent resistive film on the screen 11 and pressing the card 34 with a pin as shown in the figure on the displayed card frame, the resistive film is pressed with three pins in the figure, and the lower expression in the figure is As shown, a resistance value corresponding to three weighted average coordinates is detected. For this reason, it is set in advance so that a desired weighted average coordinate is obtained depending on the positions of a plurality of pins of the card 34, and it is determined that the authentication is OK when compared with the registered data, and the authentication NG is determined when they do not match. It becomes possible. FIG. 17 shows a comparative explanatory diagram (fixed value) of the present invention. The coordinates detected by the position detection device include a detection error, and there is a habit of how to apply the user's pen, and it is always necessary to provide an allowable range for comparison between the detected coordinates and the registered coordinates.

  In FIG. 17, step S121 sets allowable ranges Δx and Δy. This sets the allowable range at the time of detection by placing the card on the card frame 12 displayed on the screen 11 described above, pressing it with a pen, inputting coordinates, and fixed values Δx and Δy.

  In step S122, X is compared with xn ± Δx. This compares X in the input coordinates (X, Y) with a value obtained by adding ± Δx to xn in the n-th registered data (xn, yn).

  In step S123, it is determined whether it is within the range of xn−Δx ≦ X ≦ xn + Δx. This is to determine whether the input coordinate X is within the range of the allowable error Δx set in step S121. If the decision result in the step S123 is YES, it is found that it is within the allowable range, so the process advances to a step S124. If the determination result in step S123 is NO, it is determined that the result is out of the allowable range, so that a mismatch is output and the process ends.

  In step S124, Y and yn ± Δy are compared as in step S122. This compares Y in the input coordinates (X, Y) with a value obtained by adding ± Δy to yn in the n-th registered data (xn, yn).

  In step S125, it is determined whether it is within the range of yn−Δy ≦ Y ≦ yn + Δy. This is to determine whether the input coordinate Y is within the allowable error Δy set in step S121. If the determination result in step S125 is YES, since it is found that it is within the allowable range, coordinate coincidence is output in step S126, and the process ends. If the determination result in step S125 is NO, it is determined that the result is out of the allowable range, so a mismatch output is made and the process ends.

  As described above, the allowable ranges Δx and Δy (fixed values) are set, and when the coordinate input (X, Y) detected from the screen 11 is within the allowable range Δx and Δy of the registered data, it is determined that the coordinates match, and the coordinate input Even if there is a certain amount of time error, it is judged correctly if it is within the allowable range.

  FIG. 18 shows a security level setting explanatory diagram of the present invention.

  FIG. 18A shows a flowchart.

  In FIG. 18A, step S131 checks the security level.

  In step S132, allowable ranges Δxm and Δym matching the security level are set. For example, the allowable ranges Δxm and Δym are set small to increase the security level, and the allowable ranges Δxm and Δym are set large to decrease the security level.

  Step S133 performs comparison. The comparison is performed according to the above-described flowchart of FIG. 17 based on the allowable ranges Δxm and Δym set in accordance with the security level in step S132, and a coordinate match output or a coordinate mismatch output is performed.

  As described above, by setting the allowable ranges Δx and Δy to be small / large depending on whether the security level is high or low, it is possible to set the input coordinate value comparison judgment strictly or gently.

  In FIG. 18B, the security level 1 shows the case where the judgment is made most gradual, and the security level 1 (el) is made the most severe.

  FIG. 19 shows an explanatory diagram of the relative coordinate range setting of the present invention. The card position applied by the user with respect to the displayed card frame always includes a positioning error. This can be absorbed by setting an allowable range for the card origin coordinates (x0, y0).

  FIG. 19A shows an example of data. Here, the point Nos. Are Nos. 1, 2, 3, and 4 set in the card. The card origin is the origin (x0, y0) for displaying the card frame on the screen 11 and its allowable range (Δx0, Δy0). The registration data of the hole coordinates in the card is registration data of the hole coordinates in the card. As shown in the figure, the min (minimum value) of the comparison coordinate range is a value obtained by subtracting the allowable range (Δx0, Δy0) from the card origin (x0, y0) and adding the coordinates of each point to the subtracted value. The comparison coordinate range max (maximum value) is a value obtained by adding the allowable range (Δx0, Δy0) to the card origin (x0, y0) and adding the coordinates of each point to the added value as shown in the figure.

  FIG. 19B shows a flowchart.

  In FIG. 19B, step S141 calculates the comparison coordinates min / max from the registration data, the card origin, and the allowable range. As described with reference to FIG. 19A, the comparison coordinates min / max are calculated from the registration data (the registration data of the hole in the card), the card origin, and the allowable range.

  A step S142 performs a coordinate check. Put a card on the card frame displayed on the screen 11 and press a hole or hole, notch or mark with a pen to input coordinates, determine whether the coordinate input is in the range of min and max of comparison coordinates, Authentication OK when it is within the range, and authentication NG when it is out of the range.

  In step S143, the authentication result is notified to the software on the CPU.

  As described above, the comparison coordinate range (min / max) is calculated based on the registration data in the card, the origin of the card, and the allowable range, and the card is displayed on the screen 11 so that the hole or hole is cut. It is determined whether or not the coordinate input when the notch or mark is pressed with the pen and the coordinate is input is within the range of the comparison coordinates min and max, and authentication OK is determined when it is within the range, and authentication NG is determined when it is out of the range. It becomes possible.

  FIG. 20 shows a learning explanatory diagram of the allowable range of the present invention.

  In FIG. 20, step S151 inputs n times. This repeats n times that the card is put on the card frame displayed on the screen 11 and the coordinates are input by pressing the hole, hole, notch or mark with a pen.

  Step S152 performs statistical analysis.

  In step S153, an allowable range (Δx, Δy) is calculated. In these steps S152 and S153, statistical analysis is performed based on the values input n times in step S151, for example, an average value is obtained, and a certain range around the obtained average value is calculated from the registered data as an allowable range. .

  As described above, when a coordinate is input by placing a card on the card frame 12 displayed on the screen 11 and pressing a hole or hole, a notch or a mark with a pen, the average value of the coordinate input is obtained and the corresponding data is obtained from the registered data. By calculating a certain range of the average value as an allowable range, even if the point of coordinate input is shifted due to the habit of each user, it becomes possible to obtain an allowable range in advance and set it narrowly for each user, thereby increasing the security level. it can.

  FIG. 21 is a flowchart for explaining the operation of the end of detection according to the present invention (when there is no order). The user himself / herself can input by a series of operations without stagnation when inputting his / her ID. Therefore, by calculating the end detection from the average of the user's own input instead of a fixed time-out, it is possible to detect the end when a long no-input time appears for the input speed so far during input. Confirmation security can be increased.

  In FIG. 21, in step S161, an initial value t0 is set as an input waiting timeout t.

  In step S162, it is determined whether the coordinate input is the first time. If the determination result of step S162 is YES, the coordinates are saved in step S163, and the process proceeds to step S164. If the determination result of step S162 is NO, the process returns to step S162 and waits.

  In step S164, it is determined whether the input is coordinates. If the decision result in the step S164 is YES, the coordinates are saved in a step S165, the average input interval tAVE is calculated from the time interval from the previous input in a step S166, and the input waiting time-out t is updated. As a result, the input waiting time-out t is updated to the average input interval tAVE. And it returns to step S164 and repeats. On the other hand, when the determination result of step S164 is NO, the process proceeds to step S167.

  In step S167, it is determined whether the input waiting timeout t × n has been exceeded. If the determination result in step S167 is YES, it is determined that the current waiting time has exceeded the input waiting time-out t × n times, so that it is determined that the coordinate input has been completed, and is compared with the registered data in step S168. . On the other hand, if the determination result of step S167 is NO, the process returns to step S164 and waits for coordinate input.

  In step S169, it is determined whether or not they match. If the determination result in step S169 is YES, ID authentication output is performed. If the determination result of step S169 is NO, a mismatch output is made.

  As described above, the average value of the coordinate input intervals is obtained, and it is determined that the coordinate input is completed when there is no coordinate input for a time interval of n times the obtained average value. It is possible to determine that the authentication is OK when the data match and the authentication is NG, and the authentication NG when the data does not match.

  FIG. 22 is a flowchart for explaining the operation of the end of detection according to the present invention (when there is an order).

  In FIG. 22, step S171 sets an initial value t0 as an input waiting time-out t.

  In step S172, it is determined whether the coordinate input is the first time. If the determination result of step S172 is YES, the process proceeds to step S173. If the determination result of step S172 is NO, the process returns to step S172 and waits.

  In step S173, the coordinates are saved.

  In step S174, the input data by the first coordinate input is compared with the registered data. This compares the coordinate input saved in step S173 with the registered data.

  In step S175, it is determined whether or not they match. If the determination result of step S175 is YES, the process proceeds to step S176. If the determination result in step S175 is NO, a mismatch is output and the process ends.

  In step S176, it is determined whether the input is coordinates. If the determination result of step S176 is YES, the process proceeds to step S177. If the determination result of step S176 is NO, the process proceeds to step S183.

  In step S177, since it is determined that there is a coordinate input in step S176, the coordinate input is saved.

  In step S178, the input number is compared with the registered number.

  In step S179, it is determined whether the number of inputs exceeds the registered number. If the determination result in step S179 is YES, a mismatch is output and the process ends. If the determination result of step S179 is NO, the process proceeds to step S180.

  In step S180, the average input interval tAVE is calculated from the time interval from the previous input, and the input waiting time-out t is updated. As a result, the input waiting time-out t is updated to the average input interval tAVE.

  In step S181, the coordinate input is compared with the registered data.

  In step S182, it is determined whether the coordinate input compared in step S181 matches the registered data. If the determination result of step S182 is YES, the process returns to step S176 and waits. If the determination result in step S182 is NO, a mismatch is output and the process ends.

  In step S183, it is determined whether the input waiting timeout t × n has been exceeded. If the determination result in step S183 is YES, it is determined that the current waiting time has exceeded the input waiting timeout t × n times, so it is determined that the coordinate input has ended, and the process proceeds to step S184. If the determination result of step S183 is NO, the process returns to step S176 and waits for coordinate input.

  In step S184, the input count is compared with the registration count.

  In step S185, it is determined whether or not they match. If the determination result in step S185 is YES, it has been found that the number of times of input and the number of times of registration coincide with each other, so that ID authentication is output, and the process ends. If the determination result of step S185 is NO, a mismatch is output and the process ends.

  As described above, the average value of the coordinate input intervals is obtained, and it is determined that the coordinate input is completed when there is no coordinate input for a time interval of n times the obtained average value. It is possible to determine that the authentication is OK when the number of times matches with the registered data, and that the authentication is NG when they do not match.

  Next, according to the order shown in the flowchart of FIG. 23, the frame of the card 34 on the coordinate detector is not displayed with reference to FIG. 24, and the card 34 is placed on the coordinate detector such as a tablet, for example, Operations in the case of pressing a notch or mark with a pen will be sequentially described in detail.

  FIG. 23 shows a flowchart for applying the card 34 to an arbitrary position on the tablet or touch panel of the present invention.

  23, in step S191, the software on the CPU 1 activates the ID authentication process for the coordinate detection mine 4.

  In step S192, the coordinate detection microcomputer 4 starts ID authentication.

  In step S193, the card position is detected from the card origin (x00, y00) and other specific points (x01, y01) on the card. For example, as shown on the tablet 21 in FIG. 24A described later, the pen is pressed first, the lower left coordinates (x00, y00) of the card 34, and the second pressed with the pen. The lower right coordinates (x01, y01) of the card 34 are detected as the card origin (x00, y00) and other specific points (x01, y01), respectively.

  In step S194, a 10 × n soft 10 key corresponding to the detected card position is set on the screen. Here, the soft 10 key is virtually set on the screen, and the card frame is not displayed.

  In step S195, coordinate detection and 10-key analysis are performed. In this case, when a hole or hole, notch or mark of the card 34 is pressed with a pen, the input coordinates are detected, the corresponding position on the software 10 key is obtained and converted into a corresponding numerical value (result).

  In step S196, a key code is transmitted. In this process, the numerical value (result) obtained in step S195 is converted into a key code and transmitted.

  Step S197 performs password type security. As described above, this is a so-called password type in which a column of numerical values (0, 1, 2,... 9) converted to 10 keys in step S195 is compared with registered data to determine whether they match. Do security.

  Step S198 performs processing corresponding to the authentication result.

  As described above, the origin (x00, y00) and other specific points (x01, y01) are input on a coordinate input device such as a tablet or a touch panel to virtually set the soft 10 keys, and the 10 key frame and 10 keys Both of them are hidden, the card 34 is applied, a hole or hole, a notch or a mark is pressed with a pen, and coordinates are input. Based on the read coordinate value, which of the 10 keys is pressed is converted. Later, it is possible to authenticate by inputting an arbitrary number string etc. from a tablet that cannot display a card frame etc. by determining that authentication is OK when compared with registered data, and authentication NG when it does not match It becomes.

  Needless to say, the authentication method using the soft 10 key in the flowchart shown in FIG. 23 may be replaced with the other methods described above.

  FIG. 24 is an explanatory diagram of a data structure when the card position of the present invention is an arbitrary position on the tablet or touch panel.

  FIG. 24A shows an image of coordinate input on a tablet or touch panel. The card 34 is placed on the tablet 21, and the card origin (x00, y00) and other specific points (x01, y01) are sequentially pressed with a pen in the lower left corner and the lower right corner of the card. Enter. The position of the card 34 is determined from the coordinate values and inclinations of these two card origins (x00, y00) and other specific points (x01, y01). Next, coordinate input (x0, y0), (x1, y1), (x2, y2), (x3, y3) by sequentially pressing four holes or holes, notches or marks on the card 34 with a pen. I do.

  FIG. 24B shows an example of registered data.

  In (b) of FIG. 24, the point No is a number given to the sequential in which coordinates are input by pressing a hole or hole, notch or mark on the card 34 in (a) of FIG. 4 from 1 to 4.

  The detected coordinates are the detected coordinates (x1, y1), (x2, y2), (x3, y3), (x4, y4) detected at points No1 to No4.

  The card position detection coordinates are based on the coordinate values of the card origin (x00, y00) and other specific points (x01, y01) at the lower left corner of the card 34 input in FIG. , Cos Δθ and distance l 0 are obtained as shown in the figure. The software 10 key comparison coordinates are based on the card position detection coordinates for the coordinates (x1, y1), (x2, y2), (x3, y3), (x4, y4) of the points No. 1 to No. 4. The coordinate values (x1 ′, y1 ′), (x2 ′, y2 ′), (x3 ′, y3 ′), (x4 ′, y4 ′) on the 10th key are converted by the equation shown in the figure.

  The comparison results are shown as coordinates on the soft 10 key to which the soft 10 key comparison coordinates (x1 ', y1'), (x2 ', y2'), (x3 ', y3'), (x4 ', y4') belong. For example, the value (x12, y12) (here, the subscript “12” is set in four rows of 10 keys arranged as 1, 2, 3, 4, 5, 6, 7, 8, 9, 0) The second key of the first row (representing the numerical value “2”).

  The numerical value represents the comparison result as a numerical value, and is “2692” here.

  As described above, the card 34 is applied to an arbitrary position on the tablet 21 or the touch panel and, for example, a card is obtained by pressing a hole or hole, a notch or a mark in the lower left corner and the lower right corner first and second with a pen. Specify the origin (x00, y00) and other specific points (x01, y01) to virtually set the soft 10 key inside the system, and then cut holes, holes or holes of points No1 to No4 on the card 34 When the 3rd to 6th are sequentially pressed with a pen for the missing part or mark, the result is output as a numerical value, for example, “2692”.

  FIG. 25 shows a local ID authentication flowchart in the coordinate detection microcomputer of the present invention.

  In FIG. 25, step S201 determines whether the coordinate detection microcomputer 4 has input. If the determination result of step S201 is YES, the process proceeds to step S202. If the determination result in step S201 is NO, the process waits.

  In step S202, coordinates are detected. As shown in FIG. 26, which will be described later, this detects coordinates where a card 34 is placed on the tablet 21 and a hole or hole, notch or mark of the card is pressed with a pen.

  In step S203, it is determined whether the area is an ID authentication / input end area. In this step, it is determined whether the coordinate value detected in step S202 is a region where ID authentication starts or a region where input ends. If the determination result of step S203 is YES, the process proceeds to step S204. If the determination result in step S203 is NO, other processing is performed.

  In step S204, ID authentication processing is performed. This is based on the coordinate values detected in step S202, and based on the card origin (x00, y00) and other specific points (x01, y01) as shown in FIGS. 10 keys are virtually set inside the system, and then the third to sixth (x1, y1), (x2,. When y2), (x3, y3), (x4, y4) are sequentially pressed, the result is converted into a numerical value and key codes are sequentially transmitted.

  In this way, the coordinate detection microcomputer 4 side places the card 34 on the tablet 21 shown in FIG. 26 and designates the origin and other specific points by pressing down the holes, holes, notches or marks in the lower left corner and lower right corner with a pen. Then, the soft key is virtually arranged, and then the key code is converted into a numerical value based on these coordinate values by pressing the holes, holes, notches or marks of the four points card 34 of points No1 to No4 with a pen. Can be output locally (locally on the coordinate detection microcomputer 4 side).

  Step S205 performs password type security. As described above, this is a so-called password type in which a column of numerical values (0, 1, 2,... 9) converted to 10 keys in step S204 is compared with registered data to determine whether they match. Do security.

  In step S206, processing corresponding to the authentication result is performed.

  As described above, the origin (x00, y00) and other specific points (x01, y01) are input on a coordinate input device such as a tablet or a touch panel to virtually set the soft 10 keys, and the 10 key frame and 10 keys Both of them are hidden, the card 34 is applied, a hole or hole, a notch or a mark is pressed with a pen and coordinates are input, and based on the read coordinate value, which of the 10 keys is pressed is converted. After doing this locally on the coordinate detection microcomputer 4 side, the software on the CPU compares it with the registered data, and if it matches, the authentication is OK, and if it does not match, it is determined that the authentication is NG. It is possible to authenticate by inputting an arbitrary number string from a tablet or touch panel that cannot.

  FIG. 26 shows a definition explanatory diagram of ID authentication activation / ID input end of the present invention. Here, an ID authentication / input end area in the lower left corner is provided to instruct the start of ID authentication or the end of ID input in step S203 of FIG. 25 described above (details will be described later with reference to FIG. 27). Here, a specific area in the lower left corner on the tablet 21 or the touch panel is pressed with a pen to activate the ID authentication processing step S204 of the coordinate detection microcomputer 4. Next, the hole or hole, notch or mark in the lower left corner and lower right corner of the card 34 placed on the tablet 21 or the touch panel is sequentially pressed with a pen so that the card origin (x00, y00) and other specific points (x01, y01) is input, and the position of the card 34 is determined from the coordinate values and inclinations of the card origin (x00, y00) and other specific points (x01, y01). Subsequently, four holes or holes, notches or marks on the card 34 are sequentially pressed with a pen to input coordinates (x0, y0), (x1, y1), (x2, y2), (x3, y3). I do. And the specific area | region of the lower left corner on the tablet 21 or a touchscreen is pressed down again with a pen, and it notifies a microcomputer that ID input was complete | finished.

  FIG. 27 shows an end detection flowchart (when the order is asked) by inputting coordinates from a specific area on the tablet or touch panel of the present invention.

  In FIG. 27, step S211 determines whether the input is the nth time. In the example of FIG. 26 described above, this is determined as the fourth input corresponding to four coordinate input points. If the determination result of step S211 is YES, the process proceeds to step S213. If the determination result of step S211 is NO, the process proceeds to step S212.

  In step S212, it is determined whether the input is an end. This determines whether the coordinates in the end area of the lower left corner on the tablet 21 or the touch panel have been input. If the determination result of step S212 is NO, the process returns to step S211. If the determination result in step S212 is YES, the number of inputs and the number of registrations are compared in step S217, ID authentication output is output when they match in step S218, and mismatched output is output if NO.

  A step S213 saves the coordinates.

  In step S214, the input number and the registered number are compared.

  In step S215, it is determined whether the number of inputs exceeds the number of registrations. If the determination result in step S215 is YES, a mismatched output is made. If the determination result of step S215 is NO, the process proceeds to step S216.

  In step S216, the nth input is compared with the registered data.

  In step S219, it is determined whether or not the comparison result in step S216 matches. If the determination result of step S219 is YES, the process returns to step S211 and waits for the next input. If the determination result in step S219 is NO, a mismatch output is made.

  As described above, the end detection is not performed by the coordinate input from the specific area on the tablet 21 or the touch panel instead of the tie-out (YES in step S212). Outputs ID authentication, and outputs a mismatch when there is a mismatch.

  FIG. 28 shows an explanatory diagram for increasing the number of authentication IDs of the present invention. This is an example of registration data and has the following contents.

  In FIG. 28, point No. is the number given to the sequential input coordinates by pressing a hole or hole, notch or mark on the card in FIG. For convenience, for example, four of 1 to 4.

  The detected coordinates are the detected coordinates (x1, y1), (x2, y2), (x3, y3), (x4, y4) detected at points No1 to No4.

  The card position detection coordinates are based on the coordinate values of the card origin (x00, y00) and other specific points (x01, y01) at the lower left corner of the card input in FIG. The cos Δθ and the distance l0 were obtained as shown in the figure. The comparison coordinates (software 10 key comparison coordinates) are the card position detection coordinates for the coordinates (x1, y1), (x2, y2), (x3, y3), (x4, y4) of each point No1 to No4. Originally converted to the coordinate values (x1 ', y1'), (x2 ', y2'), (x3 ', y3'), (x4 ', y4') on the software 10 key by the formula shown in the figure is there.

  The registered coordinates are registered coordinates and correspond to the detected coordinates.

  This method does not use a soft key. In the case of 4 rows × 10 columns, in the soft 10-key method, an arbitrary key (number) is selected from each row one by one. Therefore, 10 4 = 10,000 ways. On the other hand, the method of the present invention removes one restriction from each row, the first input is an arbitrary one out of 40 holes, and the second input is an arbitrary one from the remaining 139 holes. 40 × 39 × 38 × 37 = 2, 193, 360 are selected. The reason why the point selected once is excluded is that there is a possibility that a plurality of the same coordinates may be inputted in the bound when the pen is pressed. The coordinate detection microcomputer outputs a separately registered key code when it is determined that the coordinates match as a result of comparison of the coordinates.

  On the other hand, four matrices of 10 soft keys of the present invention are virtually simultaneously displayed on the tablet 21 and the touch panel at the card origin (x00, y00) at the lower left corner of the card and other specific points (x01, y01) at the lower right corner. When set in correspondence, any four holes or holes, notches or marks in 4 rows x 10 columns are selected, so all IDs when entering a 4-digit decimal ID There are 40 × 39 × 38 × 37 = 2,193,360 combinations (the number of combinations of all IDs is 219 times as compared with the case of sequentially inputting using the conventional 10 keys). At this time, if a total of two points, one each for the card origin and other specific points, are used, the remaining number is 38, and the number of combinations of all IDs is 38 × 37 × 36 × 35 = 1,771,560. (The number of combinations of all IDs is 177 times that of the conventional case of inputting sequentially using 10 keys).

  As described above, the software 10 key is virtually hidden on the tablet 21 or the touch panel, and the card is applied to the tablet 21 to select any two points of the card (for example, the card origin (x00, y00) and two other specific points (x01, y01) at the lower right corner), and soft keys 10 are virtually set, and converted into numerical values based on the coordinate values that have been input. It is possible to increase the number of combinations of IDs several hundred times more than when inputting by pressing the 10 key, improving reliability and preventing theft of third parties. Become.

  FIG. 29 shows an application example (No. 1) of the present invention. An example in which the present invention described above is applied to a pen PC (pen input personal computer) will be described. Here, by placing a card (or ID card) 34 or the like on the screen 32 of the pen PC 31 and pressing the hole or hole, notch or mark with the pen 33, the transparent placed on the screen 32. In the case of a coordinate detector or electromagnetic induction system, the coordinates are detected by a non-transparent coordinate detector arranged below the screen 32, and authentication is performed in comparison with the ID registered as described above. Is possible. At this time, a card frame may be displayed on the screen 32, the card 34 may be placed in the card frame, and a hole, hole, notch or mark may be pressed with the pen 33, or the card frame may be displayed. Instead, a card frame or a soft 10-key frame based on the pressing of a predetermined first hole or hole, notch or mark of the card 34, or a plurality of holes or holes, notches or marks, etc. You may set virtually. In any case, the pressed coordinates are detected based on the displayed frame or a frame virtually set inside, and authentication is performed by comparing with the registered coordinates.

  FIG. 30 shows an application example (No. 2) of the present invention. A portable pen input computer 41 as shown in the figure has already been developed. For example, a display unit 42 made of a thin B5 or A4 size liquid crystal display panel is attached. By attaching a transparent touch panel (not shown) so as to cover the front surface of the display unit 42 and touching (lightly pressing) the touch panel with the input pen 43, the coordinates of the touched position can be detected. Here, the display unit 42 is a liquid crystal display, but the present invention is not limited thereto, and may be a plasma discharge panel or a CRT. Such a pen input computer 41 can have the above-described configuration of FIG. The present invention is applicable not only to the pen input computer 41 but also to various programmable devices having a coordinate detection device such as a word processor, an electronic notebook, a desktop device to which a coordinate detection device is connected, and a cash dispenser. The input method of the pen computer can be roughly classified into a resistance film method, an electrostatic coupling method, an electromagnetic induction method, and the like, but any input method may be used in the present invention. In the case of the electromagnetic induction method, coordinates are detected by sensing magnetism from a pen (or stylus) by a coordinate detector disposed below a screen (for example, a liquid crystal display). Furthermore, the present invention may be applied to a touch panel that has no pen input and is touched with a finger.

  In another embodiment of the present invention, a program for causing a computer to perform the user authentication method of the present invention as described above is stored in a computer-readable storage medium. That is, when the functions of the coordinate detection microcomputer 4 or the CPU 1 and the coordinate detection microcomputer 4 shown in FIG. A program for performing such a user authentication method is stored in a storage medium such as the CD-ROM 8a or the FD 9a. The storage medium is not limited to a CD-ROM or FD, but can store programs such as semiconductor storage devices such as ROM, EPROM, EEPROM, RAM, various disks such as optical disks, magneto-optical disks and magnetic disks, and card-like recording media. Any storage medium may be used.

  Next, a user authentication card according to the present invention will be described with reference to FIGS.

  FIG. 31 is a diagram showing a first embodiment of a user authentication card. In the drawing, the card 34-1 has a notch 341 in the upper right corner, and a hole or hole for inputting a user ID, a notch, a mark, or a punchable part described with reference to FIG. An ID input area 350 is provided. Thus, by making the shape of the card 34-1 asymmetric with respect to the top, bottom, left and right, the user can easily recognize the front and back and the top and bottom of the card 34-1 correctly. In the case of the card 34-1 shown in FIG. 31, when the user places the card 34-1 on the screen of the coordinate detector, the user must place the notch 341 so that it is at the upper right corner of the card 34-1. It is known beforehand. Therefore, when placing the card 34-1 on the screen of the coordinate detector, the user places the notch 341 at the upper right corner of the card 34-1 so that the front / back and top / bottom directions of the card 34-1 are aligned. It is automatically placed in the correct state, and it is possible to reliably prevent an erroneous input of the user ID due to an incorrect front / back and up / down direction of the card 34-1.

  In order to input a user ID or the like, it is only necessary to be able to specify coordinates, and it may be a hole that penetrates the card or a hollow that does not penetrate. That is, a hole, a hollow hole, a through hole, a mark printed by notch printing, a protrusion-like object, or the like may be used. Coordinate input devices used in pen computers include a resistive film method, an electrostatic coupling method, an electromagnetic induction method, and the like. For example, an electromagnetic induction method uses a pen (or stylus) by a coordinate detector disposed below the screen. Therefore, even if the pen does not directly touch the screen, the coordinate detector senses the magnetism and detects the coordinates. Therefore, in this case, what is provided in the card does not necessarily have to be a through-hole, but may be a depression, a hole, or a mark simply printed.

  FIG. 32 is a diagram showing a second embodiment of the user authentication card. As shown in FIG. 4A, a mark A 342 indicating a table is printed on the front surface of the card 34-2, and as shown in FIG. B mark 343 indicating the reverse side is printed. For example, the mark 343 on the back surface may be omitted, and the mark may be provided only on one of the front surface and the back surface of the card 34-2. Further, the marks 342 and 343 may be formed on the card 34-2 as a geometric shape change such as unevenness. An ID input area 350 provided with a hole or hole for inputting a user ID, a notch, a mark, or a punchable portion described with reference to FIG. 15 is provided at the center of the card 34-2. When the user places the card 34-2 on the screen of the coordinate detector, the user places the card 34-2 so that the mark 342 can be read as “A” in the correct orientation. Therefore, it is possible to reliably prevent an erroneous input of the user ID due to an incorrect front / back and up / down direction of the card 34-2.

  It should be noted that the ID input areas 350 of the cards 34-1 and 34-2 shown in FIGS. 31 and 32 are plural when a configuration in which coordinates can be input only when the screen is directly touched with a pen or the like is used. 15 is formed of a transparent member or an opaque member, although the card 34-1 and 34-2 are formed of a transparent member. Also good. On the other hand, the ID input area 350 of the cards 34-1 and 34-2 has a plurality of discontinuous holes or holes when a configuration is used in which coordinates can be input even if the screen is not directly touched by a pen or the like. The card 34-1 and 34-2 may be formed of a transparent member or an opaque member.

  FIG. 33 is a diagram showing a third embodiment of the user authentication card. In the figure, holes 344a and 344b are formed in the card 34-3 at positions asymmetric with respect to the top, bottom, left and right. An ID input area 350 provided with a hole or hole for inputting a user ID, a notch, a mark, or a punchable portion described with reference to FIG. 15 is provided at the center of the card 34-3. The holes 344a and 344b are used when data relating to the position of the card 34-3 is input to the coordinate detection microcomputer 4 as described with reference to FIG. Also, the hole 344a formed in the upper right corner of the card 34-3 can be used as a direction indicating means for the user to correctly recognize the front and back and the top and bottom of the card 34-3 as shown in FIG. 31 or FIG. Function. Thus, by making the positions of the holes 344a and 344b of the card 34-1 asymmetric with respect to the top, bottom, left and right, the user can easily recognize the front and back and the top and bottom of the card 34-3 correctly. In the case of the card 34-3 shown in FIG. 33, when the user places the card 34-3 on the screen of the coordinate detector, the user must previously place the hole 344a so that it is at the upper right corner of the card 34-3. Be informed. Accordingly, when the user places the card 34-3 on the coordinate detector screen, the user places the hole 344a at the upper right corner of the card 34-3. Therefore, it is possible to reliably prevent an erroneous input of the user ID due to an incorrect front / back and up / down direction of the card 34-3.

  FIG. 34 is a diagram showing a fourth embodiment of the user authentication card. In the figure, on the card 34-4, marks 345a and 345b are formed as prints or geometric changes at positions asymmetric with respect to the top, bottom, left and right. An ID input area 350 provided with a hole or hole for inputting a user ID, a notch, a mark, or a punchable portion described with reference to FIG. 15 is provided at the center of the card 34-3. The marks 345a and 345b are used when data related to the position of the card 34-4 is input to the coordinate detection microcomputer 4 as described with reference to FIG. Further, the mark 345a formed at the upper right corner of the card 34-4 can be used as an orientation instruction means for the user to correctly recognize the front and back and the top and bottom of the card 34-4 as shown in FIG. 31 or FIG. Function. Thus, by making the positions of the marks 345a and 345b of the card 34-4 asymmetric with respect to the top, bottom, left and right, the user can easily recognize the front and back and the top and bottom of the card 34-4 correctly. In the case of the card 34-4 shown in FIG. 34, when the user places the card 34-4 on the screen of the coordinate detector, the user must previously place the hole 345a so that it is at the upper right corner of the card 34-4. Be informed. Accordingly, when the user places the card 34-4 on the screen of the coordinate detector, the user places the card 345a so that the mark 345a is at the upper right corner of the card 34-4. Therefore, it is possible to reliably prevent an erroneous input of the user ID due to an incorrect front / back and up / down direction of the card 34-4.

  Note that the ID input area 350 of the card 34-3 shown in FIG. 33 has a plurality of discontinuous holes or holes when a configuration in which coordinates can be input only when the screen is directly touched with a pen or the like. The card 34-3 may be formed of a transparent member or an opaque member. On the other hand, the ID input area 350 of the card 34-4 shown in FIG. 34 has a plurality of discontinuous holes or holes when a configuration is used in which coordinates can be input even if the screen is not directly touched by a pen or the like. The card 34-4 may be formed of a transparent member or an opaque member.

  Further, when the position marker displayed on the screen is displayed within the outer shape of the card, it is desirable to form the card with a transparent member. In this case, since the displayed position marker is seen through the card, the hole or hole, notch or mark provided on the card is moved to the position marker while moving the card on the screen with respect to the displayed position marker. Easy to match the position.

  Furthermore, it goes without saying that various embodiments of the card may be arbitrarily combined, and the hole or hole, notch, mark and / or punchable part may be mixed in the card.

  While the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications and improvements can be made within the scope of the present invention.
