JP4679045B2 - Passcode input method and electronic device to which this method is applied - Google Patents

Description

  The present invention relates to a passcode input method and an electronic apparatus to which this method is applied.

  Conventionally, in an information processing apparatus such as a personal computer or a specific office machine such as a projector, the use of a password (hereinafter, more generally referred to as “passcode”) is permitted only when it is properly entered. Configured to be. This is for ensuring security of information and responding to requests for management of the device or device. It is also already known to use a pointing device such as a mouse for inputting a pass code to such an apparatus or device (for example, Patent Document 1).

  In addition, the password formed by combining mouse button clicks is registered, and when the information processing apparatus is turned on, the passwords formed by clicking a plurality of buttons are entered. If the result of verification and verification does not match, the mouse operation is prohibited, the serial number of the information processing device is registered in the mouse by the information processing device, and the password verification result by the password verification unit matches When the registered serial number is collated and verified, the information processing device is prohibited from operating if it does not match, thereby preventing misuse of the device without requiring complicated control with a simple operation. The security guard can be applied to the mouse as much as possible. Serial number does not match, thereby also been proposed technologies that made it possible to apply a security guard to the information processing apparatus (Patent Document 2).

  Furthermore, a password input device using a pointing device that checks the security by clicking the button on the pointing device and recognizes the number of clicks as a password, and outputs a startup notification when the power is turned on. A pointing device that detects whether the button of the pointing device is pressed, outputs a detection signal, and outputs movement information of the pointing device movement direction and movement distance at fixed intervals, and recognizes a password A password storage device for storing a security function program and a preset password; a storage device for storing an operating system, an application program and data; and the password storage device upon receipt of the activation notification from the power switch The security function program is read and executed to prompt a password input request, the time interval of the detection signal output when the button is not pressed from the pointing device, and the number of clicks is recognized as a password. A password input device using a pointing device is also disclosed, which includes a CPU that checks the validity of the password by comparing it with a preset password (Patent Document 3).

  In addition, in order to enter a password using a mouse that is a pointing device, a screen for entering a password is displayed on the display unit via the control unit, and this screen is used to enter a password under the user name. The display buttons for input are displayed, and when the cursor is positioned with the mouse in the area of the display buttons, the combination of the operation state and the display button is determined in advance by clicking the mouse operation key. There has already been proposed a technique for reducing the burden on a user unaccustomed to inputting a personal identification number using a keyboard by inputting the password information (Patent Document 4).

  Further, one password is selected from a plurality of user-specific passwords stored in advance according to the user's instruction, and a message prompting the user to input the password is displayed to the user. When the designated password is input in response, the entered number is compared with the selected password, and if the two match, it is determined that the correct password has been entered. Since one password is selected from a plurality of passwords according to the user's instruction, the security code to be input is changed from time to time so that high security can be obtained and the operation performed by the user Has only been required to input one type of password, and a technique has been proposed in which the input operation is simplified (Patent Document 5).

  Furthermore, a point on a specific image is input from the pressure-sensitive tablet, and the coordinates of the point on the input image are stored in the RAM in the input order, and the coordinates matching the stored contents of the RAM are stored in the RAM. Only when all data is input in the same order as the stored contents, the specified data can be read and written, and data can be protected and released by a simple input method. A technique to be attempted has also been proposed (Patent Document 6).

Also, the time series pattern of multiple on operations of the two input operation keys of the mouse is stored in the correct password memory so that the length of each on operation time can be understood, and each on-off of the judgment password to be input The CPU compares the length of the operation time with the correct password and compares the length of the on-operation time to determine personal authentication. A technique for enhancing the confidentiality of a password by being incorporated as a determination element has also been proposed (Patent Document 7).

  However, as is well known from Patent Document 1, when a pointing device such as a mouse is used to input a passcode, registration is further performed even when the password verification result matches as disclosed in Patent Document 2. In the method of permitting use of the information processing apparatus by checking the serial number, there is an inconvenience such that the user cannot use it when the mouse is replaced. In addition, since the password input device such as Patent Document 3 employs a method of counting the number of clicks and confirming the input according to the length of the time interval of the click operation, it is possible to input a passcode with only a mouse button. However, the user who performs an input operation needs to recognize in advance a sense of the predetermined elapsed time. On the other hand, the password input method using the combination of the display button displayed on the screen and the left and right click buttons of the mouse as in Patent Document 4 remembers the correspondence between the display button on the screen and the left and right click buttons of the mouse. You must enter your password and be proficient. Furthermore, in the method as disclosed in Patent Document 5, it is necessary to hesitate to input a personal identification number using a numeric keypad, which is a heavy burden for a user who is not familiar with key operations. Further, the method of inputting a point on a specific image using a pressure-sensitive tablet as in Patent Document 6 requires further learning and is difficult for beginners to handle. Furthermore, although the method of incorporating an element that cannot be easily grasped by a person such as a key-on operation time as disclosed in Patent Document 7 has high secrecy, a very high level of skill is required for the user.

  Accordingly, an object of the present invention is to provide a passcode input method that is easy to operate and has high confidentiality, and an electronic apparatus to which this method is applied.

  According to the present invention, a passcode input method that is easy to operate and highly confidential, and an electronic device to which this method is applied are realized.

  Hereinafter, preferred embodiments of a passcode input method of the present invention and an electronic apparatus to which the method is applied will be described in detail.

  FIG. 1 is a flowchart showing a passcode input method as an embodiment of the present invention, FIG. 2 is a block diagram for conceptually explaining functions related to an electronic device to which the passcode input method of FIG. 1 is applied, and FIG. FIG. 4 is a diagram for explaining an example of a scene where the present invention is implemented, and FIG. 4 is a diagram for explaining an example of a scene where the present invention is implemented in a system connected by a network.

  In the scene where the present invention illustrated in FIG. 3 is implemented, a system having a security function using a pass code (password) is configured for the projector 1 that does not include a keyboard as an electronic device. The projector 1 is operated by being functionally coupled with a mouse 2 as a pointing device or a remote controller 3 by a wired or wireless function, and projects an image on the screen 4. As shown in the figure, a screen display 5 of the passcode input status is possible on the screen 4. In this example, as a pass code to be input using the mouse 2 or the remote controller 3, a pass code (password) based on a combination of numbers that can be easily remembered by the user as compared with a specific pattern method (including operation by time timing) is used. The method is applied.

  In a conventional general system equipped with an input device such as a keyboard or numeric keypad as a means for inputting a passcode number, a passcode can be easily input. In a system that does not, it is difficult to input, and when a passcode input status is displayed on the screen 4 to input numbers from an input device such as a mouse or a cursor key, the screen is viewed by a third party. However, as described in detail below, the present invention eliminates such a problem.

  In a system in which a pass code is input to a projector 1 that does not have a keyboard similar to that in FIG. 3 using the mouse 2 or the remote controller 3, as shown in FIG. It is also possible to adopt a mode in which authentication is performed by inputting a passcode having the same contents as the passcode (set in the projector as the electronic device) input using. In this case, since the pass code can be easily set by inputting a number using the personal computer 6, there is an advantage that the user can easily memorize the pass code by using the pass code formed by numbers. It should be noted that when the passcode authentication is connected to the personal computer with another system terminal connected to the network, the contents of the passcode require the same numeric code.

  3 and 4, even when the system does not have a keyboard for inputting a passcode, the passcode input status by operating the mouse 2, the remote controller 3, or the key on the main body is displayed on the screen 4. However, on the screen, for each operation on one operation part (for example, the left click button of the mouse 2, the remote controller 3 or a specific operation part of the main body) for performing an operation for representing each digit of the passcode. On the other hand, a predetermined display pattern or symbol (in this example, an asterisk: *) is displayed, and the same display pattern or symbol is also displayed for an operation on the other operation unit of the remote controller 3. Therefore, even if viewed by a third party, the confidentiality of the passcode contents is maintained.

  FIG. 2 conceptually explains each function in the apparatus of the present invention to which a mouse having click buttons as two left and right operation units as a pointing device used functionally connected to the projector 1 as an electronic apparatus main body is applied. It is a block diagram for doing.

  In FIG. 2, an operation on a mouse as a pointing device is supplied to the mouse interface unit 20 as mouse information generated by this operation, and is separated into left click information and right click information.

  Once the repetition of the click operation (including the case where the number of operations is one) of the one operation unit (left click button in this example) among the click buttons of the mouse is started once A series of operations (left) defined in each section defined by dividing each section until the end by a predetermined operation (click operation) on the other operation unit (right click button in this example). The counter 21 is an element constituting the repetition number recognizing means for recognizing the repetition number of the click), and each digit of the count value in the counter 21 which is the repetition number recognized by the repetition number recognition means is the electronic device. Each digit corresponding to the passcode held in the passcode holding circuit 23 holding the passcode relating to the projector is compared with the comparison circuit 2. In are respectively compared.

  The comparison circuit 22 constitutes a component of determination means for determining the appropriateness of the input of the passcode by the pointing device (mouse) based on the comparison result. The determination result of suitability is sent as passcode authentication information to the publicly known control unit itself which is not shown through the transmission path 24. When the processing in the comparison circuit 22 is completed, counter reset information is supplied from the circuit 22 to the counter 21 and the count value is reset.

  FIG. 5 is a conceptual diagram showing the configuration of the projector 1 of the system shown in FIG. In FIG. 5, information from a remote control receiver 11 that receives a command sent from the mouse 2 or the remote controller 3 as a pointing device is supplied to a controller 12 having a CPU as a main component, The control unit 12 executes predetermined processing based on the supplied information, and sends necessary data to the display unit 13 for performing a desired display by this apparatus. On the other hand, the control unit 12 is configured to exchange required information with the RAM 15 and the ROM 16 through the bus 14.

  FIG. 6 is a conceptual diagram showing the configuration of the projector 1 of the system shown in FIG. In FIG. 6, the control unit 12 is connected to a network interface 17 for exchanging information with an external network, but the other configuration is exactly the same as that described above with reference to FIG.

  Next, an embodiment of the method of the present invention (operation of the electronic device) will be described using the flowchart of FIG. First, the failure counter is cleared (reset) in a state where the passcode can be input (S11). This failure counter is a counter for measuring the number of times that re-input is permitted when the user erroneously inputs a passcode. Here, an example is shown in which the input is automatically terminated when an input mistake occurs three times. However, the number of times the re-input is allowed is set to a value of the counter set value (S20) at an arbitrary N times. It is possible.

  When the failure counter is cleared (reset) (S11), a counter buffer clear operation is then performed (S12). This resets the set value (S21) to the counter buffer for temporarily holding the input passcode. Thereafter, a click detection operation for waiting for a click input is started (S13). In this detection, an input of a left click or a right click of the mouse is detected to determine which operation to be described later is performed. If a left click is detected, the counter is incremented (counted up) (S15), and the process proceeds to the next click detection (S13). This count-up is for detecting how many times the left click is clicked. In the button detection (S14), a button such as a confirmation key (right click operation) is detected. If it is a confirmation key (S16), the current confirmation key (right click operation) is changed from the previous confirmation key (right click operation). The series of the number of operations of the left click in the operation section up to (operation) is collated with the corresponding digit of the passcode (S17).

  If the passcode matches the value held in the passcode verification buffer, it is determined that the passcode matches and the security is released (S18). If they do not match, the failure counter is incremented and the number of failures is counted (S19).

  If the value of the failure counter becomes a preset value, it is determined that there is a continuous passcode input error (S20), and the passcode input process is terminated (S23).

  When a right click is detected in the above click detection (S13), it is determined that the input value of one character is confirmed, and the value is stored in the passcode verification buffer (S21), and left click is used. The counter is reset (S22).

  By this series of operations, the number of one character of the passcode is input with the left mouse button, and the value is determined by right-clicking. In other words, the sections from the start to the end of the repetition of the left-click operation of the mouse, which is the pointing device (including the case where the number of operations is one), are each on the right. Recognizes the number of repetitions of a series of operations within each section defined by being divided by a click operation, and relates to the number of repetitions of the left click operation within these sections and the electronic device (projector). Each passcode is compared with each corresponding digit, and based on the result of the comparison, whether or not the passcode is input by the mouse is determined.

  Next, FIG. 7 and FIG. 8 are flowcharts showing an operation method when an input corresponding to a number is performed by a click operation on the mouse. A method of using numbers “0” to “9” and two types of input methods using numbers “1” to “9” as input passcodes (passwords) will be described.

  FIG. 7 is a flowchart showing an operation method when “0” to “9” are used for the input passcode. This corresponds to input of the pass code “1” for one left click. That is, in order to input the pass code “2”, the left click may be performed twice in succession. If a number corresponding to the corresponding digit of the passcode is input by the number of left clicks, it may be confirmed by right clicking (once). By repeating this operation, all digits of the passcode are input. By pressing the confirm button after the end of this series of operations, the passcode is verified.

  FIG. 8 is a flowchart showing an operation method when “1” to “9” are used for the input passcode. This corresponds to input of the pass code “1” for one left click. That is, in order to input the pass code “2”, the left click may be performed twice in succession. If a number corresponding to the corresponding digit of the passcode is input by the number of left clicks, it may be confirmed by right clicking (once). By repeating this operation, all digits of the passcode are input. By clicking the right button again after the end of this series of operations, passcode verification is executed. In the above method, since the pass code “0” is not permitted in advance, the right button can be continuously input.

  FIG. 9 is a diagram for explaining another passcode input operation example configured using “0” to “9” as in FIG. 7. As shown in the figure, input operation examples of pass codes “1234”, “0234”, and “1340” are shown. Similarly, FIG. 10 shows a passcode input operation example similar to FIG.

  That is, FIG. 10 is a diagram showing the input operation of the passcode “1234” configured using “1” to “9” described above with reference to FIG. 8 by the same notation method as FIG. .

  FIG. 11 is a diagram illustrating a display example when the input operation status of the passcode configured using “0” to “9” is displayed on the display screen. As shown in the figure, one display of the same asterisk “*” appears corresponding to each click operation, regardless of whether the mouse left-click operation or right-click operation, and expresses the passcode itself. Not shown in numbers.

  FIG. 12 is a diagram illustrating a display example when the input operation status of the passcode configured using “1” to “9” is displayed on the display screen. In this case, since “0” is not used for the passcode, the confirmation can be performed by right-clicking. Regardless of whether the mouse left-click operation or right-click operation is performed, one display of the same asterisk “*” appears corresponding to each click operation, and it is not shown in the figure representing the passcode itself. This is the same as the case of 11.

  In any of the screen displays of FIGS. 11 and 12 described above, the passcode itself is not directly expressed directly, so that the confidentiality of the passcode is maintained. In addition, not all digits of the numeric passcode are displayed, but some of the keys (operations corresponding to the pointing device other than the mouse or the corresponding operation unit when using a remote control) are used (by entering the passcode digits). A method of scrolling the display part according to the progress of the input of each digit may be applied to all digits of the passcode. Visibility may be improved by flushing “*” in the display area. In these cases, even the number of digits of the pass code does not become apparent, and the secrecy of the pass code is more fully maintained.

  According to the embodiment of the present invention described above, a passcode can be easily input by an input means such as a mouse, a remote controller, an operation unit of an electronic device main body, etc. without using a numeric input device such as a keyboard. Moreover, even if the input action is output on the screen, there is no possibility that the passcode is read by a third party. Even when there is no screen output, it is possible to input a passcode.

  In addition to the input method using the mouse, the input method using the remote controller, and the input method using the keys on the operation unit main body of the electronic device main body, the same operation format and display are used in the input method using appropriate means different from these. It is possible to input in the form, and in any case, the efficiency of the user interface is improved as in the case described above. In addition, since numerical input can be used for the passcode, there is an advantage that the user can easily memorize it in the form of a password. Furthermore, since the number of words (number of digits) of the passcode can be set arbitrarily, the parameters increase if the number of digits to be input is increased. Therefore, the entire picture of the passcode becomes difficult to grasp and the confidentiality is improved.

  FIG. 13 is a diagram showing a mouse as an example of a pointing device applicable to the implementation of the present invention. In the above-described example, the number of clicks with the left button 111 of the mouse is set as the passcode value and is confirmed by the click operation of the right button 112. However, the functions of the left and right click buttons are reversed, The same passcode input operation as described above is possible even if the number of clicks is set as the passcode value and confirmed by clicking the left button 111.

  FIG. 14 is a diagram showing a remote controller 120 that can function as a device equivalent to the pointing device applied in the above-described embodiment of the present invention. An operation for performing the above-described left click on the mouse on a part of the direction key 121 of the remote controller 120 (for example, a right operation part or an upward operation part) and another part (for example, a left operation part or a downward operation part), respectively. By assigning it as an operation unit for performing a right click, it is possible to perform a passcode input operation in the same manner as in the case of using the mouse illustrated in FIG. It should be noted that the present invention can also be implemented by appropriately assigning the operation unit or the plurality of operation units provided in the electronic device main body as an operation unit that performs a left click of the mouse and an operation unit that performs a right click as described above.

  All of the above are examples in which a passcode input operation is performed by clicking or pressing any operation unit, but the mode of operation is not limited thereto. For example, a passcode input operation can also be performed by a mouse movement (gesture) operation in the same manner as described above.

  15 and 16 are diagrams for explaining a method of performing a passcode input operation by a mouse movement (gesture) operation. In this method, a gesture operation of a predetermined form performed on the mouse (in the example of FIG. 15, a movement operation from the lower left to the direction of 45 degrees diagonally upward to the right; Each movement operation (in the direction of 45 degrees and in the direction of 45 degrees obliquely from the upper right to the lower left) is started (including the case where the number of gesture operations is one). Each section from the first to the end is a gesture operation in another form (moving operation from the upper right to the direction of 45 degrees diagonally to the left in the example of FIG. 15: from the upper left to the diagonally lower 45 in the example of FIG. A series of gesture operations in each section defined by being divided by respective movement operations) in the direction of degrees and in the direction of 45 degrees from the lower right to the upper left diagonal direction. Corresponding number of times passcode Recognized as a digit.
