Description

The present invention is a portable information processing apparatus such as a cellular phone, a PDA, or a method of controlling及beauty programs.

  Conventionally, a portable information processing apparatus capable of setting a password is known. This type of portable information processing apparatus is configured such that when the input value and the password do not match, a specific application cannot be started or the apparatus itself cannot be operated.

  Here, a four-digit code is generally registered as a password, and since a birthday or a telephone number is often used, it is often mistaken for a third party and used illegally. In order to solve this, it is conceivable to increase the number of digits of the code constituting the password. However, although the input operation to the apparatus is not complicated, there is a problem that it is difficult for the user to memorize the password and an input error is likely to occur.

  Therefore, a password verification system has been proposed that can improve confidentiality with a simple operation without increasing the number of digits of the password (see Patent Document 1).

  This password verification system includes a registration unit 38 for registering a password input from the key button unit 39 and password reception time data for accepting the password, a display unit 36 for displaying the current time, and a user to any time. A clock setting unit 40 for easily changing and returning the setting to the current time, and an input analysis unit 37 for analyzing whether the password input from the key button unit 39 matches the registered password. I have.

  The password input from the key button unit 39 is registered in the registration unit 38 as password data. At this time, the time displayed on the display unit 36 is registered in the registration unit 38 as password reception time data. When the password data is registered in the registration unit 38, the password reception time data is recorded in a memo pad or the like, and the next time the password is input, immediately before that, the clock setting unit 40 is recorded at the time recorded in the memo pad or the like. change.

  When the password is input, the input analysis unit 37 determines whether the current time coincides with the password reception time data for each digit input. Therefore, the password verification system can release the confidentiality of the password by inputting the password by matching the clock with the password reception time data at the time of registration (paragraphs “0035” to “0042” of Patent Document 1). ).

  Further, an authentication system that authenticates a user without depending on a password has been proposed (see Patent Document 2).

  In this case, the user selects a corresponding combination of key input and output in advance from an existing table or arbitrarily sets it according to his / her preference and registers it as an authentication setting table in the authentication apparatus.

For example, the output is “I” for the key input “yi”, the output “O” for the key input “oo”, the output “Katakana” for the key input “Ctrl + I”, and so on. And register. Regardless of user authentication by password at power-on startup, the combination of subsequent key input and output is monitored, and when the key input is in the registered authentication setting table, the output is not in the authentication setting table When the number of times exceeds a predetermined number, it is determined that key input by an unauthorized user is performed, and error processing is performed (FIGS. 5 and 9 and abstract of Patent Document 2).
JP 2003-58505 A JP 2002-91670 A

  However, in the password verification system of Patent Document 1, since it is necessary to record this password reception time in a memo pad, an opportunity to be seen by a third party is created and the security effect is reduced. On the other hand, if the user memorizes the time without leaving it in the memo pad, it is equivalent to increasing the number of digits of the password and memorizing the second password, which is a burden on the user. In addition, since an operation for setting a clock is required before input, the input operation is not necessarily simple.

  In addition, when the authentication system of Patent Document 2 is applied in combination with password input in order to improve confidentiality without increasing the number of digits of the password, the user needs to store a corresponding combination of key input and output. Therefore, when only characters that do not record this combination are input as a password, the effect cannot be expected. On the other hand, if a large number of combinations are registered in order to avoid this, the user needs to memorize a large number of combinations, which increases the burden on the user and increases the possibility of an input error. . As a result, the input operation is not easy.

  In this way, any system requires time recording and registration operations, or needs to store and operate a special input method, so that a portable type that requires a particularly simple input operation is required. It is not suitable for authentication of information processing devices.

Accordingly, an object of the present invention is to provide a password obtained by converting a password input in accordance with an operation by a user in order to enable authentication while ensuring security with a simple operation.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing the overall configuration of a portable information processing apparatus according to an embodiment of the present invention.

  1 includes a CPU 101, a storage device 102, a recording medium 103, a transmission device 104, a power supply device 105, an input device 106, a power switch 106a, a peripheral device connection device 107, a printing device 108, and a display device 109. And a sound device 110. The peripheral device connection device 107 is connected to the printing device 108.

  The CPU 101, the storage device 102, the transmission device 104, the power supply device 105, the input device 106, the peripheral device connection device 107, the display device 109, and the sound device 110 are connected to each other via a system bus 120.

  The CPU 101 is a central processing unit that controls main operations of the portable information processing device 100 in accordance with an operating system and various application software in the storage device 102. Further, the CPU 101 reads the current date and time (YYYYMMDD HHMM) from the system clock of the operating system of the storage device 102.

  The storage device 102 stores a registered password, terminal identification information (serial number), and the like set in advance for user authentication in addition to an operating system and various application software, and is configured by a magnetic, optical, semiconductor memory, or the like. The recording medium 103 may be a portable medium such as a card. The program and data stored in the recording medium 103 are loaded into the storage device 102 under the control of the CPU 101 as necessary, and the data in the storage device 102 is saved in the recording medium 103.

  Further, the CPU 101 can also fetch a part or all of the programs and data stored in the recording medium 103 from another device (not shown) via the transmission device 104 and newly register or add to the recording medium 103. . Furthermore, the program and data may be stored and managed by an external device (not shown) such as a server. The CPU 101 can also directly access and use a program and data of an external device (not shown) via the transmission device 104.

  On the other hand, a printing apparatus 108 is connected to the CPU 101 via an input device 106, a display device 109, and a peripheral device connection device 107, which are input / output peripheral devices. The input device 106 includes a key and a touch panel for receiving data input, and a power switch 106 a that turns on and off the power device 105. When the power switch 106a is turned on, driving of various devices such as the CPU 101, the display device 109, and the sound device 110 is started. When the power switch 106a is turned off, the CPU 101, the display device 109, the sound device 110, and the like are driven. The driving of various devices is stopped.

  The display device 109 is configured by a touch panel screen, and the sound device 110 reproduces sound data stored in the storage device 102 or the recording medium 103 and generates a sound such as a song, a ringtone, or a warning sound.

  FIG. 2 is a flowchart showing processing from user power-on of the portable information processing apparatus 100 to user authentication until a predetermined application is activated.

  When the power switch 106a is turned on, the CPU 101 performs a password input process (step S201). This process accepts input of a code having a predetermined number of digits from the input device 106.

  Next, the CPU 101 calls a password registered in advance from the storage device 102, executes password analysis processing (step S202) for comparing with the code input in step S201, and determines whether or not the passwords match. A process (step S203) is executed.

As a result of the determination in step S203, the CPU 101 activates a predetermined application if the input code and the registered password match, but if the input code and the registered password do not match, A preset error handling process is executed (step S204). As the error handling process, for example, a warning is displayed to the user for a certain period of time when “the password is wrong” on the display device 109, and the input of the password is awaited again. After treatment of this for Step S20 4, the flow returns to step S201.

  The error handling process is not limited to the above method, and subsequent input processes may not be accepted, or the portable information processing apparatus 100 may be turned off.

  FIG. 3 is a flowchart showing in detail the password input process in step S201 of FIG. It is assumed that a password for user authentication is recorded in advance in the storage device 102 or the recording medium 103 and can be recalled to the storage device 102 when necessary. All processes are executed by the CPU 101 of the portable information processing apparatus 100.

  When the power of the power supply device 105 is turned on, the password input process is started. First, the timing (X) for changing the input mode to the password input is set (step S301). Here, “timing to be changed during password input” refers to timing for designating how many digits of the password should be changed after the password is input. Note that the password input process is triggered not only when the power of the power supply device 105 is turned on, but also when returning from the suspended state, when no operation is performed for a certain period of time, or when accessing personal information or processing for the administrator. It may be an operation or the like. Here, the timing (X) is the number of digits of the password. For example, if the password is a 4-digit code and 2 digits are set as the timing (X), the input mode is changed when the upper second digit is input. Further, as a method of setting the timing (X), for example, there is a method of calculating the timing (X) from the current time based on a predetermined calculation formula. This will be described later with reference to FIG. Note that the user may set the timing (X) from the input device 106.

  Next, in order to prompt the user to input a password, a password input screen is displayed on the display device 109 (step S302), a variable n indicating the number of input digits is initialized (step S303), and the variable n is set. Increment by 1 (step S304).

  It is determined whether or not the variable n exceeds a preset maximum number of digits (for example, 4 digits) (step S305).

  If the variable n exceeds the maximum number of digits as a result of the determination in step S305, the password input process is terminated. If the variable n is within the maximum number of digits, the nth digit password is input from the input device 106. Acceptance (step S306) and the input digit are displayed on the display device 109 (step S307).

  Next, it is determined whether or not the input digit is the input mode change timing (n = X) (step S308). If the input digit is not the input mode change timing, the process returns to step S304 to proceed to the password processing for the next digit. At this time, the input digit is the input mode change timing (n = X). In this case, the input mode change display is performed (step S309), and the next input from the input device 106 is accepted (step S310).

  It is determined whether or not the input code matches the input mode return instruction data registered in the storage device 102 in advance (step S311).

  As a result of the determination in step S311, if the code input in step S310 matches the input mode return instruction data registered in advance in the storage device 102, processing for returning to the normal input mode is executed ( In step S312), the process returns to step S304 to proceed to the password processing for the next digit.

    As a result of the determination in step S311, if the code input in step S310 does not match the input mode return instruction data registered in advance in the storage device 102, the n-th digit data cannot be input from the input device 106. The code value is converted into data such as a pictograph, an external character symbol, a Marlett symbol, or a Wingdings symbol (step S313), the variable n is incremented by 1 (step S314), and the process returns to step S304. Proceed to the password input process. In step S313, the data is converted into data that cannot be input. However, the data may be converted into data different from the code (data) input in step S310.

  Thereafter, the process from step S304 to step S314 is repeated until the maximum number of digits of the password (for example, 4 digits) is input, and when the input of the code for the maximum number of digits (for example, 4 digits) is completed, the password input process ends. To do. The codes of all the digits (for example, 4 digits) input in this process are sent to the next password analysis process (step S202).

  FIG. 4 is a flowchart showing processing for setting the timing (X) for changing the input mode. All processing is executed by the CPU 101 of the portable information processing apparatus 100.

  First, the current date and time (YYYYMMDD HHMM) is read from the system clock of the operating system of the storage device 102 (step S401). Next, the read values are added and divided by 4 to obtain a remainder (step S402). The value (remainder) calculated here is set as the input mode change timing, recorded in the storage device 102 (step S403), and the process is terminated. Step S401 may generate and calculate a random number.

  In step S402, the read values are added and divided by 4, and the remainder is obtained. This is applied when the password is 4 digits, for example, when the password is 5, 6,. Respectively add the read values and appropriately divide by 5, 6,... Corresponding to the number of digits of the password to obtain the remainder.

  Next, FIG. 5 is a diagram for explaining password input processing using a display screen on the display device 109, and shows an example in a case where appropriate password input is executed.

  Here, it is assumed that the password is registered in the storage device 102 as “1234” in advance, and the timing (X) for changing the input mode is the second digit.

  The password is not limited to four digits, and a code other than a numerical value may be used. Also, the input mode return instruction data necessary for the input mode return processing in step S312 of FIG. 3 is registered as an input signal from the touch panel screen of the display device 109. Therefore, an input signal is sent to the CPU 101 by touching the touch panel screen of the display device 109 during the input mode return processing. The input signal is not limited to the input signal from the touch panel screen, and may be input of a numerical value or a symbol or a function key.

  In FIG. 5, screen (i) is the display screen in step S302, and displays general information such as the name and date of the application software to be started later, and prompts the user to input a password. The background color of the screen is assumed to be white, for example.

  On the screen (ii), when “1” is input from the user in step S306, a symbol (“*” in FIG. 5) representing the first digit is displayed (step S307), and the input mode change timing (n = X) is determined (step S308), but since it is not the input mode change timing, the process returns to step S304 and proceeds to the password entry process for the second digit.

  On the screen (iii), when “2” is input from the user in step S306, a symbol representing the second digit (“**” in FIG. 5) is displayed (step S307), and the input mode change timing (n = X) (step S308), but this time is the input mode change timing, so changing the background color of the screen (for example, white to green) displays the input mode change. Is performed (step S309). Thereby, the user can understand that the input mode has been changed. The means for notifying the user that the input mode has been changed in step S309 is not limited to changing the background color of the screen, and may be a display of characters, icons, or images, instead of the display. In addition, sound may be generated by the sound device 110, vibrated by a vibration device (not shown), or a combination thereof. Further, the notification content may be the content of the content for the purpose of threatening effect, or the content of the notification that is difficult to be noticed by non-regular users.

  Here, when the input signal from the touch panel screen is received by waiting for the next input from the user and the user touching the touch panel, an input mode return process for returning to the normal input mode is executed ( Step S312), screen (iv) is displayed.

  Thereafter, the process returns to step S304 again, and proceeds to the password entry process for the third digit as shown in the screen (v). When “3” is entered, a symbol representing the third digit (“***” in FIG. 5). Is displayed (step S307), and it is determined whether or not it is the input mode change timing (n = X) (step S308), but since it is not the input mode change timing, the process returns to step S304 and the fourth digit password is input. Proceed to processing.

  When “4” is further input, a symbol representing the fourth digit (“***” in FIG. 5) is displayed (step S307), and it is determined whether or not it is the input mode change timing (n = X). However, since it is not the input mode change timing, the process returns to step S304. Here, since the 4-digit input has already been completed, the password is stored as “1234”, and the password input process is terminated (screen (vi)).

  Next, the password analysis process in step S202 of FIG. 2 is executed. If the passwords match, a predetermined application is activated, and the display device 109 displays, for example, a screen (vii).

  FIG. 6 is a diagram for explaining password input processing using a display screen on the display device 109, and shows an example when an inappropriate password input is executed (for example, when an unauthorized user performs an erroneous operation). .

  As in FIG. 5, it is assumed that the password is previously registered in the storage device 102 as “1234”, and the timing (X) for changing the input mode is the second digit.

  Screen (i) is a display screen in step S302, and displays general information such as the name and date of application software to be started thereafter, and prompts the user to input a password. The background color of the screen is assumed to be white, for example.

  On the screen (ii), when “1” is input from the user in step S306, a symbol representing the first digit (“*” in FIG. 6) is displayed (step S307), and the input mode change timing (n = X) is determined (step S308), but since it is not the input mode change timing, the process returns to step S304 and proceeds to the password entry process for the second digit.

  On the screen (iii), when “2” is input from the user in step S306, a symbol representing the second digit (“**” in FIG. 6) is displayed (step S307), and the input mode change timing (n = X) (step S308), but this time is the input mode change timing, so changing the background color of the screen (for example, white to green) displays the input mode change. Is performed (step S309). Thereby, the user can understand that the input mode has been changed.

  Here, for example, when “3” is input without waiting for the next input from the user and the user touching the touch panel, the input value “2” in the second digit cannot be input from the input device 106. Value, for example, an external character symbol (step S313), the variable n indicating the number of digits is incremented by 1 (step S314), the third digit input data is stored as "3", and the third digit (“***” in FIG. 6) is displayed (screen (iv)), and the process returns to step S304 to proceed to the password input process for the fourth digit.

  When “4” is further input on the screen (v), a symbol representing the fourth digit (“***” in FIG. 6) is displayed, and whether or not it is the input mode change timing (n = X). Is determined (step S308), but since it is not the input mode change timing, the process returns to step S304.

  Here, since the four-digit input has already been completed, the password is stored as “1 (external character symbol) 34”, and the password input process is terminated (screen (vi)).

  Next, the password analysis processing in step S202 of FIG. 2 is executed, and the passwords do not match. Therefore, the CPU 101 causes the display device 109 to display “Password is wrong” for a certain period of time and prompts the user to input the password again. A predetermined error handling process (step S204) such as displaying (i) is performed.

  If the passwords do not match, the CPU 101 causes the display device 109 to display “password is incorrect” for a certain period of time, and also causes the sound device 110 to generate a warning sound or is stored in the storage medium 103. Existing data may be deleted, or the power may be turned off.

  As described above in detail, according to the present embodiment, the timing for changing the input mode during password input is set (step S301), and when the set timing is reached, the input mode is changed. (YES in step S308), the user is notified that the input mode has been changed (step S309), and data input by the user in the input mode after the change (input mode return instruction data; touch panel by the user) On the basis of the contact), it is determined whether or not the input mode after the change returns to the input mode before the change (step S311). As described above, the input mode is changed during the password input, and it is possible to return to the input mode before the change by a simple operation. Therefore, it is possible to perform authentication while ensuring security by a simple operation.

  In addition, since the timing (X) for changing the input mode is automatically calculated and set based on the current date and time (FIG. 4), the user does not need a special prior operation such as data registration. Authentication can be performed while ensuring security with a simple operation.

  Furthermore, when the data input by the user does not match the data for returning to the input mode (input mode return instruction data; touching the touch panel by the user), the data input by the user is input device Since it is converted into predetermined data (for example, an external character symbol) that cannot be input at 106 (step S313), high security can be ensured.

  The timing (X) for changing the input mode is a timing for inputting any one of the plurality of codes constituting the password (that is, there is a timing for inputting the first digit of the password). , There is also the timing of the second, third ... digit of the password). Thus, since the timing (X) for changing the input mode is not the same every time, but can be changed according to the password, high security can be ensured.

  Another object of the present invention is to supply a storage medium storing software program codes for realizing the functions of the above-described embodiments to a system or apparatus, and the computer of the system or apparatus (or CPU, MPU, or the like). Is also achieved by reading and executing the program code stored in the storage medium.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the program code and the storage medium storing the program code constitute the present invention. .
