  The present invention relates to an authentication code generation method and an authentication code authentication method used for a portable information terminal and an electronic device, and more particularly to an authentication code generation method and an authentication code authentication that are applied to a portable information terminal that does not have a keyboard to suppress unauthorized use. Regarding the method.

  In various electronic devices such as mobile phone terminals and information processing terminals, passwords (authentication codes) are used to restrict users of the electronic devices and to limit the functions that can be used for each user. Things are being done.

  For example, by registering a user's password in an electronic device and always requesting the password to be used at the time of use, the electronic device can be used only by those who know the password. Yes. In addition, a predetermined function is requested to input a password at the start of the function so that only the person who knows the password can use the function.

  In this way, by performing authentication processing using a password, the electronic device is illegally used and the owner is damaged, or personal information stored in the mobile phone terminal is leaked to others. It is designed to deter abuse.

  As described above, many password mechanisms are used for authentication by inputting predetermined characters and numbers. On the other hand, there are increasing opportunities for authentication on smartphones and mobile phones that do not have a keyboard, and input means are provided for each, but there are cases where the operation is complicated. For example, in the case of a combination of alphanumeric characters, it is necessary to switch the input from English to numeric mode.

  Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In the embodiments described below, a case where the present invention is applied to a mobile phone terminal will be described as an example. In addition, about the technique which comprises a mobile telephone terminal, since a well-known technique is applicable unless it limits in particular, detailed description is abbreviate | omitted.

(First embodiment)
FIG. 1 is an external view of a mobile phone terminal according to the first embodiment of the present invention.

  The cellular phone terminal 1 includes a transmission / reception antenna 2, a key operation unit 3, a display unit 4, a speaker 5, and a microphone 6.

  The transmission / reception antenna 2 transmits / receives radio data to / from the mobile communication base station. A known technique can be applied to the transmission / reception method.

  As shown in FIG. 1, the key operation unit 3 includes, for example, a so-called cross key that can be pressed up, down, left, and right, several function keys, numeric keys 0 to 9, * key, # key, and the like. So-called numeric keys (numeric keys, character keys, symbol keys) and the like. Function keys and numeric keys can be pressed. Through these operation keys, the mobile phone terminal of the present embodiment can accept various instruction inputs from the user (user).

  Of the operation keys provided in the key operation unit 3, detection of pressing of the cross key, function key, and numeric keypad does not merely accept an on / off operation (pressing operation) from the user. In the mobile phone terminal of the present embodiment, each operation key can receive a pressing operation from a user and can detect a pressing time at the time of the pressing operation.

  In addition to performing a dial operation during a call when pressed by the user, in particular, in the present embodiment, an authentication code (registration authentication code and authentication code) is input.

  The display unit 4 is an LCD (Liquid Crystal Display) or EL (Electroluminescence) for displaying various image information such as characters, figures, symbols, still images, and moving images, but is not limited thereto. Any known technique can be used as long as it can display image information. In the present embodiment, the display unit 4 is a TFT color liquid crystal display with a relatively large display screen (Thin Film Tantasist Color Liquid Crystal Display).

  The mobile phone terminal of this embodiment is connectable to the Internet, and displays image information such as so-called Web pages and e-mails provided on the Internet on the display unit 4.

  Further, the display unit 4 may display an authentication code input screen for inputting a registration authentication code or an authentication code for authentication (hereinafter also referred to as a password but indicating the same). Further, a bar graph or the like that sensuously indicates the time during which the operation key 3 is pressed when inputting the authentication code may be displayed for each key.

  The speaker 5 generates a ring tone or a warning sound for notifying an incoming call, or listens to a sound.

  The microphone 6 outputs sound during a call.

  Further, the mobile phone terminal of the present embodiment is provided with a vibration unit (vibrator) 12 (not shown) for notifying incoming calls. Vibrator 12 vibrates at the time of an incoming call, and notifies the incoming call happily.

  FIG. 2 is an internal configuration diagram of the mobile phone terminal according to the first embodiment of the present invention.

  The mobile phone terminal 1 includes an antenna 2, a key operation unit 3, a display unit 4, a speaker 5, a microphone 6, a transmission / reception unit 10, a control unit 11, a vibration unit (vibrator) 12, a measurement unit 13, and a storage unit 14. Configured.

  Since the antenna 2, the key operation unit 3, the display unit 4, the speaker 5, and the microphone 6 are the same as described above, the details are omitted.

  The transmission / reception unit 10 performs transmission / reception processing of wireless data via the antenna 2 and performs modulation / demodulation of the wireless data.

  The control unit 11 includes a CPU (Central Processing Unit) 11a that controls the entire mobile phone terminal 1 of the present embodiment, a ROM (Read Only Memory) 11b that stores a control program for setting an authentication code, and a RAM 11c. Is provided.

  For example, the ROM 11b stores necessary data such as a control program executed by the CPU 11a and a display font.

  The RAM 11c is mainly used as a work area, and stores data in the middle of calculation as needed while the CPU 11a is executing a control program, and temporarily stores data exchanged between the control unit 11 and each unit. Used when

  For example, the control unit 11 generates, as a registration authentication code, a combination of a combination with a relative ratio of pressing times of each operation key corresponding to each operation key (number, character, symbol, etc.) of the key operation unit 3 And set it as an authentication code. Then, the control unit 11 determines whether or not the authentication code input by the key operation unit 3 matches the registration authentication code stored in the storage unit 14, and releases the operation lock when they match. Then, a predetermined operation corresponding to the function of the mobile phone terminal is performed.

  The vibration unit (vibrator) 12 vibrates at the time of an incoming call, so that the incoming call is notified in a tactile manner.

  When the control unit 11 detects that the operation key of the key operation unit 3 is pressed, the measurement unit 13 starts measuring the pressed time, and when the pressing is stopped, the measurement ends. The pressed time is calculated. A combination of a combination of a number, a character, a symbol, and the like corresponding to the pressed operation key and a relative time of the pressed time of the operated key is set as the above-described registration authentication code and authentication code. .

  The measuring unit 13 has a so-called calendar function that provides the current time, current date, current day, and the like, and various clocks required by the mobile phone terminal by using, for example, its own crystal oscillator. Signals and timing signals can be formed.

  Then, based on the reference clock signal provided by the measurement unit 13, the operation key for inputting the password is pressed based on the timing when the operation key for inputting the first password is pressed (at the start of password input). The operating time is detected, and the relative time information is used as information constituting the password based on the relative ratio of the pressing time of each operation key.

  By calculating the relative ratio of the pressing time of each operation key in this way, for example, if the password is composed of about 4 digits, for example, numerical information assigned to the operation key that is simply pressed. Instead of constructing a password only, the pressing time for each operation key pressed to input the numbers that make up the password and the relative ratio of the pressing times are also used as components of the password. Therefore, the confidentiality of the password can be increased and the password is prevented from being easily broken.

  In addition, since the human time sensation is likely to change from operator to operator, even from the same operator, even from the date, it is not always possible to press the button at the correct time, so the authentication success rate may be lowered It is possible to solve the problem.

  The storage unit 14 is configured by, for example, a flash ROM (Flash Read Only Memory) or a RAM (Random ACCESS Memory), and stores in advance an authentication code (registration authentication code) input by the key operation unit 3.

  Although not shown, the control unit 11 includes an external interface (hereinafter abbreviated as an external I / F) and an input / output terminal, through which, for example, an external device such as a personal computer, Data can be sent and received.

  Although not shown, the mobile phone terminal includes a removable external memory slot, reads data from the attached external memory and supplies the data to the control unit 11, and sends data from the control unit 11 to the external memory. It has a function as a so-called reader / writer for recording. Here, the external memory is an SD memory card (registered trademark), for example, and is a removable storage medium using a semiconductor memory.

<Authentication code setting method>
FIG. 3 is a diagram for explaining an authentication code setting method used for the mobile phone terminal according to the first embodiment of the present invention.

  With reference to FIG. 3, the detail of the setting method of the authentication code used for this mobile telephone terminal is demonstrated.

  When the control unit 11 detects that the operation key of the key operation unit 3 is pressed, the measurement unit 13 starts measuring the time during which the operation key is pressed, and ends the measurement when the pressing is stopped. Thus, the pressed time is calculated.

  Then, the times when the operation keys are pressed are sequentially added by the number of authentication codes (four in this example), and the relative ratios where the operation keys are pressed are calculated. The number of authentication codes is not limited to four and can be set to an arbitrary number. A combination of at least two or more operation keys is suitable.

  In FIG. 3, “key A” is pressed for 1 second, “key B” is pressed for 3 seconds, “key C” is pressed for 4 seconds, and “key D” is pressed for 2 seconds. Since the total time for which the four keys are pressed is 10 seconds, the relative ratio of the time for which each key is pressed is A: B: C: D = 1: 3: 4: 2.

  In the present embodiment, only the time during which the operation key of one authentication code is pressed is measured, and the time until the operation key of the next authentication code is pressed is not measured. By not counting (measuring) the time when the operation keys are released in this way, depending on the user, the problem is that the search speed for the operation keys is different, and the operation key arrangement varies depending on the terminal. Can solve the problem of different search speed. As a result, even a user who is unfamiliar with the operation can input a correct authentication code.

  Then, a combination of a combination of a number, a character, a symbol, or the like corresponding to the pressed operation key and a relative ratio of the pressed time of the operation key is set as the registration authentication code and the authentication code described above. Is done. Note that the order in which the operation keys are pressed is also applied as the configuration of the authentication code as in the conventional password. In this case, (1) code 15 shown in FIG. 3 is formed (A * B *** C ****** D *).

  In this embodiment, since the relative ratio of the pressing time of the operation key is used, for example, as shown in parentheses in FIG. 3, “key A” is 1.5 seconds, “key B” is 4.5 seconds, “ Even when the key “C” is pressed for 6 seconds and the “key D” is pressed for 3 seconds, the relative ratio of the time each key is pressed is A: B: C: D = 1: 3: 4: 2. Since the relative ratio of authentication codes A: B: C: D is established, authentication is performed.

  In this way, there is no device such as a counter that displays an accurate time to correct the time sensation. For example, even if the time sensation of “1 second” changes depending on the date and time, it is authenticated if the relative ratio is established. Therefore, a counter or the like that displays an accurate time for correcting the time sensation is not required on the authentication screen.

  In order to make it easier for the user to understand the relative time, a display such as a bar graph, for example, indicating how long the operation key 3 is pressed on the display unit 4 is displayed for each operation key. Also good. As a display method at this time, there is a display method such as (2) code: group 16 as shown in FIG. 3. However, the display method is not limited to this, and the method can be visually understood by the user. If it is good.

  If the relative ratio of the operation key pressing time is used, the following usage is possible. For example, it is assumed that the registration authentication code is set by pressing “key A” for 1 second, “key B” for 3 seconds, “key C” for 4 seconds, and “key D” for 2 seconds. When the authentication code for authentication must be entered in front of the public, the first time “Key A” is 1.5 seconds, “Key B” is 4.5 seconds, “Key C” is 6 seconds, “Key D” "" Is pressed for 3 seconds and authenticated. Next, for the second time, “key A” is pressed for 1 second, “key B” is pressed for 3 seconds, “key C” is pressed for 4 seconds, and “key D” is pressed for 2 seconds for authentication. And the third time, if “Key A” is pressed for 2 seconds, “Key B” is 6 seconds, “Key C” is 8 seconds, and “Key D” is pressed for 4 seconds, the operation is pressed. The key and the order are seen by others, but since the time of pressing is different in all of the first to third times, the possibility that the authentication code is known to others will be low.

  As described above, even for an electronic device with few operation keys such as a mobile phone terminal, a combination of the operation key and the relative ratio of the pressing time is coded as the registration authentication code and the authentication code. Therefore, more combinations are possible than combinations of operation keys (numbers, characters, symbols, etc.), and the security of the electronic device is improved. A combination of the operation key and the relative time when each operation key is pressed may be set as the registration authentication code and the authentication code.

  In this embodiment, the order in which the operation keys are pressed as in the case of the conventional password is described as an example of the configuration of the authentication code. However, the present invention is not limited to this, and the order in which the operation keys are pressed is related. Alternatively, authentication may be performed if the type of the pressed operation key and the relative ratio of the pressed time of each operation key match as a group. In this case, the number of combinations of authentication codes is smaller than the order in which the operation keys described above are pressed is applied as a configuration of authentication codes. In this case, (2) code: group 16 shown in FIG.

<Authorization code registration flow>
FIG. 4 is a diagram for explaining the flow of an authentication code setting process used for the mobile phone terminal according to the first embodiment of the present invention.

  First, processing at the time of registration of an authentication code will be described. In the mobile phone terminal according to the present embodiment, the process is executed in the control unit 11 when the user performs a predetermined operation to shift the mobile phone terminal to the authentication code registration mode.

  When the user shifts to the authentication code registration mode, the control unit 11 of the mobile phone terminal waits for an authentication code registration setting start input from the user (step S1). If it is determined that an authentication code setting start input has been made (step S1, YES), the control unit 11 accepts an input of, for example, a 4-digit authentication code through the key operation unit 3 (step S2). If there is no authentication code setting start input, the determination is repeated (step S1, NO).

  Then, as described above, the control unit 11 detects and measures the pressing time of each operation key related to the authentication code input based on the sampling signal from the measuring unit 13, and stores the time (step S3). . Next, it is determined whether or not an input of a predetermined number of predetermined authentication codes has been accepted (step S4).

  If the input of the predetermined number of authentication codes has not been accepted (step S4, NO), the processing from step S2 is repeated.

  When the input of the predetermined number of authentication codes is received (step S4, YES), the control unit 11 calculates the relative ratio of the pressing time of each operation key (step S5). And the control part 11 memorize | stores what coded the combination of the input information of four digits, for example, and the relative ratio of pressing time (step S6).

  The stored code is registered as an authentication code in the corresponding area of the flash memory 11b, for example, in the order in which the operator presses each operation key (step S7), and the authentication code registration process is terminated.

  In the authentication code registration process, the relative ratio of the pressing time of each operation key is described as being included in the authentication code, but the present invention is not limited to this. For example, when the authentication code is input multiple times and the relative ratio of the pressing times is within a predetermined range in each time, the standardized average value is encoded. Various processes such as use can be performed.

<Authentication code authentication flow>
FIG. 5 is a diagram for explaining the flow of the authentication code authentication process used for the mobile phone terminal according to the first embodiment of the present invention.

  First, processing at the time of authentication using an authentication code will be described. In the mobile phone terminal of this embodiment, for example, when referring to the phone book data registered in the terminal or referring to an e-mail, it is confirmed whether or not the user is the user of the mobile phone terminal. For example, an input of a four-digit authentication code is requested, and a process for performing an authentication process using the authentication code is executed.

  First, the control unit 11 of the mobile phone terminal enters a waiting state for input of verification code verification start from the user (step S10). When it is determined that the verification code verification start input has been made (step S10, YES), the control unit 11 accepts an input of, for example, a 4-digit authentication code through the key operation unit 3 (step S11).

  Then, as described above, the control unit 11 detects the pressing time of each operation key related to the authentication code input based on the sampling signal from the measurement unit 13 in the same manner as the process of step S3 shown in FIG. And measure the time (step S12). Next, it is determined whether or not an input of a predetermined number of predetermined authentication codes has been accepted (step S13).

  When the input of the predetermined number of authentication codes is not accepted (step S13, NO), the processing from step S11 is repeated.

  When the input of the predetermined number of authentication codes is received (step S13, YES), the control unit 11 calculates the relative ratio of the pressing time of each operation key (step S14). And the control part 11 memorize | stores what coded the combination of the input information of four-digit numbers, and the relative ratio of pressing time, for example (step S15).

  Next, the control unit 11 reads out the registration authentication code registered in the flash memory 11b, for example, using the codes stored in the order of pressing the operation keys as an authentication code, and collates with the registration information (step S16). ).

  The collation in step S16 matches (matches) if the relative ratio of the input authentication code pressing time is within a predetermined range in relation to the registration authentication code as described above. It is considered to be.

  And the control part 11 judges whether the collation result in step S16 corresponds with the registration authentication code and the input authentication code which started reception at step S11 (step S17).

  If it matches the registered authentication code (step S17, YES), it is authenticated, so access permission is issued, and for example, a process intended by the user such as reference to phone book data or e-mail is executed (step). S18).

  In the determination process of step S17, when the registration authentication code does not match (NO in step S17), for example, an access disapproval such as displaying a message notifying that the access cannot be permitted because the authentication code is not accurate. Processing is executed (step S19).

  Then, the control unit 11 receives a confirmation input as to whether or not to re-enter the authentication code from the user, and determines whether or not to re-enter the authentication code (step S20). When it is determined that the re-input of the authentication code is instructed (step S20, YES), the control unit 11 repeats the processing from step S11, receives the re-input of the authentication code, and collates with the registered password. Like that.

  If it is determined that the re-input of the authentication code has not been instructed (step S20, NO), the process ends. In this case, since the match between the input authentication code and the registration authentication code has not been confirmed, the target processing such as reference to telephone book data or electronic mail cannot be executed.

<Operational effects of this embodiment>
As described above, by applying the authentication code generation method and the authentication code authentication method of the present invention to authentication processing, many combinations of authentication codes are possible even in an electronic device with few operation keys such as a mobile phone terminal. The security of electronic equipment will be improved.
Also, by not counting (measuring) the time for which the operation keys are released, some users may find the operation keys to be used more or less accustomed because the speed of searching for the operation keys is different or the operation keys are arranged differently depending on the terminal. The problem that the speed of searching is different can be solved, and even a user unfamiliar with the operation can input a correct authentication code.

As a display method at this time, there is a display method such as (2) code: group 22 as shown in FIG. 7, but the display method is not limited to this and is a method that can be visually understood by the user. I just need it.

  The portable information terminal according to the present embodiment is provided with a vibration unit (vibrator) 12 (not shown) for notifying incoming calls. Vibrator 12 vibrates at the time of an incoming call, and notifies the incoming call happily.

  Note that the internal configuration of the portable information terminal 20 of this embodiment is the same as that of the first embodiment and a known portable information terminal (for example, a PDA), and thus detailed description thereof is omitted.

<Authentication code setting method>
FIG. 7 is a view for explaining an authentication code setting method used for the portable information terminal according to the second embodiment of the present invention.

  With reference to FIG.7 and FIG.6, the detail of the setting method of the authentication code used for this portable information terminal is demonstrated.

  When the control unit 11 detects that the cross operation key of the key operation unit 3 has been pressed, the measurement unit 13 starts measuring the time during which the operation key is pressed, and the measurement is performed when the pressing is stopped. At the end, the pressed time is calculated.

  Then, the times when the operation keys are pressed are sequentially added by the number of authentication codes (four in this example, top, bottom, left, and right), and the relative ratios where the operation keys are pressed are calculated. The number of authentication codes is not limited to four and can be set to an arbitrary number. A combination of at least two or more operation keys is suitable.

  In FIG. 7, “Cross key up” is pressed for 1 second, “Cross key left” is pressed for 3 seconds, “Cross key right” is pressed for 4 seconds, and “Cross key down” is pressed for 2 seconds. Since the sum of the four key pressing times is 10 seconds, the relative ratio of the time when each key is pressed is up: left: right: down = 1: 3: 4: 2.

  In the present embodiment, only the time during which the operation key of one authentication code is pressed is measured, and the time until the operation key of the next authentication code is pressed is not measured. By not counting (measuring) the time when the operation keys are released in this way, depending on the user, the problem is that the search speed for the operation keys is different, and the operation key arrangement varies depending on the terminal. Can solve the problem of different search speed. As a result, even a user who is unfamiliar with the operation can input a correct authentication code.

  Then, a combination of the combination with the relative ratio of the pressing time of the operation key corresponding to the pressed cross operation key is set as the above-described registration authentication code and authentication authentication code. Note that the order in which the operation keys are pressed is also applied as the configuration of the authentication code as in the conventional password. In this case, a line like (1) code 21 shown in FIG. 7 is formed (upper * left *** right *** lower *). It becomes.

  In this embodiment, since the relative ratio of the pressing time of the operation key is used, for example, as shown in parentheses in FIG. 7, “cross key up” is 1.5 seconds and “cross key left” is 4.5 seconds. Even when “Cross Key Right” is pressed for 6 seconds and “Cross Key Down” is pressed for 3 seconds, the relative ratio of the time that each key is pressed is up: left: right: down = 1: 3: 4. : 2, and the authentication code is authenticated because the relative ratio of upper: left: right: lower is established.

  In this way, there is no device such as a counter that displays an accurate time to correct the time sensation. For example, even if the time sensation of “1 second” changes depending on the date and time, it is authenticated if the relative ratio is established. Therefore, a counter or the like that displays an accurate time for correcting the time sensation is not required on the authentication screen.

  In order to make it easier for the user to understand the relative time, a display such as a bar graph, for example, indicating how long the operation key 3 is pressed on the display unit 4 is displayed for each operation key. Also good. As a display method at this time, there is a display method such as (2) code: group 22 as shown in FIG. 7, but the display method is not limited to this, and a method that can be visually understood by the user If it is good.

  If the relative ratio of the operation key pressing time is used, the following usage is possible. For example, it is assumed that the registration authentication code is set by pressing “Cross Key Up” for 1 second, “Cross Key Left” for 3 seconds, “Cross Key Right” for 4 seconds, and “Cross Key Down” for 2 seconds. . When the authentication code for authentication must be entered in front of the public, the first time, “Cross key up” is 1.5 seconds, “Cross key left” is 4.5 seconds, “Cross key right” is 6 seconds, "Cross key down" is pressed for 3 seconds for authentication. Next, for the second time, “Cross key up” is pressed for 1 second, “Cross key left” is pressed for 3 seconds, “Cross key right” is pressed for 4 seconds, and “Cross key down” is pressed for 2 seconds for authentication. Then, for the third time, “Cross Key Up” is pressed for 2 seconds, “Cross Key Left” is 6 seconds, “Cross Key Right” is 8 seconds, “Cross Key Down” is 4 seconds, and authentication is performed. The operation keys and the order to be pressed will be seen by others, but the time of pressing will be different in the first to third times, so the possibility that the authentication code will be known to others is low. Become.

  In this embodiment, the order in which the operation keys are pressed as in the case of the conventional password is described as an example of the configuration of the authentication code. However, the present invention is not limited to this, and the order in which the operation keys are pressed is related. Alternatively, authentication may be performed if the type of the pressed operation key and the relative ratio of the pressed time of each operation key match as a group. In this case, the number of combinations of authentication codes is smaller than the order in which the operation keys described above are pressed is applied as a configuration of authentication codes. In this case, (2) code: group 22 shown in FIG.

  As described above, even for an electronic device having only a cross operation key such as a portable information terminal, a combination of an operation key and a relative ratio of pressing times is encoded as a registration authentication code and an authentication code. Therefore, many combinations of cross operation keys are possible, and the security of the electronic device is improved. For example, digital devices such as digital cameras, portable game devices, and televisions, air conditioners, audio, home game consoles, etc. that are operated with a remote controller as home appliances, and other authentication codes (passwords) in the future You may apply to what needs. A combination of the operation key and the relative time when each operation key is pressed may be set as the registration authentication code and the authentication code.

  Note that the authentication code registration process, authentication code setting process, authentication code authentication process, and authentication code authentication process in the present embodiment are the same as those described in the first embodiment, and thus are detailed. Description is omitted.

<Operational effects of this embodiment>
As described above, by applying the authentication code generation method and the authentication code authentication method of the present invention to the authentication process, many combinations of authentication codes are possible even in an electronic device having only a cross operation key such as a portable information terminal. As a result, the security of the electronic device is improved.
Also, by not counting (measuring) the time for which the operation keys are released, some users may find the operation keys to be used more or less accustomed because the speed of searching for the operation keys is different or the operation keys are arranged differently depending on the terminal. The problem that the speed of searching is different can be solved, and even a user unfamiliar with the operation can input a correct authentication code.
