The operation unit 11 includes the input unit 13 and the touch sensor 14 as described above.
The input unit 13 outputs, to the CPU 95, an input signal that is input when the function setting operation key 131, the input operation key 132, and the determination operation key 133 constituting the input unit 13 are pressed.
The touch sensor 14 is connected to a later-described CPU 95 (a later-described operation pattern detection unit 951) via a signal line (not shown), and when a finger or the like as a conductor contacts and / or approaches the touch sensor 14. The resulting voltage change is output to the CPU 95.

The main antenna 90 constitutes a wireless communication unit. The main antenna 90 communicates with an external device in a predetermined use frequency band (for example, 800 MHz). Examples of communication performed by the main antenna 90 include voice call and transmission / reception of electronic mail.
In the present embodiment, the predetermined use frequency band is 800 MHz, but another different frequency band may be used. The main antenna 90 may have a so-called dual-band configuration that can support not only a predetermined use frequency band but also other use frequency bands (for example, 2 GHz).

  The RF circuit unit 91 demodulates the signal received by the main antenna 90, supplies the processed signal to the CPU 95, modulates the signal supplied from the CPU 95, and performs an external device (base) via the main antenna 90. Station).

The display control unit 92 performs predetermined image processing on the input image data and outputs the image processed image data to the driver IC 34 under the control of the CPU 95.
The driver IC 34 stores the image data input from the display control unit 92 in the frame memory, and outputs the image data stored in the frame memory to the display unit 32 at a predetermined timing.
The display unit 32 displays predetermined characters and images based on the data input from the driver IC 34.

The audio processing unit 93 performs predetermined audio processing on the signal supplied from the RF circuit unit 91 according to the control of the CPU 95 and outputs the audio-processed signal to the receiver 33. In addition, the sound processing unit 93 performs predetermined processing on the signal input from the microphone 12 and outputs the processed signal to the RF circuit unit 91 according to the control of the CPU 95. The RF circuit unit 91 performs predetermined processing on the signal input from the audio processing unit 93 and outputs the processed signal to the main antenna 90.
The receiver 33 emits sound (outputs) to the outside based on the signal supplied from the sound processing unit 93.

  The timer 98 measures time corresponding to a predetermined operation on the operation unit 11. Specifically, the timer 98 performs the following operation after the pressing time when a predetermined key constituting the input unit 13 is pressed or the pressing of one key when a plurality of keys are sequentially pressed is released. The time (interval) until the key is pressed is measured. Information on the time measured by the timer 98 is output to the CPU 95 (an operation pattern detection unit 951 described later).

  The memory 94 stores predetermined data. Specifically, the memory 94 stores a release password, a release operation pattern, and the like, which will be described later, in addition to various function programs and address information used during communication.

  The CPU 95 controls the entire mobile phone 1. The CPU 95 performs predetermined control on the RF circuit unit 91, the display control unit 92, the audio processing unit 93, and the like. A specific configuration of the CPU 95 will be described later.

The power supply unit 96 includes a battery. The battery is a lithium ion battery having a predetermined capacity.
The control IC 97 converts the power supply voltage supplied from the power supply unit 96 into a predetermined power supply voltage, and supplies the converted power supply voltage to each unit (for example, the CPU 95) of the mobile phone 1.

  Next, a password authentication function in the mobile phone 1 will be described with reference to FIG. FIG. 4 is a functional block diagram showing a configuration for the mobile phone 1 to exhibit the password authentication function.

  As shown in FIG. 4, the mobile phone 1 includes an operation unit 11 having an input unit 13 and a touch sensor 14, a timer 98, a memory 94, and a CPU 95 as a configuration for exhibiting a password authentication function. .

The memory 94 includes a password storage unit 941, an operation pattern storage unit 942, and a cumulative storage unit 943 as a pattern storage unit.
The password storage unit 941 stores a release password for allowing the CPU 95 (execution control unit 954 described later) to execute a predetermined function of the mobile phone 1. In the password storage unit 941, for example, a 4-digit number is stored as a release password. The release password may be changeable by the user by a predetermined operation.

  The operation pattern storage unit 942 stores a release operation pattern for allowing the CPU 95 (execution control unit 954 described later) to execute a predetermined function of the mobile phone 1. For example, when inputting a password, the operation pattern storage unit 942 stores a locus of movement of a finger touching the touch sensor 14.

  The accumulation storage unit 943 accumulates and stores operation patterns detected by the CPU 95 (operation pattern detection unit 951 described later). In other words, the cumulative storage unit 943 stores a history of the movement of the finger touching the touch sensor 14 in association with the password input operation.

  The CPU 95 includes an operation pattern detection unit 951, a password determination unit 952, an operation pattern determination unit 953, an execution control unit 954, and a pattern creation unit 955.

  The operation pattern detection unit 951 detects an operation pattern that is a pattern related to a password input operation on the input unit 13. Specifically, the operation pattern detection unit 951 detects XY coordinate data at a position where the voltage in the touch sensor 14 has changed based on a change in voltage output from the touch sensor 14, and also obtains time information from the timer 98. get. And the operation pattern detection part 951 detects an operation pattern based on XY coordinate data and time information. That is, the operation pattern detection unit 951 detects the locus of movement of the finger that touches the touch sensor 14 when inputting a password.

  The password determination unit 952 determines whether or not the password input to the input unit 13 matches the release password stored in the password storage unit 941.

  The operation pattern determination unit 953 determines whether or not the operation pattern detected by the operation pattern detection unit 951 matches the release operation pattern stored in the operation pattern storage unit 942. Here, the operation pattern determination unit 953 determines that the operation pattern detected by the operation pattern detection unit 951 and the cancel operation pattern stored in the operation pattern storage unit 942 are completely the same, and that both patterns are approximate. If it does, it is determined as “match”.

  The execution control unit 954 controls execution of a predetermined function of the mobile phone 1. Specifically, the execution control unit 954 determines that the password input by the input unit 13 matches the unlock password by the password determination unit 952, and detects the operation pattern detection unit 951 by the operation pattern determination unit 953. When it is determined that the performed operation pattern matches the cancel operation pattern, execution of a predetermined function is permitted.

  The pattern creation unit 955 creates a release operation pattern based on the operation pattern accumulated in the accumulation storage unit 943. The pattern creation unit 955 updates the release operation pattern stored in the operation pattern storage unit 942 in the initial password setting every time the password is input a predetermined number of times. That is, the pattern creation unit 955 creates a new release operation pattern based on the history of operation patterns accumulated and stored in the accumulation storage unit 943, and stores the newly created release operation pattern in the operation pattern storage unit 942. .

Here, specific examples of the (cancel) password and the (cancel) operation pattern in the mobile phone 1 of the first embodiment will be described with reference to FIGS.
FIG. 5 is a diagram for explaining a release operation pattern (finger movement). FIG. 6 is a diagram for explaining the operation of the mobile phone 1 when the operation pattern detected by the operation pattern detection unit 951 matches the release operation pattern. FIG. 7 is a diagram illustrating the operation of the mobile phone 1 when the operation pattern detected by the operation pattern detection unit 951 does not match the release operation pattern.

As shown in FIGS. 5 to 7, the release password is set to “5297”. Further, as shown in FIGS. 5 and 6, the release operation pattern is such that the route is in the order of arrows A, B, and C, and the touch by the touch sensor 14 in the arrows A and B (trace the operation surface with a finger). ) Is detected, and in the arrow C, contact by the touch sensor 14 is not detected.
Here, the arrow A indicates the movement from “5” to “2”, the arrow B indicates the movement from “2” to “9”, and the arrow C indicates “9” to “7”. Indicates movement.

  When the release password and the release operation pattern are set in this way, the execution control unit 954 determines that the input password matches the release password “5297”, and the detected operation pattern is the release operation pattern. When it is determined that they coincide with (arrows A, B, C), execution of a predetermined function (for example, a mail function) is permitted.

  Specifically, as shown in FIG. 6, keys corresponding to “5”, “2”, “9”, and “7” are pressed, and “5297” is input as a password by the input unit 13, and “5” When moving from the key corresponding to "2" to the key corresponding to "2" and from the key corresponding to "2" to the key corresponding to "9", the finger moves so that the operation surface is traced When the key corresponding to “9” is moved to the key corresponding to “7” and the finger is moved away from the operation surface, the execution control unit 954 sends a mail as a predetermined function. Allow execution of the function. As a result, the so-called security state is canceled and the mail function can be used.

  Even if the input password matches the release password, the execution control unit 954 does not release the security state and does not release the security state if the detected operation pattern does not match the release operation pattern. ) Is not allowed.

  For example, when touch is not detected by the touch sensor 14 at the arrow A or arrow B in FIG. 6 (when the finger is not moved so as to trace the operation surface), or when touch is detected by the touch sensor 14 at the arrow C (operation When the finger is moved so as to trace the surface), the execution control unit 954 does not permit execution of the predetermined function.

Further, the execution control unit 954 naturally does not permit execution of the predetermined function even when the path between the release operation pattern and the detected operation pattern is different.
Specifically, as shown in FIG. 7, “2” instead of “2” → “9” directly in the path for moving the finger from the key corresponding to “2” to the key corresponding to “9”. → “3” → When the finger is moved so as to pass through the keys (surfaces) corresponding to “9” and “3”, the execution control unit 954 does not permit execution of the predetermined function.

  Here, the operation pattern shown in FIG. 7 can also be registered as a release operation pattern. When the operation pattern shown in FIG. 7 is registered as a release pattern, a special element (operation) that passes through “3”, which is an element that does not exist in the password “5297”, is added, so that security is improved. .

Next, the operation of the mobile phone 1 when the password authentication function is used will be described with reference to FIG.
FIG. 8 is a flowchart for explaining the password authentication function in the mobile phone 1.

  The mobile phone 1 is set so that the password authentication function is activated by a predetermined operation. For example, when a predetermined input operation is performed on the input unit 13 to activate the mail function, a screen requesting password input is displayed on the display unit 32 (see FIG. 5), and the password authentication process shown in FIG. 8 is executed. The

  First, the CPU 95 starts measuring time by the timer 98 (ST1). Next, the password determination unit 952 determines whether or not there is a first key input by the input operation key 132 (ST2). If there is a first key input, the process proceeds to ST3, and if there is no first key input, the process proceeds to ST2.

  In ST3, the CPU 95 stores a number corresponding to the key input in the input unit 13 in a predetermined storage area of the memory 94. Furthermore, the operation pattern detection unit 951 performs processing for recognizing an operation pattern described later (ST4). Then, the password determination unit 952 determines whether or not the password input is completed (ST5). If the password input is completed, the process proceeds to ST6, and if the password input is not completed, the process proceeds to ST3. Move processing. If the password is, for example, a four-digit number, for example, when a four-digit number is input and the determination operation key 133 is pressed, the process proceeds to ST6 assuming that the password input is completed.

In ST6, the CPU 95 ends the time measurement by the timer 98. Next, the password determination unit 952 performs a process of determining whether or not the input password matches the release password stored in the password storage unit 941 (ST7). If the password determination unit 952 determines that the input password matches the release password, the process proceeds to ST8. If the password determination unit 952 determines that the input password does not match the unlock password, the fact that password authentication has failed is displayed on the display unit 32 (see FIG. 7), and the security state is continued (ST11). ).
In ST8, the operation pattern determination unit 953 compares the operation pattern detected by the operation pattern detection unit 951 in ST4 with the release operation pattern stored in the operation pattern storage unit 942, and determines whether or not they match. If the operation pattern determination unit 953 determines that the detected operation pattern matches the release operation pattern (YES in ST9), the execution control unit 954 permits activation (execution) of the mail function (FIG. 6). See ST10). When the operation pattern determination unit 953 determines that the detected operation pattern does not match the release pattern (NO in ST9), the fact that password authentication has failed is displayed on the display unit 32 (see FIG. 7). The security state is continued (ST11).
It should be noted that the display indicating that the password authentication has failed may be displayed so as to indicate whether the password input does not match or the operation pattern does not match (see FIG. 7).

FIG. 9 is a flowchart of the operation pattern recognition process of FIG.
First, when the operation pattern detection unit 951 detects an input to the touch sensor 14 (YES in ST21), the operation pattern detection unit 951 stores the XY coordinate information as the operation position of the touch sensor 14 in the memory 94 in relation to the time measured by the timer 98. (ST22). Then, the operation pattern detection unit 951 detects operation pattern data based on the XY coordinate information stored in the memory 94 (ST23). With this operation pattern data, the movement of the user's finger, for example, the trajectory of the finger from the first input to the next input, the time when the finger pressed the touch sensor 14, and the like can be known. If no input to the touch sensor 14 is detected (NO in ST21), the process proceeds to ST23.

According to the mobile phone 1 of the first embodiment described above, the mobile phone 1 has the following effects.
(1) When it is determined that the password input by the input unit 13 matches the cancel password, and the operation pattern detected by the operation pattern detection unit 951 is determined to match the cancel operation pattern, the execution control unit 954A Permits execution of a predetermined function. As a result, parameters other than the password are verified in addition to the password in the personal authentication, so even if the password is leaked and password authentication is performed illegally, it is impossible to cancel the security state by just entering the password. It becomes. Therefore, the security function of the mobile phone 1 can be improved.

  (2) The mobile phone 1 includes a touch sensor 14 that detects, as an operation pattern, a trajectory of a finger that is touched or approached in association with a password input. Thereby, since personal authentication can be performed by the movement of the user's finger, further security enhancement can be achieved by a simple method.

  (3) The mobile phone 1 includes a pattern creation unit 955 that creates a release operation pattern based on the operation pattern accumulated and stored in the accumulation storage unit 943. Thereby, the mobile phone 1 can be provided with a so-called learning function of newly creating a release operation pattern in accordance with a user's password input history. Therefore, the personality when the user inputs the password is related to the personal authentication, and an effective release operation pattern can be set by a simple method.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.
FIG. 10 is a front view of the cellular phone 1 according to the second embodiment of the present invention in a state where the operation unit side body 2 and the display unit side body 3 are opened. FIG. 11 is a functional block diagram showing a configuration for the mobile phone 1 according to the second embodiment to exhibit the password authentication function. FIG. 12 is a flowchart of operation pattern recognition processing in the mobile phone 1 according to the second embodiment.
In addition, about the structure same as the structure in 1st Embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted. Hereinafter, the configuration different from the first embodiment will be mainly described.
Here, the present embodiment is the first embodiment in that the operation pattern is not the movement pattern of the user's finger when inputting the password, but the operation pattern is a temporal pattern when the password is input. Is different.

  As shown in FIGS. 10 and 11, the mobile phone 1 in the present embodiment is different from the mobile phone 1 in the first embodiment in that the touch sensor 14 is not provided.

As shown in FIG. 11, the functional block diagram in the present embodiment is the same as the functional block diagram in the first embodiment except that the touch sensor is not provided.
Only the configuration different from the first embodiment will be described below.

The operation pattern detection unit 951A detects a temporal pattern when a password is input by the input unit 13. The operation pattern detection unit 951 </ b> A detects a time pattern based on signals (press information) from the keys constituting the input unit 13 and time information from the timer 98.
Specifically, the time pattern is, for example, the pressing time of each key, the time (interval) from releasing the pressed state of a predetermined key until the other key is pressed, or a combination thereof. It is.

  The operation pattern determination unit 953A compares the release time pattern as the release operation pattern stored in the operation pattern storage unit 942A described later with the time pattern detected by the operation pattern detection unit 951A, and the detected time pattern is It is determined whether or not the release time pattern matches.

  The execution control unit 954A determines that the password input by the input unit 13 matches the unlock password by the password determination unit 952A and the time pattern detected by the operation pattern detection unit 951A by the operation pattern determination unit 953A. When it is determined that the release time pattern matches, execution of a predetermined function is permitted.

  The pattern creation unit 955A creates a release time pattern based on the time pattern accumulated and stored in the accumulation storage unit 943A described later.

  The operation pattern storage unit 942A stores the release time pattern. In the operation pattern storage unit 942A, the pressing time information for pressing a predetermined key in the input unit 13, the interval time information from when the pressing state of the predetermined key is released until another key is pressed, A release time pattern based on time information obtained by combining time information and interval time information is stored.

  The accumulation storage unit 943A accumulates and stores the time pattern detected by the operation pattern detection unit 951A. The cumulative storage unit 943A stores a history of time information (time pattern) in password input operations.

  Next, a password authentication function in the mobile phone 1 according to the second embodiment will be described. The operation of the password authentication function is the same as that of the first embodiment except that the operation pattern recognition process in ST4 and the release operation pattern in the operation pattern determination process in ST8 are different in the operation shown in FIG. For this reason, a different point from 1st Embodiment is demonstrated below.

  The release operation pattern in ST8 is set by the user's operation together with the 4-digit number that becomes the password when the password is initially set, and is stored in the operation pattern storage unit. The password may be preset at the time of factory shipment. In the second embodiment, the release operation pattern is registered based on the time of each key input operation when a password is input. Specifically, the time when each key is pressed when inputting a 4-digit password is longer or shorter than a predetermined time (for example, 1 second), and the input operation key 132 is released and the next input operation is performed. By individually setting whether the time until the key 132 is pressed is longer or shorter than a predetermined time (for example, 1 second), a series of input patterns from the start of the 4-digit password input to the end of the input is set.

Next, the operation pattern recognition process in 2nd Embodiment is demonstrated, referring FIG.
First, when the input operation key 132 is pressed (YES in ST31), the CPU 95A stores information on the time when the input operation key 132 is pressed in the memory 94 in relation to the time measured by the timer 98 (ST32). ). If the input operation key 132 has not been pressed, the process moves to ST33.
In ST33, when the operation pattern detection unit 951A detects that the input operation key 1 is released, in other words, when the user lifts the finger from the input operation key 132 (YES in ST33), the timer In association with the time count of 98, information on the time when the input operation key 132 is released is stored in the memory 94 (ST34). If the pressing of the input operation key 132 is not released, the process proceeds to ST35.
In ST35, the operation pattern detection unit 951A creates operation time data for each input operation key 132 and stores it in the memory 94. Based on this operation time data, whether the operation of each input operation key 132 in the 4-digit password input was a long press for a predetermined time or longer, a short press shorter than a predetermined time, or from the previous key input to the next key input. For example, it is possible to know whether or not the time is 1 second or more.

  Next, specific examples of the (cancel) password and the (cancel) operation pattern in the mobile phone 1 according to the second embodiment will be described. Here, as an example, a case where a password “5297” is input will be described. In order to cancel the security state in the second embodiment, the password “5297” must be correctly pressed, and the keying speed (time) parameter of the input operation key 132 must match. Specifically, for example, “time to press one key”, “time from releasing a finger to pressing the next key”, and the like. The operation pattern storage unit 942A stores in advance two parameters of 1 second or more and less than 1 second.

Temporarily, in the process of pressing the input operation key 132 “5297” for password input, “time to press one key”, “time from releasing one key to pressing the second other key” Is set in advance by the user as follows.
"5" pressing time: 1 second or longer Moving time from "5" to "2": 1 second or longer "2" pressing time: less than 1 second Moving time from "2" to "9": less than 1 second “9” pressing time: 1 second or longer Travel time from “9” to “7”: 1 second or longer “7” pressing time: less than 1 second In this case, the operation (time) pattern is “5” first. "5" is released after 1 second or more has passed, "2" is pushed after 1 second or more, "2" is released before 1 second has passed, and "9" before 1 second has passed. ”Is pressed,“ 9 ”is released after 1 second has elapsed,“ 7 ”is pressed after 1 second has elapsed, and“ 7 ”is released before 1 second has elapsed. For this reason, the security cannot be canceled unless the operation (time) pattern detected by the operation pattern detection unit 951A satisfies this condition. For example, even if the input operation of the password “5297” is accurately performed, if the pressing time of “2” is 1 second or longer, the security cannot be released. In this manner, not only the password but also the time for pressing the key is included in the parameters, so that a further security effect can be enhanced.

  In the second embodiment, as an example, the description has been given with a division method of 1 second or more and less than 1 second. However, if this time setting can be arbitrarily set by the user, and further setting, the security can be further improved. It leads to strengthening.

  According to the mobile phone 1 of the second embodiment, in addition to the effects (1) and (3) described above, the following effects can be obtained.

  (4) The mobile phone 1 detects the key input timing when the password is input as an operation pattern. As a result, personal authentication is performed based on the timing of key input, so that security can be further enhanced with a simple method.

The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the first embodiment, the capacitive touch sensor 14 is used, but the embodiment is not limited thereto. That is, other sensors may be used as long as they can detect a trajectory traced by a finger. For example, optical sensors may be arranged between the input operation keys 132 adjacent to each other.

The second embodiment may be combined with the first embodiment.
In the first embodiment, the touch sensor 14 is provided so as to cover the periphery of all the keys constituting the input unit 13. Therefore, a pattern of tracing an area other than the vicinity of the input operation key 132 may be set as the release operation pattern.
