Description

  The present invention relates to a user authentication technique in an information processing terminal, for example.

  Information processing terminals such as smartphones, for example, are developed together with mobile communication network technology that is a communication infrastructure, and it is considered that the number of scenes that many people use in work, private, etc. will increase in the future.

  Along with that, for example, users of smartphone terminals need to be careful not to cause security problems such as information leakage when the smartphone terminal is lost or peeping by a third party on the go. .

  On the other hand, mobile information processing terminals such as smartphone terminals can be released relatively easily so that the user can take out the mobile information processing terminal, for example, from a bag or pocket, for convenience. In some cases, an authentication method that can be used is adopted as an initial setting.

  That is, these portable information processing terminals are required to have an authentication method in consideration of safety and convenience.

  Here, the technique described in Patent Document 1 registers authentication data based on time series data such as acceleration according to the behavior of the mobile phone owner waving his arm in the mobile phone, and the owner himself It is disclosed that the degree of similarity with the data of the arm swinging behavior is obtained, and the personal authentication is performed from the obtained degree of similarity.

  The technique described in Patent Document 2 authenticates a movement pattern when a mobile phone including an acceleration sensor is moved as personal authentication information, and sets or releases a lock function for temporarily locking the operation of the mobile phone. To disclose.

  In addition, the technology described in Patent Document 3 compares the reference behavior pattern registered based on the acceleration information when the owner who owns the mobile phone acts with the acceleration information when the owner acts. , When the behavior mode of the owner is identified, for example, the manner mode or the drive mode is set, which is a function that suppresses the ringing of the mobile phone and informs the status of the caller of the caller by a recorded voice or the like Then, it is disclosed that the mode setting is canceled when another behavior pattern that does not correspond to the mode is continued longer than a predetermined period.

  A general mobile phone terminal or mobile information processing terminal (hereinafter sometimes referred to as an “information processing terminal” or “portable information terminal”) may be used to input a code or a display unit when inputting a password, for example. User authentication is performed on a touch panel or the like that also serves as a unit by means of a gesture operation that is a drawing operation with a fingertip, a pen, or the like, a fingerprint pattern that is biometric information of a user, or face authentication.

  However, each of the authentication methods described above has the following problems.

  For example, when entering a code and gesturing, there is a problem that when a peep is seen by another person, the code and the gesture are easily specified and memorized.

  In addition, for example, a secret code or gesture may leave a trail (that is, a trace at the time of authentication) on the surface of the display screen of the touch panel. There is a possibility of matching with a registered code or gesture.

  In addition, the fingerprint pattern may not be read correctly and easily due to dryness or sweating on the user's fingertip, and in that case, the user may not be able to read the fingerprint pattern. There is a possibility that the information processing terminal cannot be used immediately by trying reading.

  Further, face authentication has a problem that it is possible to impersonate relatively easily by presenting an image such as a photograph to a camera of an information processing terminal, for example. Further, face authentication has a problem that it is difficult to recognize depending on the orientation of the user's face facing the camera of the information processing terminal and the surrounding lighting environment.

  For example, in a portable information terminal such as a smartphone using a touch panel or the like, the user always operates an input unit (button or the like) displayed on the screen while watching the display screen on the touch panel. There is a problem that the operation may be peeped by surrounding people while operating with the line of sight toward the screen of the information terminal.

  Here, the techniques described in Patent Document 1 and Patent Document 2 are used in a space of a certain size when a user holds a mobile phone in his hand, shakes his arm, or draws a predetermined movement pattern. It is necessary to shake or move the mobile phone so that the acceleration sensor or the like mounted on the mobile phone recognizes. Therefore, when a user sees an operation of moving the mobile phone, the surrounding person (others) may learn the movement pattern.

  In addition, for example, when the user visually observes an operation that the user moves to authenticate the mobile phone, there is a problem that the operation does not necessarily feel natural. Therefore, the user needs to select a place where the mobile phone can be moved so that it cannot be seen by people around you. For example, when the user of the mobile phone is in a meeting or in a public place Inconvenient for.

  Note that Patent Document 3 is an opportunity for automatically canceling the setting for suppressing notification of incoming calls and the like by monitoring current behavior such as walking, sitting, standing, and boarding a vehicle, and cannot respond. The purpose is to prevent loss, and the purpose and action are different from those of the present application.

  Patent Document 1 and Patent Document 2 input (operate) a start condition for performing a predetermined authentication so that a user of a mobile phone does not notice that a person in the surrounding area simply looks into it. No mention is made of making it more difficult for people around to impersonate using the mobile phone.

  In addition, Patent Document 1 and Patent Document 2 describe that, for example, a bag carried by the user when authentication is performed so that the user is not easily recognized by surrounding people, such as a bag or a pocket in the user's own clothing. It does not mention that authentication is possible.

  In addition, related technologies including Patent Document 1 and Patent Document 2 are used when the user moves the target portable information terminal and does not match personal authentication information that is a specific movement pattern registered in advance. For example, the display of the display screen of the portable information terminal, other methods, or a combination of these means that the user has failed to set or release (authenticate) the lock function. I didn't mention that.

  Further, Patent Document 1 and Patent Document 2 show that a user who uses a mobile phone or the like performs an operation of authenticating while keeping his eyes on the periphery without staring at a display screen of the mobile phone or the like. It does not mention that authentication can be performed without being noticed by other people and that peeping from surrounding people can be suppressed.

  That is, the main object of the present invention is to provide an authentication control device and the like for authenticating a user such as a terminal safely and easily in order to solve the above-described problems.

The present invention has been made for the purpose of solving the above-described problems.

That is, the authentication control device according to the present invention is
When the device rotates about at least one of the three axes corresponding to the vertical direction, the horizontal direction, and the depth direction of the device detected by the tilt detection function, Rotation direction information representing a combination of clockwise or counterclockwise rotation directions around the rotation axis, and registered rotation direction information in which any combination of the rotation directions when the device rotates is registered. If they match, it is determined that the authentication is successful.

As another aspect of the present invention, a method for controlling an authentication control apparatus according to the present invention includes:
When the device rotates about at least one of the three axes corresponding to the vertical direction, the horizontal direction, and the depth direction of the device detected by the inclination detection means, Rotation direction information representing a combination of clockwise or counterclockwise rotation directions around the rotation axis, and registered rotation direction information in which any combination of the rotation directions when the device rotates is registered. If they match, it is determined that the authentication is successful.

  This object is also achieved by a computer program that implements the above-described authentication control apparatus and control method having the above-described configuration by a computer, and a computer-readable storage medium that stores the computer program. .

  According to the present invention, a user of a terminal or the like can be authenticated safely and easily.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
The configuration of the first embodiment of the present invention will be described. FIG. 1 is a block diagram conceptually showing functions in the authentication control apparatus 1 according to the present embodiment.

  The authentication control apparatus 1 according to the present embodiment is configured to have at least one of the three axes corresponding to the vertical direction, the horizontal direction, and the depth direction of the own apparatus detected by the tilt detection function as a rotation center. Rotation information 3 representing a combination of clockwise or counterclockwise rotation directions around any one of the rotation axes, and any combination of the rotation directions when the device rotates. Is matched with the registered rotation direction information 4 registered, it is determined that the authentication is successful.

  Here, the authentication control apparatus 1 acquires information on the rotation direction when the own apparatus rotates based on the rotation direction information 3 from the tilt detection function. Further, the authentication control device 1 compares the acquired rotation direction information 3 with the registered rotation direction information 4 in which a combination of rotation directions is registered in advance.

  The rotation axis refers to the authentication control device 1 when, for example, a user (not shown in FIG. 1, the same applies hereinafter) facing the operation surface rotates the authentication control device 1. For example, the depth direction, the horizontal direction, and the vertical direction are respectively associated with (assigned to) a three-axis three-dimensional space including the X axis, the Y axis, and the Z axis, and at least one of the three axes. This is a rotation axis when the authentication control device 1 rotates around any one axis.

  The above-described method of associating the depth direction, the horizontal direction, and the vertical direction with the three axes of the X axis, the Y axis, and the Z axis in the authentication control apparatus 1 is an example.

  Moreover, the axis | shaft at the time of rotating an own apparatus may be any axis | shaft, the rotation direction in each rotating shaft may be any direction, and these rotation directions can be combined arbitrarily.

  And a rotation direction is a rotation direction at the time of the authentication control apparatus 1 rotating centering around these axes.

  Further, if the rotation angle when the user performs a rotation operation is equal to or greater than a predetermined rotation angle, the rotated direction is set as the rotation direction. Therefore, the rotation angle can be based on an absolute angle or a relative angle. However, for the convenience of explanation, the authentication control apparatus 1 in the present embodiment will be described as an example that recognizes the rotation angle based on the relative angle.

  That is, when the user rotates the authentication control device 1, the posture of the user holding the authentication control device 1 is used as a base point, and from which rotation axis is centered in which direction of rotation, a predetermined rotation angle or more. The user can be authenticated by, for example, a portable information terminal or the like including the authentication control device 1 by combining the operations of the rotation.

  The authentication result notification 5 represents an authentication result indicating that the authentication is successful when the registration rotation direction information 4 and the rotation direction information 3 match in the authentication control unit 2. Here, the registered rotation direction information 4 is information representing a combination of rotation directions rotating around any one of the rotation axes described above. For example, in the present embodiment, an external storage device (not shown in FIG. 1). Is registered in the figure). The rotation direction information 3 is information relating to a combination of rotation directions in which the authentication control device 1 rotates.

  The authentication result notification 5 may represent an authentication result indicating that the authentication has failed when the registered rotation direction information 4 and the rotation direction information 3 do not match.

  Next, operation | movement of the authentication control apparatus 1 in this embodiment is further demonstrated using a flowchart. FIG. 2 is a flowchart showing authentication processing in the authentication control apparatus 1 according to the first embodiment.

  The authentication control unit 2 acquires the rotation direction information 3 (step S21).

  The authentication control unit 2 is information included in the acquired rotation direction information 3, and a combination of rotation directions rotating around any rotation axis is a combination of rotation directions registered in the registered rotation direction information 4. It is confirmed whether or not they match (step S22).

  If the acquired rotation direction information 3 matches the registered rotation direction information 4 (YES in step S22), the authentication control unit 2 outputs an authentication result notification 5 indicating that they match (step S23).

  If the rotation direction information 3 acquired in step S21 and the registered rotation direction information 4 do not match (NO in step S22), the authentication control unit 2 outputs an authentication result notification 5 indicating that they do not match. (Step S24).

  That is, the authentication control device 1 according to the present embodiment can authenticate safely and easily when the user of the authentication control device 1 is authenticated.

  The reason is that when the user of the authentication control device 1 authenticates the user himself / herself, the user can be authenticated by a rotating operation with a small amount of movement, or a combination thereof, so that it is difficult for the surrounding people to notice, In addition, it is possible to receive an authentication result notification indicating that the authentication has succeeded or failed.

  The first embodiment of the present invention has been described above by taking the configuration and operation described above as examples. However, the present invention described by taking this embodiment as an example is not necessarily limited to such configurations and operations.

<Second Embodiment>
Next, a second embodiment based on the first embodiment will be described with reference to FIGS. In the following description of the present invention, for convenience of description of the apparatus and operation, three-dimensional coordinate (XYZ coordinate) symbols are used in the drawings (FIGS. 5 and 6).

  The configuration of the second embodiment of the present invention will be described. FIG. 3 is a block diagram conceptually showing the authentication control function in the portable information terminal 100 according to the present embodiment.

  The mobile information terminal 100 according to the present embodiment is an example in which an authentication control function is applied to a mobile phone terminal. However, the portable information terminal 100 is not limited to a portable telephone terminal, and includes a portable music player (playback terminal) in addition to a portable information processing terminal.

  The portable information terminal 100 includes a button 101, a gyro sensor 102, a sensor information recording unit 103, a detection result analysis unit 104, an authentication processing unit 105, a screen display unit 106, an authentication information database 107, and an authentication result notification. Part 108.

  Here, the authentication information database 107 in the present embodiment corresponds to the registered rotation direction information 4 in the first embodiment. In addition, the button 101, the gyro sensor 102, the sensor information recording unit 103, the detection result analysis unit 104, the authentication processing unit 105, the screen display unit 106, and the authentication result notification unit 108 in the present embodiment are This corresponds to the authentication control unit 2 in the first embodiment.

  The notification information output by the authentication result notification unit 108 in the present embodiment corresponds to the authentication result notification 5 in the first embodiment.

  Further, in the present embodiment, when the user 200 authenticates himself / herself in the portable information terminal 100, authentication information (described later) based on the rotation direction information 3 generated when the portable information terminal 100 is rotated is used as the authentication information database. 107 is registered in advance as registration authentication information (described later) 107, the button 101 is used as an opportunity when the user 200 inputs the rotation direction information 3, and the portable information terminal 100 is based on the rotation direction information 3. The point which uses the authentication result notification part 108 which notifies the user 200 the result (success or failure) of authenticating authentication information is mainly different from 1st Embodiment.

  Here, the rotation direction information 3 is information such as a rotation direction rotating around any rotation axis when the portable information terminal 100 rotates, a rotation angle thereof, an angular velocity at that time, and the like. Are sequentially output from, for example, the gyro sensor 102 in accordance with the combination of rotation operations.

  Here, the rotating shaft will be described with reference to FIG. FIG. 5 is a diagram illustrating a direction in which a rotation operation is performed when the user 200 is authenticated in the portable information terminal 100 according to the present embodiment.

  As shown in FIG. 5, the rotation axis of the portable information terminal 100 is such that, for example, the center of gravity of the portable information terminal 100 when the user 200 stands upright and faces the specified display operation surface of the portable information terminal 100. The axis representing the top and bottom with the origin as the Z axis, the axis representing the left and right as the Y axis, and the axis representing the front and back as the X axis. Note that the method of determining the origin of the three axes in the portable information terminal 100 is not limited to the method described above.

  Similarly, the rotation operation will be described with reference to FIG. The Z-axis represents the up-down direction of the portable information terminal 100 facing the user 200, and the mobile information is respectively defined with the upper direction of the Z-axis as the + (plus) Z-axis direction and the lower direction as the-(minus) Z-axis direction. It corresponds to the terminal 100.

  The direction in which the user 200 rotates the portable information terminal 100 with the Z axis as viewed from the user 200 facing the user 200 as the central axis is rotated counterclockwise from the −Z axis direction to the Z axis when viewed from the + Z axis direction. The rotation operation is referred to as a “right horizontal” direction, and the rotation operation that rotates clockwise about the Z axis is also referred to as a “left horizontal” direction.

  Similarly, the Y axis represents the left and right (lateral) direction of the portable information terminal 100 facing the user 200, and the right direction of the Y axis is the + Y axis direction and the left direction is the -Y axis direction. 100.

  The direction in which the portable information terminal 100 is rotated about the Y axis viewed from the user 200 facing the user 200 as a central axis is a rotation operation that rotates counterclockwise from the −Y axis direction to the Y axis when viewed from the + Y axis direction. The rotation operation for rotating the Y-axis in the clockwise direction will be referred to as the “down” direction.

  The X axis represents the front-rear direction of the mobile information terminal 100 facing the user 200, the + X-axis direction opposite to the user 200 facing the front (the rear representing the depth), and the front direction of the user 200. -Correspond to each portable information terminal 100 as the X-axis direction.

  Then, the direction in which the portable information terminal 100 is rotated about the X axis viewed from the user 200 facing the user 200 as a central axis is a rotation operation that rotates clockwise from the −X axis direction to the X axis when viewed from the + X axis direction. The rotation operation that rotates counterclockwise about the X axis is also referred to as the “left” direction.

  As shown in FIG. 5, the orientation when the user 200 faces the portable information terminal 100 in the initial stage is referred to as “front horizontal”.

  The authentication information is determined by the detection result analysis unit 104 described later based on the rotation direction information 3 output from the gyro sensor 102 in accordance with the rotation operation described above, the rotation angle, the angular velocity, and the like. This is information converted into information combining the rotation directions.

  Further, in the present embodiment, the above-described authentication information used for authenticating the user 200 to the portable information terminal 100 further includes authentication start information and authentication operation information in time series, each of which includes combination information in the rotation direction. Including.

  That is, the authentication start information is information indicating that the authentication is started, and the authentication operation information can be rotated following the authentication start information when the authentication start information is correct. Is information that can be authenticated by a rotation operation.

  Next, the button 101 is an operation button that can be pressed by the user 200 who uses the portable information terminal 100, and becomes an opportunity when inputting authentication information. That is, the user 200 can input authentication start information and authentication operation information following the authentication start information by rotating the portable information terminal 100 after pressing the button 101. .

  The button 101 can also be used as a trigger when registering the registered rotation direction information 4 (registered authentication information) in the authentication information database 107.

  The button 101 may be a hardware (Hardwear: hereinafter abbreviated as “HW”) button or a software (Software: hereinafter abbreviated as “SW”) button, and the others. It may be a user interface (UI) that triggers the input of the rotation operation.

  The SW button is an input button that can be input by displaying a button on the screen of the touch panel on the screen display unit 106 of the portable information terminal 100 and touching the displayed button, for example.

  Next, the gyro sensor 102, which is an example of the tilt detection function, uses the Z axis, the Y axis, and the X axis (see FIGS. 5 and 6) as rotation centers when the user 200 rotates the portable information terminal 100. The frequency representing the relative rotation angle of the rotating terminal is output as a numerical value.

  Here, in the present embodiment, the reference representing the rotation angle is, for example, the attitude of the portable information terminal 100 when the user 200 presses the button 101 when starting the operation of rotating the portable information terminal 100. Assuming that the angles represented by the three axes associated with the portable information terminal 100 are 0 degrees with respect to the respective axes.

  Next, after the user 200 presses the button 101 on the portable information terminal 100, the sensor information recording unit 103 is output from the gyro sensor 102 according to the operation content that the user 200 rotates the portable information terminal 100. The value of the rotation direction information 3 is detected, and the detected rotation direction information 3 is recorded.

  The information recorded in the sensor information recording unit 103 follows the rotation direction information 3 (rotation direction, rotation angle, angular velocity) that is the basis of the above-described authentication start information (rotation direction) indicating that authentication is started. The rotation direction information 3 (rotation direction, rotation angle, angular velocity) that is the basis of the above-described authentication operation information (rotation direction) representing the authentication operation is recorded in this order.

  The sensor information recording unit 103 transmits the recorded value of the rotation direction information 3 to the detection result analysis unit 104.

  The detection result analysis unit 104 converts the rotation information 3 (rotation direction, rotation angle, angular velocity) received from the sensor information recording unit 103 into authentication information (rotation direction).

  The sensor information recording unit 103 discards the recorded rotation direction information 3 in the sensor information recording unit 103 after transmitting the value of the recorded rotation direction information 3 to the detection result analysis unit 104.

  Then, the authentication information database 107 registers in advance registration authentication information to be compared with the converted authentication information in order to confirm whether or not the user 200 is the user.

  More specifically, the registration authentication information registered in the authentication information database 107 includes information in which registration authentication start information described later and registration authentication operation information are associated with each other.

  That is, the authentication start information and the authentication operation information included in the authentication information converted into the rotation direction based on the rotation direction information 3 input by the user 200 by rotating the portable information terminal 100 are registered authentication information. The registration authentication start information and the registration authentication operation information included in each are compared in order.

  Note that modes for registering registered authentication information in the authentication information database 107 include a rotation mode and a setting mode.

  The rotation mode is a mode in which the user 200 actually rotates the portable information terminal 100 to register desired registration authentication start information and registration authentication operation information in the authentication information database 107.

  The registration method at this time can be started from registration of registration authentication start information using the sensor information recording unit 103 by the user 200 pressing the button 101, for example.

  Further, when the registration authentication start information has been successfully registered, for example, the screen display unit 106 may display that the registration has been successful. Subsequently, the user 200 registers registration authentication operation information by the same operation.

  In the setting mode, the authentication processing unit 105 and the screen display unit 106 are used to directly register the combinations of desired rotation directions corresponding to the registration authentication start information and the registration authentication operation information in the authentication information database 107 in order. .

  Further, the portable information terminal 100 may have a trial mode for confirming in advance whether or not the authentication can be performed correctly correctly using the registered registration authentication information. At that time, the user 200 sets the mobile information terminal 100 to the trial mode, and presses the button 101 to rotate the mobile information terminal, for example, and whether or not the user 200 is correctly authenticated as registered. Can be confirmed in advance.

  Then, the detection result analysis unit 104 determines the Z axis shown in FIG. 5 based on the information about the rotation direction, the rotation angle, and the angular velocity that the rotation direction information 3 received from the sensor information recording unit 103 has. Any of rotation in the right horizontal direction or left horizontal direction with the rotation center, rotation in the upward or downward direction with the Y axis as the rotation center, and rotation in the right direction or left direction with the X axis as the rotation center It is converted into authentication information that represents such rotation.

  Further, the detection result analysis unit 104 may sequentially convert it into authentication information every time it receives one rotation direction information 3. The detection result analysis unit 104 receives a plurality of rotation direction information collectively, and receives the rotation direction information 3 in the order received. You may convert into authentication information sequentially.

  In addition, a method of determining the rotation direction from the rotation direction information 3 and converting it into authentication information based on the rotation angle and the angular velocity in the detection result analysis unit 104 will be described later.

  Then, the detection result analysis unit 104 transmits the converted authentication information to the authentication processing unit 105.

  Here, the sensor information recording unit 103 and the detection result analysis unit 104 described above are a series of processes described later with reference to FIG. 4, that is, recording and transmission of operation contents by the sensor information recording unit 103, and detection results. The conversion and transmission to the authentication information by the analysis unit 104 are repeated in order for authentication start information indicating authentication start, which is information constituting the authentication information, and authentication operation information indicating performing original authentication.

  The authentication processing unit 105 also registers the authentication start information and the authentication operation information included in the authentication information received from the detection result analysis unit 104 with the registration authentication start information and the registration authentication operation information registered in advance in the authentication information database 107. And compare each in turn.

  At that time, if the authentication processing unit 105 confirms that the previous authentication start information matches the registered authentication start information registered in the authentication information database 107, the authentication processing unit 105 reduces the range of authentication operation information that is subsequent information. Can be identified.

  Note that the method for specifying the range of the authentication operation information is not limited to the method described above in the present embodiment. For example, when the rotation operation is recorded in the sensor information recording unit 103, the rotation direction information serving as the authentication start information is recorded. It is also possible to take a method such as providing a predetermined non-operation period later or pressing any button while inputting the rotation direction information serving as authentication start information.

  Also, if the previous authentication start information does not match the registered authentication start information registered in the authentication information database 107, the authentication processing unit 105 stops specifying the range of the next authentication operation information and performs authentication. It shall return to the first state that can be started.

  Next, if the previous authentication start information matches the registration authentication start information, the authentication processing unit 105 compares the current authentication operation information with the registered authentication operation information registered in the authentication information database 107 in advance. Whether authentication has succeeded or failed is determined according to whether the authentication operation information matches or does not match the registered authentication operation information.

  When the mobile information terminal 100 is successfully authenticated, the screen display unit 106 displays a screen after authentication on the user 200. When the mobile information terminal 100 fails in authentication, the screen display unit 106 may display on the screen that the authentication has failed.

  However, when the user 200 performs an operation of rotating the portable information terminal 100, the authentication start information and the registration authentication start information are not referred to each time the user 200 performs a rotation operation related to the authentication start information and the authentication operation information. Each time the authentication operation information and the registered authentication operation information are matched in order, it is possible to recognize that the authentication has been performed more clearly than a simple vibration by receiving a tactile sensation to be described later.

  Here, the tactile sensation is different from simple vibration and is to present the user 200 with a pseudo-feel using the perception or illusion of the user 200. For example, the mobile information touched by the user 200 This is to convey a force pattern intended to allow the terminal 100 to more clearly identify whether authentication has succeeded or failed.

  More specifically, for example, if the portable information terminal 100 is held in a familiar place such as a bag carried by the user 200 or a pocket of the user 200's own clothes, the portable information terminal 100 is rotated at that place. Even if the user does not look at the screen display unit 106 of the portable information terminal 100, the user 200 has succeeded or failed in the authentication of the user by the portable information terminal 100 by experiencing the tactile sensation presented. It is possible to clearly recognize whether or not

  In addition, when the authentication start information and the registration authentication start information, or the authentication operation information and the registration authentication operation information do not match, the user 200 presents a tactile sensation different from that presented when the user information matches. By receiving, it can be clearly recognized that there is a mismatch.

  As a result, the user 200 does not look at the screen display unit 106, and if it matches, the authentication of the portable information terminal is completed, or if it does not match, for example, after pressing the button 101 again, In order to re-enter authentication information (authentication start information or authentication operation information), the mobile information terminal 100 can retry the rotation operation.

  The portable information terminal 100 can notify (present) whether the authentication has succeeded or failed to the user 200 using the tactile sensation described above in the authentication result notifying unit 108 shown in FIG. In this case, the authentication result notification unit 108 may be mounted with an actuator (drive device) (not shown) that generates a tactile force sense.

  An actuator that generates a tactile sensation is an element that can vibrate a member including a housing and a screen of the portable information terminal 100 by converting a change in voltage such as a piezoelectric element into a change in vibration. Can be adopted.

  Further, as a driving pattern for driving the actuator, for example, a haptic pattern programmed to generate a pseudo touch may be used.

  Here, as an example, the haptic sensation presented when the authentication is successful is presented once for a period of about 0.5 seconds, for example. The tactile sensation to be presented when authentication fails is presented twice, for example, at a period of about 0.3 seconds and at intervals of about 0.3 seconds.

  For the sake of explanation, the period, the time interval, and the number of times when the haptic sensation is generated are described as an example. However, the type and strength of the haptic pattern are not limited to this.

  In addition to the notification method using the tactile force sense, the authentication result notification unit 108 notifies the user 200 in combination with a general notification method such as sound including sound, light, or simple vibration. You may do it.

  Next, an operation in which the user 200 rotates the portable information terminal 100 according to the present embodiment will be described with reference to FIG.

  FIG. 5 is a diagram for explaining a rotation operation by a user necessary for an authentication operation by the portable information terminal 100 according to the second embodiment.

  As described above, the rotation operation that allows the user 200 to rotate the portable information terminal 100 is performed when the user 200 faces the predetermined operation surface of the portable information terminal 100, for example. It consists of two left and right rotation directions that rotate about three axes consisting of Z axis, Y axis, and X axis corresponding to the vertical direction, horizontal direction, and depth direction in 100, that is, right horizontal and left horizontal respectively. , Up and down, left and right, a total of six rotation operations.

  Then, as shown in FIG. 6, the sensor information recording unit 103 in the portable information terminal 100 sets the range of rotation operation in each axis in units of 90 degrees, for example, with the center of gravity as the origin of three axes in the portable information terminal 100. The virtual section is divided and recognized as one rotation operation when the individual section is rotated at a rotation angle larger than a predetermined rotation angle.

  FIG. 6 is a diagram illustrating a spatial range of the rotation operation required for the authentication operation of the portable information terminal 100 according to the second embodiment.

  Then, the detection result analysis unit 104 converts the rotation direction information recorded in the sensor information recording unit 103 into authentication information, for example, as a rotation angle recognized as the rotation in the virtual section described above, for example, There are three types of thresholds.

  That is, it is possible to set the rotation angle so that it can be switched in three steps, such as “large” at 15 degrees, “medium” at 10 degrees, and “small” at 5 degrees in order of increasing rotation angle.

  Based on this threshold, the detection result analysis unit 104 converts the rotation angle for each rotation direction into authentication information, and transmits the converted authentication information to the authentication processing unit 105.

  Specifically, when the threshold value of the rotation angle when rotating the portable information terminal 100 is set to 10 degrees (that is, the setting of the rotation angle is “medium”), the user 200 determines, for example, the + X axis direction When it is rotated 10 degrees to the left, the authentication information is converted to “left” in the X axis.

  Furthermore, in addition to the rotation angle described above, the detection result analysis unit 104 converts, for example, three kinds of threshold values as angular velocities when converting (determining) the rotation direction information recorded in the sensor information recording unit 103 into authentication information. Have

  That is, in order of decreasing angular velocity, “slow” can be set in three stages, such as 10 rad / s (radian per second), “medium” 20 rad / s, and “fast” 30 rad / s. is there.

  Based on the angular velocity threshold value, the detection result analysis unit 104 performs the rotational operation that indicates a rotation angle that exceeds the rotation angle threshold value (for example, “medium”: 10 degrees) in the rotation direction described above. If this threshold value is exceeded, the rotation direction can be determined.

  Specifically, when the threshold of the angular velocity when rotating the portable information terminal 100 is set to 20 rad / s (that is, the angular velocity is set to “medium”), for example, the user 200 is faster than this angular velocity. If it is rotated, the rotation direction based on the rotation angle described above can be determined.

  On the other hand, when the user 200 rotates the portable information terminal 100 at an angular velocity slower than the set angular velocity, the authentication start information is not determined without determining the rotation direction based on the rotation angle described above. It is not recognized as authentication operation information. In that case, the portable information terminal 100 determines that the authentication information does not match the registered authentication information.

  When the user 200 rotates the portable information terminal 100 continuously in the same rotation direction, the user 200 can continuously rotate at a rotation angle and an angular velocity that can be recognized by the detection result analysis unit 104.

  However, the user 200 returns slowly to the angle at which the first rotation is started at an angular velocity slower than the set angular velocity, and continuously rotates the subsequent rotation operation faster than the set angular velocity, thereby continuously moving in the same rotational direction. Can be rotated.

  Next, data registered in the authentication information database 107 will be described with reference to FIG. FIG. 7 is a diagram conceptually illustrating the relationship between registration authentication start information and registration authentication operation information when authenticating the user 200 in the portable information terminal 100 according to the second embodiment.

  The data (table) shown in FIG. 7 is stored in the authentication information database 107 in a state where the registration authentication start information and the registration authentication operation information are associated with each other.

  As described above, the authentication processing unit 105 authenticates the subsequent portable information terminal 100 when the authentication start information accompanying the rotation operation matches the registration authentication start information to be compared with the authentication start information. The range of the authentication operation information is specified, the authentication operation information is compared with the registered authentication operation information registered in the authentication information database 107, and whether or not the authentication has succeeded or failed depends on whether or not the comparison result matches. judge.

  Then, as shown in FIG. 7, the registration authentication start information indicates that a right rotation is performed once toward the right horizontal, that is, the + X axis, and then a left rotation is performed once toward the left horizontal, that is, the + X axis. Show.

  The user 200 may perform the above-described rotation operation of the authentication start information after pressing the button 101, or may perform the above-described rotation while pressing any button.

  In addition, when the authentication processing unit 105 correctly recognizes the authentication start information, the response indicating that the authentication has been performed is described above with respect to the screen display, tactile sensation, sound, light, vibration, or a combination thereof. It is possible to feed back the authentication result notification based on such notification period, interval, and number of times to the user 200.

  Next, when the authentication processing unit 105 can correctly recognize the authentication start information, the authentication processing unit 105 notifies the user 200 of the authentication result notification in the authentication start information by the method described above, and further analyzes the authentication operation information. .

  That is, as shown in the registration authentication operation information shown in FIG. 7, left horizontal (one rotation left toward + Z axis), right horizontal (one rotation right toward + Z axis), right horizontal (+ Z axis) Compared to each other in the order of clockwise rotation once (upward), upward (upper forward tilt along the Y axis once), and lower (lower forward tilt along the Y axis).

  Note that the user 200 may return to “front horizontal”, which is the posture in which the authentication operation is started when the button 101 is finally pressed.

  Then, when the authentication processing unit 105 correctly recognizes the above-described authentication operation information, a response indicating that the authentication operation information has been recognized is displayed on the screen, tactile sensation, sound, light, vibration, or a combination thereof. It is possible to feed back (provide) the authentication result notification based on the notification period, interval, and number of times as described above to the user 200.

  Note that the authentication result notification unit 108 may output an authentication result notification for notifying that authentication has been performed, as authentication start information and authentication operation information, or only when authentication operation information is authenticated. It may be.

  Next, the operation in the present embodiment will be described in more detail using a sequence diagram. FIG. 4 is a sequence diagram for explaining an authentication operation in the portable information terminal 100 according to the second embodiment.

  The user 200 activates the authentication processing unit 105 by pressing the button 101 (step S_A1).

  The authentication processing unit 105 temporarily cancels the operation start when the authentication information is input if the no-operation state in which the rotation operation is not performed for a predetermined period after the button 101 is pressed. You may do it.

  The predetermined period at that time is, for example, 3 seconds. In other words, the user 200 may start inputting authentication information within 3 seconds after the button 101 is pressed.

  In addition, the sensor information recording unit 103 discards the operation content of the rotation operation input so far and authenticates if no operation is continued for a predetermined period after the button 101 is pressed. As an opportunity to start an operation when inputting information, it may be temporarily canceled. The predetermined period described above may be, for example, 3 seconds.

  To complete the authentication operation, the user 200 may press the button 101 again and start the rotation operation from the beginning. Note that the above-described number of seconds for the non-operation period is an example and is not limited.

  The sensor information recording unit 103 and the authentication processing unit 105 suppress unintentional authentication by another person who tries the authentication operation by detecting the no-operation state as described above and setting the state before the authentication start. Can do.

  The activated authentication processing unit 105 causes the sensor information recording unit 103 to detect the rotation direction of the rotation axis detected by the gyro sensor 102 (not shown in FIG. 4), the rotation angle, and the value of the angular velocity (rotation direction). Information), that is, an instruction to record the operation content (step S_A2).

  The sensor information recording unit 103 starts recording the rotation direction information output from the gyro sensor 102 based on the instruction from the authentication processing unit 105 (step S_A3).

  The user 200 rotates the portable information terminal 100 (step S_A4).

  The sensor information recording unit 103 records the rotation direction information output from the gyro sensor 102 while the user 200 performs the rotation operation of the portable information terminal 100 (NO in step S_A5).

  Further, the rotation operation by the user 200 can be stopped by providing a non-operation period. The stop time at that time is, for example, 3 seconds.

  Further, the authentication processing unit 105 may recognize that the rotation operation has stopped when the user 200 presses the button 101 again, for example. In addition, for example, the sensor information recording unit 103 may hold down any button during the rotation operation and recognize that the rotation operation has stopped when the button is stopped. Is possible.

  When the sensor information recording unit 103 recognizes that the rotation operation of the portable information terminal 100 by the user 200 has been stopped due to the non-operation state or the button operation as described above (YES in step S_A5), the sensor information recording unit 103 Recording of the value related to the rotation direction information that is the content of the rotation operation that has been output is stopped (step S_A6).

  And the sensor information recording part 103 transmits the information which recorded the rotation direction which is the value regarding the recorded rotation direction information, a rotation angle, and an angular velocity to the detection result analysis part 104 (step S_A7).

  The detection result analysis unit 104 uses the rotation angle and angular velocity threshold values (not shown in FIG. 4) described above as the values represented by the rotation angle and angular velocity included in the rotation operation content received from the sensor information recording unit 103. Are converted into authentication information representing a combination of the rotation directions (right horizontal or left horizontal, up or down, right or left), and transmitted to the authentication processing unit 105 (step S_A8).

  Note that the sensor information recording unit 103 may exclude in advance a rotation operation that is not intended by the user 200 (that is, a rotation operation slower than a predetermined angular velocity) using the angular velocity information included in the rotation direction information as described above. it can. In that case, the sensor information recording unit 103 may transmit only the rotation direction and the rotation angle to the detection result analysis unit 104 among the values regarding the recorded rotation direction information in step S_A7.

  Next, the authentication processing unit 105 compares the authentication start information received from the detection result analysis unit 104 with the registered authentication start information stored in the authentication information database 107 (not shown in FIG. 4), and compares the authentication start information. And the target range of the authentication operation information necessary for authenticating the portable information terminal 100 following the authentication start information is specified (step S_A9).

  Here, the target range of authentication operation information necessary for authentication is authentication information excluding authentication start information.

  Then, the authentication processing unit 105 determines the authentication operation information by comparing the authentication operation information specified in step S_A9 described above with the registered authentication operation information stored in advance in the authentication information database 107 (step S_10). .

  If the authentication process in step S_A10 succeeds in authentication (that is, the authentication operation information matches) (YES in step S_11), authentication processing unit 105 indicates that authentication is successful by authentication result notifying unit 108. An authentication success notification is output (step S_A12).

  On the other hand, if the authentication processing in step S_A10 fails in authentication (that is, the authentication operation information does not match) (NO in step S_A11), authentication processing unit 105 confirms that authentication has failed by authentication result notifying unit 108. An authentication failure notification is output (step S_A13).

  If authentication is successful (that is, the authentication operation information matches) in the authentication processing in step S_A10 (YES in step S_11), the authentication processing unit 105 displays a screen display unit 106 not shown in FIG. To output the screen after successful authentication.

  As described above, the user 200 receives the presentation of the haptic sensation described above, for example, in the authentication result notification unit 108 and knows not only that the authentication is successful but also the case where the authentication fails without looking at the screen. Therefore, when authentication fails, it can be retried until the authentication is successful, for example, in a bag or a pocket of clothes of the user 200.

  By the authentication control function included in the portable information terminal 100 according to the present embodiment, the user 200 can enjoy the following effects.

  The first effect is that the portable information terminal 100 according to the present embodiment can authenticate the user 200 safely.

  The reason is that the user 200 has a small rotation operation when authenticating the user 200 itself to the portable information terminal 100, and it is difficult for the surrounding people to peep at the act of authentication.

  Further, the portable information terminal 100 can perform authentication even in a state where it is held in a bag or pocket, and it is not necessary for surrounding people to learn the authentication operation.

  In addition, since the authentication start condition is to press the button when authenticating, and the original authentication operation information is input after inputting the authentication start information, it is difficult for others to impersonate, and the portable information terminal This is because it is not erroneously authenticated due to vibration or the like when carrying the 100.

  The second effect is that the portable information terminal 100 according to the present embodiment can recognize the authentication result when the user 200 performs the authentication operation without looking at the screen.

  The reason is that, as a result of the user 200 authenticating, the portable information terminal 100 is not only when authentication is successful, but also when authentication fails, for example, display on the display screen, tactile sense, sound, This is because the user 200 is notified by light, vibration, or a combination of notification methods.

  In addition, the notification method described above can adopt different notification methods depending on whether authentication is successful or failure, and the user 200 can clearly authenticate without looking at the screen display. The result can be recognized, and if necessary, authentication can be retried without looking at the screen display.

  As a third effect, the portable information terminal 100 according to the present embodiment can be used by anyone, both young and old.

  The reason is that when the user 200 authenticates the user 200 himself / herself with the portable information terminal 100, the user 200 only needs to perform an operation of rotating while holding the portable information terminal 100 in his / her hand, and does not involve a large operation. It is.

  The fourth effect is that since the portable information terminal 100 according to the present embodiment can restrain the display screen that the user 200 views and the third party who tries to peep at the contents to be operated, it is safe. Authentication operation can be realized.

  The reason is that, when the user 200 authenticates the user 200 itself to the portable information terminal 100, the user 200 does not need to concentrate the line of sight on the portable information terminal 100, and performs an authentication operation while looking at the surroundings. It is because it can do.

  In addition, the user 200 can perform an authentication operation in his / her bag or in his / her clothes, for example, in a pocket, and during that time, looking around can prevent peeping from others. Can do.

  The fifth effect can be easily realized if the portable information terminal 100 according to the present embodiment is a portable information terminal on which the gyro sensor 102 is mounted.

  The reason is that the portable information terminal 100 can be realized only by modifying software in the portable information terminal in which the gyro sensor 102 is mounted.

  If the authentication fails because the authentication information does not match, the user 200 can try the upper limit number of times allowed in advance. If the upper limit number is exceeded, the user 200 cannot be authenticated. It is possible to

  As another effect, the user 200 can prevent unexpected contact with a third party or an obstacle when using the portable information terminal 100 while walking, for example.

  The reason is that the user 200 who operates the portable information terminal 100 does not need to stare at the display screen in order to perform the rotation operation, so that the field of view can be widened and the surroundings can be looked around.

  That is, the portable information terminal 100 according to the present embodiment can authenticate the confirmation of the owner of the mobile phone terminal or the like by a method that is difficult to impersonate a third party and that is excellent in safety and convenience. it can.

  Further, the present embodiment is based on the first embodiment. Therefore, this embodiment has the same effects as those of the first embodiment.

  That is, according to this embodiment, it is possible to enjoy the effect that a user such as a terminal can be authenticated safely and easily.
