With reference to FIG. 1, the structure of the authentication apparatus mounted on the mobile phone of the present invention will be described in detail.
The authentication apparatus includes an acceleration sensor unit 10, an acceleration information detection unit 11, an acceleration personal authentication registration unit 12, a personal authentication information storage unit 13, a personal authentication information authentication unit 14, and a mobile phone lock unit 15.

The acceleration sensor unit 10 detects acceleration information of the mobile phone. The acceleration information has three-dimensional vector information. That is, when the vertical x, horizontal y, and height z are set, the acceleration sensor unit 10 detects the three-dimensional moving direction of x, y, z and the moving amount (size) of the mobile phone. The three-dimensional reference point can be arbitrarily set. For example, the position at the time of starting authentication may be used, or a predetermined position may be used.
The acceleration information detection unit 11 receives acceleration information from the acceleration sensor unit 10 and passes it to the acceleration personal authentication registration unit 12.
The acceleration personal authentication registration unit 12 records acceleration information while the personal authentication information registration mode is set. A plurality of pieces of acceleration information can be registered in the memory. For example, in the case of an operation such as once up and down and twice left and right, six pieces of information “up, down, left, right, left, right” are recorded.
The personal authentication information storage unit 13 stores acceleration information until the personal authentication information registration mode ends as one personal authentication information. At this time, the acceleration information of the terminal after a menu operation (authentication pattern registration menu) on the terminal or an arbitrary operation such as after inputting a specific password is stored. The movement of the terminal may be, for example, drawing a triangle three times or writing one's name in the air.
The personal authentication information authentication unit 14 acquires acceleration information from the acceleration information detection unit 11, and compares the acceleration information pattern recorded in the acceleration personal authentication registration unit 12 with the storage pattern of the personal authentication information storage unit 13. If the patterns match, the mobile phone lock unit 15 is instructed to release the mobile phone lock function and use the mobile phone function. The personal authentication information authentication unit 14 may be integrated with the acceleration personal authentication registration unit 12.
The mobile phone lock unit 15 locks (locks) the use of mobile phone functions, for example, the function of making calls except emergency calls (110, etc.), browsing the phone book, reading and writing mails, etc. To be limited. This lock is released by the personal authentication information authentication unit 14.

  The mobile phone lock includes a lock for predetermined software such as a mobile phone OS and a telephone directory, a lock for a predetermined operation key (input interface) of the mobile phone, a lock for a display device (output interface) of the mobile phone, In addition, there is a lock for an opening / closing mechanism of a folding cellular phone.

Next, the operation of the first exemplary embodiment of the present invention will be described in detail with reference to FIG.

((F) of FIG. 1). If the personal authentication information acquired from the personal authentication information storage unit 13 and the pattern of acceleration information acquired from the acceleration information detection unit 11 do not match, the process is terminated without releasing the lock.

Note that the movement of the mobile phone at the time of authentication may be the same as the movement pattern even if it is not the same operation as when the personal authentication information is registered.
For example, when authenticating the action of drawing a circle three times, even if the movement amount (size) and time are slightly different, such as the size of the circle and the time to draw a circle once, but the shape moving the terminal is the same Recognize that the patterns match. That is, circles, triangles, and squares are different patterns, but large circles and small circles are treated as the same pattern. However, at this time, the operation of drawing a circle on the top and bottom and the operation of drawing a circle on the left and right are different patterns.

The configuration of the second exemplary embodiment of the present invention will be described in detail.
A mobile phone function (for example, a redial part) corresponding to the acceleration information pattern is registered in advance, and the mobile phone is registered by moving the mobile phone, for example, three times up and down and twice left and right. Embodiments such as automatically calling functions are conceivable.

With reference to FIG. 3, the operation when registering the mobile phone function according to the acceleration information pattern will be described in detail.
(1) Step S201
First, the mobile phone is set to a personal authentication information registration mode for personal authentication information registration.
(2) Step S202
Next, the acceleration sensor 10 detects the movement of the mobile phone (for example, 3 times up and down, 2 times left and right, etc.) and passes the acceleration information related to the movement of the mobile phone to the acceleration information detection unit 11 ((( a)).
(3) Step S203
Next, the acceleration information detection unit 11 passes the acceleration information from the acceleration sensor 10 to the acceleration personal authentication information registration unit 12 ((b) in FIG. 1).

(5) Step S205
When the personal authentication information registration mode ends, the acceleration personal authentication information registration unit 12 ends registration in the personal authentication information storage unit 13. The personal authentication information storage unit 13 stores the acceleration information so far as one personal authentication information.
(6) Step S206
Next, when the mobile phone function corresponding to the personal authentication information is designated, the personal authentication information storage unit 13 stores the designated mobile phone function and the personal authentication information together.

  As another method, the target mobile phone function is specified first, then the personal authentication information registration mode is set to register the personal authentication information, and the personal authentication is performed on the previously specified mobile phone function. The information may be associated with and stored in the personal authentication information storage unit 13. For example, when the personal authentication information registration mode is started, the mobile phone function is designated.

  The second embodiment of the present invention makes it possible to execute a registered mobile phone function in response to the movement of the mobile phone.

  For example, when the mobile phone moves with a predetermined movement, the personal authentication information authentication unit 14 automatically executes a mobile phone function corresponding to the pattern of the operation. Alternatively, a control unit (not shown) of the mobile phone granted permission from the personal authentication information authentication unit 14 automatically executes the mobile phone function.

  In addition, the present invention can be used in a folding cellular phone such that the cellular phone automatically opens in accordance with a specific acceleration information pattern or the movement of the cellular phone.

  Moreover, according to the present invention, the present invention can be applied to an application such as an authentication device using a device having a function capable of detecting a moving distance.

  In the above description, a mobile phone has been taken as an example, but actually, an object to which the present invention is applied is not limited to a mobile phone. For example, the present invention can be applied to PDAs, portable game machines, and portable music players. In addition, the present invention can be applied to a desktop personal computer that is a fixed terminal by authenticating the movement of a small input device such as a mouse.

  Furthermore, you may limit the timing which performs authentication. For example, authentication is performed for the movement of the mobile phone made in accordance with the ring tone (ringtone, etc.) of the mobile phone. In addition to the ring tone, music can be played for a certain time when a predetermined button is pressed, and the mobile phone movement performed while the music is playing can be authenticated. At this time, sound may be used instead of music. For example, when a predetermined button is pressed, an instruction such as “Please perform the first operation” is given by voice at a predetermined interval, and the mobile phone movement performed in response to the instruction is authenticated. Like that.

  As described above, in the present invention, personal authentication is not performed using a four-digit password, biometric data such as fingerprints, glows, and vein patterns, but is not limited to a mobile phone. Use a movement pattern. Specifically, a mobile phone having an acceleration sensor device is combined with an acceleration detection unit, an acceleration personal authentication information registration unit, a personal authentication information storage unit, and a personal authentication information authentication unit to move when the mobile phone is moved. It is characterized by a personal authentication method that authenticates a pattern as personal authentication information and sets / cancels a lock function of a mobile phone.

  Actually, in addition to the authentication according to the present invention, other authentication technologies such as a conventional four-digit code number and biometric authentication using biometric data such as fingerprints, glows and vein patterns are used. Also good. In this case, authentication is performed at least once according to the present invention, and authentication is performed using at least one of other authentication techniques. Thereby, a stronger and safer security function can be realized.

  In the present invention, the movement pattern of moving the mobile phone is used as authentication information, and the number of combinations and movement patterns are unlimited by setting no limitation on the combination with the three-dimensional direction (two times up and down, 3 left and right). , 5 times before and after, etc.) even if the moving distance is slightly different, there is an effect that it is not erroneously recognized.

  That is, in the present invention, the moving direction of the mobile phone by the acceleration sensor is detected, and this moving pattern is used as personal authentication information together with the three-dimensional direction (up and down, left and right, front and back), the moving distance, and the moving time. Infinite combinations are possible, and by providing individual characteristics, it is possible to ensure the robustness of the authentication function that others cannot imitate.
