The information and gesture setting information are updated and stored with new user authentication setting information and gesture setting information.

In addition, the server storage unit 33 may recognize the terminal identification information of the mobile terminal 10 and store it together with user authentication setting information and gesture setting information received through the server transmission and reception unit 31.

When the server control unit 35 receives the user authentication input information and gesture input information through the server transmission and reception unit 31, the user controller collects user authentication setting information from the server storage unit 33 and compares the user authentication input information with the server. The gesture setting information is collected from the storage unit 33 and compared with the gesture input information.

At this time, the terminal identification information stored in the server storage unit 33 is searched for by referring to the terminal identification information of the corresponding mobile terminal 10 which has transmitted the user authentication input information and gesture input information, and then finds the corresponding terminal identification information. The user authentication setting information may be collected from the storage unit 33 and compared with the user authentication input information, and the gesture setting information may be collected from the server storage unit 33 and compared with the gesture input information.

Upon receiving the confirmed matching signal, in order to generate the other input information, the user authentication data is input to generate user authentication input information, or the movement of the mobile terminal 10 is detected to generate gesture setting information.

For example, when the server controller 35 first receives the user authentication input information from the mobile terminal 10 through the server transmitter / receiver 31, it is determined that the server controller 35 matches the user authentication setting information stored in the server storage 33. . If the result of the determination matches, the server controller 35 transmits the match signal to the mobile terminal 10 through the server transmitter / receiver 31. On the other hand, if there is a mismatch, the server control unit 35 transmits the warning message output signal through the server transmission and reception unit 31.

When the mobile terminal 10 receives the matching signal, the mobile terminal 10 recognizes that the authentication by the user authentication information is successful as a guide message regarding the input of an unauthenticated gesture such as 'start gesture authentication'. It can be done.

On the other hand, when the mobile terminal 10 receives the warning message output signal, it outputs a warning message. Thereafter, the authentication process may be repeated by re-inputting a plurality of strings or voices, biometric images, and fingerprints to release the lock setting of the mobile terminal 10.

Subsequently, the server controller 35 receives the gesture input information from the mobile terminal 10 through the server transmitter / receiver 31 and determines that the gesture input information matches the gesture setting information stored in the server storage 33. If the result of the determination matches, the server controller 35 transmits the lock setting release signal to the mobile terminal 10 through the server transmitter / receiver 31. On the other hand, if there is a mismatch, the server control unit 35 transmits the warning message output signal through the server transmission and reception unit 31.

When the mobile terminal 10 receives the lock setting release signal from the server transmitter / receiver 31, the mobile terminal 10 releases the lock setting, and when the mobile terminal 10 receives the warning message output signal, it outputs a warning message. Thereafter, the gesture authentication process may be repeated by detecting the movement of the mobile terminal 10.

Geomagnetic sensor is a sensor that can detect the direction of the compass like a compass by grasping the flow of magnetic field in the earth. Geomagnetism is the magnetism of the earth, which is not immutable but changes periodically or irregularly. Three independent components are needed to determine the geomagnetic field at a point, and the horizontal component, azimuth and dip are included. The geomagnetic field is determined by the geomagnetic sensor by using the X-axis (horizontal) sensor, the Y-axis (vertical) sensor, and the Z-axis (up-down) sensor. That is, the X-axis sensor and the Y-axis sensor of the portable terminal 10 The left and right directions are sensed and the Z-axis sensor measures the up and down directions of the mobile terminal 10 to measure the movement direction of the mobile terminal 10.

The acceleration sensor is a sensor that can directly detect the dynamic vibration change (acceleration) of a sensor body that specifies a physical quantity called a change in speed. There is a piezoelectric acceleration sensor, and the silicon structure of the sensor changes according to the acceleration change due to the movement of the moving body, and the change in the silicon structure generates charge in the silicon. The charge generated in the silicon changes the capacitance of the sensor, which converts the amount of change of capacitance into a corresponding voltage value, and acts as a principle of detecting the movement of the moving object.

The gyro sensor is a sensor that senses this vertical force on the same principle as the acceleration sensor when the Coriolis force is generated in the vertical direction of the rotation angle by the rotation angle acceleration sensor. In addition, the altimeter is a sensor for measuring the pressure difference (pressure) that changes according to the altitude, the timer detects the start time and the completion time of the movement of the mobile terminal 10.

Using such a sensor, the sensing unit 13 detects a moving direction, a movement, a time, and the like of the mobile terminal 10.

The sensor for recognizing a fingerprint may be, for example, an optical fingerprint sensor or a semiconductor fingerprint sensor. The optical fingerprint sensor shoots strong light on the platen and reflects the shape of the fingertip on the platen, and the image of the reflected fingerprint is passed through the high refractive lens and input to the charge coupled device (CCD).

Subsequently, the portable terminal 10 transmits the user authentication setting information and the gesture setting information generated in step S41 to the authentication server 30 (S43).

Meanwhile, the process of generating user authentication setting information and the process of generating gesture setting information are equivalent processes, and the order thereof may be changed. That is, the steps S411 to S417 may be reversed from the steps S419 to S427.

The authentication server 30 stores the user authentication setting information and the gesture setting information received in step S43 (S45).

In addition, the authentication server 30 may recognize and store terminal identification information such as MIN and ESN of the mobile terminal 10 that transmits user authentication setting information and gesture setting information (S45).

Subsequently, when the user wants to cancel the lock setting set in the mobile terminal 10 or a specific menu in the mobile terminal 10, the mobile terminal 10 enters user authentication data such as, for example, 'Enter a password'. The message is output (S47).

The portable terminal 10 receives a plurality of character strings or user authentication data such as voice, biometric image, and fingerprint for unlocking the lock of the portable terminal 10 from the user (S97), and generates user authentication input information. (S99).

The portable terminal 10 generating the user authentication input information in step S99 compares the user authentication input information with the user authentication setting information, and determines whether or not it matches (S101).

If it is determined in step S101 that there is a mismatch, the mobile terminal 10 outputs a warning message (S103).

For this purpose, the warning message may be further stored in the corresponding mobile terminal 10, and may be output with reference to the warning message stored therein.

At this time, the mobile terminal 10 may display a warning message with the phrase 'password authentication failed.'

Thereafter, the process may branch to the step S95 and repeat the steps S95 to S101 to perform the authentication process based on the user authentication information.

If it is determined in step S101 that the match, the mobile terminal 10 outputs a gesture input guide message (S105).

The portable terminal 10 detects the movement of the portable terminal 10 when the user takes an action such as shaking or circular motion by holding the portable terminal 10 (S107).

If the mobile terminal 10 does not detect the movement of the mobile terminal 10 for a predetermined time, the mobile terminal 10 generates gesture input information (S109).

In operation S109, the mobile terminal 10 generating the gesture input information compares the gesture input information with the gesture setting information to determine whether the mobile terminal 10 is matched (S111).

If it is determined in step S111 that there is a mismatch, the mobile terminal 10 outputs a warning message (S113).

At this time, the mobile terminal 10 may display a warning message with the phrase 'the gesture authentication failed.'

Thereafter, the process proceeds to step S105 and the step S105 to step S111 may be repeated to perform the gesture authentication process.

If it is determined in the step (S111), the mobile terminal 10 releases the lock (S115).

In this case, a message such as 'successful authentication' or a sound or vibration may be displayed so that the user can recognize the same. By executing a specific menu immediately, the user may recognize that the lock setting of the mobile terminal 10 has been terminated.

The above description according to the second embodiment of the present invention relates to a process of confirming conformity and performing a gesture authentication process after performing an authentication process based on user authentication information, or an authentication process and gesture using user authentication information. The certification process is an equivalent process and can be changed in any order. That is, the order of steps S95 to S103 and steps S105 to S113 may be changed.

In addition, it is obvious that the mobile terminal 10 receives the user authentication input information and the gesture input information together and performs the authentication process together, and the process of releasing the lock setting of the mobile terminal 10 is also included in the present invention.

The mobile terminal 10 transmits the gesture input information generated in step S143 to the authentication server 30 (S145).

The authentication server 30 that has received the gesture input information in step S145 compares the gesture input information with the gesture setting information and determines whether they match (S147).

In this case, the authentication server 30 may determine that the gesture input information corresponds to each other if the gesture input information is included in the error range for each element of the gesture setting information indicating the movement of the terminal, such as a preset movement speed, a position coordinate, and a radius of the movement trajectory. (S147).

In addition, the authentication server 30 searches for terminal identification information stored together with the gesture setting information by referring to terminal identification information of the mobile terminal 10 that has transmitted the gesture input information, and then finds corresponding terminal identification information to find the gesture input information. It may be determined whether or not the match by comparing the gesture setting information with (S147).

If it is determined in step S147 that there is a mismatch, the authentication server 30 transmits a mismatch signal to the mobile terminal 10 (S149).

If it is determined in step S147 that the match, the authentication server 30 transmits a confirmation signal to the mobile terminal 10 (S151).

The portable terminal 10 determines which signal is a received signal (S153), and outputs a warning message when receiving a mismatch signal (S155).

At this time, the mobile terminal 10 may display a warning message with the phrase 'the gesture authentication failed.'

Thereafter, the process proceeds to step S139 and the gesture authentication process may be performed by repeating steps S139 to S153.

The portable terminal 10 determines what signal the received signal is (S153), and upon receiving the confirmation signal, releases the lock setting of the portable terminal 10 (S157).

In this case, a message such as 'successful authentication' or a sound or vibration may be displayed so that the user can recognize the same. By executing a specific menu immediately, the user may recognize that the lock setting of the mobile terminal 10 has been terminated.
