As shown in FIG. 1, the user device 100 can be implemented to be used after releasing the lock state through authentication. The user device 100 can perform the identity authentication by receiving the position and the stopping time of the user's eyes 200. [ That is to say, the user has to set the position of the pupil 200 to gaze at the cryptographic component 120 in a predetermined order in order to unlock the user device 100 and the position of the pupil 200 gazing at each cryptographic component 120 The pause time is input, and the user device 100 can analyze this to determine whether to release the lock state.

According to the embodiment of the present invention, the user device 100 compares the order and stop time of the moving direction of the pupil 200 with the order and stop time of the moving direction of the predetermined pupil to be unlocked to be unlocked, It may be determined whether to release the locked state of the device 100. The order of the moving directions of the predetermined pupil may be the order of the directions of the pupils moving according to the order of the characters or graphics and may be a sequence of directions of the pupils moving sequentially in a specific area of the screen It is possible.

The stopping time of the pupil 200 may mean the time of the gaze which lasts without changing the gaze area including the specific position after the gaze is started by moving the specific position. That is, the point at which the pupil 200 gazes may be changed within the same area.

As shown, the user device 100 includes a camera unit 130. [ The camera unit 130 collects image information from the outside. The camera unit 130 may collect eye movement information of the user and image information for the face recognition of the user.

The display 105 of the user device 100 may display a screen required for driving and using the user device 100. [

The display 105 may be displayed with a cryptographic component 120 for releasing it from the locked state. The password component 120 may be composed of image symbols (symbols, pictures, figures, numbers, letters, symbols, etc.) used for password setting. The cryptographic components 120 may be arranged in a fixed position and may be arranged at different positions randomly in the lock screen. Further, symbols, photographs, figures, numbers, letters, and symbols used as image symbols may be used in combination of a plurality of formats.

The password input screen 110 may be displayed on the display 105. [ The password may be set in the input order of the cryptographic component 120 or the movement pattern of the pupil, and may include the pause time of the pupil 200. If the password is set to include the input order and the pause time of the password component 120, the input order of the password component 120 input by the pupil 200 and the stopping stare of each password component 120 If the time matches the preset input sequence and time, the lock is released. When the password is set as the movement pattern and the stop time of the pupil 200, the lock is released if the movement pattern and the stop time of the pupil 200 coincide with the preset order and time.

The password component 120 that is input for security may not display the specific content input on the password input screen 110 or may display the content of the last entered password component 120 on the password input screen 110 for a certain time After the display, the input content may be set not to be displayed after a predetermined time has elapsed.

Vibration, light, sound, etc. may be used as feedback to the input. Feedback to the input may not be used depending on the settings.

In the embodiment of FIG. 1, when the password for unlocking is 3457, the user can sequentially take the numbers 3, 4, 5, and 7 in the order of the passwords to release the lock. At this time, the user's eyes move in the order of upper left, lower right, left, and upper right starting from the central area. The camera unit 130 may collect the user's eye movement information and release the lock if the collected eye movement information of the user matches the predetermined order to unlock the user apparatus 100. [

The cryptographic component 120 may be arranged in any order whenever the lock screen is displayed. That is, when the password for unlocking is 3457, since the position of each digit is changed, the user's pupil movement information necessary for unlocking can be changed correspondingly.

At this time, the password for unlocking may include time information in which the pupil 200 stops and the gaze continues, in addition to the order in which the cryptographic component 120 is selected by the input.

Hereinafter, a method for determining whether the user apparatus 100 receives the pupil movement information and analyzes the received pupil movement information to release the lock setting of the user device 100 will be described in detail. do.

FIG. 2 is a conceptual view illustrating a pupil photographing screen of a user to which an XY coordinate system is applied according to an embodiment of the present invention, and FIG. 3 is a conceptual diagram illustrating a pupil descriptor for detecting a pupil position according to an embodiment of the present invention. An XY coordinate system may be applied to the photographing screen on which the user's pupils are photographed through the camera unit 130. [ In the XY coordinate system, the origin may be the center of the display 105 and may be a predetermined point of the display 105 according to the user's selection.

As shown in FIG. 2, when the XY coordinate system is applied to the photographing screen, the coordinates of the point where the user's pupil 200 is located are calculated centering on the origin of the XY coordinate system. In order to calculate the coordinates, the X-axis and the Y-axis may have coordinate values at regular intervals. For example, the user's pupil 200 may have an X-axis coordinate value (x1) of -4 and a Y-axis coordinate value (y1) of 4. In this case, the coordinate value of the point where the user's pupil 200 is located can be calculated as (-4,4).

It is possible to determine whether the user's pupils 200 are located in nine areas (for example, R1 to R9 divided into nine) on the display 105 by using the coordinate values of the positions at which the user's pupil 200 is located have.

Specifically, when the X-axis coordinate value (x1) of the pupil 200 position is less than -3, it can be determined that the position of the user's pupil 200 is divided into three by the X-axis and leftward, It can be determined that the center is on the X axis, and if it is 3 or more, it can be determined that the X axis is on the right side. If the Y axis coordinate value (y1) of the pupil 200 position is less than -3, it can be determined that the pupil 200 position of the user is located at the lower position with respect to the Y axis. If the coordinate position is less than -3 and less than 3, It can be determined that it is the center, and when it is 3 or more, it can be judged that the upper end is based on the Y-axis.

This may be set differently depending on the number of divisions of the area and the size of the display 105, for example.

As described above, according to the determination result of the X-axis coordinate value and the Y-axis coordinate value of the position of the pupil 200, when the user's pupils 200 are displayed in nine regions (R1 to R9 divided into nine) Can be determined. 1, when the password is 3457, the lock is released only when the pupil 200 of the user is moved in the order of R1, R9, R7, and R3. When the password is 3457 and the position of each digit is changed, the position of the pupil 200 for unlocking is changed corresponding to the order of the area corresponding to the changed position of 3, 4, 5,

(R5, R9, R7, R3), (R1, R5, R5, R6) in addition to the order of R1, R9, R7 and R3 when the user's pupil movement information necessary for unlocking, R4, R2), (R5, R9, R8, R6), and so on. In order to prevent this, if the lock is released by the user's pupil movement information regardless of the password, the movement length and position of the pupil 200 may be simultaneously considered in addition to the movement direction of the user's pupil movement information.

Further, in order to release the locking state of the user device based on the position and the stopping time of the pupil 200, an input that lasts more than a predetermined time is required for the same area. In response to this, a loading bar 180 indicating the stopping time of the pupil 200 may be displayed when the user's pupil 200 is looking at a specific region.

The loading bar 180 may indicate the stopping time of the pupil 200 in steps. In other words, when the examination time recognized as an input is set to be divided into three levels, the first region 181, the second region 182, and the third region 183 can be distinguished and the pupil 200 is stopped The input may be changed from the first region 181 to the third region 183 as the time for the gazing becomes longer. The loading bar 180 may be displayed on a portion of the display 105, or on the entire display 105, corresponding to the position of the user's pupil 200. [

Since the input step of the time according to the gazing time is distinguished in the input process and must be recognized by the user, when the loading bar 180 is not displayed, the input step of the time according to the gazing time is performed using the color change or vibration of the display 105 Can be displayed. For example, the backdrop of the display 105 may display a blue color representing the entry time of the first step, a red color representing the input of the entry time of the second step, and an entry entry time of the third entry, White, and may be repeatedly displayed in the order of the first step, the second step, and the third step with the lapse of time.

When the user intends to input the second inputting time of the second step, the user moves the line of sight to the password of the next cipher component when the display 105 is red or shakes or tilts the user device 100, The input of the gazing time of the pupil 200 can be determined, and when the gaze time input of the pupil 200 is determined, the user can be informed of the vibration, light, sound, or the like by feedback thereof.

4 is a conceptual diagram showing a user apparatus according to an embodiment of the present invention. 4, the user device 100 includes a camera unit 130, a pupil position measurement unit 140, a pupil input time measurement unit 145, a storage unit 150, a user setting unit 160, 170).

The camera unit 130 can photograph and collect an external image, and can recognize the pupil 200. The camera unit 130 may photograph the user's face to photograph the user's eyes 200. [ When the user uses the user device 100, the user device 100 faces the user device 100 at a position close to the user's face. Thus, the camera unit 130 can photograph the user around the user's eyes. The camera unit 130 continuously captures the user for real-time tracking of the pupil 200 position.

In addition, the camera unit 130 can recognize the user's face. Accordingly, even if the password is known, since the lock can not be canceled if the user authentication through the face recognition is not completed, the security can be improved by releasing the lock by interlocking the face recognition of the user.

The pupil position measurement unit 140 measures the position of the user's pupils 200 necessary to release the lock and converts the measured data into data.

The pupil position measuring unit 140 calculates the position of the geometric pupil from the camera unit 130 using angles in both eye directions and distances between both eyes. The pupil position measurement unit 140 outputs pupil position data for the calculated actual geometric eye position.

The pupil position measurement unit 140 sets a predetermined reference point on the photographing screen including the user's pupil photographed from the camera unit 130 as the origin and sets the center point position of the photographed user's pupil 200 as the origin , The X-axis coordinate value and Y-axis coordinate value of the pupil are calculated based on the origin.

The origin may be a center of the pupil 200 when the user gazes at a specific point on the display 105, and the specific point may be the center of the display 105. Specifically, a reference point can be set by the user gazing at a specific area displayed in the central area of the display 105 for a predetermined time on the initial screen for unlocking, and the X-axis coordinate value of the pupil 200 And Y-axis coordinate values, and measures the position of the pupil 200. [ The reference point may be used by the user to set it at an initial time, and may be changed as needed.

The pupil input time measuring unit 145 measures the input time of the pupil 200. That is, the duration of the stationary state after the movement of the pupil 200 is measured, and the input time zone of the pupil is determined in the time zones classified by stages.

The storage unit 150 may store a password set by the user setting unit 160. The control unit 170 may include a camera unit 130, a pupil position measurement unit 140, a pupil input time measurement unit 145, And may be implemented to control the operation of the storage unit 150 and the user setting unit 160.

If the information about the position and the stop time of the input pupil is released from the locked state of the user device 100 as a result of the analysis of the pupil position measurement, the controller 170 cancels the locked state of the user device 100 . ≪ / RTI > On the contrary, if the information about the position and the stop time of the input pupil is not released from the locked state of the user device 100 as a result of the analysis of the pupil position measurement, the control unit 170 does not release the locked state of the user device 100 And to re-enter information about the user's pupil position and pause time.

5 is a flowchart illustrating a method of unlocking a user device based on a pupil position and a stop time according to an embodiment of the present invention.

As shown in FIG. 1, the user device 100 displays the cryptographic component 120 on the display 105 to unlock (SlOO). The password component 120 is an image symbol used for password setting, and may be a symbol, a photograph, a graphic, a number, a character, a symbol, or the like, or may be displayed by a combination thereof.

The cryptographic components 120 may be arranged in a sequential order on the display 105 and arranged in any order. For example, they may be displayed in the order of starting from the upper left corner of the display 105 toward the lower right corner, or in any order as in Fig. The movement information of the user's pupils 200 necessary for unlocking can also be correspondingly changed in accordance with the arrangement order of the cryptographic components 120 displayed on the display 105. [

Next, the camera unit 130 acquires position information of the pupil 200, and the pupil input time measurement unit 145 measures the pupil 200 input time (S200). The step of collecting the position information of the pupil 200 includes the steps of applying an XY coordinate system to the photographing screen by setting a predetermined reference point as the origin, calculating X-axis coordinate values and Y-axis coordinate values of the pupil 200 position .

Next, the position information of the pupil 200 collected by the camera unit 130 is compared with the position and the stop time of the pupil necessary for unlocking, and it is determined whether or not the position matches the password (S300). Then, (S400). Determining whether or not to release the lock state may further comprise a face recognition authentication procedure of the user in addition to the information related to the position of the pupil.

The password may be set to the input order of the cryptographic component or the movement pattern of the pupil. When the password is set in the input order of the cryptographic component, the lock is released when the input order of the cryptographic component 120 input by the pupil 200 matches a predetermined order. When the password is set to the pupil's movement pattern, the lock is released if the pupil's movement pattern coincides with the preset order.

In addition, if the position information of the pupil 200 is compared with the position and the stop time of the pupil necessary for unlocking and the password does not coincide with the password, the locking state of the user device 100 may not be released and the determination step may be terminated.

6 is a conceptual diagram illustrating an authentication method based on a pupil position and a stop time according to another embodiment of the present invention. The cryptographic component 120 displayed on the display 105 can be set to a plurality. I.e., the first cryptographic component 120-1, the second cryptographic component 120-2, and the third cryptographic component 120-3. Each cryptographic component may be set to a different password. For example, the password of the first cryptographic component 120-1 may be set to 1674, the password of the second cryptographic component 120-2 may be set to 8194, the third cryptographic component 120 -3) can be set to the right, the left, the left, and the right with the movement of the pupil based on the graphic of the star whose movement pattern of the pupil is centered. Each password may include the pause time of the pupil 200, in addition to the input order of the cryptographic component 120 or the movement pattern of the pupil.

The first cryptographic component 120-1, the second cryptographic component 120-2, and the third cryptographic component 120-3 may be distinguished by the color, page display, etc. of the display 105. For example, if the display 105 is blue, it can be unlocked by entering a password for the first cryptographic component 120-1, and if the display 105 is red, the second cryptographic component 120 -2), and can be unlocked by entering the password of the third cryptographic component 120-3 if the display 105 is yellow.

If the display 105 is blue, the password of the first cryptographic component 120-1 is 1674, so that the user can release the lock by moving the pupil 200 in order of 1674. [ In the drawing, the first cryptographic component 120-1 is displayed sequentially, but may be displayed in any order like the second cryptographic component 120-2. Even in this case, the user can enter the password 1674 of the first cryptographic component 120-1 to release the lock.

If the display 105 is red, the password of the second cryptographic component 120-2 is 8194, so that the user can release the lock by moving the pupil 200 in the order of 8194. [

When the display 105 is yellow, the password of the third cipher component 120-3 is a right, a left, a lower, a right, a left, Can be released in the order of right, up, left, and down.

In each case, since the password includes the stopping time of the pupil 200, the color of the display 105 can be sequentially changed with time, or the input time can be confirmed by the change of vibration, brightness, and the like.

As described above, the password is set differently according to each cryptographic component, thereby improving the security.
