More specifically, the controller may be configured such that the arbitrary characters are variably displayed only when it is detected that the user contact starts at an arbitrary point of the variable pattern and moves along the variable pattern while the contact is maintained. Characterized in that.

More specifically, the arbitrary characters are variably displayed based on at least one of a moving direction and a moving speed of a user contact moving along the variable pattern, and the controller is configured to perform the arbitrary character based on the moving direction of the user contact. Characters of the variable is to be displayed variable according to a specific arrangement order, based on the moving speed of the user contact is characterized in that the speed at which the arbitrary character is displayed variable.

More specifically, the determination of whether the variable displayed character matches the preset character is performed when a user contact moving along the variable pattern is released or when movement of the variable pattern is stopped at a specific point of the variable pattern. The control unit may determine whether or not the specific character displayed on the display is matched with the preset character when the user contact is released or the movement is stopped.

More specifically, the controller, if it is detected that the user contact is started at any point of the variable pattern, and released after the contact is maintained at the arbitrary point, the arbitrary character and the predetermined character match It is characterized by determining whether or not.

More specifically, the entire character string is characterized in that the number of characters arranged every time the lock function is released.

More specifically, the variable pattern, characterized in that at least one of the shape and size of the pattern is displayed differently each time the lock function is released.

In accordance with a second aspect of the present invention, there is provided a method of operating a terminal device that supports a locking function, wherein each character of the entire character string and a variable pattern for varying the arbitrary character are changed whenever the locking function is released. A display step of displaying; And when a user contact moving along the variable pattern is detected, the random characters are variably displayed as characters other than the random characters of the entire string based on the detected user contact, and the variable displayed characters If it is determined that matches the predetermined character, characterized in that it comprises a control step for releasing the lock function.

More specifically, the control step, the arbitrary character is variable display only when it is detected that the user contact is started at any point of the variable pattern, and moving along the variable pattern while the contact is maintained. It is characterized by that.

Characters of the variable is to be displayed variable according to a specific arrangement order, based on the moving speed of the user contact is characterized in that the speed at which the arbitrary character is displayed variable.

More specifically, the determination of whether the variable displayed character matches the preset character is performed when a user contact moving along the variable pattern is released or when movement of the variable pattern is stopped at a specific point of the variable pattern. The control step may include determining whether or not the specific character displayed and the preset character match when the user contact is released or movement is stopped.

More specifically, the control step, if it is detected that the user contact is initiated at any point of the variable pattern, and released after the contact is maintained at any point, the arbitrary character and the predetermined character is It is characterized by determining whether or not.

More specifically, the method may further include an authentication step of performing user authentication based on a fingerprint of the user before the displaying step, wherein the displaying step is performed when the user authentication is completed in the authentication step. Only the arbitrary characters and the variable pattern are displayed.

Therefore, according to the unlocking method of the present invention and the apparatus applied thereto, when a character of the entire string is displayed every time the locking function of the terminal device is released, the user converts the arbitrary character to the remaining characters of the entire string. By implementing the variable to release the lock function, it is possible to greatly improve the convenience and security associated with the lock function.

2 to 4 are views for explaining the screen of the terminal device according to an embodiment of the present invention.

5 is a view for explaining an authentication procedure according to another embodiment of the present invention.

6 is a view for explaining a service screen according to another embodiment of the present invention.

7 is a view for explaining the operation flow in the terminal device according to an embodiment of the present invention.

An operation characteristic of the terminal device for releasing such a lock function will be described below.

The display unit 100 performs a function of displaying an arbitrary character and a variable pattern.

More specifically, in the state in which the lock function of the terminal device is activated, the display unit 100 detects a user contact made on the screen through the sensing unit 300, and varies random characters and the random characters among all designated character strings. The variable pattern for display is displayed.

Here, the entire character string refers to a set of numbers, Korean characters (for example, Choseong), English letters (for example, alphabet), etc. having a specified arrangement order, and the random characters are randomly selected from the entire string. Say the character.

For example, when the entire string is a set of numbers having a consecutive sequence of '0' to '59', the arbitrary characters may be '0', such as '15', '17', '35', etc. It may correspond to a randomly selected number from consecutive numbers from '59'.

As another example, when the entire string is a set of alphabetic characters having a sequence of sequences from 'A' to 'Z', the arbitrary characters may be 'A' such as 'C', 'D', 'M', etc. To 'Z' may correspond to a randomly selected English letter.

On the other hand, in the above as an entire string according to an embodiment of the present invention, the number and the alphabetic characters having a continuous array order is given as an example, the sequence of the entire string does not necessarily have a continuous sequence, according to the specification Various orderings can be applied.

As such, the entire string may be formed of various combinations such as, for example, numbers, Korean, and English characters. Hereinafter, for convenience of description, the entire string will be described on the premise that the entire string is composed of a set of numbers having a continuous sequence. do.

In addition, the variable pattern is a UI (User Interface) displayed on the screen as a means for varying the arbitrary number, for example, the shape and size of the circle, bar type, etc. are not limited, but the following description is for convenience. For the sake of brevity, a circle formed to surround any character displayed on the screen will be described as an example.

As a result, as shown in FIG. 2, the display unit 100 simultaneously generates three numbers '35', '34', and '20' as arbitrary characters and sequentially ((a)-> (b)-> ( c)), and the circular variable pattern formed to surround the number can be displayed with each number.

In this case, the display method of three numbers generated as arbitrary characters may be a sequential display method in which numbers in the next order are displayed when authentication for each number is completed.

In addition, the three numbers generated as random characters may be generated collectively at the same time point as described above, or may be generated by generating a number in the following order when authentication is completed after generating the first one number. There will be.

In this case, the display of three numbers as random characters is based on the premise that three numbers are set as passwords in connection with the lock function. Only one variable number of circular patterns formed to enclose a number may be displayed.

Of course, even if there is more than one password, it is possible to generate and display a random character only once at the beginning, and the remaining passwords may be authenticated in the same pattern.

On the other hand, the display unit 100 is displayed on the screen any character different from the time when the attempt to release the previous funds in order to enhance the security, each time the attempt to unlock the lock function, and the display of all characters containing the random characters The range (eg 0 ~ 59, 0 ~ 75, ..., 0 ~ 100) can also be displayed in various ways.

Here, the attempt to release the lock function may be performed after the lock function is released again at a specific time or when the lock function is activated again, or when the lock function of the terminal device fails to release (for example, a password re-entry). .

In addition, the shape and size of the variable pattern may be changed whenever an attempt is made to release the lock function.

For example, the variable pattern may be changed through a variety of ways such that the shape is changed from circular to bar shape or vice versa from bar shape to circular shape, or only the size of the sieve pattern is maintained. Can be.

Of course, in the case of the variable pattern, not only the above-described method that is changed randomly every time the lock function is released, but also a method in which a fixed shape and size are maintained according to a user specification.

The control unit 200 performs a function to variably display any character displayed on the screen.

More specifically, the controller 200 is based on the detected user contact, if a user letter moving along the variable pattern is detected by the sensing unit 300 in the state in which a random letter and the variable pattern is displayed on the screen. The display unit 100 causes the arbitrary characters being displayed to be variably displayed in other characters according to the arrangement order of the entire character string.

In this case, the control unit 200 may start at an arbitrary point of the variable pattern, and the display unit 100 may be used only when the sensing unit 300 detects that the user contact is moved along the variable pattern while the contact is maintained. ) Causes variable characters to be displayed randomly on the screen.

Here, any character displayed on the screen may be variably displayed according to the moving direction of the user contact moving along the variable pattern.

Accordingly, the controller 200 may variably display the arbitrary characters in descending or ascending order, for example, along the moving direction of the user contact moving along the variable pattern.

For example, referring to FIG. 3A, it may be assumed that the number '35' is displayed on the screen as an arbitrary character.

In this case, the control unit 200 starts at 12 o'clock of the variable pattern surrounding the number '35', and when it is detected that the user moves in the counterclockwise direction (①-> ②), as an arbitrary character. The displayed number '35' is variablely displayed as '34', '33', '32', ..., '20' in descending order according to the arrangement order.

On the contrary, when it is detected that the user contact moves in the clockwise direction (①-> ③), the controller 200 determines that the number '35' displayed as an arbitrary character is '36', '37', '38' in ascending order. , ... '45' can be displayed as variable.

Here, the point of the variable pattern at which the user contact is started is not limited to the '12 o 'direction as in the above example, and may be started at any point of the variable pattern desired by the user.

For example, referring to FIG. 3 (a), it may be assumed that a number '35' is displayed as an arbitrary character and the number '20' is set as a password.

At this time, if the starting point of the user contact is 12 o'clock (①), the movement path of the user contact should move counterclockwise to the 9 o'clock (②), and the starting point of the user contact is the 4 o'clock (④). ), The movement path of the user's contact moves to the 9 o'clock (②) through 12 o'clock (①) in the counterclockwise direction, or to the 9 o'clock (②) through the 6 o'clock clockwise direction. do.

In this way, the user contact made on the variable pattern can be seen that the starting point is different depending on the user's will.

This means that the movement path of the user's contact is changed every time on the screen, so that even if a mark remains due to the movement of the user's contact on the screen, it will be impossible for others to guess the set password.

In addition, as mentioned above, any character displayed on the screen is displayed differently every time the lock function is released. This also means that the movement path of the user contact on the screen is different every time the lock function is released.

For example, referring to FIG. 3, when the initial lock function is released (a), the number '35' is displayed as an arbitrary character, and when the lock function is released (b), the number 'changed from the number' 35 'is displayed. 15 'is displayed, the number' 20 'is set as a password, and the starting point of the user contact is the same at 12 o'clock.

At this time, when the initial lock function is released (a), in order to change the number '35' to the password '20', the user contact must move to the left side starting at 12 o'clock, and then when the lock function is released (b) Contrary to the above, it can be seen that the user's contact must move to the right, starting at 12 o'clock, and the moving distance is also different from each other.

As a result, if any character displayed on the screen changes every time the lock function is released, the direction and distance to which the user's contact should move may be different. This is based on the marks on the screen resulting from the movement of the user's contact and guesses the password of another person. You can block what you do.

Meanwhile, any variable displayed on the screen may vary according to the moving speed of the user contact moving along the variable pattern.

That is, the control unit 200 causes the arbitrary characters displayed on the screen to be changed rapidly according to the arrangement order as the moving speed of the user contact is faster, and conversely, if the moving speed of the user contacts is slow, the arbitrary characters displayed on the screen. Can be changed slowly.

This is to take into account the difference between the numbers displayed as random characters on the screen and the set sequence of the set password.

For example, in the case of a large difference in the arrangement order between a number displayed as an arbitrary character and a set password, even if the moving speed of a user contact is fast even with the same moving distance, the number displayed as an arbitrary character is reversed. By changing more quickly than the case, it is possible to enable quick access to the password.

On the contrary, in the case where the difference in the sequence of order between the number displayed as an arbitrary character and the set password is small, when the moving speed of the user's contact is slow even with the same moving distance, the number displayed as the arbitrary character is reversed. By allowing it to change more slowly, it allows for precise access to passwords.

In addition, the controller 200 performs a function of releasing the locking function of the terminal device.

More specifically, when it is determined that the variable variable characters match the preset characters by the user's contact, the control unit 200 releases the lock function of the terminal device.

At this time, the controller 200 determines the number displayed on the screen as a character input by the user at the time when it is detected that the user contact moving along the variable pattern is released. This will unlock the device.

For example, referring to FIG. 4, three numbers of '35', '34', and '20' are displayed as random characters, and '20', '45' and '55' are respectively represented as a password. It can be assumed if it is set.

In this case, the control unit 200 is in a state in which the number '35' is variably displayed as '20' according to the user's contact moving along the variable pattern surrounding the number '35', and the user's contact is released from the variable pattern or at a specific point. In the case of staying for a certain time, the number '20' is determined by the password entered by the user.

At this time, since the control unit 200 is the number '20' and the password '20' input by the user is matched, and receives the numbers in the same manner as described above for the following random characters '34', '20', respectively, If all the numbers match the respective passwords, the terminal device unlocks the lock function.

For reference, the numeric input of the user is not only when the user's contact is released from the variable pattern or stays at a specific point of the variable pattern for a certain time as in the above example, for example, after the user's contact moves into the variable pattern or after the user's contact is released. This may also be done when tapping the screen.

In this regard, when a user inputs a number, the input number may blink or a vibration may be generated so that the user may recognize that the number has been input.

For reference, when generating and displaying a random character only once initially, the control unit 200 receives the number '20' as the number input by the user and immediately inputs the remaining password in the same manner on the same pattern. When the numbers all match each password, the terminal device unlocks the lock function.

Meanwhile, in one embodiment of the present invention, a method of releasing the locking function of the terminal device by using a variable pattern is specified. However, security can be enhanced by adding a separate authentication function as follows.

For example, as shown in FIG. 5, before the lock function using the variable pattern is released, the terminal device first performs fingerprint recognition, and only when the executed fingerprint recognition is successful, the variable pattern is used. Authentication can be performed in addition, in this case, it can be expected to greatly improve the security than the authentication method using only one variable pattern.

 Of course, the iris recognition may be performed instead of the fingerprint recognition applied in the above example, or it may be possible to additionally perform the iris recognition together with the authentication using the fingerprint recognition and the variable pattern.

In addition, in the embodiment of the present invention, if the lock function of the terminal device is released using the variable pattern, an additional service scheme utilizing the variable pattern being displayed may be possible.

For example, as shown in FIG. 6, when the unlocking function of the terminal device using the variable pattern is completed, only the variable pattern is displayed on the screen, and the execution icons of the application or the specific function are arranged along the variable pattern. If you choose to do this, you can enable the rapid execution of applications or specific functions.

In this case, the application or the specific function disposed on the variable pattern may be an application or a specific function executed by the user immediately before activating the unlocking function, or an application or a specific function registered in the user.

As described above, according to the terminal device according to an embodiment of the present invention, whenever a character of the entire text string is displayed every time the lock function of the terminal device is released, the user displays the arbitrary text among the entire text string. By implementing the variable to be the remaining characters to release the lock function, it is possible to greatly improve the convenience and security associated with the lock function.

Hereinafter, a method of operating a terminal device according to an embodiment of the present invention will be described with reference to FIG. 7.

Here, for the convenience of description, the configuration shown in FIGS. 1 to 4 described above will be described with reference to the corresponding reference numerals.

First, when the user's touch on the screen is detected through the sensing unit 300 while the locking function of the terminal device is activated, the display unit 100 may change an arbitrary character of the designated character string and the arbitrary character. The variable pattern is displayed (S110-S120).

In this case, as shown in FIG. 2, the display unit 100 may include '35', '34', as an arbitrary character in the entire string that is a set of numbers having a continuous sequence of '0' to '59'. '20' Three numbers are generated simultaneously and displayed sequentially ((a)-> (b)-> (c)), and a circular variable pattern configured to surround the numbers can be displayed with each number. have.

In this case, the display method of three numbers generated as arbitrary characters may be a sequential display method in which numbers in the next order are displayed when authentication for each number is completed.

In addition, the three numbers generated as random characters may be generated collectively at the same time point as described above, or may be generated by generating a number in the following order when authentication is completed after generating the first one number. There will be.

Then, when a character and a variable pattern are displayed on the screen and the user contact moving along the variable pattern is detected through the sensing unit 300, the controller 200 displays the display unit based on the detected user contact. In operation S130-S140, the character 100 is variably displayed as another character according to the arrangement order of the entire character string.

In this case, the control unit 200 may start at an arbitrary point of the variable pattern, and the display unit 100 may be used only when the sensing unit 300 detects that the user contact is moved along the variable pattern while the contact is maintained. ) Causes variable characters to be displayed randomly on the screen.

For example, referring to FIG. 3A, when the number '35' is displayed on the screen as an arbitrary character, the controller 200 starts at 12 o'clock of the variable pattern in which the user's contact surrounds the number '35'. When it is detected to move in the counterclockwise direction (①-> ②), the number '35' displayed as an arbitrary character is '34', '33', '32', ... To be displayed as '20'.

On the contrary, if it is detected that the user contact moves in the clockwise direction (①-> ③), the control unit 200 displays the numbers '35' displayed as arbitrary letters in the ascending order of '36', '37', '38'. Variable display of ', ...' 45 '

Here, the point of the variable pattern at which the user contact is started is not limited to the '12 o 'direction as in the above example, and may be started at any point of the variable pattern desired by the user.

For example, referring to FIG. 3 (a), it may be assumed that a number '35' is displayed as an arbitrary character and the number '20' is set as a password.

At this time, if the starting point of the user contact is 12 o'clock (①), the movement path of the user contact should move counterclockwise to the 9 o'clock (②), and the starting point of the user contact is the 4 o'clock (④). ), The movement path of the user's contact moves to the 9 o'clock (②) through the 12 o'clock direction (①) in the counterclockwise direction, or to the 9 o'clock (②) through the 6 o'clock direction in the clockwise direction. do.

Subsequently, when it is determined that the variable variable characters match the preset character by the user's contact, the controller 200 causes the locking function of the terminal device to be released (S150-S180).

At this time, the controller 200 determines the number displayed on the screen as a character input by the user at the time when it is detected that the user contact moving along the variable pattern is released. This will unlock the device.

For example, referring to FIG. 4, the controller 200 displays three numbers, '35', '34', and '20', respectively, as random characters, and '20', '45', When '55' is set respectively, the user's contact is released from the variable pattern or the specific point is released while the number '35' is variably displayed as '20' according to the user's contact moving along the variable pattern surrounding the number '35'. In the case of staying for a certain time, the number '20' is determined by the password entered by the user.

At this time, since the control unit 200 is the number '20' and the password '20' input by the user is matched, and receives the numbers in the same manner as described above for the following random characters '34', '20', respectively, If all the numbers match the respective passwords, the terminal device unlocks the lock function.

As described above, according to the operating method of the terminal device according to an embodiment of the present invention, each time the user unlocks the arbitrary character in a state in which any character of the entire string is displayed every time the lock function of the terminal device is released. By implementing the variable to be able to change to the remaining characters of the entire string to release the lock function, it is possible to greatly improve the convenience and security associated with the lock function.
