[Method and Device for Unlocking Input using the Combination of Alphabet and Pattern Image at Smartphone}

The present invention relates to an unlocking device and a control method thereof for making it difficult to prevent the unlocking of a smartphone from leaking, and to generate and control the unlocking by a combination of a character and a pattern input.

In recent years, due to the rapid development of communication technology, functions in mobile terminals are gradually expanding, and accordingly, more various user interfaces (UIs) and various functions using the same are provided.

In particular, a mobile terminal equipped with a touch screen has various input device locking/unlocking functions in order to limit unnecessary input errors or use by other users in a standby state. In general, the mobile terminal performs the locking function only when the user selects to activate the locking function. To this end, the user can set the lock function of the mobile terminal by selecting any one of lock methods such as a pattern, a numeric PIN, and a password.

In the case of a mobile terminal in which the locking function is set as described above, the locking function is activated when there is no input from the user for a certain period of time. Accordingly, even if the user uses a specific function of the mobile terminal and does not input for a certain period of time, the screen or function of the mobile terminal is deactivated. At this time, a typical mobile terminal releases the lock mode by inputting a password defined in advance or defined by a user's setting in order to release the lock mode, for example, a touch screen hold state.

As described above, the mobile terminal activates the locking function whenever the waiting time for waiting for a user input elapses. In addition, in recent years, bank funds are now actively traded using smartphones, such as buying stocks and buying goods.

In addition, when a user sets a complex password or pattern to reinforce the security of the mobile terminal, a lot of labor is required compared to the case of releasing the lock function using a simple password or pattern. Conversely, if a simple password or pattern is used to reduce hassle, there is a risk of exposure to third parties or theft, which may cause security problems. Accordingly, there is a need for user authentication of a mobile terminal, which is the original purpose of the locking function, which can maintain high security by preventing unwanted input errors in the mobile terminal or theft by a third party, and simple to implement the unlocking function.

Accordingly, the present invention provides a method and apparatus for more conveniently releasing the locking function of a mobile terminal.

In addition, the present invention provides a method and apparatus for authenticating a locking function of a mobile terminal by combining a character and a pattern so that a high level of security can be provided using information that a user usually knows well.

In addition, the present invention provides a method and an apparatus for a keypad for mixing characters and patterns, in which characters and patterns can be input from one keypad in order to quickly and simply input the characters and patterns.

The present invention for achieving the above is a method for unlocking a combination of a character and a pattern in a mobile terminal, the process of receiving an unlock command combining a character and a pattern from a user after setting to a lock mode, and And comparing the received lock release command with the lock release command set as a combination of and pattern, and releasing the lock mode when the comparison result matches a combination value of a character and a pattern.

According to the present invention, when a user sets an authentication password by combining 4 characters and 1 pattern, approximately 900 billion cases are generated, thus providing a much higher security than conventional input of 6 characters and numbers or patterns. Will have. On the other hand, the user does not have to memorize new password items additionally, does not forget, is familiar with, and has the advantage of simple input.

In addition, according to the present invention, since a character keypad and a pattern image keypad can be integrated into one keypad and each can be input, it is possible to input quickly and simply without the need to switch between the character keypad and the pattern keypad.

It is difficult to leak the authentication password. It is difficult for a third party who sees four characters of a password and a pattern image to be entered consecutively to remember it all and imitate it.

The authentication password input is simple and short. One character and one pattern can be entered consecutively on the same keypad.

Even when the smartphone is lost, it is difficult to understand the combination of 4 characters and patterns, so the unlock password is not leaked.

It is simply composed of four characters and familiar elements of the pattern, but the security and the number of cases are very high. About 900 billion cases occur.

The present invention provides a method of enabling a more secure and convenient unlocking of a locking function. To this end, the present invention configures the unlocking of the mobile terminal by a combination of a character and a pattern, switches the mobile terminal to a locked state, sets a lock password by combining the character and pattern, and when the unlock command is input, It is determined whether the lock release command combining the set character and pattern matches the input lock release command, and if they match, unlocking the lock. Since the combination of characters and patterns is changed to a highly secure unlocking method, there is an advantage of providing convenience of unlocking to a user and enhancing security of a mobile terminal.

Referring to FIG. 1 to examine the components of the mobile terminal implementing the above-described functions and operations thereof.

Referring to FIG. 1, a mobile terminal according to an embodiment of the present invention includes a control unit 11, a memory 12, a display unit 13, an input unit 14, and a communication unit 15. 1 shows a schematic configuration example of a mobile terminal for convenience of description. However, the mobile terminal of the present invention is not necessarily limited to the above configuration. In addition, as an example of a mobile terminal according to an embodiment of the present invention, in addition to a mobile phone capable of communication, any device requiring user lock such as a personal computer, a notebook computer, a digital sound source playback device, and a portable multimedia player (PMP) can be of course possible.

First, the memory 12 stores various data generated and utilized in the mobile terminal. Such data includes data generated according to the execution of an application by the mobile terminal, and all types of data that can be stored or generated using the mobile terminal or received from the outside. In particular, the data according to an embodiment of the present invention may include a user interface provided by the mobile terminal, various setting information according to the use of the mobile terminal, and information on a lock step setting in which a character and a pattern are combined. The information on the setting of the locking step includes a keypad for inputting characters and patterns mixedly, the number of characters and patterns as authentication passwords, input values, and display methods of pattern images.

The display unit 13 may be formed of a liquid crystal display (LCD), and displays a menu of a mobile terminal, input data, function setting information, and various other information. In addition, when the display unit 13 is turned on and controlled in the lock mode, the display unit 13 displays a keypad for inputting a character and a pattern mixedly or a character keypad and a pattern keypad screen.

The input unit 14 includes a hardware keyboard composed of a plurality of character keys and pattern keys for receiving a command from a user. The display unit 13 and the input unit 14 may be implemented as a touch screen. In this case, the input unit 14 senses a user's touch input through a virtual keyboard displayed on the touch screen, and controls the detection result. It plays a role of conveying to (11). The input unit 14 generates a touch event corresponding to an unlock command of a predetermined password value while a screen related to unlocking of the mobile terminal is displayed on the touch screen, and transmits the generated touch event to the control unit 11. The unlock command for the predetermined password value includes a drag signal for inputting a predetermined pattern, a touched key corresponding to a character, and the like.

The input unit 14 includes a combination keypad consisting of a 3*4 character keypad from a letter a to a letter z and a pattern keypad consisting of 9 dots of 3*3 or a pattern keypad consisting of 12 dots of 3*4. Includes.

In addition, the input unit 14 includes at least one of a ring-shaped circle, an oval, and a square shape for displaying a pattern key, and includes a key on which a letter is written on the pattern key.

In addition, the input unit 14 inputs a text according to the start and completion of a touch of a key on a user's keypad, and completes and inputs a pattern according to the start and completion of a drag.

In addition, when the user's touch is sensed, the input unit 14 may input a character at the touched point and maintain the keypad as it is.

In addition, when a drag is detected, the input unit 14 inputs the drag image as a pattern but maintains the keypad, inputs the drag image as a pattern but displays a chain (trajectory) of the pattern, and the drag A method of displaying the keys as a pattern image, a method of converting the keypad to a pattern keypad, and a method of converting the keypad to the original mixed keypad when the pattern input is completed upon the end of the drag can be set and used.

Characters that can be input in the input unit 14 include English, alphabet, Korean, Chinese, Chinese, Japanese, Russian, Spanish, German, French, Portuguese, Indian, Malaysian, Vietnamese, Filipino, Thai, Arabic, and the rest of the countries. Of course, additional languages are possible.

The keypad of the input unit 14 may be provided with a character keypad and a pattern keypad, respectively, and a method of switching a keyboard by a tab or the like may be used. Another method is to input characters on the pattern key in a mixed, mixed, or mixed format, but the pattern consists of 12 dots and 26 English characters, so 2 to 3 English characters per pattern key. Assign. In this case, the selection of alphabetic characters can be selected by one (touch), two (two clicks), or three times (three clicks) touch, as in the conventional technique. For example, if English letters a, b, and c are assigned to the first pattern key, if you touch the pattern key once, a is input, if you touch it twice in a row, b is input, and if you touch three times in a row, c is input. .

In addition, the input unit 14 may include two keypads, the first keypad includes 12 pattern keys, and 12 out of 26 English alphabets (from A to L) are allocated, and the second keypad includes the remaining English. Alphabets (M to Z) can be assigned. In this case, the first keypad and the second keypad are switched using a screen flick (page turn) function or a tab (TAB). At this time, it goes without saying that the pattern can be input from either the first keypad or the second keypad.

On the other hand, in the keypad switching method, when flipping left and right, the first and second keypads are alternately switched regardless of the direction in which the first and second keypads are flipped left and right. Using the above method, a user can quickly and simply input a letter by touching one alphabet letter from a key once without having to select and input a letter by double tapping it, and the text can also be viewed in a larger size. However, since the two keypads can be switched using the screen flip, the keypad can be switched quickly and characters can be input with a single touch targeting large letters. In the keypad switching method using the tab (TAB), when the first tab (TAB) is selected, the first keypad appears, 12 pattern keys and English alphabets (from A to L) are mixed and displayed, and the second tab (TAB) is displayed. When selected, a second keypad appears, and 14 pattern keys and English alphabets (M to Z) are mixed and displayed.

Additionally, the input unit 14 may further include a number to be input. Accordingly, on a keypad on which letters and numbers are displayed, letters and numbers can be input by touch, and patterns can be input by dragging. For example, a user can enter letters, numbers, and patterns in combination, such as <a, 7, pattern, s, 4>.

The input unit 14 includes at least one of a touch screen of a mobile (smart phone) device, a touch screen of a cash dispenser, and a touch screen of a monitor.

For example, when the user inputs <b, l, u, pattern, e> as the authentication password on the input unit 14, the input unit 14 displays the detection results for <b, l, u, pattern image, and e>. It is transmitted to the control unit 11.

The input unit 14 is a 3*4 type character keypad or a pattern keypad, and a pattern key and a character key are combined to display a character on a circle indicating a pattern key, or a pattern key is superimposed on the character key and displayed as a mixed key.

On the keypad, when a user touches a specific mixed key, a corresponding character is input, and when a user is dragged, a pattern is input.

When the user drags the keypad, the dragged trajectory is displayed so that the user can see the dragging process well, the dragged keys are converted to a pattern, or the keypad is converted to a pattern keypad to input the pattern. You can set and use.

If the user does not want to expose the pattern image to completely block the exposure of the authentication password, the keypad remains unchanged even when the pattern is created by dragging, so that the image dragged by a third party cannot be viewed. It can be set and used.

The communication unit 15 transmits and receives a voice signal required for a call function and data required for data communication under the control of the control unit 11.

The control unit 11 performs an overall control function for the mobile terminal, and controls a signal flow between the respective constituent units. Specifically, after switching to the lock mode according to an embodiment of the present invention, the control unit 11 controls the input unit 14 to sense a user's touch. Accordingly, the controller 11 recognizes a pattern of a movement operation of the input touch position and an unlock command such as a character key corresponding to the touch position, and determines whether to unlock or not in response to the unlock command. In addition, the control unit 11 controls the display unit 13 to provide a user interface corresponding to the pattern of movement of the recognized touch position.

The operation of the controller 11 may control the overall operation of the present invention as described later with reference to FIGS. 2 to 3. The control of the control unit 11 may be implemented in software to handle the operation of the present invention.

Referring to FIG. 2, a user may set the unlock setting function by selecting an item related to the unlock setting from among various items of the unlock setting menu.

Accordingly, in step 200, the terminal determines whether a setting menu for unlocking a combination of characters and patterns using a keypad for mixing characters and patterns is selected by the user. If the unlocking setting menu is selected, a character and pattern mixed keypad 14 for setting the unlocking is displayed. For example, a character and pattern mixed keypad 14 that can be input by mixing characters and patterns according to an embodiment of the present invention is displayed.

Thereafter, in step 205, when the user touches a character on the keypad 14, the controller 11 receives the corresponding character of the key touched in step 210. If the user drags the keypad on the keypad 14 in step 215, the control unit 11 recognizes it as an input of a pattern in step 220 and receives a pattern image. When the user completes the input of characters and patterns by repeating the above process and commands the unlock setting (registration) in step 225, the controller 11 stores the characters and patterns input by the user in step 230 into the memory 12. Save the registration as an unlock password. When the lock release setting is completed through this process, the lock release setting registration process in which the character and the pattern are combined is terminated.

Meanwhile, the unlocking is a series of password values set by the user, can be set by the user, includes values and sequences of characters or patterns set by the user, and the number of passwords is set by the user. Of course, if the user does not separately determine the number of passwords, preset values in the authentication server are applied.

For example, a user can select a combination of characters and patterns as unlocking, and select a total of 5 unlocking systems with 4 characters and 1 pattern.

Accordingly, when the user selects the unlock method of the combination of characters and patterns as unlocking, the control unit displays the character and pattern combination keypad 14, and when the user presses the letter b, it is recognized as b, and when the user presses the letter l, the character l When the user drags the keypad in a Z shape, it is input as a pattern of a Z-shaped image, and when the user presses the letters u and e and selects the save button, the control unit is <b, l, pattern (Z), u , e> is recognized as unlocking, and the password is stored in the memory 12 as an authentication password for unlocking a combination of characters and patterns <b, l, pattern (Z), u, e>.

Hereinafter, as the operation of setting the unlocking of the character and pattern combination using the character and pattern combination keypad is completed through the process as described above, the terminal authenticates the unlocking of the character and pattern combination using the character and pattern combination keypad. Let's take a look at the behavior.

3 illustrates an authentication method using a character and pattern combination keypad in a terminal according to an embodiment of the present invention to unlock a combination of characters and patterns.

Referring to FIG. 3, the terminal determines whether there is a user input in step 400 in a waiting state for a lock release input. If there is a user input, if the user touches a key on the keypad in step 405, the controller 11 inputs the character touched in step 410. If the user drags the keys on the keypad in step 415, the control unit 110 recognizes it as an input of a pattern and inputs the pattern in step 420. When the above process is repeated and the user's unlocking input is completed in step 425, the control unit 110 stores the unlocking input information of the character and pattern combination input in step 430 and the unlocking information set stored in the memory 120. Compare for matches. Then, in step 435, it is determined whether the comparison result matches, and if the comparison result matches, the control unit 110 releases the lock in step 440.

An example of an unlock setting or authentication operation of a combination of a character and a pattern using such a character and pattern mixed keypad will be described with reference to FIGS. 4 to 18 and are as follows.

First, FIG. 4 is a screen of a character and pattern mixed keypad that can be input by mixing characters and patterns according to an embodiment of the present invention. Referring to FIG. 4, when the user touches the character G in step 4-a of FIG. 4, the character G is input. When the user touches twice, the letter H is input. If the user drags the keys, it is recognized as a pattern and a pattern image is input. Therefore, according to whether the character is touched or dragged, characters and patterns are separated and input.

5 is a screen of a character and pattern mixed keypad composed of 12 dots of 3*4 that can be input by mixing characters and patterns according to an embodiment of the present invention. Three alphabetic alphabets are assigned to one pattern key, and letters are selected with one touch, two touches, and three touches.

Referring to FIG. 9, in step 7-a, the alphabet A is combined with the first pattern key, and when the user touches A, A is input. Meanwhile, in FIG. 7, since only 12 of the 26 alphabets are assigned, the first keypad is changed to the second keypad of FIG. 8 by flicking left and right in step 7-b to switch to the second keypad.

8 is a screen of a second keypad showing the remaining characters of FIG. 7. 8, letters M to Z are assigned. When the user flicks in step 8-a, it is switched to the first keypad of FIG. 7. At this time, the flicking is switched regardless of left and right, and the first keypad and the second keypad are alternately displayed. At this time, the user can input the pattern from either of the two keypads.

9 is a shape of a combination key of a character key and a pattern key according to an embodiment of the present invention. Referring to FIG. 9, 9-a is a pattern key, 9-b is a letter key, and 9-c is a combination, heterogeneous, mixed, hybrid, mixed use of the 9-a pattern key and the letter key of 9-b, It is a mixed-blood, hybrid (two functions combined into one), and synthesized mixed-use keys. On the other hand, since the number of alphabets is 26, compared to 12 for the pattern keys, one, two, and three alphabets can be assigned to one key.

10 is a screen of a keypad for mixing characters and patterns according to an embodiment of the present invention. Referring to FIG. 10, a mixed keypad is devised in which a pattern keypad and a character keypad are combined, mixed, mixed, hybrid, and synthesized to receive characters and patterns, respectively.

11 is another screen of a keypad for mixing characters and patterns according to an embodiment of the present invention. Referring to FIG. 11, if the left half circle of the mixed key is touched in step 11-a, the letter A is input, and if the right half circle is touched in step 11-b, the letter B is input. Therefore, two letters are arranged on one key, but you can select by touching the semicircle only once without having to press twice to select letter B.

Next, FIG. 12 is a screen for setting registration and storing in a memory of a terminal for unlocking a combination of a character and a pattern using a keypad for mixing a character and a pattern according to an embodiment of the present invention. Referring to FIG. 12, when a user selects a menu for unlocking a combination of characters and patterns, a keypad for mixing characters and patterns according to a feature of the present invention is displayed. After that, if the user touches the character or drags the pattern, inputting <b, l, pattern, u, e> by unlocking the combination of the character and pattern in step 12-a is completed, and selecting registration in step 12-b. , The terminal stores <b, l, pattern, u, e> in the memory of the terminal as the unlock authentication password for <b, l, pattern, u, e>.

13 to 18 illustrate screens for inputting the unlocking of a combination of characters and patterns using a keypad for mixing characters and patterns according to an embodiment of the present invention. Referring to FIG. 13, on the keypad for mixing letters and patterns, the user inputs the first lock release authentication information by touching the letter AB mixed key twice in step 13-a. Then, since the control unit is a touch, it recognizes it as a character and receives the character B at the touched point twice. Next, when the user touches the letter L in step 14-a of FIG. 14, the controller receives the letter L as the second unlocking. Next, when the user drags the keys in step 15-a of FIG. 15, the control unit determines that it is a pattern input and receives the pattern input. When the user completes the drag in step 16-a of FIG. 16, the control unit receives the above pattern as the third unlocking authentication information. At this time, the keys on the keypad represent a method of additionally displaying channels (trajectories) while maintaining their original shape.

Next, when the user touches the letter U in FIG. 17, the controller receives the letter U as the fourth unlocking. Finally, when the user touches the letter E on the keypad for mixing letters and patterns according to the embodiment of the present invention in FIG. 18, the controller receives the letter E as the fifth unlocking. Through the above process, <B, L, U, pattern, E> was entered as the unlocking of the combination of characters and patterns.

19 is an example of the number of cases in which an authentication number is authenticated by a combination of inputting four characters and one pattern according to the present invention. Referring to FIG. 19, in step 19-a of FIG. 19, the pattern enters one of the first to fifth digits. Therefore, there are 5 input cases that distinguish 4 characters and 1 pattern.

20 shows the number of cases in which one pattern composed of nine dots can be input. The data in Fig. 20 are generally published data on the Internet and have been verified by a number of mathematicians (source Naver knowledge, blog, etc.). The number of cases in which more than 4 dots are connected out of the pattern consisting of 3 horizontal and 3 vertical dots is 389,112 (20-a).

21 is a number of cases in which an authentication number is authenticated by a combination of inputting a 4-digit character and one pattern according to the present invention. Referring to FIG. 21, since one pattern has the number of about 390,000 cases, one alphabetic character has 26, and four has 456,979 cases, the number of cases consisting of 4 characters and 1 pattern is 21- In step a, 390,000 times multiplied by 456,976 becomes about 180 billion. In addition, since there are five combinations, the number of unlocking cases according to the combination of four characters and one pattern according to the embodiment of the present invention is about 889 billion (889,074,226,560). That is, 26 * 26 * 26 * 26 * 389,112 * 5 = 889,074,226,560 (about 900 billion).

If three characters and one pattern are combined, the number of cases according to the embodiment of the present invention is 34.2 billion (34,195,162,560).

If a pattern image composed of 12 dots instead of 9 dots is used as the authentication number, the number of combinations of characters and patterns according to the present invention is infinitely increased. Also, when two or more different patterns or two or more identical patterns are input, the number of cases increases significantly.

The number of cases of about 900 billion (about 1 trillion) was obtained by combining the existing 4 characters and 1 pattern according to the characteristics of the present invention. Therefore, while the user has very high security, the unlock input and memory on the keypad for mixing characters and patterns are very simple. According to a feature of the present invention, in addition to having about 900 billion cases when characters and patterns are continuously input, it is difficult to easily memorize them and imitate them again even when a third party sees the pattern and character input.
