Description

[0001] The present invention relates to a method of unlocking a character and a pattern in a mobile terminal,

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

2. Description of the Related Art [0002] In recent years, due to the rapid development of communication technology, functions in a mobile terminal have been gradually expanded, and various user interfaces (UI) and various functions using the same have been provided.

In particular, a mobile terminal equipped with a touch screen is equipped with various methods of input device lock / unlock functions to limit unnecessary input errors in a standby state or to restrict use by other users. Generally, the mobile terminal performs a lock function only when the activation of the lock function is selected by the user. For this purpose, the user can select one of locking schemes such as a pattern, a numeric PIN, and a password to set a locking function of the mobile terminal.

In the case of a mobile terminal having a lock function, the lock function is activated when there is no input from the user for a predetermined period of time. Accordingly, if the user does not input the specific function of the mobile terminal for a predetermined period of time, the screen or function of the mobile terminal becomes inactive. At this time, the conventional mobile terminal releases the lock mode by predefined for releasing the lock mode, for example, the touch screen hold state, or by the password input defined by the setting of the user.

As described above, the mobile terminal activates the lock function every time the waiting time for waiting for user input elapses. In addition, recently, bank funds are now actively traded through the use of smart phones.

In addition, when a user sets a complicated password or pattern to enhance the security of the mobile terminal, a lot of effort is required compared with the case of releasing the lock function using a simple password or pattern. Conversely, if you use a simple password or pattern to reduce hassle, you may be exposed to a third party or there may be a security issue. Therefore, there is a need for a user authentication of a simple mobile terminal, which is capable of maintaining high security by preventing unintended input errors or theft by a third party, which is the original purpose of the locking function.

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

The present invention also provides a method and apparatus for authenticating a locking function of a mobile terminal by combining characters and patterns so that a user can provide a high level of security using information that he normally knows.

The present invention also provides a method and apparatus for a character and pattern keypad capable of inputting characters and patterns on a single keypad for quickly and simply inputting the characters and patterns.

According to another aspect of the present invention, there is provided a method of unlocking a combination of characters and patterns in a mobile terminal, the method comprising the steps of: receiving an unlock command combining a character and a pattern from a user after setting a lock mode; Comparing the received lock release command with a lock release command set to a combination of a pattern and a pattern; and releasing the lock mode when the comparison result indicates that the combination of the character and the pattern match.

According to the present invention, when a user sets an authentication password by combining a 4-digit character and a single pattern, the number of cases of about 900 billion is generated, . On the other hand, users do not have to memorize new password entries, they are easy to forget, easy to input and easy to input.

Also, according to the present invention, since the character keypad and the pattern image keypad can be integrated into one keypad and inputted, it is possible to input quickly and simply without switching between the character keypad and the pattern keypad.

Authentication password leakage is difficult. It is difficult for a third person who sees the password character 4 digits and the pattern image to be continuously input to remember and follow it all.

Entering the authentication password is simple and short. One letter and one pattern can be entered sequentially on the same keyboard keypad.

Even when the smartphone is lost, it is difficult to grasp the combination of four characters and patterns, so that the unlock code is not leaked.

It is composed of four characters and a familiar element of patterns, but the number of security and cases is very high. There are about 900 billion cases.

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. FIG. 1 shows a schematic configuration example of a mobile terminal for convenience of explanation. However, the mobile terminal of the present invention is not necessarily limited to the above configuration. In addition, examples of the mobile terminal according to the embodiment of the present invention may be any device that requires user lock such as a personal computer, a notebook, a digital sound reproducing device, a portable multimedia player (PMP)

First, the memory 12 stores various data generated and utilized in the mobile terminal. Such data includes data generated according to the application execution of the mobile terminal, all types of data that can be generated using the mobile terminal, received from the outside, and stored. Particularly, the data according to the embodiment of the present invention may include a user interface provided in the mobile terminal, various setting information according to the use of the mobile terminal, and information on the setting of the lock step in which characters and patterns are combined. The information on the setting of the lock step includes a keypad for inputting characters and patterns in a mixed manner, the number of characters and patterns as authentication ciphers, the respective input values, and the display method of the pattern image.

The display unit 13 may be formed of a liquid crystal display (LCD), and displays menus, input data, function setting information, and various other information of the mobile terminal. Further, when the display unit 13 is controlled to be turned on in the lock mode, a keypad or a character keypad and a pattern keypad screen for inputting characters and patterns are displayed.

The input unit 14 includes a hardware keyboard composed of a plurality of character keys and pattern keys for receiving commands 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 or the like displayed on the touch screen, (11). The input unit 14 generates a touch event corresponding to an unlock command of a predetermined encryption value in a state where a screen related to unlocking the mobile terminal is displayed on the touch screen, and transmits the touch event to the controller 11. The unlock command of the predetermined encryption 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 mixed keypad including a 3 * 4 character keypad from letters a to z, a pattern keypad consisting of 9 points of 3 * 3 points, or a pattern keypad consisting of 12 points of 3 * 4 .

Also, the input unit 14 includes at least one of a ring-shaped circle, an ellipse, and a rectangular shape indicating a pattern key, and includes a key in which a character is written in the pattern key.

The input unit 14 inputs characters in accordance with the start and end of the touch of a key on the user's keypad, and completes and inputs a pattern according to the start and completion of the drag.

Also, when the user touches the input unit 14, the user can input characters of the touched point and maintain the keypad.

In addition, when the drag is detected, the input unit 14 inputs a corresponding drag image as a pattern but keeps the keypad as it is, a method of inputting the drag image as a pattern but displaying a chain (trajectory) of the pattern, The keypad is switched to the pattern keypad, and when the pattern input is completed according to the end of the drag, the keypad can be switched to the original mixed keypad.

The input characters on the input unit 14 include alphabets, alphabets, Korean, Chinese, Japanese, Russian, Spanish, German, French, Portuguese, Indic, Of course, the language of course is possible.

The keypad of the input unit 14 may include a character keypad and a pattern keypad, respectively, and a keyboard may be switched using a tab or the like. Another method is to use mixed, mixed, and mixed forms including characters on a pattern key. However, the pattern is composed of 12 points and 26 alphabetic characters, so that two or three alphabetic characters I will assign it. In this case, selection of the alphabetical character can be selected by one touch (touch), two times (twice), or three times (three times), as in the conventional technique. For example, if the first pattern key is assigned an alphabetic letter a, b, or c, the pattern key is touched once, then a is received, then b is continuously touched twice, and c is touched three times consecutively .

Also, the input unit 14 may include two keypads. The first keypad includes 12 pattern keys, and 12 of the 26 English alphabets (A to L) are allocated. On the second keypad, Alphabet (M to Z) can be assigned. In this case, the first keypad and the second keypad are switched using a screen flipping function (page turning function) or a tab (TAB). In this case, the pattern can be input from either the first keypad or the second keypad.

On the other hand, if the keypad switching method is turned to the left or to the right, the first and second key patters are alternately switched regardless of the direction of turning to the right and left. With this method, the user can easily input one alphabetic character in one key by simply touching it twice, without having to select and input a character by double-clicking, and the letter can be enlarged. However, since the switching of the two keypads can be switched by using the screen flip, the character can be input by touching the large character quickly by switching the keypad quickly. When the first tab (TAB) is selected, a first keypad is displayed and 12 pattern keys and an English alphabet (A to L) are displayed in a mixed manner, and a second tab (TAB) is displayed When selected, the second keypad appears and 14 pattern keys and the English alphabet (M to Z) are mixed.

In addition, the input unit 14 may further include a number. Accordingly, in the keypad on which characters and numbers are displayed, letters and numbers are inputted by touching, and patterns can be inputted by dragging. For example, the user can input a combination of letters, numbers, and patterns such as <a, 7, pattern, s, 4>.

The input unit 14 includes at least one of a touch screen of a mobile (smartphone) device, a touch screen of an ATM, and a touch screen of a monitor.

For example, if the user inputs <b, l, u, pattern, e> as the authentication password on the input unit 14, the input unit 14 outputs the detection results for <b, l, u, pattern image, e> To the control unit (11).

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

When the user touches a specific combination key on the keypad, the character is input, and when the user presses a specific combination key, the character is input.

When the user drags the keypad, a dragged trajectory is displayed to allow the user to view the dragging process, a dragged key is displayed by switching to a pattern, or a pattern is input by switching the keypad to the pattern keypad Can be set and used.

If the user does not want to expose the pattern image in order to completely block the exposure of the authentication password, the keypad remains unchanged even when the pattern is generated by dragging, so that the third person can not see the image dragged Can be set and used.

The communication unit 15 transmits and receives voice signals necessary for the call function and data necessary 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 the signal flow between the respective components. Specifically, the control unit 11 controls the input unit 14 to detect a touch by a user after switching to the lock mode according to an embodiment of the present invention. Accordingly, the control unit 11 recognizes the unlock command such as the pattern of the movement of the touch position, the character key corresponding to the touch position, and the like, and decides whether or not to release the lock in response to the unlock command. Also, the control unit 11 controls the display unit 13 to provide a user interface corresponding to the recognized movement pattern of the touch position.

The operation in the control unit 11 can control the overall operation of the present invention as described below with reference to FIGS. The control of the control unit 11 may be implemented by software to handle the operation of the present invention.

Referring to FIG. 2, the user can set the unlock setting function through selection of items related to the unlock setting among various items of the unlock setting menu.

In step 200, the terminal determines whether the unlock setting menu of the combination of characters and patterns using the keypad of the character and pattern combination is selected by the user. If the unlock setting menu is selected, a character and pattern combination keypad 14 for unlock setting is displayed. For example, a character and pattern keypad 14 capable of inputting a combination of characters and patterns according to an embodiment of the present invention is displayed.

When the user touches a character on the keypad 14 in step 205, 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 controller 11 recognizes the input of the pattern in step 220 and receives the pattern image. If the user completes the input of the character and the pattern and then instructs the unlock setting (registration) in step 225, the control unit 11 stores the characters and the pattern inputted by the user in the memory 12 in step 230, And stores it as an unlock password. When the unlock setting is completed through this process, the unlock setting registration process of combining the characters and the pattern is ended.

On the other hand, the unlocking is a set of password values set by the user, which can be set by the user, including the values and order of letters or patterns set by the user, and the number of passwords is set by the user. Of course, if the user does not determine the number of ciphers separately, the preset values in the authentication server are applied.

For example, a user can select a combination of characters and patterns by unlocking, and select a total of five unlocking schemes, four letters and one pattern.

Accordingly, if the user selects the unlocking method of the combination of the character and the pattern by unlocking, the control unit displays the character and pattern keypad 14. When the user presses the character b, the character is recognized as b, (Z), u (u), u (u), and u (e), when the user drags the keypad in Z shape, , e> by unlocking and stores the password as an unlocking authentication code of a combination of letters and patterns in the memory 12 as <b, l, pattern (Z), u, e>

Hereinafter, the unlocking of the combination of characters and patterns using the character and pattern combination keypad is completed through the above-described process, so that the unlocking of the combination of characters and patterns using the keypad of the character and pattern combination As shown in FIG.

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

Referring to FIG. 3, in step 400, the terminal determines whether there is a user input in a waiting state waiting for an unlock input. If there is a user input, in step 405, if the user touches the key on the keypad, the controller 11 inputs the corresponding character touched in step 410. If the user drags the keys on the keypad in step 415, the controller 110 recognizes the input of the pattern in step 420 and inputs the pattern. If the unlocking input of the user is completed in step 425, the controller 110 displays the unlock input information of the character and pattern combination input in step 430 and the unlock information stored in the memory 120 Compare whether they match. If it is determined in step 435 that the comparison results match, the controller 110 releases the lock in step 440.
