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

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

According to the present invention, when a user sets an authentication password by combining 4 digits and 1 pattern, there are about 20 billion cases, so that the security is much higher than that of the existing number and 6 digits or pattern input. 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 the numeric keypad and the 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 numeric keypad and the pattern keypad.

It is difficult to leak the authentication password. It is difficult for a third party who sees 4 digits of the password and inputs the pattern image in succession to remember it all and imitate it.

The authentication password input is simple and short. Numbers and 1 pattern can be entered consecutively on the same keypad.

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

It is simply composed of 4 digits and familiar elements of the pattern, but the security and the number of cases are very high. About 20 billion cases occur.

In addition, when the display unit 13 is turned on and controlled in the lock mode, the display unit 13 displays a mixed keypad or a numeric keypad and a pattern keypad screen for inputting numbers and patterns mixedly.

The input unit 14 includes a hardware keyboard composed of a plurality of numeric 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 number, and the like.

The input unit 14 is a combination keypad consisting of a 3*4 numeric keypad of numbers 0 to 9 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 indicating a pattern key, and includes a key in which a number is written on the pattern key.

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

In addition, when the user's touch is sensed, the input unit 14 may input the number of 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 used.

The keypad of the input unit 14 may be provided with a numeric keypad and a pattern keypad, respectively, and a method of switching a keyboard by a tap or the like may be used. Another method is to input numbers on the pattern key in a mixed, mixed, or mixed format, but since the pattern consists of 12 dots and the number is 10, one number is assigned to one pattern key.

In addition, the input unit 14 may include two keypads, and the first keypad may include a pattern keypad and the second keypad may include a numeric keypad. In this case, the first keypad and the second keypad are switched (FIGS. 22 to 23) using a screen flick (page turn) function (FIGS. 20 to 21) or a tab TAB.

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. In the keypad switching method using the tab TAB, when the first tab TAB is selected, a first keypad appears and a numeric keypad. When the second tab TAB is selected, a second keypad appears and a pattern keypad may be displayed.

For example, when the user inputs <8, 4, pattern, 3, 9> as the authentication password on the input unit 14, the input unit 14 controls the detection result for <8, 4, pattern, 3, 9>. Pass it to (11).

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

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. If the user completes the input of the number and pattern by repeating the above process and commands the unlock setting (registration) in step 225, the controller 11 stores the number and pattern 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 number and the pattern are combined is terminated.

On the other hand, the unlocking is a series of password values set by the user, can be set by the user, includes a value and order of a number or pattern 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 mobile terminal are applied.

For example, the user can select a combination of numbers and patterns for unlocking, and select a total of 5 unlocking systems, 4 numbers and 1 pattern.

Accordingly, when the user selects the unlocking method of the combination of numbers and patterns as unlocking, the control unit displays the numeric and pattern combination keypad 14, and when the user presses the number 8, it is recognized as 8, and when the number 4 is pressed, the number 4 When the user drags the keypad in the shape of Z, the pattern of the Z-shaped image is input. When the user presses the numbers 3 and 9 and selects the save button, the control unit is <8, 4, pattern, 3, 9>. Is recognized as unlocking, and the password is stored in the memory 12 as an unlock authentication password of a combination of numbers and patterns <8, 4, pattern, 3, 9>.

Hereinafter, through the process as described above, numbers and numbers using a keypad mixed with numbers and patterns

As the operation of setting the unlocking of the pattern combination is completed, an operation of authenticating the unlocking of the combination of numbers and patterns using a keypad for mixing numbers and patterns in the terminal will be described.
