Description

{Method and Device for Password and Unlocking Input using the Combination of Password Number and Pattern Image}

The present invention relates to an authentication method using a touch screen, and in particular, to an authentication method and an apparatus for processing an authentication password combining a number and a pattern using a mixed input unit capable of inputting a number and a pattern, respectively.

The following shows the existing authentication encryption method and features.

[Numeric PIN Password] The 4-digit numeric PIN password has a number of about 10,000 cases, but there is a risk that it could be leaked in public places. Accordingly, there is a way to enter 6 digits of the password, but all 6 digits must be memorized, but human heads are usually difficult to memorize more than 4 digits. There is a limit that requires a lot of time and effort to enter the 6-digit number.

[Password (letters and numbers)] Passwords composed of letters and numbers are highly secure because there are many cases. However, as a side effect of the opposite, the user has to memorize and input a lot of data. Since 10 numbers and 26 English letters have to be selected on the small screen of the smartphone, inputting is inconvenient and time-consuming when using a keypad. There is an inconvenience of having to input while switching between the numeric keypad and the character keypad. In particular, with an aging society, the aging population increases, and accordingly, it is difficult for the elderly to memorize and enter complex letters and numbers.

[Pattern image drawing] For a pattern composed of 9 dots, input by connecting 4 or more dots in a row. At that time, the pattern has a number of about 320,000 cases, so the security is very high. However, when using a pattern, when only 4 to 6 points are connected, there is a problem that the number of cases is not large and that a third party who sees the situation of drawing the pattern can easily follow it.

[Others] New methods that are not previously used such as time difference, rhythm, beat, figure, and gradual unlock are proposed as unlocking methods, but users feel the burden of having to memorize new things and to learn how to use or be used to input. There is a point.

As described above, authentication encryption methods such as 4 digits of conventional numeric PINs, patterns, 6 to 8 digits or more of a combination of alphabets and numbers, and other time differences do not have a large number, small size of the keyboard, and numbers and English. There are limitations such as the need to alternately switch and enter the keyboard, the burden of memorizing new items, and increasing the number of inputs to increase security.

Therefore, the necessity for a new concept of security authentication method with high level of security is required, although input is simple without additional memorizing by using information that users already know well.

Such data includes data generated according to the execution of an application by the terminal, and all types of data that can be generated using the terminal or received and stored from the outside. In particular, data according to an embodiment of the present invention may include authentication password information obtained by combining numbers and patterns provided from the terminal. In particular, the memory 12 receives and stores an input unit 14 for inputting by mixing numbers and patterns from the authentication server 30.

The display unit 13 may be formed of a liquid crystal display (LCD), and displays a menu of a terminal, input data, function setting information, and various other information. In addition, the display unit 13 displays a screen corresponding to the authentication password.

The input unit 14 includes a hardware keyboard or the like capable of inputting a plurality of numbers and patterns mixedly for receiving a command from a user. 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 transmits the detection result to the control unit 11. Will play a role. The input unit 14 generates a touch or drag event corresponding to an authentication password command of a predetermined password value while a screen related to the authentication password is displayed on the touch screen, and transmits the generated touch or drag event to the control unit 11. The authentication command for the predetermined password value includes a predetermined numeric password, a touched key corresponding to a drag signal for inputting a pattern, 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.

In addition, the input unit 14 inputs a number according to the start and completion of a touch of a key on the input unit of the user, and inputs in a pattern unit according to the start and completion of a drag.

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

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 <8, 3, 4, pattern, 9> as the authentication password on the input unit 14, the input unit 14 displays the detection result for <8, 3, 4, pattern image, and 9>. It is transmitted to the control unit 110.

If the user does not want to expose the pattern image to completely block the exposure of the authentication password, the keypad remains as it was in the state that the pattern is created by dragging, so that a third party cannot see the dragged image. Can be used.

The communication unit 15 transmits and receives data necessary for data communication required for authentication under the control of the control unit 11.

The control unit 11 performs an overall control function for the terminal 10, and controls the signal flow between the respective constituent units. Specifically, the control unit 11 controls the input unit 14 to detect a user's touch after switching to the authentication password setting or input step according to an embodiment of the present invention. When a touch is detected, the touched number is input, and when a drag is detected, it is input as a pattern. Accordingly, the control unit 11 recognizes an authentication password according to a combination key of an input number and a pattern and transmits it to the authentication server 30.

In addition, the control unit 11 receives an input unit for mixing numbers and patterns from the authentication server, stores the input unit in the memory 12, and controls the input unit to be displayed on the display unit 13 when a user requests authentication.

It controls to show 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.

For example, when the user touches the number 4 on the keypad, the controller 11 inputs the number 4 as the authentication password. If it is a Z-shaped drag, the control unit 11 inputs a Z-shaped image pattern. When the user inputs <8, 3, 4, pattern image, 9> as the authentication password on the input unit 14 to set the authentication password, the control unit 11 transmits the input authentication password to the authentication server 30. .

3 shows the configuration of a server for authentication by combining the number and pattern of the authentication server 30 according to an embodiment of the present invention. Referring to FIG. 3, the authentication server 30 for authentication combining numbers and patterns according to the present embodiment includes a control unit 31, a database 40 storing an authentication password combining numbers and patterns, and a communication unit 32. It consists of

First, when there is an authentication request from the terminal 10, the controller 31 transmits an input unit for mixing numbers and patterns to the terminal 10. Thereafter, an authentication password combining numbers and patterns is transmitted from the terminal 10 and stored in the database 40 as an authentication password. In addition, when there is a request for verification of an authentication password combining a number and a pattern from the terminal 10, the control unit 31 determines whether the authentication password is correct by comparing it with the authentication encryption of the number and pattern combination stored in the database 40, and sends the result to the communication unit. It controls the transmission to the terminal 10 through (32).

The control unit 31 includes at least one of a stock transaction, a bank financial transaction, a mobile banking, an internet shopping, a game, a door lock, and a portal site authentication server.

The database 40 stores an authentication password that combines numbers and patterns under the control of the controller 31. In addition, the database 40 stores an input unit for mixing numbers and patterns and provides it to the terminal 10. The authentication password stored in the database 40 is composed of a combination of numbers and patterns, and preferably includes a password composed of 3 numbers and 1 pattern, 4 numbers and 1 pattern. The combination of 4 numbers and 1 pattern is <pattern, number, number, number, number>, <number, pattern, number, number, number>, <number, number, pattern, number, number>, <number, number, Includes combinations such as numbers, patterns, numbers>, <numbers, numbers, numbers, numbers, patterns>. The number of combinations is determined according to the user's selection, and is combined in the same manner as in the above example, and descriptions of other examples are the same, and thus will be omitted.

The communication unit 32 is responsible for requesting and transmitting an authentication password that combines numbers and patterns between the terminal 10 and the authentication server 30.

Hereinafter, a setting method of setting and registering an authentication password of a combination of numbers and patterns using the input unit for mixing numbers and patterns according to an embodiment of the present invention will be described with reference to FIG. 4.

Referring to FIG. 4, a user may set an authentication password setting function by selecting an item related to authentication password setting from among various items of the authentication password setting menu provided by the authentication server 30.

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

Thereafter, in step 205, when the user touches a number on the keypad 14, the controller 11 receives the corresponding number 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 the pattern. When the user completes the input of the number and pattern by repeating the above process and commands the password setting in step 225, the control unit 11 transmits the number and pattern input by the user in step 230 to the authentication server 30. . Then, the authentication server 30 stores the number and pattern combination authentication password input from the terminal 10 in step 235 in the database 40 as the authentication password of the number and pattern combination. When the authentication password setting is completed through this process, the authentication password setting registration process combining the number and the pattern is terminated.

On the other hand, the authentication password 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 authentication server are applied.

For example, the user can decide how to combine numbers and patterns as the authentication password, and select a total of five authentication encryption systems, four numbers and one pattern.

Accordingly, when the user selects a combination of numbers and patterns as an authentication password, the control unit displays a keypad for a combination of numbers and patterns, and when the user presses the number 3, it is recognized as 3, and when the user presses the number 4, it is inputted as number 4, 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 numbers 7 and 2 and selects the save button, the control unit selects <3, 4, pattern (Z), 7, 2>. It recognizes as an authentication password and transmits the password to an authentication server, and the authentication server stores <3, 4, pattern (Z), 7, 2> as an authentication password of a combination of numbers and patterns in the database.

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

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

5 illustrates an authentication method using a number and pattern combination authentication password using a numeric and pattern mixed keypad in a terminal according to an embodiment of the present invention.

Referring to FIG. 5, the terminal determines whether there is a user input in step 400 while waiting for an authentication password input. If there is a user input, if the user touches a number on the keypad in step 405, the controller 11 recognizes the number touched in step 410 as an authentication password. If the user drags the keypad on the keypad in step 415, the controller 11 recognizes it as a pattern in step 420. When the above process is repeated and the user input is completed in step 425, the control unit 11 transmits the authentication password of the number and pattern combination input in step 430 to the authentication server 30. Then, in step 435, the control unit 31 of the authentication server 30 reads the authentication password of the combination of the number of users registered and stored in the database 40 and compares the input authentication password. As a result of the comparison, if the authentication passwords match in step 440, the control unit 31 transmits the authentication success to the terminal 10 in step 445.
