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

The present invention relates to an authentication method using a touch screen, and more particularly, to an authentication method and apparatus for processing an authentication password combining a character and a pattern.

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 (numbers and letters)] Passwords composed of numbers and letters 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. In addition, 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 numbers and letters.

[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 not previously used such as time difference, rhythm, beat, figure, and gradual unlock are proposed as unlocking methods, but the user feels a burden in having to memorize new things and 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 of cases, the size of the keyboard is small, and the number There are limitations such as the need to alternately switch between and input the English keyboard, the burden of memorizing new items, and the increase of 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.

Accordingly, the present invention provides a method and apparatus for fast and convenient authentication of a high security level.

In addition, the present invention provides a method and apparatus for controlling an authentication password combining characters and patterns in order to have a high level of security while using information that a user knows well in the past.

In addition, the present invention provides a method and apparatus for a mixed character and pattern input unit capable of inputting a character and a pattern in one input unit in order to quickly and simply input the character and pattern.

In order to achieve the above, the present invention provides an authentication method in an authentication server combining characters and patterns, the process of transmitting an input unit for mixing characters and patterns to a terminal device of a user requesting authentication, and a character and pattern from the terminal device. The process of receiving an authentication password combining the received character and pattern, and the process of determining whether the authentication password combining the received character and pattern matches the authentication password combining the previously set registered character and pattern, and if the comparison result is identical, the It characterized in that it includes a process of successfully terminating password authentication.

In addition, the present invention is a method of requesting authentication from an authentication server by combining a character and a pattern, the process of inputting an authentication password that combines a character and a pattern and transmitting it to an authentication server, and according to the input information from the authentication server. Receiving an authentication result, wherein the authentication server having an authentication password combining the character and the pattern includes a step of processing the authentication by determining whether the authentication password is a combination of the character and pattern in which the input information is stored in advance. It is characterized.

In addition, in an authentication system combining characters and patterns, the present invention provides a database for storing an authentication password that is a combination of a character and a pattern as an authentication password, as each member information, and a text for authentication from a terminal device through a communication network. It includes a server for receiving authentication input information combining patterns, comparing the authentication password of the terminal device with the combination of characters and patterns with the authentication password pre-stored in the database for authentication, wherein the terminal device inputs characters and patterns. When a character is touched in an injury, the touched character is inputted as authentication input information, and in the case of dragging, a pattern is inputted as authentication input information.

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

In addition, according to the present invention, when a user sets an authentication password by combining 4 characters and 1 pattern, about 900 billion cases are generated, so the security is much higher than that of the existing 6 characters 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.

(1) 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.

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

(3) Even when the smartphone is lost, it is difficult to understand the combination of the 4 digits of the password and the pattern, so the unlocking password does not leak.

(4) Input is simple and there is no need to memorize additionally. There is no need to memorize unfamiliar input elements such as conventional additional numbers, figures, time differences, rhythms, and beats.

(5) It is simply composed of 4 characters and familiar elements of the pattern, but the security and the number of cases are very high. About 900 billion cases occur.

(6) You can enter quickly and simply from one keypad without the need to switch between the character keypad and the pattern keypad.

2 shows a schematic configuration example of a terminal device for convenience of description. However, the terminal of the present invention is not necessarily limited to the above configuration. In addition, as an example of a terminal device according to an embodiment of the present invention, any device requiring user authentication, such as a smart phone capable of communication, a mobile phone, a personal computer, a notebook computer, a digital sound source playback device, and a portable multimedia player (PMP), is of course possible. .

First, the memory 12 stores various data generated and utilized by the terminal. 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 provided by a terminal and a combination of a character and a pattern. In particular, the memory 12 receives and stores an input unit 14 for inputting characters and patterns mixed with each other 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 characters 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 character password, a touched key corresponding to a drag signal for inputting a pattern, 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 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 character 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.

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 mixed, mixed, and mixed formats, but the pattern consists of 12 dots and 26 English characters, so 2 to 3 English characters on one pattern key. Assign. In this case, the selection of alphabetic characters can be selected by one touch, two times (two clicks) or three times (three clicks), 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, you will input a, if you touch it twice in succession, you will enter b, and if you touch it three times in succession, you will receive c. .

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 from the right to the left. 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 110.

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 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 character 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 character and a pattern and transmits it to the authentication server 30.

In addition, the control unit 11 receives an input unit for mixing characters and patterns from the authentication server and 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.

In addition, the control unit 11 maintains the keypad of the input unit 14 at the beginning according to a preset method according to a user's touch or drag, a method of displaying a chain of patterns (trajectory), and a method of displaying the dragged keys as a pattern image. 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 English letter b on the keypad, the controller 11 inputs the English letter b 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 <b, l, u, pattern image, e> 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 characters and patterns of the authentication server 30 according to an embodiment of the present invention. 3, the authentication server 30 for authentication combining characters and patterns according to the present embodiment includes a control unit 31, a database 40 storing an authentication password combining characters and patterns, and a communication unit 32. It consists of

First, when there is an authentication request from the terminal 10, the control unit 31 of the server transmits an input unit for mixing characters and patterns to the terminal 10. Thereafter, an authentication password combining characters 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 characters and patterns from the terminal 10, the control unit 31 determines whether the authentication password is correct by comparing it with the authentication password of the combination of characters and patterns stored in the database 40, and determines the result of 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 characters and patterns under the control of the control unit 31. In addition, the database 40 stores an input unit for mixing characters and patterns and provides it to the terminal 10. The authentication password stored in the database 40 is composed of a combination of characters and patterns, and preferably includes a password composed of 3 characters and 1 pattern, 4 characters and 1 pattern. The combination of 4 characters and 1 pattern is <pattern, character, character, character, character>, <character, pattern, character, character, character>, <character, character, pattern, character, character>, <character, character, Includes combinations such as character, pattern, character>, <character, character, character, character, pattern>. The number of the combinations is determined according to the user's selection, and is combined in the same manner as in the above example, and the description of the other number of examples is the same, and thus is omitted.

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

Hereinafter, a setting method of setting and registering an authentication password of a character and pattern combination using a character and pattern mixed input unit 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 character and pattern combination using a character and pattern mixed input unit is selected by the user. If the authentication password setting menu is selected, a character and pattern mixed input unit 14 for setting the authentication password 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 the pattern. If the user completes the input of the character and pattern by repeating the above process and commands the password setting in step 225, the control unit 11 transmits the character and pattern input by the user to the authentication server 30 in step 230. . Then, the authentication server 30 stores the text and pattern combination authentication password input from the terminal 10 in step 235 in the database 40 as an authentication password of the text and pattern combination. When the authentication password setting is completed through this process, the authentication password setting registration process that combines the character and the pattern is terminated.

Meanwhile, the authentication password 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, the user can determine the combination of characters and patterns as the authentication password, and select a total of five authentication encryption systems, including 4 characters and 1 pattern.

Accordingly, when the user selects the combination of character and pattern authentication encryption method as the authentication password, the control unit displays a keypad for mixing characters and patterns, and when the user presses the letter b, it is recognized as b, and when the user presses the letter l, it is input as the letter 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 each letter u and e and selects the save button, the control unit selects <b, l, pattern (Z), u, e>. Recognized as an authentication password, the password is transmitted to the authentication server, and the authentication server stores <b, l, pattern (Z), u, e> as an authentication password of a combination of characters and patterns in the database.

Hereinafter, through the process as described above, a character and a character using a character and pattern mixed keypad

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 characters and patterns using a keypad for mixing characters and patterns in the terminal will be described.

5 illustrates an authentication method using a character and pattern combination authentication password using a character 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 character on the keypad in step 405, the controller 11 recognizes the character 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 character 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 user's character and pattern combination registered and stored in the database 40 and compares it with 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.

Among the patterns consisting of 3 horizontal and 3 vertical 9 dots, the number of cases in which more than 4 dots are connected is 389,112 (28-a).

29 is a number of cases in which an authentication number is authenticated by a combination of four-digit characters and one pattern input according to the present invention. Referring to FIG. 29, 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 29- In step a, 390,000 times multiplied by 456,976 becomes about 180 billion. In addition, since there are five combinations, the number of authentication passwords 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).

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.

According to the present invention, the number of cases of about 900 billion was obtained by combining the existing four digits and one pattern. Therefore, while the user has very high security, the input and memory of the authentication password on the keypad for mixing characters and patterns is 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.
