Description

Authentication method using pattern input

The present invention relates to an authentication method using a pattern input. More specifically, when a pre-stored pattern is input to a pattern input window displayed on a display of a user terminal having a touch screen, a password or a pattern is stored in a web server stored therein. The present invention relates to an authentication method using a pattern input for executing an application installed in a user terminal.

BACKGROUND ART As the popularity of small electronic devices or terminals equipped with a touch screen for contacting a hand or a stylus pen to input information increases, technologies for inputting a password or inputting information by a touch method for user authentication have been disclosed.

Recently, in order to unlock the smartphone, users simply input the information by dragging sideways or up and down (drag) .However, in order to increase security and prevent unauthorized use, the user inputs a pattern (pattern) of a user-specified form in order. The method is also widely used.

The user can have the same effect as entering a password or a password by inputting the pattern in the position and order specified in the pattern input window displayed on the touch screen.

1 is a conceptual diagram illustrating a pattern input method according to the prior art.

Most mobile user terminals, such as smartphones and tablet PCs, are made without a cover, so that after a certain period of time after use or the display is turned off by the user's operation, they enter a locked state. To use the device again, the user must enter a password or enter a pattern.

As shown in FIG. 1, the pattern input window 104 is displayed on the display 102 having a touch screen type provided in the user terminal 100. The pattern input window 104 is implemented in various ways, but is widely used is a window composed of nine buttons of three columns and three columns. Each button is typically numbered from 1 to 9. The user passes by touching each button in a predetermined order. The control unit of the user terminal 100 detects a start point, a waypoint, and an end point of a pattern (touch operation) input by the user, and checks whether the pattern matches the content stored by the user.

If it does not match, a re-entry request or access denied message is displayed. If it matches, it unlocks the user terminal 100 to enable the use.

However, users enter a password not only to access their terminal but also to log in to an internet website, etc. It is much faster and easier to input a pattern by a touch method rather than entering a password. However, in the existing terminal, since the pattern is simply stored only in its own terminal, there is an inconvenience in that the user cannot input the pattern to the website (web server) to which the user wants to log in and use the user authentication method.

An object of the present invention for solving the above problems is to provide an authentication method using a pattern input to enable easy and fast password input and site access by using a pattern that is made continuously on the touch screen as a password for logging in to the server. do.

In another aspect, the present invention provides an authentication method using a pattern input for inputting a preset pattern by a touch method to execute an application (application software program) installed in a user terminal such as a smart phone, and only if the application is matched. It aims to do it.

In addition, an object of the present invention is to provide an authentication method using a pattern input to enable the use of a pattern consisting of a cursive handwriting or a plurality of characters by enabling the input of a plurality of discontinuous patterns in the process of inputting the pattern.

The present invention devised to solve the above-described problem is an authentication method using a pattern input consisting of a touch and drag on the touch screen as the authentication information for logging in to the server 400, the control unit 202 of the user terminal 200 When the user inputs a pattern for authentication in the pattern input window displayed on the display, the controller 202 inputs the setting pattern and authentication information input by the user for authentication to the server 400 through the network 300. A first step of transmitting and storing; A second step of the control unit 202 displaying a pattern input window on a display of the user terminal 200 when the user wants to log in to the server 400; A third step of transmitting, by the controller 202, the input pattern to the server 400 when a user inputs a pattern in the pattern input window displayed in the second step; And a fourth step of allowing the server 400 to log in to the user terminal 200 when the server 400 compares the input pattern with the setting pattern.

If the server 400 compares the input pattern with the setting pattern does not match, the server 400 further comprises a fifth step of rejecting the login of the user terminal 200.

The authentication information is characterized in that the user ID or password.

The pattern input through the pattern input window is formed by sequentially connecting one or two or more individual patterns, and the individual patterns are formed by any number of waypoints between one start point and one end point.

The present invention according to another embodiment is an authentication method using a pattern input consisting of a touch and drag on the touch screen as authentication information for executing a specific application installed in the user terminal 200, the control unit 202 of the user terminal 200 If the user inputs a pattern for authentication in the pattern input window displayed on the display, the controller 202 is a first step of storing the setting pattern in the application information about the specific application; A second step of the controller 202 displaying a pattern input window on a display of the user terminal 200 when a user intends to execute the specific application; A third step of, when the user inputs a pattern into the pattern input window displayed in the second step, the authentication processing unit 206 compares the input pattern with the setting pattern; And a fourth step of causing the control unit 202 to execute the application 208 when the input pattern matches the setting pattern as a result of the comparison in the third step.

As a result of the comparison in the third step, if the input pattern and the setting pattern do not match, the control unit 202 further includes a fifth step of refusing to execute the application 208.

According to the present invention, when accessing a website or executing an application using a user terminal equipped with a touch screen, an effect of simply and quickly inputting a graphic pattern by a touch method without inputting a password of numbers or letters is possible. There is.

Hereinafter, an "authentication method using a pattern input" (hereinafter referred to as an "authentication method") according to an embodiment of the present invention will be described with reference to the drawings.

2 is a block diagram showing the structure of a user terminal according to an embodiment of the present invention.

In order to use the authentication method of the present invention, an application is installed in the user terminal 200, or a program for realizing the authentication method is installed in the server 400 operating a website. In the present invention, the server 400 includes not only a web server for accessing a website, but also a DB server for storing data, an FTP server for storing and using files, and the like.

The user terminal 200 is connected to the server 400 through the network 300. The network 300 of the present invention includes both wired and wireless communication networks, and corresponds to 3G or 4G mobile communication networks or wired and wireless Internet networks.

The control unit 202 generates data about a pattern to be used by the user for accessing the server 400 or executing an application, and the storage 204 stores data about a setting pattern stored by the user for authentication. The authentication processing unit 206 checks whether the pattern input by the user and the setting pattern stored in the storage 204 match and transmits the result to the control unit 202.

The application 208 is an application installed by the user. In the present invention, the application is specifically selected by the user, and means an application executed only by input of a pattern.

3 is a flowchart illustrating a process of logging in to a server using a pattern input, and FIG. 4 is a conceptual diagram illustrating a multi-pattern input method.

First, the control unit 202 displays a pattern input window arranged in the same form as in the prior art on the display of the user terminal 200 for input and storage of a pattern to be used as a password.

The user inputs a pattern in a desired form on the pattern input window of the display, and the control unit 202 stores the input pattern as a setting pattern for future authentication.

As shown in Fig. 4, the user touches and drags the buttons displayed on the pattern input window in any order in order to input the setting pattern. Commonly used methods (patterns entered to unlock the lock screen on smartphones) use patterns that are dragged at once without releasing the touch from the start point to the end point. In other words, "one starting point", "one end point" and "any number of waypoints" exist in one setting pattern.

In the present invention, the number of start points and end points can be arbitrarily set. However, if you set one button press to a pattern, you can see the same starting point, end point, and waypoint. In addition, the pattern consisting of two buttons can be seen as consisting of only the starting point and the end point, in this case, the pattern input method of the present invention can be applied.

As shown in FIG. 4, the user may bundle four patterns and use them as one setting pattern. The pattern illustrated in FIG. 4 is described with the number of buttons as shown in the following [Table 1].

개별패턴 1 Individual Pattern 1	①-②-③-⑥-⑨①-②-③-⑥-⑨
개별패턴 2 Individual Pattern 2	②-⑤-④-⑦-⑧②-⑤-④-⑦-⑧
개별패턴 3 Individual Pattern 3	⑥-⑤-④-①-②-③⑥-⑤-④-①-②-③
개별패턴 4 Individual Pattern 4	⑦-④-⑤-②-③⑦-④-⑤-②-③

As a result, the pattern shown in FIG. 4 is stored as four start points, four end points, and thirteen waypoints, and a whole connection pattern of four individual patterns consisting of "starting point-waypoint-end point" becomes one setting pattern. The storage 204 stores information on such a total setting pattern.

The user touches and drags on any button to start inputting the setting pattern. When the pattern of one's desired form (a form including one or more individual patterns) is completed, a separate completion button (not shown) is pressed to indicate that the input of the setting pattern is finished.

If the user wants to access the website using the user terminal 200 while the setting pattern is stored, the user terminal 200 accesses the server 400 that operates the website through the network 300. Should be. To this end, the user terminal 200 first transmits and stores information for authentication to the server 400 (S106).

Authentication information to be sent to the server 400 includes a user ID and password, and a setting pattern. In some cases, the password may be omitted, which will be described later.

In addition, the user executes a browser in the user terminal 200 to log in to the server 400, enters a domain of the corresponding website, or clicks a shortcut icon. At this time, the control unit 202 displays a pattern input window on the display, and the user inputs the same pattern as a previously stored setting pattern by a touch and drag method. (S108) In this case, the user's name or ID must be input together. In some cases, while using the unique number of the user terminal 200 may be excluded the input of the name or ID.

The pattern input by the user is transmitted to the server 400 through the network 300, and the server 400 checks whether the input pattern is the same as the previously set pattern for storing. (S110) For the two patterns to match, the starting point, waypoints, and end points must all be the same. That is, the order from the starting position to the ending position can be viewed in the same pattern only by the same, and the server 400 compares all of these situations.

If the input name or ID is checked for access, and the input pattern is the same as the setting pattern stored in the server 400, the server 400 allows the user terminal 200 to log in. (S112) If set If it is not the same as the usage pattern, the server 400 transmits a login rejection message and terminates the access or inputs the pattern again.

5 is a conceptual diagram illustrating the structure of various types of pattern input windows.

FIG. 5 shows a case where 4x3 buttons are arranged horizontally and vertically (a), when 3x4 buttons are arranged (b), and when 4x4 buttons are arranged (c). . But you can also arrange the buttons in various ways.

6 is a block diagram illustrating a state in which a pattern and a password are stored together in a server, and FIG. 7 is a block diagram illustrating a state in which a pattern is stored in a server.

As described above, the server 400 stores information (user ID, password, pattern, etc.) for user authentication, and can vary the range of authentication information to be stored in advance in order to increase security while facilitating user access. have.

The first is to store the setting pattern and the password entered by the user together with the server 400, as shown in FIG. When the pattern for login is transmitted from the user terminal 200, the server 400 checks whether the pattern is the same as the setting pattern, and extracts the user's password to use for login if it matches. Therefore, the pattern sent by the user is used to extract the password.

Second, as shown in FIG. 7, only the setting pattern is stored in the server 400 without a password. In this case, if the pattern input from the user terminal 200 is the same as the setting pattern, the login is immediately performed. Therefore, the pattern itself that the user sends becomes a password.

Any one may be used to use the method of the present invention.

In the above-described example, the user terminal 200 has stored and authenticated the setting pattern in order to log in to the server 400. For this purpose, the setting pattern and the password (optional) must be stored in the server 400. .

However, a user may use a pattern to execute a specific application installed in his user terminal 200.

First, the control unit 202 displays the pattern input window as before (S202).

The user inputs a desired pattern as a setting pattern (S204).

The controller 202 stores the setting pattern together in the application information about the specific application 208 (S206).

Thereafter, when the user touches an icon to execute the corresponding application, the controller 202 displays a pattern input window, and the user inputs a pattern by touching and dragging the pattern input window (S208).

The authentication processing unit 206 checks whether the input pattern is the same as the setting pattern stored for execution of a specific application (S210).

If the input pattern is the same as the stored setting pattern, the controller 202 executes the corresponding application 208. (S212) If the pattern does not match, the controller 202 outputs an execution rejection message, The pattern is input again (S214).

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the above-described technical configuration of the present invention may be embodied by those skilled in the art to which the present invention pertains without changing its technical spirit or essential features of the present invention. It will be appreciated that the present invention may be practiced as. Therefore, the above-described embodiments are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the appended claims rather than the detailed description, and the meaning and scope of the claims and All changes or modifications derived from the equivalent concept should be interpreted as being included in the scope of the present invention.
