Hereinafter, a system and an input method for inputting a security key using the graphic element according to the present invention will be described in detail with reference to the drawings.

1 is a block diagram illustrating a system for inputting a security key using graphic elements according to an embodiment of the present invention.

As shown in the figure, a system for inputting a security key using a graphic element includes a control unit 101, a display unit 102, an operation unit 103, and a display unit 104.

The system for inputting the security key may be an automatic teller machine (ATM) or an automatic teller machine (ATM) that performs user authentication and approves withdrawal or transfer of money, and may be a door lock for authenticating the passengers of a door . The above configuration corresponds to a component that is essential for performing the process of inputting the security key according to the present invention. The security key input device according to the present invention is applicable to other components As shown in FIG. Hereinafter, for the sake of convenience of explanation, concrete examples will be explained by taking the case of a security key of an automatic teller machine and a door lock as an example.

The control unit 101 includes a graphic input means generation unit for generating a graphic input means 105 having a plurality of graphic elements and a keypad input function for inputting a security key. The plurality of graphic elements may be predetermined patterns such as combs, dot patterns, and may be red, yellow, and certain figures. The graphic element can be used in the present invention as long as it is a graphic element that can be identified by a user in addition to the pattern, color, and picture. In addition, the graphic element may be composed of only a pattern, or a combination of a color and a pattern.

The graphic input means 105 has a three-dimensional shape, and each of the three-dimensional surfaces has different graphic elements. The three-dimensional shape can be a polyhedron, such as a cube or a rectangular parallelepiped.

The graphic input means 105 has a keypad input function for inputting a security key in addition to the graphic elements. The keypad may be a conventional keypad for inputting numbers from 0 to 9, or a keypad for inputting 1 to 9 numbers or various special characters. The graphic input means 105 may be configured as a cuboid of 3 × 3 × 3 × 3 × 3 in the case of having nine numeric identification marks as shown in FIG. 2, and in the case of including an identification mark having nine or more numbers, It may be 4x4x4 rather than a 3x3x3 array in a polyhedron, and it may have various shapes.

The graphic input unit 105 is displayed on the display unit 102 to recognize a graphic element as a user and to recognize information of the keypad. The display unit 102 may be implemented using a commonly used display device such as an LCD or the like and may be capable of directly inputting information by touching the display unit 102.

The display means 104 displays information of graphic elements corresponding to the security key among the plurality of graphic elements. For example, when the security key is composed of four digits, four graphic elements corresponding to each number are displayed, and if the security key is five digits, five corresponding graphic elements are displayed. In this case, each graphical element may be different, partly different, or all the same.

The operation means 103 has a function of operating the graphic input means 105 in order to select a graphic element corresponding to the information of the graphic element displayed on the display means 104. [ The operating means 103 may be displayed on the display unit 102 together with the graphic input means 105 as shown in Fig. In addition, the graphic input means 105 can be directly operated by touching. In the case of directly operating the display unit 102, it is preferable to use an electrostatic touch pad.

The display means 104 may be displayed together on the display unit 102 and may be implemented using a separate panel as shown in FIG. 4 for higher security. As described above, when information is obtained in order to steal a security key, generally, the display unit 102 is photographed and information thereof is obtained. In this case, it may be more advantageous to implement the display means 104 using a separate panel at a position different from the angle of the display unit 102.

2 to 4 illustrate a cube-shaped graphic input means having different patterns and a keypad for inputting numerals 1 to 9, the display means 104 is separately configured, The operating means 103 is displayed on the display unit 102 together with the graphic input means 105. [ The display unit 102 uses a touch-type display, and the security key is a 4-digit number. A graphic element corresponding to the four-digit number of the security key is displayed on the display means 104. The user selects a face having the same pattern as the corresponding graphic element by using the operation means 103, To input one digit of the security key. Then, a face having the same pattern as the second graphic element displayed on the display means 104 is selected by using the operating means 103 and the security key is inputted. By repeating this process, you have to enter the 4 digits of the security key, but the security key is completely entered.

For higher security, the display means 104 may be displayed on the terminal 106 owned by another user as shown in Fig. In this case, the terminal and the control unit must perform synchronization using separate communication means (107, 301).

In addition, the graphic element corresponding to the security key and / or the identification mark displayed on the keypad may be provided in a one-time format. In this case, it provides higher security than the existing one. In order to provide the graphic elements and the identification mark in a one-time format, the management server 200 including the one-time graphic element and the identification mark providing unit 210 and the security key input system are configured as shown in FIG. 6 and must be synchronized with each other . 7, when the display unit is displayed on the display unit 303 of the separate terminal 300, the security key input system, the management server 200, and the terminal 300 must be synchronized with each other, Synchronization can be used for systems used in systems that provide a common one-time-format security key.

In addition, the numerals or special symbols of the identification mark may be located at random, and the numerals or special symbols of the identification mark on each face of the three-dimensional polyhedrons of the graphic input means may be different from each other when provided in a one-time format .

Further, every time the graphic input means is provided in a one-time format, the three-dimensional polyhedron changes its shape so that even if the input operation is hacked, security of the security key is assured when the changed polyhedron is used as the input means .

Fig. 8 shows another embodiment of the present invention.

In this embodiment, the identification mark of the graphic input means 505 is displayed on the display unit 303 of the separate terminal 300. That is, the graphic input unit 505 includes a keypad including a plurality of graphic elements and one or more null keys whose identification mark is deleted, and can input a security key. The identification mark displayed on the display unit 303 of the terminal 300 may be displayed in the same shape as that of the graphic input means 505 and may be displayed by expanding the respective faces.

In addition, the display means 305 for displaying the information of the graphic element corresponding to the security key may be displayed on the terminal 300 or may be displayed on the display unit 502 of the security key input system. That is, the display means 305 can select the position in consideration of various matters such as the type of the system, the security of the place where the system is located, and the like, according to various forms to be performed.

In order to use a separate terminal, it is necessary to synchronize with the security key input system, which can be performed using a separate communication means. The communication means is preferably NFC, wireless LAN, Bluetooth, magnetic field communication, etc. In order to provide a one-time type security key and graphic element, synchronization between a security key input system, a management server and a terminal should be performed.

Another embodiment of the present invention is a method of inputting a security key. Such a method can be implemented in software, mounted in hardware, or implemented in a virtual space such as the Internet.

A control unit implemented using a processor such as a CPU generates graphic input means having a plurality of graphic elements and a keypad input function, displays the generated graphic input means on a display unit, . Then, the user sets the graphic element of the same graphic input means as the graphic element corresponding to the security key by operating the graphic input means, and inputs the security key. When there are a plurality of security keys, a process of setting a graphic element corresponding to each security key and inputting a security key may be repeated.

The graphic input means is formed of a three-dimensional polyhedron, and the graphic elements are defined by combining one or more colors, pictures, and patterns.

When the portion displaying the graphic element corresponding to the security key is implemented in a separate terminal, the terminal and the apparatus displaying the graphic input means may add a step of performing synchronization using a separate communication means.

The graphic element and / or the identification mark corresponding to the security key may add a step provided in a one-time format.

Another embodiment of the method of inputting another security key of the present invention is characterized in that when displaying the graphic input means, one or more null keys whose identification mark of the keypad is deleted may be included, It can be displayed on the terminal. In the case of being displayed on a separate terminal, the terminal and the input device can be synchronized using a separate communication means.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.

According to the present invention, since the graphic element corresponding to the security key is additionally input, the security is improved. Therefore, this feature can be used in industries in the field of security systems.
