Description

QR code information input/output method and device therefor

The present invention provides a method of issuing QR code having a link value of an arbitrary sub-domain or sub-folder (sub-directory), providing information input, modification, and deletion rights to clients accessing through the link, and exposing the input information and to an apparatus for implementing the same.

QR Code is one of the most comprehensively used information storage methods. QR Code itself can contain a lot of information, and more information can be connected through network connection.

QR code can store up to 7089 numeric characters, 4296 characters, and 1817 Chinese characters, and Hangul can store about 1700 characters, which is similar to Chinese characters. Since QR code includes ECC (Error Correction Code), which is an error correction code, information can be restored even if a part is lost. Data can be lost for various reasons such as various noises and physical reasons, and information that does not match 100% becomes incomplete data that cannot be interpreted by a computer. Therefore, in the QR code that stores data outside the computer, ECC is a very important information storage and transmission means. The QR code has an error recovery level, and if the error recovery level is raised, the error recovery ability is improved, but the size of the QR code image increases as the data increases. Conversely, if the error recovery level is lowered, the size of the image becomes smaller and more data space can be secured to contain pure information.

The error recovery level of QR code is called level L, M, Q, H in 4 steps. Data can be restored at 7%, 15%, 25%, and 30% levels in order from Level L to H. In general, in an environment where QR code is easily contaminated, Level Q or H is selected, and if it is used in a place with a large amount of data and low risk of contamination, level L is often selected.

However, QR code contains information that has already been confirmed at the time of creation, and it is not possible to modify it. This is due to the characteristic that the form of the QR code is determined based on already confirmed information.

Therefore, the existing QR code has been used in the form of storing the link value of the domain or containing the product information that has already been determined. Therefore, since there is no way to modify the information already stored in the QR code, a method of modifying information has been used as a method of modifying the information stored in the storage device of the link value stored in the QR code.

However, in the case of QR code containing individual information, there was a problem that the client could not input, modify, or delete information in the link value of the QR code. This is because it is useful as a method to check already stored information, but it is not possible to input, modify, or delete information. This is because, in the case of an externally disclosed QR code, it is dangerous to give an external accessor the right to control the information of the server because it has a link value that specifies product information or induces access to a specific domain.

When one piece of information linked to a specific QR code is modified, there is a problem in that the modified information is exposed to a large number of users using the same QR code, so it is difficult to transmit the control right of the information to the outside.

Hereinafter, a QR code information input/output system and method will be described with reference to the accompanying drawings.

1 is a view showing the overall configuration of a QR code information input/output system according to an embodiment of the present invention, and is largely a link generation module 100, a QR code generation module 102, an input information existence checking module 104, The link database 106, the QR code database 108, and the main server 10 composed of the input information database 110, etc., and a plurality of client terminals 170 connected through a wired/wireless communication network (not shown) may be configured. .

In an embodiment of the present invention, the client terminal 170 includes an image recognition device 120 , a QR code recognition module 130 , an information input device 140 , an information output device 150 , and a network connection device 160 , etc. As a computing device including, examples thereof may include, but are not limited to, a smartphone, a personal computer, a notebook computer, a tablet PC, and the like.

The main server 10 is for managing the QR code. It generates a connectable QR code based on a predetermined link value, and can set information on the QR code in the connected client terminal 170 based on the predetermined link value. interface can be provided.

First, the link generation module 100 is connected to a plurality of client terminals 170 through a wired/wireless communication network, and may create a subdomain or subfolder (subdirectory) having one or a plurality of arbitrary link values.

In this case, the generated link value may be stored in the link database 106 storing the information.

The QR code generation module 102 generates a QR code including link value information and then issues it. At this time, the generated QR code is stored in the QR code database 108 .

When the client terminal 170 connects through the link value, that is, through the recognition of the QR code, the main server 10 transfers the information stored in the link value through the input information existence confirmation module 104 to the input information database 110. , and if there is no stored information, an information input window may be exposed to the accessed client terminal 170 , and information received from the client terminal 170 may be stored in the input information database 110 .

On the other hand, when the client terminal 170 connects to the main server 10 through the link value, if there is information already stored through the input information existence check module 104 and the input information database 110 , the connected client terminal Information stored in the input information database 110 in 170 may be transmitted to the client terminal 110 .

The network configuration diagram of the main server 10 and the client terminal 170 of FIG. 1 is configured on the assumption that each embodiment is executed, and the configuration of the main server does not need to include all of them. It will be said that the main server 10 including only the necessary components according to each embodiment described below also falls within the scope of the present invention.

2 is a flowchart illustrating an information input/output method of a QR code according to an embodiment of the present invention, and FIGS. 3 to 4 are exemplary diagrams of information input/output of a QR code according to an embodiment of the present invention.

As shown in Fig. 2, the main server 10 creates an arbitrary subdomain or subfolder (subdirectory) in the domain and generates a link value thereof (S200). There may be one or a plurality of subdomains or subfolders (subdirectories) having an arbitrary link value, and each has a unique link value. The main server (1) generates a QR code having the link value (S202) and stores the value in the main server (10). The QR code may be provided as an image and may be provided online or offline, or may be provided by being attached to a product in the offline case. When the QR code is scanned by the client terminal 170 (S204), the main server 10 and the client terminal 170 are connected using the link value stored in the QR code (S206).

The main server 10 checks whether there is input information stored in the link value in the input information database 110 through the input information existence confirmation module 104 (S208). For example, the client terminal 170 that has generated the QR code having the link value and connected for the first time does not have information that can be displayed because the main server 10 does not have the input information. Accordingly, the main server 10 displays an information input window for inputting information on the client terminal 170 (S210). For example, the main server 10 may display an information input window as shown in FIG. 3 on the client terminal 170 . Information S212 input through the client terminal 170 may be transmitted to the main server 10 and stored in the input information database 110 of the main server 10 . Thereafter, when the QR code having the link value is rescanned (S214) through the client terminal 170, the information input above may be displayed on the client terminal 170 (S216).

That is, even when the QR code having the same link value is scanned by the client terminal 170, the client terminal ( 170), and when stored information exists, an information exposure window as shown in FIG. 4 exposing input information is exposed to the client terminal 170. FIG.

As described above, if one wants to manage by inputting one piece of information into a plurality of QR codes, when the information input window is exposed by accessing the main server 10 through a separate QR code, information is input to the client terminal 170 ), it is also possible to input information by using the remaining information as it is.

5, as the client terminal 170 recognizes the QR code and accesses the main server 10, the main server 10 opens an information input window for inputting information about the link value to the client terminal. It is provided to 170 (S300), and as information input is completed, an interface for setting authentication means such as a password is provided (S302).

The main server 10 matches the input information with the password as the authentication means, such as a password, is set, and stores it in the input information database 110 (S304). Specifically, the main server 10 may match the information input to the link value and the password and store it in the input information database 110 .

When the client terminal 10 reconnects to the main server 10 using the link value (S306), the main server 10 displays the information stored in the input information database 110 on the client terminal 170 ( S308).

Thereafter, when there is a request for information modification (S310) from the client terminal 170, the main server 10 provides an input for an authentication means, for example, an input request for a password to the client terminal 170, and then the input password and information It is determined whether the user has the right to correct information through comparison between the passwords matched to (S312).

As a result of the determination of S312, when it is determined that the authority to modify information is provided, the main server 10 provides an interface capable of information management such as modifying or deleting information stored in the link value of the QR code through the client terminal 170 ( S314).

The foregoing description of the present application is for illustration, and those of ordinary skill in the art to which the present application pertains will understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present application. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a dispersed form, and likewise components described as distributed may be implemented in a combined form.
