Description

Encryption QR code generator and method {Encryption QR code generator and method}

The present invention relates to the generation of encrypted QR codes, and in particular, when a data array is provided, encrypted QR codes are automatically generated in batches, thereby reducing the generation time of a plurality of encrypted QR codes and minimizing user intervention. It relates to a device and method for generating an encrypted QR code that enables

In general, a barcode, which is a kind of optical code, encodes letters, numbers, symbols, etc. to be easily read optically through a combination of black bars and white bars between them. It is widely used in various fields because input is simple and data processing system configuration is possible.

However, information encoded in such a one-dimensional barcode is expressed only by the width of a bar extending in a single dimension and a blank space. Since all bars and spaces have a uniform height in their vertical direction, information is stored only in the horizontal direction of the one-dimensional barcode. Therefore, since data must be recorded within a certain width, there is a disadvantage in that only a limited amount of data can be recorded.

In recent years, as the demand for information technology has increased, there has been an increasing demand for removing associated databases and storing more information in the code itself. As a result of this demand, since the mid-1980s, a two-dimensional barcode has emerged as an extension of the one-dimensional barcode. These two-dimensional codes are flattened by arranging data in both axes (X-axis direction and Y-axis direction), and the problem of one-dimensional barcodes, that is, the limitation of data expression, has been expanded. These two-dimensional barcodes can be generally classified into two categories. That is, one is a stacked barcode, in which another one-dimensional barcode is overlapped on top of a one-dimensional barcode, and the other is a matrix barcode, which is designed as a true two-dimensional matrix.

A QR code, which is a matrix barcode, has a square shape and can be recognized by dark and light squares (finder pattern; recognizer) located at the three corners of the code. Because of the recognizer, the QR code code can be quickly read by the CCD array camera.

In addition, since the existing two-dimensional barcode displays information as a single image, there is a problem in that it can be copied by a method such as copying like paper. In order to prevent this, a password may be input when displaying a barcode, but the inconvenience of having to input a password is accompanied and an additional burden occurs for password management.

Meanwhile, with the recent development of information technology including mobile communication, various services are provided by combining a mobile communication terminal and a 2D barcode. For example, by using SMS or MMS, a two-dimensional barcode containing predetermined information (data) is transmitted to the user's mobile communication terminal, and various information recorded in the barcode is used to obtain an ID card or gift certificate for identification. It is used as a means of verifying authenticity. However, when personal information is converted into a two-dimensional barcode (eg, QR code) and used, there is a problem in that personal information is leaked to an unauthorized third party.

In order to improve this problem, recently, efforts have been made to protect information even when the QR code is leaked through the generation of an encrypted QR code.

A conventionally proposed method for generating an encrypted QR code is shown in FIG.

As shown in Figure 1, the conventional encryption QR code generation method,

When the user inputs data to generate an encryption QR code (S11), selects an encryption method (S12), and inputs an encryption key (S13), individual input data is encrypted using the encryption key with the selected encryption method (S12). S14).

Subsequently, a QR code is generated using the encrypted individual data (S15).

Since this encryption QR code generation method is a method of generating an encryption QR code for individual data, the more data there is, the more the encryption QR code generation time increases. In addition, since it is a method of individually selecting and inputting an encryption method and an encryption key for one individual data, user intervention is increased, causing a lot of inconvenience in generating the overall encryption QR code.

In particular, when an encrypted QR code is generated by encrypting a QR code attached to a public bicycle or public electric kickboard in the same way as above, the number of public bicycles or public electric kickboards installed nationwide is immeasurably large, so the encrypted QR code The generation time of , requires a lot of time, and waste of human resources for generating an encrypted QR code also occurs.

On the other hand, another conventionally proposed technology for generating an encrypted QR code is disclosed in <Patent Document 1> to <Patent Document 2> below.

The prior art disclosed in <Patent Document 1> encrypts the plaintext and password according to the operation of the optical code issuer to generate the ciphertext and the secret key, and generates the encrypted optical code for the secret key and the ciphertext based on the code matrix. Include steps. Accordingly, even if personal information or various information requiring confidentiality is converted into an optical code, it is possible to prevent unauthorized recipients from reading personal information or various information requiring confidentiality.

However, even in this method, it is impossible to generate a plurality of encrypted QR codes using a file having a continuous data arrangement.

In addition, the prior art disclosed in <Patent Document 2> provides a technique of distributing a public key for encrypting data using a QR code and encrypting data using the public key included in the QR code.

However, this prior art is a method of distributing a public key for data encryption using a QR code, and it is impossible to encrypt and provide the QR code itself.

In response to the encrypted sequentially encrypted data, an encrypted QR code is generated in batches.

The detailed description of the "apparatus and method for generating an encrypted QR code" according to the present invention configured as described above is as follows.

First, a user who wants to generate an encryption QR code inputs data to be encrypted in a file-type data array through the data input unit 110 (S101).

Here, the data arrangement in the form of a file may be a form in which encryption target data is arranged in an Excel sheet. In the present invention, an Excel sheet is mentioned in the form of a file, but the present invention is not limited thereto, and the same effect can be obtained by using any file as long as it is a file capable of sequentially recording data.

Next, the encryption unit 140 automatically extracts data to be encrypted from the input data array (S102). Individual data is extracted as data to be encrypted in order from the data array input in the form of a file. Here, one individual data is generated as one encrypted QR code.

In addition, the user determines an encryption method to encrypt the extracted data to be encrypted through the encryption method selector 130 (S103). Here, as the encryption method, various encryption methods widely known in the field of data encryption may be used among a public key encryption method, a Diffie-Hellman (DH) secret exchange encryption method, and an RSA encryption method using a public key. A user may select one of a variety of preset encryption methods.

In addition, the user sets an encryption key to encrypt the data to be encrypted through the key input unit 120 (S104). That is, an encryption key to encrypt data to be encrypted is input. Here, the encryption key may use various key information such as a phone number and an ID.

Next, the encryption unit 140 sequentially encrypts the data of the data array using the encryption key based on the determined encryption method (S105).

That is, individual data is sequentially extracted as encryption target data from the input file-type data array, and individual data is sequentially encrypted from the first encryption target data to the last encryption target data in the file-type data array. Therefore, if there are 1000 pieces of individual data, there are also 1000 pieces of encrypted data.

As described above, the present invention automatically sequentially encrypts all data arrangements in a file form by a single intervention of inputting data to be encrypted in the form of a file using a data arrangement, selecting an encryption method and inputting only an encryption key. It is done. Accordingly, as in the past, the inconvenience of requiring users to intervene the same as the number of data to be encrypted is eliminated, and the problem that QR code generation time increases proportionally to the number of QR codes generated by user intervention for each individual data is also solved. can be solved collectively.

Next, the QR generating unit 150 sequentially and automatically generates encrypted QR codes using data sequentially encrypted through the encryption unit 140 (S106 to S109).

That is, the first individual data extracted from the input file-type data array is extracted as encryption target data, and a QR code is generated using the encrypted data of the extracted first encryption target data (S106). Next, it is checked whether the extracted individual data is the last data (S107), and if it is not the last data, the next individual data is automatically extracted (S108), and the process moves to step S103, and the following steps are repeated to generate a QR code. do. Through this process, encrypted QR codes are generated in batches in response to the sequentially encrypted data encrypted in order from the first encryption target data to the last encryption target data in the file-type data array.
