Description

Dual QR code for counterfeit and forgery prevention

The present invention relates to a QR code, and more particularly, to a dual structure forgery prevention QR code that combines a microcode part of an embedded structure and a general code part of a print structure to prevent forgery and falsification.

A QR code (quick response) is a two-dimensional code composed of a plurality of cells of a monochrome grid pattern. The combined pattern of each cell includes information such as a position symbol, an alignment symbol, version information, format information, Lt; / RTI > A QR code can contain a lot of information in a small enough space to record a maximum of 7,089 characters, a maximum of 4,296 characters, and a maximum of 1,817 Chinese characters.

Especially, as the spread of smart phones is expanding rapidly, the usage of QR codes is rapidly increasing. In contrast to general mobile phones, various applications can be freely installed and executed in a smart phone, and a QR code scanner program using built- The main reason for this is that the environment for using QR codes has been developed.

In addition, QR code can be made small size of 10mm x 10mm, and error recovery function has an advantage of restoring data information even if a part of code is dirty or damaged. Since the shape of code is square, Reading can be accurately recognized.

The QR code, which is highly applicable and scalable as a code system, is also used as a marketing tool to easily inform consumers of various events and discount event information based on the logistics distribution industry field, and is widely used for business cards, signs, And can be used to authenticate authenticity of various articles and documents. For example, by displaying QR codes on agricultural products and imported goods, consumers can easily identify information on the production and distribution process of agricultural and fishery products on a smartphone simply by scanning or photographing QR codes on a smartphone. You can check the customs information, and you can easily check whether the specific product is a domestic manufactured product or a low-priced imitation imported from abroad.

However, since applications and software for making QR codes can be easily obtained from the Internet, anyone can produce QR codes, and since the QR code generators have high possibility of forgery and modulation, It is urgently needed to prevent forgery and falsification of QR codes. In recent years, QR codes have been reproduced more easily by the development of printing technology and by specialized counterfeiting organizations.

Especially when the QR code is used for the authentication of authenticity and distribution of agricultural products, such as agricultural products and imports, unauthorized use of the QR code forged or tampered with the counterfeit product shakes the health of the distribution structure. For this reason, there is a need to develop a forgery-proofing QR code that can prevent a QR code from being forged or modified by using a public QR code generator.

In addition, the conventional QR code is printed on the outside of the wrapping paper and is easily damaged due to interference or friction with an external object, thereby causing frequent errors in information recognition. In addition, since the conventional QR code has a size of about 10 mm x 10 mm, it is difficult to recognize information due to its curvature when attached to a small spherical or curved container that is gradually miniaturized.

Specifically, the first code unit 100 may be a semiconductor process. For example, after a pattern is designed, a wafer mold is manufactured by processes such as masking, exposure and etching, a soft mold is formed by using the wafer mold, and the pattern of the soft mold is transferred to a film Thereby filling the recessed portion with the pigment. The pattern of the embedded structure formed by the above process can realize a micro pattern of nano unit, and micro QR code having a very small size as 5 mm x 5 mm or 2 mm x 2 mm as a whole can be manufactured.

Therefore, since the first code unit 100 must be subjected to a semiconductor process such as masking, exposure, and etching processes in a fine three-dimensional pattern having an embedded structure, it is practically impossible to falsify (reproduce) in a distribution process. Also, even if the first code unit 100 is attached to a rectangular or curved container with a small QR code, the information can be easily recognized.

The second code unit 200 is formed along the outer side of the first code unit 100 and is formed by a printing process using a conventional QR code generator.

[ The dual QR code can be scanned only when the identification information of the code part of the first code part 100 and the code part of the second code part 200 match. Therefore, if the second code unit 200, which is relatively easy forgery and falsify, makes a forgery and falsification, the QR code is changed according to the identification information of the second code unit 200 stored in the first information of the first code unit 100 at the time of scanning The information is not recognized or the information is forged.

The second information of the second code unit 200 may include information for limiting the number of scans of the second code unit 200 and real time information of the second code unit 200 printed on the second code unit 200. The information for limiting the number of scans has an effect of arbitrarily restricting the distribution phase of the product, and it is possible to block repetitive scanning attempts on the forged second code unit 200. In addition, the time information on which the second code unit 200 is printed provides real-time information on the commodity provided to the trader at the time the commodity is circulated, so that the commodity purchaser can receive the commodity, Detailed information can be found.

In the description of the present invention, the dual QR code exemplifies the configuration in which the first code unit 100 is disposed inside the second code unit 200, but the first code unit 100 and the second code unit 200 may be arranged adjacent to each other and arranged side by side. That is, the second code unit 200 may be disposed around the first code unit 100.

Therefore, the first code unit 100 can provide information also by the arrangement structure of the pattern cells PC1 'in the second area 120. [

The inversion of the first region 110 or the second region 120 may be performed by changing the shape, size, and line width of the fine patterns 130 constituting each of the pattern cells PC1 and PC1 ' Or the like.

For example, the fine pattern 130 of the first code unit 100 may have a structure in which a plurality of stripe shapes are arranged at predetermined intervals, and further, the stripe line width w1 of the first region 110 may be a The stripe line width w2 of the second area 120 is twice as wide as the stripe line width w2 of the area 120 or the stripe line width w2 of the second area 120 is twice as large as the stripe line width w1 of the first area 110, (W1 = 2 * w2 or w2 = 2 * w1). That is, the stripe line width w1 of the first area 110 and the stripe line width w2 of the second area 120 have a multiple relation. The stripe pattern of the first area 110 and the second area 120 having different line widths w1 and w2 may be combined with the plurality of microlenses 321 to provide a lenticular pattern do.

At this time, the intervals of the stripes in the regions 110 and 120 will be equal to the line width thereof. The stripe may be configured by arranging a plurality of rectangular shapes in the longitudinal direction.

The inversion of the first region 110 or the second region 120 may be realized by a structure in which the fine patterns 130 are arranged at a predetermined interval with a plurality of square or dot shapes having a predetermined width.
