Embodiment Construction

[0023] Taking the QR code as an example, the specific implementation process of the present invention is described in detail:

[0024] 1. Generate a product identification QR code, such as figure 1 shown. When making a QR code, you can leave some white border around the QR code.

[0025] 2. If figure 2 As shown, the product packaging design drawing is obtained, and the color of the drawing is displayed through the CMYK color channel using the picture editing software. The present invention obtains the CMYK color atlas of the selected area by calling Photoshop, such as image 3 shown.

[0026] Since the K channel needs to be replaced by the CMY color channel, and the ideal CMY color cannot be obtained in the actual application process, the perfect K channel color cannot be obtained by the color replacement method. Therefore, when selecting the packaging area, it is necessary to select the K channel value between 30 and 80, so as to improve the color replacement effect unde...

Abstract

The invention discloses a two-dimensional code hiding method. According to the invention, through utilization of the principle that CMY channels are mixed according to a certain proportion and can replace a K channel in the CMYK color channels, fixed-point replacement is conducted on a pattern of the specific area of the package according to the shape of the two-dimensional code pattern, different areas with different light and shade can be detected through an infrared detection device, and the scanning function can be achieved through the infrared detection device, therefore the hidden two-dimensional code can be detected and cannot be seen by naked eyes under the natural illumination condition, and then the purpose of commodity two-dimensional code hiding is achieved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a two-dimensional code hiding method, a hidden two-dimensional code scanning method, an infrared scanner and a storage device. Background technique [0002] With the development of information technology and the real economy, the value of commodity information is getting higher and higher. Merchants hope that by printing unique identification codes on product packaging, they can record the entire process of product production and sales and realize product traceability. However, the traditional barcode has a low information storage capacity, and it is difficult to realize one code per item; the two-dimensional code has a large information storage capacity, fast recognition speed, strong error correction ability, and widespread application. Therefore, many merchants store unique product identification codes through two-dimensional codes. The most common two-dimensiona...
