Embodiment Construction

[0039] The present invention provides a color digital matrix two-dimensional code and its anti-counterfeiting method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] see figure 2 , a color digital matrix two-dimensional code, including a pattern area 1 for printing a two-dimensional code pattern, one side of the pattern area 1 has a check code area 2 for printing a digital matrix, and the digital matrix consists of a two-dimensional code sequence Number generation, the serial number of the two-dimensional code is divided into nine groups of numbers, which are printed on the side of the two-dimensional code pattern in the form of a nine-square grid. The size of the nine-square grid is adapted to t...

Abstract

The invention discloses a color figure matrix two dimension code which comprises a pattern area for printing a two dimension code pattern, one side of the pattern area is provided with a check code area used for printing a figure matrix, the figure matrix is printed in a form of nine rectangle grids on one side of the two dimension code pattern, figures in all grids are printed in different colors and therefore a color figure matrix is obtained; when anti-fake operation is performed, a scanning device is used for conducting scanning operation, and a two dimension being scanned code is compared with a two dimension code pattern pushed via a client end and the color figure matrix, authenticity of the two dimension code being scanned; if the two are not matched with each other, the scanned two dimension code is a fake copied code. According to the color figure matrix two dimension code, the color figure matrix is printed on the side of the two dimension pattern, and a color sequence of the color figure matrix is obtained via a color sequence algorithm; thus via one known two dimension code, the pattern and the color figure matrix of another two dimension code cannot be deduced; a problem that the two dimension code is copied in bulk and authenticity thereof is impossible to tell can be solved.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code anti-counterfeiting, and relates to a color digital matrix two-dimensional code, in particular to a color digital matrix two-dimensional code and an anti-counterfeiting method thereof. Background technique [0002] A two-dimensional code is a pattern of bars and spaces distributed on a plane according to certain rules to record data symbol information with a specific geometric figure. QR codes have the advantages of high reliability (reading accuracy far exceeds manual records), high efficiency (very fast reading speed, equivalent to 40 characters per second), etc. [0003] Wherein, the QR Code bar code is a kind of matrix two-dimensional bar code (the two-dimensional code referred to in the present invention is the QR Code bar code) developed by Japan Eenso Company, such as figure 1 As shown, in addition to the large information capacity and high reliability of two-dimensional barco...
