Problems solved by technology

[0005] However, in the existing two-dimensional code anti-counterfeiting technology, when data is created, the anti-counterfeiting features need to be photographed in advance, and then the data is uploaded to the network server for use.
This method not only requires a large amount of engineering to establish the database, but also is prone to errors in the process of establishing the database. In order to minimize the occurrence of errors, careful proofreading must be carried out in advance. cost

Embodiment 1

[0051] See figure 1 , figure 1 It is an anti-counterfeiting identification method based on two-dimensional codes of the present invention. In the first step, the control center of the digital printing machine uses a random code-changing program to generate anti-counterfeiting characteristic data of letter strings, number strings or character strings composed of letters and numbers. And the anti-counterfeiting feature data has randomly changing colors; as figure 2 As shown, it is a series of numbers 11 with different colors generated by the random code change program. The content is 123456789, and the colors of each number are different. Since this series of numbers is randomly generated, it has strong anti-counterfeiting properties. image 3 and figure 2 Similar, the difference is a string of letters 13 of different colors generated by the random code change program, and its content is WTHWTUYOU; Figure 4 and figure 2 Similar, the difference is a string 14 of numbers a...

Embodiment 2

[0070] Embodiment 2 (not drawn)

[0071] The present invention also provides an anti-counterfeiting identification method based on two-dimensional codes. The core of this method is to directly use the color of the colored two-dimensional code and the unique graphic structure of the colored two-dimensional code to perform anti-counterfeiting. It only needs to compare the color codes stored in the database. Whether the two-dimensional code is the same as the color two-dimensional code printed on the substrate can achieve the purpose of anti-counterfeiting. This method has the advantage of being simpler and faster. The specific method is:

[0072] In the control center of the digital printing machine, a random code-changing program is used to generate a string of letters, a string of numbers or a string composed of letters and numbers; the string of letters, strings of numbers or strings here can be arbitrary;

[0073] Use a two-dimensional code generator to convert one of the g...

Abstract

The invention discloses a bidimensional-barcode-based anti-counterfeiting identification method and a bidimensional-barcode-based anti-counterfeiting identification system. One method comprises the following steps of: randomly generating anti-counterfeiting feature data with random color change, and converting a file name of the anti-counterfeiting feature data and information which at least comprises an enterprise website into bidimensional barcodes; respectively printing the anti-counterfeiting feature data and the bidimensional barcodes on printing bearing objects; uploading a database consisting of the anti-counterfeiting feature data to a network server; shooting the bidimensional barcodes on the printing bearing objects by a mobile terminal with a camera, and decoding the barcodes; automatically surfing on the Internet according to the enterprise website, and finding the anti-counterfeiting feature data associated with the bidimensional barcodes according to the file name; downloading the anti-counterfeiting feature data to the mobile terminal; and judging whether the downloaded anti-counterfeiting feature data are the same as the printed anti-counterfeiting feature data, if so, determining that the anti-counterfeiting feature data are true, and otherwise, determining that the anti-counterfeiting feature data are artificial. By the method, the database does not make mistakes; a process for shooting an anti-counterfeiting feature or a color bidimensional barcode in advance and then making the database is not needed, so that the manufacturing cost is low; and the anti-counterfeiting judgment is simple and accurate.

Description

technical field [0001] The invention relates to a digital anti-counterfeiting method and system, in particular to a two-dimensional code-based anti-counterfeiting identification method and system. Background technique [0002] Two-dimensional barcode / two-dimensional code (dimensional barcode) records data symbol information with a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules; The concept of "0" and "1" bit streams based on the internal logic of the computer uses several geometric shapes corresponding to binary to represent text and numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment to realize automatic processing of information : It has some common features of barcode technology: each code system has its specific character set; each character occupies a certain width; it has certain verification functions, etc. At the same time, it also has the charact...
