Multifunctional anti-counterfeiting method for digital codes

Abstract

The invention provides a multifunctional anti-counterfeiting method for digital codes and belongs to the field of anti-counterfeiting of the digital codes. The method comprises the following steps: (1) a digital multifunctional authentication system generates and sends anti-counterfeiting digital codes and attribute character data corresponding to the anti-counterfeiting digital codes to color code-transforming printing equipment; (2) the color code-transforming printing equipment prints to generate an anti-counterfeiting mark according to the anti-counterfeiting digital codes and the attribute character data corresponding to the anti-counterfeiting digital codes, wherein the anti-counterfeiting digital codes and the attribute character data are generated in the step (1); (3) the anti-counterfeiting mark is attached to a product; (4) the anti-counterfeiting digital codes and the attribute character data corresponding to the anti-counterfeiting digital codes are sent to a data center; and (5) a consumer carries out authenticity inquiry in the data center according to the anti-counterfeiting digital codes on the anti-counterfeiting mark. A plurality of anti-counterfeiting technologies are combined, so that the method has the advantages of large difficulty in counterfeiting and strong general applicability, and can be widely applied to various products and consumers.

Description

technical field [0001] The invention relates to the field of digital anti-counterfeiting, in particular to a digital anti-counterfeiting system. Background technique [0002] The current common digital anti-counterfeiting technology is to use the principle of digital anti-counterfeiting, that is, to set a unique code for each product connected to the network, and store this code in the central database, and at the same time establish a telephone (mobile phone or network) across the country. Query the authentication network. Consumers who purchase products with digital anti-counterfeiting labels only need to make a phone call or access the Internet, and input the code on the product. The system compares the code entered by the consumer with the code in the database. If it matches and the first query will prompt as Genuine product, if it does not match, it will be suggested as counterfeit product. [0003] However, the current technology has major shortcomings. At present, t...

Problems solved by technology

[0003] However, the current technology has major shortcomings. At present, the digital production in the anti-counterfeiting industry is mostly monochrome printing fixedly divided into several sections, and the query system only judges whether the input number is consistent with the data in the database.

Even color printing is also a printing with uniform color change rules, and it is still easy to counterfeit. Even if some manufacturers can achieve organic color changes, there are still great defects in anti-counterfeiting only with color codes, such as color blind or color weak consumers.
