Anti-counterfeiting method

Abstract

The invention relates to an anti-counterfeiting method. The anti-counterfeiting method includes holographic anti-counterfeiting and code anti-counterfeiting. The holographic anti-counterfeiting includes two-level anti-counterfeiting; the code anti-counterfeiting includes screen codes and serial number codes; the first-level anti-counterfeiting of the holographic two-level anti-counterfeiting includes DID color switch, wide-angle animations rotating up and down along a horizontal axis, high-diffraction dynamic graphics rotating leftwards and rightwards along a vertical axis, and diffuse switch; the second-level anti-counterfeiting of the holographic two-level anti-counterfeiting includes an anti-reflection structure, rotation control, micro elements and ultraviolet printing; according to the serial number codes, secondary printing is adopted, and each holographic semi-finished product is uniquely and continuously numbered through adopting thermal dye sublimation transfer; the identity sequence ID information of each product is automatically stored in a company center database through a production management system, and therefore, management, query, statistics and tracing can be facilitated; and the database is backed up periodically, and is maintained by professionals, and therefore, data security can be ensured.

Description

【Technical Field】 [0001] The invention relates to an anti-counterfeiting technology, in particular to a holographic and coding integrated anti-counterfeiting method applied to a passport. 【Background technique】 [0002] In recent years, counterfeit banknotes, fake certificates, and counterfeit products have been abused. The anti-counterfeiting technology from the introduction to the continuous improvement has played an important role in the healthy development of the industry, and the anti-counterfeiting technology has gradually become an important independent development industry, and there has been a development of anti-counterfeiting technology. And security and anti-counterfeiting product production and service companies, applying a large number of the latest technological achievements to anti-counterfeiting practices. Anti-counterfeiting products and technologies based on product quality and safety, anti-counterfeiting and product identification have also seen huge market de...

AI Technical Summary

Problems solved by technology

[0003] At present, there is still a certain gap between domestic anti-counterfeiting technology and materials and foreign countries, mainly reflected in the relatively backward level of anti-counterfeiting technology, single anti-counterfeiting technology is not outstanding, material technology is not stable enough, research and development forces are insufficient and talents are lacking, technologies in related fields (such as materials science, optics, Chemical, biological science and information technology) comprehensive anti-counterfeiting application innovation needs to be further improved

[0004] Chinese invention patent (CN101795342A, publication date: August 4, 2010) discloses an anti-counterfeit method for screen codes based on non-printing technology, especially relates to a method for realizing anti-counterfeit screen codes based on laser engraving, including source information, code The module, embedding device, medium, extraction device and decoding module are characterized in that the embedding device is a laser engraving device, and the method includes the following steps: (1) source information encoding; (2) embedding medium; 3) Information extraction; (4) Information decoding; the advantage of this technical solution is that it carries a large amount of information and has strong anti-interference ability, but a single anti-counterfeiting can no longer meet the demand
