Hidden information grating unlocking anti-counterfeiting method and system

Abstract

The invention belongs to the field of anti-counterfeiting technology for products, and provides a hidden information grating unlocking anti-counterfeiting method and a system. The hidden information grating unlocking anti-counterfeiting method can be directly implemented by means of normal printing (lithographic offset printing, flexographic printing, intaglio printing, metal lithographic offset printing, silk screen printing and digital printing), can be used for printing on surfaces of any printed materials (such as paper, paperboards, plastic films, tinplates and the like), no production costs are added, hidden images and texts only can be detected by a special grating unlocking film, a graph of anti-counterfeiting content of a product is hidden by grating anti-counterfeiting technology, hidden patterns are displayed via the grating unlocking film, high invisibility and security are realized, the hidden images and texts cannot be reprinted by means of enlarging, scanning or copying, otherwise hidden information can be lost, scanning and preprinting preventive functions are powerful, counterfeit and shoddy products can be stopped against entering markets from the sources, the hidden information grating unlocking anti-counterfeiting method brings great convenience for enterprises to crack down on fake products and maintain benefits of consumers, and the technological content of products of packaging and printing enterprises can be increased.

Description

technical field [0001] The invention belongs to the technical field of product anti-counterfeiting, and in particular relates to a method and system for unlocking and anti-counterfeiting hidden information rasters. Background technique [0002] Today, when the commodity market is prosperous and developed, new products are constantly emerging, especially brand-name products. At the same time, all kinds of fake and shoddy products are also flooding the market with an alarming speed and quantity. Therefore, we must increase anti-counterfeiting efforts to strictly prevent the harm of fake and shoddy products to enterprises and consumers. According to incomplete statistics, the current transaction volume of counterfeit and shoddy goods accounts for about 5%-6% of the total world trade, as high as 150-180 billion US dollars per year, which brings great damage to brand enterprises and brand-name products, and causes enterprises to suffer huge losses. Loss; In my country, counterfei...

Problems solved by technology

[0006] The present invention provides a method and system for unlocking and anti-counterfeiting hidden information raster, aiming at solving the problem that the existing technology has proposed the method of adding hidden information in the image and identifying it, but there are the following disadvantages: the inventions all rely on Photoshop image processing The software is manually operated and the process is complicated; it is used to encrypt the hidden information of a single image or file; there is no ready-made grating unlocking film that can be used for special screen lines, and there are only a few commonly used grating lines for plate or sheet gratings on the market The number may be provided, and the special number of lines must be produced through mold opening, and the small batch production is expensive; most of the existing patents are used to print or produce traditional film sheets, and then go to print.
