Anti-counterfeiting method and system based on high-fidelity map collection

Abstract

The invention provides an anti-counterfeiting method based on a high-fidelity hidden figure and an anti-counterfeiting system thereof, and belongs to the technical field of counterfeiting prevention. A surface figure, underlying figures and the corresponding relation thereof are analyzed by using a hidden figure print pre-printing analysis module so that concrete parameter settings are generated. Then the multilayer high-definition underlying figures are hidden by using a high-fidelity hidden figure digital net hanging module under the full-color high-quality surface figure. The high-fidelity hidden figure digital net hanging module performs image quality distortion prediction and optimization compensation for the set printing mode, plate-making printing is performed on the optimized and compensated high-fidelity halftone net figure, a high-fidelity anti-counterfeiting print is outputted, and an appropriate detection means is selected to detect the high-fidelity anti-counterfeiting print so that the anti-counterfeiting objective can be realized. According to the anti-counterfeiting method based on the high-fidelity hidden figure and the anti-counterfeiting system thereof, the quality of the surface figure can be effectively enhanced, the selection range of the surface figure can be enlarged, and the underlying figures are large in modulation amplitude, high in contrast, great in visual effect, high in resolution and wide in the range of color gradation so that the hidden figure anti-counterfeiting means is enabled to be diversified and the anti-counterfeiting performance can be effectively enhanced.

Description

Technical field: [0001] The invention relates to the field of anti-counterfeiting technology, in particular to an anti-counterfeiting method and system based on high-fidelity map collection. Background technique: [0002] Anti-counterfeiting technology refers to the technology to prevent counterfeiting and counterfeiting, and the anti-counterfeiting products made of this product have multiple anti-counterfeiting functions. First of all, it should be easy for consumers or traders without professional knowledge to identify the product through simple and elementary identification means. authenticity; secondly, it should be possible to allow the manufacturer's anti-counterfeiting personnel to identify some special information through some unconventional means; finally, when the manufacturer's anti-counterfeiting personnel cannot judge the authenticity of the product, they can use special equipment to inspect the product by professional technicians authenticity. [0003] Anti-co...

Problems solved by technology

Therefore, the application range of this technology is greatly limited

[0013] Although the existing image hiding technology has some primary applications in the field of anti-counterfeiting, due to special requirements for tables and images, and hiding images will destroy the visual effect of tables and images, and the level of image hiding technology is low, only a few layers can be hidden There are countless black and white images or texts, so it is impossible to prevent malicious counterfeiting, and it is still impossible to achieve effective anti-counterfeiting on printed matter
