Description
Technical Field
The application relates to the technical field of anti-counterfeiting marks, in particular to a three-dimensional anti-counterfeiting mark and an anti-counterfeiting method thereof.
Background
The anti-fake mark is one kind of anti-fake label capable of being adhered, printed and transferred to the surface of the mark, the package of the mark or the attachment of the mark, and has anti-fake effect. The anti-counterfeiting characteristic of the anti-counterfeiting marker and the identification method are souls of the anti-counterfeiting marker, and the anti-counterfeiting is a measure for preventing the actions of imitation or copying for deception and without permission of an owner. However, the existing anti-counterfeiting marker has the problems of single anti-counterfeiting means, limited information carrying capacity, incapability of realizing information network anti-counterfeiting verification and the like.
The current anti-counterfeiting mark has more imitation and counterfeiting events, and the main reasons are that the specificity of the existing anti-counterfeiting mark is poor and the imitation difficulty is low. The current plane anti-counterfeiting mark is mainly used for anti-counterfeiting by adopting an encrypted holographic image mode, but is limited by the two-dimensional characteristics and has limited encryption effect. The encrypted holographic image is an invisible or speckle encrypted image obtained by encrypting the anti-counterfeiting image by adopting an optical image coding encryption technology such as laser reading, optical micro-lithography, low-frequency lithography, random interference fringes, moire fringes and the like, and mainly comprises the following steps: 1. laser reading, using optical conjugate principle to store the character or image information in the holographic image, under the general environment, these information can not be displayed, when using laser pen to irradiate, people can use sulfuric acid paper or white paper to see the stored information, the stored information can be character, mark, gray image, even an article, its expression form also has two kinds of reflection type and transmission type; 2. optical micro-shrinkage, in which text information is recorded on a hologram in an optical micro-shrinkage mode and is difficult to be recognized by naked eyes in general, and specific contents can be observed under a magnifying lens of 10 times or even 100 times, generally, Chinese can be reduced to 0.1mm, and English can be reduced to 0.05 mm; 3. low-frequency photoetching, directly recording the pre-designed fringe patterns on the hologram in a micro form in a non-interference way, wherein the fringe density of the patterns is about 100 lines/mm which is 10 times lower than that of the common interference fringes, the visual effect is that some parts on the hologram have diffraction patterns similar to metallic luster, and if the fringe patterns are computer-generated holograms, the information can be reproduced by laser; 4. random interference fringes, a random mechanism is introduced when a hologram is manufactured, random interference patterns are recorded on the hologram, the patterns have obvious characteristics and are not repeatable, even if the patterns generated by the same person at different moments by using the same process are different, the patterns are a good anti-counterfeiting mode, besides static plane interference fringes, dynamic and three-dimensional interference fringes are developed at present, and the copying difficulty of counterfeiters is high; 5. moire interference encryption utilizes the Moire principle, i.e. the principle that two sets of periodic structure fringes are overlapped to generate a third set of periodic structure patterns, wherein the phase of one set of fringes is changed and a pattern is coded, the pattern is hidden and can not be distinguished at ordinary times, and the pattern is displayed when the pattern is overlapped with the other set of periodic structure fringes.
The existing encryption holographic image anti-counterfeiting technology has a certain anti-counterfeiting function because the existing encryption holographic image anti-counterfeiting technology cannot be seen through naked eyes or only shows a piece of noise light, if the existing encryption holographic image anti-counterfeiting technology is not provided with a secret key, the secret key is difficult to decipher. However, the existing encryption method has the disadvantages that the existing encryption method basically aims at the anti-counterfeiting design and verification of the outer package of the product, and information characteristics such as the weight, the production place, the production time and the like of the product are not included, so that multiple information verification of the product cannot be realized, the anti-counterfeiting information cannot be recorded and stored in an anti-counterfeiting query system on the internet, and if an anti-counterfeiting marker does not form a uniquely determined corresponding relationship with the actual product and the authenticity of the product is verified through the verification query system, the anti-counterfeiting performance of the anti-counterfeiting marker can be greatly reduced.
