Embodiment 1

[0049] refer to Figure 1-Figure 9 Shown, document 10 of the present invention comprises credit card, passport, or any important document, or important and the document that can not be duplicated without permission, there is a place to store security shape 12 on document 10 surface, and this document 10 actually puts a After removing the lid 18 of the glass bottle 14, the small and thin tubular tool 22 is put into image 3 In the shown glass bottle 14, and immerse in the liquid 16 of volatile liquid or liquid paste with alcohol etc., contain a quantity mark 20 in the liquid 16, typically, the lid 18 of this glass bottle 14 is plugged and shaken, makes very The marks 20 like sand grains are slightly evenly dispersed in the liquid 18. When the marks 20 are evenly dispersed in the liquid 16, the thin tubular tool 22 part of the cap 18 is removed and penetrated into the liquid 16. The tool 22 is inserted into the liquid 16. Figure 4 As shown, then the tubular tool 22 is taken ou...

Embodiment 2

[0057] refer to Figure 10-Figure 12 Shown is a second manufacturing method of the present invention using the same base layer 24. A photosensitive layer 32 is applied to the base layer 24. This photosensitive layer 32 is photographically exposed to light to produce an uneven surface, as a result of which the structured layer 34 is disposed. 24 in the base layer, while having different heights, such as Figure 11 As shown, the edge of the construction layer 34 will come off, as Figure 12 As shown, the photosensitive layer 32 is then melted, leaving only the tiny markings 20, while the other elements of the structured layer 34 are shown.

Embodiment 3

[0059] refer to Figure 13-Figure 15 Shown is a third method of making indicia 20 according to the present invention, wherein a seed layer 36 is applied to the base layer 24, and a photosensitive layer 38 is applied to the seed layer 36, and the photosensitive layer 38 is patterned by photographic exposure. , and then make a structure layer 40 in the ditch 42 in the photosensitive layer 38, then melt the seed layer 36 and the photosensitive layer 38, leaving only the structure layer 40 containing the mark 20, after other marks are collected, put back into the previous 14 glass bottles.

Abstract

An anti-fake mark composed of a plurality of minute markers or patterns and forming method thereof to identify an article whether a forgery and prevent forgery. The method for identifying the article includes forming at least one unique mark comprising a plurality of minute markers or patterns, which is randomly dispersed in the mark. The invention has a advantage of preventing forgery of an article by a forger as well as easily identifying and comparing.

Description

technical field [0001] The present invention relates to the recognition system and recognition method of related objects, in particular to an anti-counterfeit mark containing many tiny marks or patterns and its forming method. As the basis for identifying and verifying the authenticity of the object. Background technique [0002] As is well known, there are many methods for authenticating the authenticity of an object and anti-counterfeiting techniques. For example, anti-counterfeiting technologies such as laser three-dimensional portraits, watermarks, special fluorescent ink printing, and color-preserving fibers. [0003] There are three important criteria for evaluating anti-counterfeiting technologies and identification methods: [0004] The first is that the availability of raw materials and the resource control of manufacturing equipment make it difficult for manufacturers to obtain the materials and equipment needed for counterfeit products to provide the first layer...
