Anti-fake hidden universal commodity bar code or dot matrix and checking method by using mobile phone

Technical Field

The present invention relates to a universal commodity bar code including several anti-fake features and safety functions, in particular, it relates to an anti-fake invisible universal commodity bar code or dot matrix and its checking method by using mobile telephone.

Background

Counterfeiting is an ancient problem, and the existing commodities have counterfeiting, but the counterfeiting is difficult to be trusted, and although the advanced technologies in all aspects today are developed, a simple and effective anti-counterfeiting method cannot be invented. Although various anti-counterfeiting marks manufactured by applying different technologies are available in the market at present, all the anti-counterfeiting marks have names and real properties and do not have any anti-counterfeiting effect, and the main reasons are as follows:

(1) the general consumers do not know how to distinguish between true and false, and is the anti-counterfeiting mark attached to the goods true or false? It cannot be checked.

(2) The current anti-counterfeiting mark can be counterfeited.

(3) Other anti-counterfeiting methods which need to adopt special spectrum, biochemical reaction and electronic information cannot be identified in the field by general consumers, so that law enforcement personnel need to check the anti-counterfeiting method by using special devices, and the method is inconvenient and impractical.

Disclosure of Invention

The invention aims to provide an international universal commodity bar code comprising various anti-counterfeiting features and a safety function.

The present invention has the advantages that the common consumers can easily check and identify the false or true of the anti-fake mark and the product, and the other advantage is that the users only need to use the mobile phone with the function of photography and the related software to shoot the invisible bar code on the product for checking on the internet.

Effective and practical

The commodity in all parts of the world can be pasted with anti-fake marks of invisible commodity bar codes or the bar codes can be printed on the commodity, the invisible bar codes on the marks or on the commodity can be shot down by using a mobile phone with camera function and related software, the network can be accessed, the anti-fake center can check in real time and send the result and the data of the commodity back to the mobile phone, the invisible universal commodity bar codes can be globalized, and the existing communication network can be used for forming a global anti-fake control network.

Anti-counterfeiting function

(1) The color bar code of the commodity is optically decomposed and arranged on the focusing plane of the micro lens at the optical blind spot of the relevant angle of the optical axis of different lenses, and the invisible bar code can not be seen from the surface of the mark at the general and customary viewing distance and range.

(2) The color bar code on the mark is composed of ultra-high resolution micro-pixels and is arranged in a high-precision error-free format, which can not be realized by any printing method and cannot be imitated.

The invention provides an anti-counterfeiting mark and a product of an anti-counterfeiting invisible general commodity bar code manufactured by utilizing a micro-optical lens grating material, wherein a color bar code is decomposed by applying the optical function of a micro-lens, an optical blind spot pre-calculated at the angle related to the optical axis of the lens and the viewing distance is hidden on a focusing plane of the micro-lens, the invisible bar code cannot be seen on the surface of the mark in the general viewing distance range due to the optical function of the micro-lens, a mobile phone with a photographing function is used for photographing at the micro-distance of the mark during checking, the lens of a camera can recombine and display the decomposed color bar code on a screen due to the change of the optical projection angle, and a consumer can check the authenticity of the commodity by contrasting the color reference bar code on the commodity.

Meanwhile, the consumer can transmit the picture of the color bar code back to the established anti-counterfeiting control center for checking, and after receiving the mobile phone bar code query, the server of the anti-counterfeiting center can automatically search and check the authenticity of the product and transmit the authenticity of the product and related data of the product back to the mobile phone in real time.

In the future, each kind of products can be printed with special anti-counterfeiting invisible bar codes, the same reference bar codes and decoding data are simultaneously stored in a database of an anti-counterfeiting control center, a user only needs to take a picture of the anti-counterfeiting products at a micro distance by using a mobile phone with a camera function and relevant software installation and then transmits the picture to the center for checking, and relevant results and other data of the products are transmitted back to the mobile phone in real time. If the person is found to be a counterfeit, the central person can talk to the owner and inform the local customs enforcement officer to follow up the person for the first time.

The surface of the sign is a micro-optical lens grating, the bottom layer is a colored photosensitive film, and a reflective film is arranged under the photosensitive film.

The colour barcode on the sign is imaged in optical projection through the lens optical axis onto the photosensitive film.

The number, arrangement order and format, color, shape and size of the colored commodity bar codes on the sign are not limited.

The color bar code on the symbol represents a number, a letter, or a name.

The decomposed image of the color barcode on the mark is arranged in a set position where the angle formed by the photosensitive film with the optical axis of the lens and the viewing distance is calculated in advance.
