Counterfeit invisible general commodity bar code or dot matrix and checking method by using mobile phone

Abstract

The invention relates to a counterfeit invisible general commodity bar code or dot matrix and a checking method by using a mobile phone. A group of colored bar codes or dot matrixes are decomposed and arrayed on a micro-lens focus plane in a range of optical blind spots pre-calculated by the angle relative to a micro-lens optical axis and a watch distance by using the optical function of a micro-optical lenticulation counterfeit mark, so that the optical function of the micro-lens can ensure that invisible colored bar codes cannot be seen in a general watch distance. During checking, the mark is photographed in a micro distance by using the mobile phone with the function of photographing; and since the optical projection angle is changed, a lens of a camera can be used for recombining and displaying the decomposed colored bar codes on a screen, and a consumer can check the truth of commodities by contrasting colored reference bar codes of the commodities. Meanwhile, the consumer can transmit pictures of the colored bar codes back to an established counterfeit control center for checking; and a server of the counterfeit center can automatically search and check the counterfeit of products after receiving the bar codes of the mobile phone and querying and transmitting relevant data of the products to the mobile phone in real time.

Description

technical field [0001] The invention relates to an international common commodity bar code including multiple anti-counterfeiting features and safety functions, in particular to an anti-counterfeiting invisible general commodity bar code or dot matrix and a checking method by using a mobile phone. Background technique [0002] Counterfeiting is an old problem. There are counterfeit products, but it is unbelievable. Despite the development of advanced technology in all aspects today, a simple and effective anti-counterfeiting method has not yet been invented. Although there are all kinds of so-called anti-counterfeiting marks manufactured by different technologies on the market, all of them are in name only and have no anti-counterfeiting effect. The main reasons are: [0003] (1) The general consumer does not know how to distinguish the authenticity. Is the anti-counterfeit mark affixed on the product real or fake? Unable to check. [0004] (2) The current anti-counterfeit...

AI Technical Summary

Problems solved by technology

[0003] (1) The general consumer does not know how to distinguish the authenticity. Is the anti-counterfeit mark affixed on the product real or fake? Unable to check

[0004] (2) The current anti-counterfeiting marks can be forged

[0005] (3) Other anti-counterfeiting methods that must use special spectra, biochemical reactions, and electronic messages, which cannot be identified by ordinary consumers on the spot and require law enforcement personnel to check with special devices, which is inconvenient and impractical
