Anti-counterfeiting bar code label, anti-counterfeiting bar code label information acquisition device, acquisition method, and anti-counterfeiting verification system

Abstract

The invention discloses an anti-counterfeiting bar code label, an anti-counterfeiting bar code label information acquisition device, an acquisition method, and an anti-counterfeiting verification system. By adopting a method of acquiring bar code widths of various bar units and vacant units of a label in a digitally-quantized manner, the bar code width quantized values are acquired by the anti-counterfeiting bar code label, and are used as label anti-counterfeiting identification codes. The anti-counterfeiting bar code label information acquisition device is used to read the codes of the anti-counterfeiting bar code label and the identification codes. By using the characteristics of the conventional bar codes such as simple codes, and anti-interference function and differences of bar code patterns caused by the low resolution ratio of the labels, the identification codes of the anti-counterfeiting bar code label are formed by adopting the bar code width digitally-quantized method. The identification codes are used to record the difference characteristics of the code labels, and the differences exist in different labels or the same label, and then the recognizable and unique characteristic is provided.

Description

technical field [0001] The invention relates to an anti-counterfeit barcode label, an information collector for the anti-counterfeit barcode label, a collection method and an anti-counterfeit verification system. Background technique [0002] Barcode label technology was born with the development and application of computer and information technology. It is a new technology integrating coding, printing, identification, data collection and processing. A barcode is a graphic identifier that arranges multiple black bars and blanks with different widths according to certain coding rules to express a set of information. The original purpose of the barcode is to set a unique traceable management code for each commodity, which initially involves the country's administrative management of commodity categories. Its scope of application continues to expand, involving spare parts management, inventory management, product management, extension and logistics management on the internal p...

Problems solved by technology

However, the deployment of RFID tag technology is complicated, its core technology is mastered by foreign countries, and its supply is limited. The ease of deployment and application stability need to be gradually improved. These problems hinder the popularization of RFID tag technology.

[0005] Although the technical vitality of the bar code is gradually declining, the convenience, simplicity, low cost and wide application that the bar code brings to people are beyond the reach of later technologies.
