An anti-counterfeit label and an identification system based on a QR code and OCR feature identification

Abstract

The invention relates to an anti-counterfeit label and an identification system based on a QR code and OCR feature identification. The anti-counterfeit label comprises an OCR feature recognition areaand a QR two-dimensional code recognition area, the OCR feature identification area adopts a matrix array conversion array to form an OCR feature identification mark, OCR is a character that can be decoded directly by the visual system, and random OCR characters are generated by a special encoding device and distributed on the OCR feature recognition area. The QR two-dimensional code recognition area is used for verifying whether the OCR is correct or not, and the OCR two-dimensional code recognition area is uniquely corresponding to the QR two-dimensional code recognition area by encrypting asequence formed by the OCR characters to form a unique corresponding ciphertext encoding. At that same time, the QR two-dimensional code identification area contains a background network interface access, and can be used for product anti-counterfeit trace. The invention has the advantages that the problem that the anti-counterfeit label is recognized by the human eye based on the QR code and thecharacteristic picture is solved, and the authenticity of the anti-counterfeit label can be automatically recognized at the same time.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeit labels, and in particular relates to an anti-counterfeit label and a recognition system based on QR code and OCR feature recognition. Background technique [0002] At present, feature anti-counterfeiting includes QR two-dimensional code and password inspection area check combined with mobile Internet online matching, QR two-dimensional code and texture feature picture correspondence, QR two-dimensional code information encryption and other means. The anti-counterfeiting scheme using OCR characters combined with QR two-dimensional code is developed from the corresponding technology of QR two-dimensional code and texture feature picture. The correspondence of the code generates the characteristic information of one object and one code. The characteristic of the anti-counterfeiting mark is that it is unique, and the anti-counterfeiting effect is relatively prominent, but the disadvantage is ...

Problems solved by technology

[0003] The existing Chinese patent document CN201610093326.2 discloses a method for anti-counterfeiting identification of measuring instrument performance information by using a two-dimensional code. It only uses two-dimensional codes for anti-counterfeiting identification and does not have the function of OCR feature identification, which is different from the solution of the present invention.
