Abstract

A method for anti-counterfeit inspection of a QR code of an agricultural product based on a watermark library. The method includes establishing a watermark-containing QR code library; tracing a QR code watermark image; and verifying the QR code watermark image. Watermark-containing QR codes are generated by a QR code generation module and a watermark library, and the watermark-containing QR codes are constructed as the watermark-containing QR code library. The watermark-containing QR code library is used to verify the QR code watermark image, and the QR code watermark image is obtained by tracing the watermark-containing QR codes. In the method for anti-counterfeit inspection of a QR code of an agricultural product based on a watermark library, an image watermark library is designed, so that the embedding of a watermark is no longer single.
