Design of Dual Code Traceability System for Agricultural Products Based on RSA Algorithm

With the rapid development of China’s economy, QR code has achieved good development as a new technology, and many merchants have begun to use QR code technology to sell, adulterate, and fabricate agricultural products. The agricultural product traceability and anti-counterfeiting system is based on internet technology and utilizes relevant computer programming software to establish traceability archives, including the traceability code, product name, affiliated distributor, and detailed introduction of the agricultural product, for the convenience of consumers’ inquiry and supervision. In terms of anti-counterfeiting technology, due to its ease of imitation and forgery, manufacturers need to invest heavily in the development of this technology, and there are drawbacks such as difficulty in detection and lack of uniqueness. In response to the above issues, this article proposes a dual code traceability system for agricultural products based on RSA algorithm. The experimental results indicate that the system not only achieves systematic management and monitoring of the production, processing, and transportation of fruit and vegetable agricultural products, but also achieves product traceability and anti-counterfeiting by encrypting product information QR codes.
