With the increased attention given to geographical labeling and the increased awareness of enterprise brands in many countries, anti-counterfeit systems for identifying the origin of agricultural products are important for limiting the production of fake goods and improving the competitiveness of agricultural products. An anti-counterfeit system for identifying the origin of agricultural products based on GPS and encrypted Chinese-sensible Code was designed. The anti-counterfeit system used the LPC1768 microprocessor of the Coretex-M3 series as its core controller, and the system was programmed with the C language. The system could collect and process the weight and location of the agricultural products, encrypt and encode the Chinese-sensible Code based on an AES (Advanced Encryption Standard) algorithm with a different cipher each time, and then print the anti-counterfeit label. The application results showed that the system runs reliably and stably, 98% anti-counterfeit labels were correctly identified and used to trace the origin of the products. Additionally, the system accomplished the task of providing precise positioning and location accuracy is about 10m scope and unique identification information about the origin of agricultural products and achieved the aim of developing an anti-counterfeiting system.
