Anti-counterfeit system for agricultural product origin labeling based on GPS data and encrypted Chinese-sensible Code

摘要

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 10 m scope and unique identification information about the origin of agricultural products and achieved the aim of developing an anti-counterfeiting system
