Logistics Tracings in Food Safety Emergencies Based on the RFID Technology
It is difficult to locate questionable foods in food safety emergencies, this study builds a food logistics framework from producers to retailers based on the RFID technology and designs a food logistics tracking systems, which transfers and tackles underlying data from logistics nodes. Tracking queries get IP addresses of logistics nodes from the address resolution service system by Internet. The queries are decomposed and composed to obtain and synthesize data from all the underlying data sources to trace food information for effectively tracing locations of questionable foods. The work is very important to prevent more spreads of food safety emergencies.
