Tackling Grand Challenges in Food Safety: A Big Data and IoT Enabled Approach


In this project, we apply our research achievements to food safety area and tackle the critical issues including biological risks, chemical risks, and food fraud in food safety. These issues are not adequately addressed by current solutions, e.g., sampling inspection. First, although biological and chemical risks can be well detected, food status cannot be traced in a secure and authentic way to avoid food fraud. Second, the sampling inspection is conducted by human resources, which is labor-intensive and time-consuming. Third, the sampling inspection can only detect food status while it leaves unknown which part goes wrong and what the future food status will be. To tackle the above food safety issues, we develop a big data and IoT enabled system, which provides three food safety services, i.e., traceability, status detection, and risk prediction.
