The project provides a methodological framework combined with a set of tools and systems that can detect and prevent fraudulent activities throughout the food chain. The framework will improve the sustainability of food chains by increasing food safety and reducing food fraud through the WATSON systemic innovations. WATSON relies upon emerging technologies (AI, IoT, DLT, etc.) enabling transparency within supply chains developing a rigorous, traceability regime, and novel tools for rapid, non-invasive, on-the-spot analysis of food products. The results will be demonstrated in 6 use cases in various food sectors. IELab is responsible for the application of Blockchain and IoT innovations for food fraud prevention. IELab is also involved in tasks related to the assessment of methodologies, tools, and approaches for the prevention of food fraud.
