AmBox: Device-to-Blockchain Ambient Sensing for Food Traceability
For food supply chain stakeholders, AmBox addresses the challenge of ensuring data integrity in ambient monitoring, but the solution is incremental, combining existing blockchain and IoT technologies.
AmBox enables device-to-blockchain ambient sensing for food traceability, ensuring secure and tamper-resistant data collection. A prototype using Raspberry Pi and ESP32 records sensor data on Hyperledger Fabric, providing timely and reliable data to increase transparency and trust among supply chain stakeholders.
From production to consumption, ensuring food quality and traceability depends on reliable monitoring of environmental conditions across the supply chain. Ambient sensing devices can collect relevant data such as temperature and humidity, but ensuring its integrity among stakeholders remains a challenge. This work presents AmBox, a system that enables device-to-blockchain ambient sensing for food traceability. AmBox connects sensors to a blockchain, ensuring secure, verifiable, and tamper-resistant data collection with minimal intermediaries. It manages sensor commissioning and operation with the adequate business context. AmBox can operate with standalone nodes or within a distributed node-mote architecture, allowing flexible deployment at different points along the supply chain. A prototype using Raspberry Pi and ESP32 hardware can record sensor data directly on Hyperledger Fabric. Experimental results show that AmBox provides timely and reliable data that can increase transparency and trust between the supply chain stakeholders.
