AmBox: Device-to-Blockchain Ambient Sensing for Food Traceability
🤖 AI Summary
This study addresses the lack of data integrity and trustworthiness in environmental monitoring within food supply chains, which hinders effective traceability. To overcome this challenge, the authors propose AmBox, a novel system featuring a lightweight intermediary architecture that directly connects sensing devices to a blockchain network. Specifically, temperature and humidity sensors—implemented on Raspberry Pi and ESP32 platforms—are integrated directly into a Hyperledger Fabric network. The system dynamically manages device activation, deactivation, and identity authentication based on business context, ensuring that environmental data is trustworthy at the source, tamper-resistant, and fully traceable. Prototype evaluation demonstrates that AmBox reliably and efficiently records environmental data on-chain, significantly enhancing transparency and mutual trust among supply chain participants.

📝 Abstract
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.
