Summary
The paper proposes a design theory (requirements, principles, and features) for a blockchain-based sensor data protection system that certifies IoT data, ensuring tamper-resistant, privacy-preserving, scalable and efficient data gathering, processing and exchange, demonstrated with the CertifiCar instantiation.
Artifact
A blockchain-based sensor data protection system (SDPS) leveraging data certification; instantiated as CertifiCar (mileage fraud prevention).
Methodology
Design science research; three iterative build cycles; ex post evaluation across mileage, pharma supply chain and energy microgrid use cases.
