Abstract: Structural health monitoring (SHM) systems are widely used to assess the condition of civil infrastructure. Sensor malfunctions in SHM systems may result in erroneous assessments, illuminating the need for secure archiving of malfunctions. However, methods with online functionality for secure archiving of sensor malfunctions in SHM systems have not been reported yet. This paper presents a system for secure archiving of sensor malfunctions based on blockchain technology, designed as a modular add-on for SHM systems. Using a public blockchain framework, the blockchain-based archiving system is implemented and validated for two use cases, demonstrating the potential of blockchain for SHM systems.
Keywords: blockchain technology, sensor faults, sensor malfunctions, Structural health monitoring, tamper-proof archiving
