Blockchain-based Trust Information Storage in Crowdsourced IoT Services
This addresses trust management for IoT service providers and users, but appears incremental as it applies blockchain to a specific domain.
The paper tackled the problem of ensuring integrity and availability of trust information in crowdsourced IoT services by proposing a blockchain-based distributed storage framework with geo-scoping for fast access and space preservation, demonstrating effectiveness through experiments on real datasets.
We propose a novel distributed integrity-preserving framework for storing trust information in crowdsourced IoT environments. The integrity and availability of the trust information is paramount to ensure accurate trust assessment. Our proposed framework leverages the blockchain to build a distributed storage medium for trust-related information that ensures its integrity. We propose a geo-scoping approach, which ensures that trust-related information is only available where needed, thus, enabling fast access and storage space preservation. We conduct several experiments using real datasets to highlight the effectiveness of our framework.
