Privacy-preserving COVID-19 contact tracing solution based on blockchain
TL;DR: Wang et al. as discussed by the authors proposed a combination of non-interactive zero-knowledge proof and multi-signature with public key aggregation to preserve the full-fledged privacy protection property with a lower computational cost.
Journal ArticleDOI
A blockchain-based secure storage scheme for medical information
TL;DR: Wang et al. as discussed by the authors proposed a healthcare information security storage solution based on hyperledger fabric and the attribute-based access control framework, which allows dynamic and fine-grained access to medical information and then stores the medical information in the blockchain, which can be secured and tamper-proof by formulating corresponding smart contracts.

Modeling and analysis of port supply chain system based on Fabric blockchain
TL;DR: In this article , a port supply chain system based on Fabric blockchain (Fabric-PSChain) is designed and implemented, where four smart contracts are developed by taking advantage of the blockchain's decentralized, tamper-free, distributed consensus, combined with the Role-Based Access Control Policy (RBACP), realizing the functions of access control policy formulation, enterprise list query, cargo order uploading, and order query.
