摘要
To solve the problems of large-scale data storage and reliable access control in blockchain-based collaborative business process executions with multiple participants and internet of things (IoT) devices, an innovative framework is proposed. It introduces inter-planetary file system (i.e., IPFS) to achieve off-chain storage to alleviate the cost of data storage on the chain. Meanwhile, it combines task-attribute-based access control models with smart contract technology (i.e., TABAC-SC) to support traceable, fine-grained, and dynamic data access control. A real case from hearing aid company verifies the feasibility and effectiveness of the framework in data sharing and access control during the execution of collaborative business processes. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2023.
