摘要：
Blockchain technology is an emerging technology, it has the characteristics of anti-tampering, decentralization, and distributed storage. It can effectively solve the problems of privacy security, insufficient user control rights, and single point failure in the existing data sharing model. This paper takes electronic health record (EHR) sharing as an example and proposes a data sharing access control model based on smart contract with integrated credit evaluation to provide patients with a trusted EHR sharing environment and dynamic access control policy interface. Experiments show that the proposed model effectively solves the problems of patient privacy security and insufficient control of EHR. At the same time, the characteristics, safety and performance of the model are analyzed. Copyright © 2021 Acta Automatica Sinica. All rights reserved.
