This paper presents a new design approach for Access Control services leveraging smart contracts provided by blockchain technology. The key idea of our proposal is to codify Access Control policies as executable smart contracts on a blockchain. This transforms the policy evaluation process into ...

Blockchain-based access control system, in spite of providing confidentiality to the data, also ensures the integrity of the same. Blockchain technology is tamper-proof by its default implementation and access control increases the security of the data stored in the devices. 展开 ...
Here, patient data stored on external storage that is collected by retraining SDA algorithm are securely accessed using blockchain based access control manager in real-time. A scenario of blockchain based secure access control on ML data has been represented in Fig. 12. 这个是研究区块链在CNN网络...
They help to simplify the healthcare providers’ work-flow by providing an access to evidence-based tools and practices to improve patient’s care services. Indeed, the core feature of EHRs for healthcare providers is to create and manage the digital format of health information, which can be...
Also, IoT system needs to be autonomous(自动运行) so that it can learn from the gathered data and make context-based decisions [4]. In such an environment, machine learning (ML) can be an effective tool in understanding the patterns, analyzing, processing, and making intelligent decisions. ...

We have also designed and integrated a smart contract based fine-grained access control policy to ensure that only data owners will have full control over their health data. The experimental outcomes show that the proposed model achieves good throughput and incurs a very low overhead in terms of...
identify requirements for the design of an access control suitable for the ecosystem. These requirements are imposed by the nature of the medical data as well as by the newly introduced potentials of Internet of Medical Things (IoMT) devices. As a result, an attribute-based access control ...
