Distributed and Decentralized Attribute Based Access Control for Smart Health Care Data

Abstract

Most access control solutions today provide the ability for centralized authorities, whether governments, manufacturers, or service providers to gain unauthorized access to and control devices by collecting and analyzing user’s data. Data owners (DO) experience a necessity to concentrate on their own medical data and manage them. As an alternative, Blockchain promotes healthcare, including health care data, which actually may cause legal and privacy issues and solves the problem of sharing with third parties. Blockchain technology provides data owners with comprehensive, immutable records, and access to Smart Health Care (SHC) data free from service providers and websites. This paper presents a scheme, in which the data owner endorses the message based on attributes without leaking data other than the appended proof. The proposed model is Distributed and Decentralized scheme for Access Control.
