Abstract:-Â In this article, we describe a brand-new, secure EHR sharing system built on cloud computing and blockchain technology, with verified data integrity. With the aim of addressing data security and the loss of control rights during personal health record exchange, the new system uses symmetric encryption and attribute-based encryption approaches to enable privacy protection and fine-grained access restrictions. Comparatively to existing systems, the new strategy enables patients to give private key attributes to users, eliminating a number of security issues. Additionally, the new scheme manages scheme keys via the blockchain. The original method further enhances the efficacy of information reliability confirmation by storing the linked file set in a clever agreement together with the hash benefits of encoded individual health data on the blockchain.
Keywords:-Â blockchain, cloud computing, data integrity, Data security.
