Controlling Access with Multi-Authority and Identification for Individual Personal Medical Records

Abstract

A useful health tool that helps both patients and doctors is the personal healthcare record (PHR) system. A semi-trusted provider of cloud services frequently manages and stores a PHR. Confidential health information could still be viewed by unauthorized people and unscrupulous parties, though this possibility is still present. By providing a client-centric PHR sharing framework, this technique safeguards patient privacy and guarantees that patients retain control over their PHRs. Prior The PHRs in this architecture have been multi-authority protected against outsourcing. attribute-based encryption, which solves the issue of key hosting and provides PHRs with fine-grained access control.
