An Enhanced Auditability and secured privacy preserving Approaches for Cloud Assisted Mobile Access of Health Data

Abstract

This technique is developed with the intention of privacy issues in the current cloud data storage, curbing the
adoption of electronic healthcare systems and the wild success of cloud service models, this propose to build privacy into
mobile healthcare Systems with the help of the private cloud. This system offers salient features including efficient key
management, privacy-preserving data storage, and retrieval, especially for retrieval at emergencies, and auditability for
misusing health data. Precisely, this propose to integrate key management from pseudorandom number generator for unlink
capability, a secure indexing method for privacy maintaining keyword search which hides both search and access
configurations established on redundancy, and integrate the concept of attribute-based encryption with threshold
authorization for providing role-based access control with auditability to avoid potential misbehavior, in both normal and
emergency cases.
