The E-health clouds generate an enormous amount of data driven from PHR's, EHR's, EMR's, patient care, compliance and regulatory requirements. To preserve the privacy and confidentiality of the e-health data at untrusted servers various solutions on symmetric key-based access control has aroused. But the major drawback of these techniques is that it is patient centric and do not provide security and fine-grained access control. To solve these issues the paper defines a secure access control

As the data stored at the cloud server is highly confidential first a three-factor mutual authentication is made between the cloud server and the data user. Further, the proposed technique makes use of Attribute based searchable encryption with trapdoor function that prevents unauthorised access to the cloud data in an efficient way. The experiment is conducted using charm crypto and the results show that the proposed system provides comparatively better results than the existing techniques.
