Healthcare services have been seen a mamoth movement in utilization, sharing and stockpiling. Cloud computing has become a backbone for the new era of healthcare organizations. cloud computing has made it possible the movement of application from local to remote location, massive data storage. Owner can have access to centralized or decentralized data storage server, in which the data management handled by remote provider. The heterogeneous and dynamic characteristics of cloud has introduced many different security challenges. Among them access control and integrity proof are most important which incur high consideration while focused on healthcare data. Attribute based encryption is one of the access control technique which allows integration of access policies, attributes, and encrypted data. In this paper, a decentralized data access control technique with user revocation has been proposed. The integrity checking proof validates that the user data is intact and revocation mechanism will help to revoke the user in linear time. Moreover, the proposed access control and authentication schemes are decentralized and comparable to other approach.
