Enhanced access control system for data security in cloud environment

Abstract

The cloud uses the technique of web services with the consent of Service Oriented Architecture (SOA) and information exchange operator that converts information coming from a wide range of service providers into a standard data exchange pattern. In this, an interoperable information system that considers data integration and interoperability of data accessible with different service providers in heterogeneous situations. The cloud challenge lies in the extensive collections of standards and demonstration of similar data in diverse representations. This could be ruled out by presenting the method of web service technology to solve the interoperability issues in all domains. So, the proposed system supports the analysis of data, and if suitable data is present, and then the retrieval of information is happened by way of different searching techniques effectively and less time, Also it provides security to protect the data from various requesters. In the first part of the research, accessing information from the open cloud is attained effectively with the support of searching techniques and the approved access control model appears to be Role-Based Access Control (RBAC) which sets the privileges for the authorized client to retrieve the data. In this, the searching is done by the keyword searchable technique, which allows the clients to search for data through the string index by various indexing levels. Additionally, the RC4 encryption/decryption process is utilized to protect the data from unknown clients. The proposed representation can be applied in the medical field to fetch the data of similar types which allow the clinical data distribution. newline
