Multi-Layer Token Framework for Data Protection in Cloud Computing

Abstract

Cloud Computing (CC) is paradigm shift that is evolving to support new scale of automation dimensions in computing, networking, and storage. It has drawn rising attention in the fields of Internet of Things (IoT), medics, banking, machine learning and weather prediction. Cloud computing provides access to lot of computing resources including infrastructure, hardware, network, server and applications services to its users. These services are controlled by third party known as Cloud Service Providers (CSP).  Despite the flexibility and scalability of the cloud computing which has given the business a tremendous revolution, security is of paramount importance. In this paper, we propose a framework based on three levels of authentication. According to the framework, we introduce authorization level, privacy level, and verification level. Moreover, different types of services provided by cloud service providers, types of clouds, drawbacks of cloud computing, challenges, security ricks, privacy issues, data storage issues and principles of data security are also discussed. The main focus of the paper is the protection and sensitivity of private data, the privacy of data, implementation of the proposed framework and its architecture verification.
