PRIVACY ENHANCEMENT IN CLOUD ENVIRONMENT THROUGH TRUSTED THIRD PARTY APPROACH

Abstract

Cloud computing is an established approach in the current IT industry which provides web-based services, computations, and storage facilities to the end-users including business, healthcare, and government institutions. It offers dynamically scalable resources, on-demand services through which the customers are economically benefited by availing any of the resources and services. In the traditional way of cloud computing there is a possibility for the cloud service providers(CSP) to view, access, modify, and monitor the utilized resources of the cloud customers thus the privacy is a major concern for a cloud customers(CC), especially when sensitive data such as personal profile, financial records, medical reports, etc. are outsourced to the cloud server. In this paper, a model is proposed to support primarily the privacy issues of the customers and providers by incorporating the concept of the trusted third party(TTP) that can manage the computing process held on between CC and CSP without revealing their identities to each other. The trusted third party is an autonomous system that facilitates secure communication between the two parties and it ensures a customer to have high-level of trust on cloud providers by guarantying the privacy protection of the data.
