A Study on Effective Methods for Ensuring Privacy in Cloud Computing Environment

摘要

Cloud computing has grown as a network based service oriented computing model. Cloud computing allows users to access computers and software applications hosted by remote servers. While providing access to such data we must keep in mind the privacy of the data stored in such remote machines or servers. Thus there arises a need for protecting the privacy of the data. There arises a serious concern in privacy when the data is stored and shared over the distributed databases. Relinquishing the control over data and application poses challenges of security, performance, availability and privacy. The critical factors to consider for the wide utilization of cloud computing environment are confidentiality, authentication, integrity and non-repudiation. A major concern is that the user may download a malware or a virus that steals user data and spreads across the entire cloud network. If such attacks are possible then it the integrity and confidentiality of the data will be lost. In this paper we provide a study on the various privacy issues related to cloud computing.
