Techniques and protocols for enhancing data privacy in cloud computing: A review

The emergence of cloud computing has enabled millions of devices across the globe to communicate and exchange massive amounts of data that is classified as private with each other. Given that these devices and platforms are scattered in different geographical areas, communicating with IoTs all the time, the issue of data security, in particular, assurance of data privacy has arisen. Several attempts in mitigating this issue has been by both academic and industry researchers in terms of technology, practices and protocols but it still remains a serious challenge even as cloud computing forges into the future. As a result, both individuals and organizations whose private data are held in the cloud are getting jittery due to the frequent data compromise or exposure in the cloud servers. This paper reviews the various challenges in data privacy and the mechanisms and techniques proposed by various researchers in bid to mitigate them and create a trustworthy cloud environment. It undertakes a comparative research analysis of the existing research work on data privacy protection techniques that have been proposed and implemented in the cloud computing environment.
