A Review on Privacy Preservation in Cloud Computing and Recent Trends

Cloud computing is a distributed computing architectural model that offers on-demand computing services via the Internet. It includes servers, computing resources, applications, data storage, development tools, etc. However, despite the different services and benefits offered by the cloud, security and privacy are the primary hindrances for organizations for opting cloud. The real benefit of the cloud can be only enjoyed if the sensitive data kept in the database can be secured from unauthorized access. Privacy preservation in cloud computing is nothing but hiding sensitive data, where the data is stored in the software and databases scattered around the Internet. Various methods have been put forward by researchers to preserve privacy in cloud computing over the past few years.
