Review of Privacy Preserving Architectures in Cloud Computing

Cloud computing is a technique in which data has to be transmitted across the internet from one point to another. Since the data is free of the transmission, there is a high possibility that the data sent across may be lost or be attacked by intruders, so the privacy among the data is to be maintained for secure transmission.

Privacy in cloud computing is the ability of a user or a business to control what information they reveal about themselves over the cloud or to a cloud service provider, and the ability to control who can access that information. Numerous existing privacy laws impose the standards for the collection, maintenance, use, and disclosure of personal information that must be satisfied by cloud providers. Cloud Service Providers can store information at multiple locations or outsource it, then it is very difficult to determine, how secure it is and who has access to it.

Cloud computing is a revolutionary computing paradigm which enables flexible, on demand and low-cost usage of computing resources. Those advantages, ironically, are the causes of privacy problems, which emerge because the data owned by different users are stored in some cloud servers instead of under their own control. The privacy problem of cloud computing is yet to be solved effectively.

In this paper, I reviewed many research papers to check how many privacy preserving architectures exists and how they are preserving the data.
