Cloud computing allows data and services to be placed in a pool of resources. The clients are able to access the resources of the cloud through service providers. The flow of these resources takes place through a common channel i.e. internet. The common channel makes it vulnerable to attacks. These attacks result in the privacy issues thus decreasing the level of trust of the customer on the cloud service provider. There are several solutions to solve these privacy related problems. In this paper, the authors will describe cloud computing architecture and several methods to solve the privacy issues. They have analyzed each proposed solution with their pros and cons.
