According to Dan and Anna [11] Cloud computing provides highly scalable resources accessed via Internet. since cloud computing is growing quickly day by day used by individuals and companies throughout the world, data protection problems in the cloud computing have not been tackled currently. In the cloud, users of cloud services have serious threat of losing confidential data. To address data privacy issues of users, they have proposed data protection framework. According to them the proposed data protection framework addresses the challenges throughout the cloud services life cycle. Their proposed framework comprises of three key components: policy ranking, policy integration and policy enforcement. For each component, they have presented various models and analyzed properties of each component. This paper includes a discussion on general guidelines for weighing up designed systems based on such kind of framework. They have also presented several data protection models and defined cost functions. The proposed model is shown in figure 3[11]
