Security and Privacy Issues within the Cloud Computing

Cloud Computing has been regarded as evolutionary paradigm recently. It has much strength, such as large storage, ubiquitous network access, cost effective and so on. However it also faces security and privacy concerns. In this paper, we discussed several major security and privacy issues. And we also proposed four effective methods to handle such issues. According to the features of issues, we investigated the feasible solutions and finally found four methods. Such methods can be applied to the generalized Cloud Computing. This paper is original that we consider the characteristics of Cloud Computing adequately, so the methods are well functioned and can be developed further to solve other problems.
