Research on privacy protection approach for cloud computing environments

Abstract

Cloud computing is a convenient and cost efficient way that refers to the running of software over a network, as on a local computer. But, what is cheap and easy, isn't always safe. Stor-ing important data on cloud means that you give up a certain control of privacy. Privacy pro-tection is a very important issue in cloud computing. In this paper,we focus on the need of cloud users managed services and propose an approach for data protection based trust mech-anism, which using adaptive mapping resources based on trust to ensure the user data protec-tion initiative, and data security. The analysis shows that the cloud user can independently con-trols the content and manner of services by using the approach, which can achieve the free de-ployment of resources and the balance of user data protection and service provided.
