With the rapid development of cloud computing, more cloud services are into the people daily life, and thus security protection of cloud services, especially data privacy protection, becomes more important. However to perform privacy protection causes huge overhead. Thus it is a critical issue to perform the most suitable protection to decline performance consumption while provide privacy protection. In this paper, the Effective Privacy Protection Scheme (EPPS) is proposed to provide the appropriate privacy protection which is satisfying the user demand privacy requirement and maintaining system performance simultaneously.
