Abstract :
Summary form only given. Cloud computing promises an open environment where customers can deploy IT services in pay-asyou-go fashion while saving huge capital investment in their own IT infrastructure. While cloud provides a promising infrastructure for big data applications such as medical data analysis, privacy preservation becomes critical because user privacy is a serious concern in practice. In this talk, we will discuss privacy preservation in general and then propose our solutions for scalable privacy preservation of big data applications on cloud.
