Description

  ABSTRACT

          Cloud computing provides massive computation power and storage capacity which enable users to deploy computation and data-intensive applications over the internet as well as without infrastructure investment. Along the processing of such applications and data, a large volume of intermediate data sets will be generated, and it might be stored to save the cost of re-computing the application or data. However, preserving the privacy of  inter-mediate data sets becomes a challenging problem because  ,the adversaries may recover privacy sensitive information  from the cloud  by analyzing the multiple intermediate data sets.
