Privacy Preserving Data Processing

A data processing functions are expected as a key-issue of knowledge-intensive service functions in the Cloud computing environment. Cloud computing is a technology that evolved from technologies of the field of virtual machine and distributed computing. However, these unique technologies brings unique privacy and security problems concerns for customers and service providers due to involvement of expertise (such as knowledge, experience, idea, etc.) in data to be processed. We propose the cryptographic protocols preserving the privacy of users and confidentiality of the problem solving servers.
