The goal of this chapter is to describe the main solutions being devised for protecting data confidentiality and integrity in outsourcing scenarios. In particular, we illustrate approaches that guarantee data confidentiality by applying encryption or a combination of encryption and fragmentation. We then focus on approaches that aim at guaranteeing data integrity in storage and in query computation. Finally, we present some issues that still need to be investigated for ensuring privacy and security of data outsourced to external servers.

Abstract
The goal of this chapter is to describe the main solutions being devised for protecting data confidentiality and integrity in outsourcing scenarios. In particular, we illustrate approaches that guarantee data confidentiality by applying encryption or a combination of encryption and fragmentation. We then focus on approaches that aim at guaranteeing data integrity in storage and in query computation. Finally, we present some issues that still need to be investigated for ensuring privacy and security of data outsourced to external servers.
