This is particularly relevant for outsourced data frameworks in which clients place data management with specialized service providers. Clients are reluctant to place sensitive data under the control of a foreign party without assurances of confidentiality. Additionally, once outsourced, privacy and data access correctness (data integrity and query completeness) become paramount. Today's solutions are fundamentally insecure and vulnerable to illicit behavior, because they do not handle these dimensions. In this chapter we will explore the state of the art in data outsourcing mechanisms providing strong security assurances of (1) correctness, (2) confidentiality, and (3) data access privacy.
