data management services mandates assurances to detect

and deter malicious or faulty behavior. This is particularly

relevant for outsourced data fr a meworks in which clients

place data management with specialized service providers.

Clients are reluctant to place sensitive data under the con-

trol of a foreign party without assurances of confidential-

ity. 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 han-

dle these dimensions.
