Overview of the State of the Art
This chapter discusses the state of the art in the area of data outsourcing, which is mainly focused on efficient methods for querying encrypted data. We also present some approaches for evaluating the inference exposure due to data publication, and solutions for granting data integrity. A few research efforts have instead addressed the problem of developing access control systems for outsourced data and for securely querying distributed databases.
