Abstract
Data outsourcing or database as a service is a new paradigm for data management.
The third party service provider hosts databases as a service. These parties
provide efficient and cheap data management by obviating the need to purchase
expensive hardware and software, deal with software upgrades and hire professionals
for administrative and maintenance tasks. However, due to recent governmental
legislations, competition among companies and database thefts, companies cannot use
database service providers directly. They need secure and privacy preserving data
management techniques to be able to use them in practice. Since data is remotely
stored in a privacy preserving manner, there are efficiency related problems such
as poor query response time. We propose a new framework that provides efficient and
scalable query response times by reducing the computation and communication costs.
Furthermore, the proposed technique uses several service providers to guarantee the
availability of the services while detecting the dishonest or faulty service
providers without introducing additional overhead on the query response time. The
evaluations demonstrate that our data outsourcing framework is scalable and
practical.
