Enforcing Data Privacy in Outsourced Database Services

Abstract:

Article Preview

Advances in networking technologies and the continued growth of the internet have triggered a new trend towards outsourcing data management and information technology needs to external service providers, and privacy requirements have an increasing impact on such real-world applications. In this paper, we propose a solution to enforce data privacy over outsourced database services. The approach starts from a flexible definition of privacy constraints on a relational schema, applies encryption on information in parsimonious way and mostly relies on attribute partition to protect sensitive information. Based on the approximation algorithm for the minimal encryption of attribute partition and the decomposition of SQL queries, the approach allows storing the outsourced data on a single database server and minimizing the amount of data represented in encrypted format, and allows executing queries over encrypted outsourced database efficiently.
