An SQL-like query tool for data anonymization and outsourcing

Abstract

Data anonymization is an important preprocessing step for data sharing and the delegation of data storage to the cloud. In this paper, we propose an SQL-like query language and a tool to help the data provider ensuring the quality and the privacy of the data being outsourced. The tool supports a set of recent and well-known anonymization techniques in an SQL query style. We present our framework and the language capabilities. We report on experimental evaluation and results.
