Peter Christen, Dinusha Vatsalan, Vassilios S. Verykios · Journal of Data and Information Quality · 2014
Techniques for integrating data from diverse sources have attracted significant interest in recent years. Much of today’s data collected by businesses and governments are about people, and integrating such data across organizations can raise privacy concerns. Various techniques that preserve privacy during data integration have been developed, but several challenges persist that need to be solved before such techniques become useful in practical applications. We elaborate on these challenges and discuss research directions.
