Privacy Protection through Query Rewriting in Smart Environments
Hannes Grunert, Andreas Heuer · Movebank · 2016
By the events in the past years, the integration of data protection mechanisms into information systems becomes a central research problem again. In this technical report for our poster, we show how query rewriting can be used to maintain privacy of users in smart (or assistive) environments. We developed a privacy respecting query processing and a vertical fragmentation of queries, processing maximal parts of the query as close to the sources of the data (e.g. sensors) as possible.
