The Database group mission is to provide data management to create added value on top of autonomous data sources.

Nowadays huge amounts of data are produced by both humans and devices connected to the Internet. This has led to information overload and a decrease in trust of data, as well as an increase of privacy threats. However, applications need high data quality providing privacy. Our research extends database systems with functionality to filter and compute relevant information, to reduce the unreliability of data, and to protect privacy.

·	Search on semi-structured data Specifically, XML databases and distributed search

·	Enriching uncertain data Specifically, data integration and streaming data

·	Security and Privacy Specifically, search in encrypted data, secure handling of medical data, and progressive degradation of data

Applications: web search, sensor network, e-Health, ambient intelligence
