Seminar Monday March 5th 2018 by BigInsight and Statistics Norway: Valuable knowledge can be obtained by combining data from two or more sources, but exchanging and linking data are often unacceptable due to confidentiality and privacy concerns. Consequently, important discoveries that are important to society could be hampered. Therefore, data and results need to be processed in a way that preserves privacy. New approaches and computing methods for analyzing data distributed across multiple data sources while protecting privacy are being developed. This seminar addresses these issues with several speakers connected to Norwegian Centre for E-health Research in Tromsø. The director of the Cancer Registry of Norway is also among the speakers.
