Valtteri Niemi received a PhD degree from the University of Turku, Finland, Mathematics Department, in 1989. After serving in various positions in Univ of Turku, he was an Associate Professor in the Mathematics and Statistics Department of the University of Vaasa, Finland, during 1993-97. He joined Nokia Research Center (NRC), Helsinki in 1997 and in 1999 he was nominated as a Research Fellow. During 2004-2006, he was responsible for Nokia research in wireless security area as a Senior Research Manager. During 2007-2008, Dr. Niemi lead the Trustworthy Communications and Identities team in the Internet laboratory of NRC, Helsinki. He recently moved to the new NRC laboratory in Lausanne, Switzerland, where his main focus is on privacy-enhancing technologies. He was also nominated as a Nokia Fellow in 2009.

Privacy and identity in context-aware services
Abstract:
There is a rapidly growing trend towards mobile services that utilize
context of the user. This context could be in the physical dimension (e.g.
space and time) or in social dimension (e.g. friendship or collegial
relationship). These kinds of services tend to be privacy-sensitive. New ways
of combining physical and digital worlds also call for new types of
identities. Technologies that help in managing the interplay between privacy
and identity (but also security and trust) are presented. Areas covered vary
from identification of radio devices to usage control of the
privacy-sensitive context data.
