Query: Privacy, Trust and Identity in Pervasive Computing: A Review of
  Technical Challenges and Future Research Directions   Developments in pervasive computing introduced a new world of computing where
networked processors embedded and distributed in everyday objects communicating
with each other over wireless links. Computers in such environments work in the
background while establishing connections among them dynamically and hence will
be less visible and intrusive. Such a vision raises questions about how to
manage issues like privacy, trust and identity in those environments. In this
paper, we review the technical challenges that face pervasive computing
environments in relation to each of these issues. We then present a number of
security related considerations and use them as a basis for comparison between
pervasive and traditional computing. We will argue that these considerations
pose particular concerns and challenges to the design and implementation of
pervasive environments which are different to those usually found in
traditional computing environments. To address these concerns and challenges,
further research is needed. We will present a number of directions and topics
for possible future research with respect to each of the three issues.
