    abstract = {We study the security challenges that arise in {\em
people-centric urban sensing}, a new sensing paradigm leveraging humans as
part of the sensing infrastructure. Most prior sensor network research has
focused on collecting and processing environmental data using a static
topology and an application-aware infrastructure, whereas people-centric
urban sensing involves collecting, storing, processing and fusing large
volumes of data related to everyday human activities. This highly dynamic and
mobile setting, where humans are the central focus, presents new challenges
for information security; not only because of the complex communication
patterns, but also because data originates from sensors carried by
people---not tiny sensors thrown in the forest or attached to animals. In
this paper we aim to instigate discussion of this critical issue, because
people-centric sensing will never succeed without adequate provisions for
security and privacy. To that end, we outline several important challenges
and suggest general solutions that hold promise in this new sensing
paradigm.}
