Abstract
More and more, devices around us are being connected to each other in the realm of Internet of
Things (IoT). Their communication and especially
collaboration promises useful services to be provided to end users. However, the same communication channels pose important privacy concerns
to be raised. It is not clear which information
will be shared with whom, for which intents, under
which conditions. Existing approaches to privacy
advocate policies to be in place to regulate privacy.
However, the scale and heterogeneity of the IoT entities make it infeasible to maintain policies among
each and every entity in the system. Conversely,
it is best if each entity can reason on the privacy
using norms and context autonomously. Accordingly, this paper proposes an approach where each
entity finds out which contexts it is in based on information it gathers from other entities in the system. The proposed approach uses argumentation
to enable IoT entities to reason about their context
and decide to reveal information based on it. We
demonstrate the applicability of the approach over
an IoT scenario
