Abstract
Unease over data privacy will retard consumer acceptance of IoT
deployments. The primary source of discomfort is a lack of user
control over raw data that is streamed directly from sensors to the
cloud. This is a direct consequence of the over-centralization of
today’s cloud-based IoT hub designs. We propose a solution that
interposes a locally-controlled software component called a privacy
mediator on every raw sensor stream. Each mediator is in the same
administrative domain as the sensors whose data is being collected,
and dynamically enforces the current privacy policies of the owners
of the sensors or mobile users within the domain. This solution ne- cessitates a logical point of presence for mediators within the admin- istrative boundaries of each organization. Such points of presence
are provided by cloudlets, which are small locally-administered data
centers at the edge of the Internet that can support code mobility.
The use of cloudlet-based mediators aligns well with natural personal
and organizational boundaries of trust and responsibility.
