R2D2: Right place, right path data delivery

Data security can be enhanced by not only strong encryption techniques but also by restricting who can receive the data, as well as where and how they are received. In this paper, we focus on how to specify and verify where and how the data are received. The challenging issue here is how to utilize trustworthy 3rd party verification mechanisms to check whether a requester is in the designated area specified by the creator and whether the delivery follows a desired path. We call this new service Right Place, Right Path Data Delivery (R2D2). The current network and geolocation techniques are investigated for their capabilities in verifying and ensuring such R2D2 services. We created software tools to specify and verify such R2D2 services. We show that the verification of R2D2 services is quite challenging.
