Abstract
With recent advances in wearable technology and the rapid adoption of wearable devices, there are increased opportunities for setting up innovative data markets through which large amounts of user-generated physiological data can be made available to health researchers at relatively low costs. However, given the sensitive nature of such data, a major challenge associated with realizing a trusted wearable data marketplace is ensuring fine-grained access control and assuring conformance to it. In this paper, we propose a policy-based approach for facilitating the secure exchange of data between a wearable owner and a health researcher. User-defined data-sharing policies are translated into executable smart contracts that provide deterministic and transparent execution of transactions as per the terms and conditions of the data sharing agreement. To illustrate feasibility of the approach, we present a proof-of-concept implementation of the proposed policy-based access control mechanism using the open source Multichain platform.
