Device Comfort for mobile health information accessibility

The Device Comfort methodology uses an enhanced notion of trust to enable a personal device to better reason about the state of interactions and actions between it, its owner, and the environment. This includes allowing a better understanding of how to manage information in fine-grained context as well as addressing the personal security of the user. As an information security methodology based on trust and thus context, it perfectly matches the growing security need for protecting users´ medical data, stored as Electronic Health Records and/or partial medical data online or on device. In this paper, we present a threelevel information architecture for managing information access in healthcare that uses Device Comfort as an enabling methodology. We further discuss the interesting potentials for storage of information and how the Device Comfort model can assist in making trust-based sharing decisions regardless of the availability (or capacity) of its owner.
