Enabling location privacy and medical data encryption in patient telemonitoring systems.
IEEE Trans Inf Technol Biomed
November 2009
Patient telemonitoring systems (PTS) deal with the acquisition, processing, and secure transmission of a patient's physiological and physical parameters to a remote location, where expert medical knowledge is available. In emergency situations, when the patient's life is threatened, the trend in modern PTS is to transmit the current location of the patient. Although research in communications security has led to mechanisms that sufficiently protect medical data, research related to location privacy area is still in its early stages.

- Recent advancements in positioning systems and telecommunications enabled the creation of EmerLoc, a location-aware medical application utilizing body sensors, a processing unit, and a central monitoring unit.
- The system's feasibility was tested through transmission speeds of DICOM images and positioning accuracy using both outdoor GPS and indoor systems, with user feedback gathered from 15 physicians in a hospital setting.
- Results indicate varying transmission speeds and acceptable positioning accuracy, with overall positive feedback from users, although some aspects of data presentation need improvement.
