Glucoweb: a case study of secure, remote biomonitoring and communication.

As the Internet begins to play a greater role in many healthcare processes, it is inevitable that remote monitoring of patients' physiological parameters over the Internet will become increasingly commonplace. Internet-based communication between patients and their healthcare providers has already become prevalent, and has gained significant attention in terms of confidentiality issues. However, transmission of data directly from patients' physiological biomonitoring devices over the Web has garnered significantly less focus, especially in the area of authentication and security. In this paper, we describe a prototype system called Glucoweb, which allows patients with diabetes mellitus to transmit their self-monitored blood glucose data directly from their personal glucometer device to their diabetes care provider over the Internet. No customized software is necessary on the patient's computer, only a Web browser and active Internet connection. We use this example to highlight key authentication and security measures that should be considered for devices that transmit healthcare data to remote locations.
