About David Kotz

David Kotz is the Champion International Professor in the Department of Computer Science at Dartmouth College. He served as Associate Dean of the Faculty for the Sciences for six years and as the Executive Director of the Institute for Security Technology Studies for four years. In 2013 he was appointed to the US Healthcare IT Policy Committee. His research interests include security and privacy, pervasive computing for healthcare, and wireless networks. He has published over 100 refereed journal and conference papers and obtained over $65m in grant funding. He is PI of a $10m grant from the NSF Secure and Trustworthy Cyberspace program and leads a five-university team investigating Trustworthy Health & Wellness technology (see thaw.org). He is an IEEE Fellow, a Senior Member of the ACM, a 2008 Fulbright Fellow to India, and an elected member of Phi Beta Kappa. After receiving his A.B. in Computer Science and Physics from Dartmouth in 1986, he completed his Ph.D in Computer Science from Duke University in 1991 and returned to Dartmouth to join the faculty.

Amulet released at SenSys’16

Today at the ACM Conference on Embedded Networked Sensor Systems (SenSys 2016) the Amulet team presented a paper about the design and evaluation of the Amulet platform – and unveiled a video overview of the platform and its capabilities. Check out the specs below the photo.

Indeed, we are pleased to share the Amulet hardware and software, open-source on GitHub, under a generous license that allows free use by the research community. We encourage you to download the details, fabricate your own Amulet wearable, and let us know what you think!

New grant to apply Amulet to study obesity in elderly people

Dr. John Batsis, DHMCThe Amulet team is collaborating with geriatrician Dr. John Batsis of Dartmouth-Hitchcock Medical Center to explore the use of the Amulet in developing intervension methods to help obese elderly people maintain function while they remain living at home.  This “grant … from the National Institute on Aging will allow Dr. John A. Batsis to focus on strategies for improving health care delivery and wellness in older adults with obesity by using video conferencing, personal monitoring devices and frequent coaching by healthcare providers.” [press release]

Check out the video interview with Dr. Batsis on WCAX television.

This research is supported by the National Institute On Aging of the National Institutes of Health under Award Number K23AG051681.

Wearable Amulet design

A few weeks ago we assembled our first complete Amulet, ready for wearing!   Here are a few shots so you can get a look at the case – which is mounted on a off-the-shelf wristband we hacked to encase the battery.





On one side, a button and a scrollwheel.



On the other side, two buttons.

On top, a low-energy display (like e-ink).

Amulet presented at mHealth Summit

logo for the mHealth SummitPerhaps the largest annual event related to mHealth is the mHealth Summit, held near Washington DC.  Today, the summit kicked off with a Privacy & Security Symposium, including a presentation by David Kotz on Developing a Secure mHealth Platform for Wearables, in which he described the Amulet project.  The talk presented the Amulet approach to providing a wearable hub for body-area mHealth applications, and our latest hardware and software prototypes.  The talk generated a lot of interesting questions from the audience of about 60-70 people.

More news once we publish our new paper describing Amulet – hopefully within the next six months.

Amulet paper to appear at WMMADD

I’m pleased to share a new paper that we’ll be presenting next month at the Workshop on Mobile Medical Applications – Design and Development (WMMADD)  at SenSys in Memphis.

Abstract: Interest in using mobile technologies for health-related applications (mHealth) has increased. However, none of the available mobile platforms provide the essential properties that are needed by these applications. An mHealth platform must be (i) secure; (ii) provide high availability; and (iii) allow for the deployment of multiple third-party mHealth applications that share access to an individual’s devices and data. Smartphones may not be able to provide property (ii) because there are activities and situations in which an individual may not be able to carry them (e.g., while in a contact sport). A low-power wearable device can provide higher availability, remaining attached to the user during most activities. Furthermore, some mHealth applications require integrating multiple on-body or near-body devices, some owned by a single individual, but others shared with multiple individuals. In this paper, we propose a secure system architecture for a low-power bracelet that can run multiple applications and manage access to shared resources in a body-area mHealth network. The wearer can install a personalized mix of third-party applications to support the monitoring of multiple medical conditions or wellness goals, with strong security safeguards. Our preliminary implementation and evaluation supports the hypothesis that our approach allows for the implementation of a resource monitor on far less power than would be consumed by a mobile device running Linux or Android. Our preliminary experiments demonstrate that our secure architecture would enable applications to run for several weeks on a small wearable device without recharging.
