Dartmouth College researchers have developed a digital “magic wand” to improve house healthcare and to forestall hackers from stealing your private knowledge.

The system1, referred to as “Wanda,” might be introduced on the IEEE International Conference on Computer Communications in April.2


“Wanda” is a part of a National Science Foundation-funded venture led by Dartmouth referred to as “Trustworthy Health and Wellness” three. THaW goals to shield sufferers and their confidentiality as medical data transfer from paper to digital type and as health care more and more strikes out of docs’ workplaces and hospitals and into the house.


David Kotz, a professor of pc science at Dartmouth, says wi-fi and cellular health applied sciences have nice potential to improve high quality and entry to care, scale back prices and improve health. “But these new technologies, whether in the form of software for smartphones or specialized devices to be worn, carried or applied as needed, also pose risks if they’re not designed or configured with security and privacy in mind.”


One of the primary challenges is that most individuals do not understand how to arrange and keep a safe community of their house, which may lead to compromised or stolen knowledge or probably permit hackers entry to essential units reminiscent of coronary heart fee screens or dialysis machines. There are three elementary operations when bringing a brand new cellular gadget into the house, office or clinic: to configure the system to be a part of the wi-fi local-area community; to companion the system with different close by units to allow them to work collectively; and to configure the system so it connects to the related particular person or organizational account within the cloud.


In the brand new Dartmouth-based undertaking, doctoral scholar Tim Pierson developed “Wanda,” a small hardware system that has two antennas separated by one-half wavelength and makes use of radio power as a communication channel. The intelligent answer makes it straightforward for individuals to add a brand new system to their residence (or clinic) Wi-Fi community: they merely pull the wand from a USB port on the Wi-Fi entry level, carry it shut to the brand new system and level it on the system. Within a number of seconds, the wand securely beams the key Wi-Fi community info to the system. The similar technique can be utilized to switch any info from the wand to the brand new gadget with out anybody close by capturing the secrets and techniques or tampering with the knowledge.


“People love this new approach to connecting devices to Wi-Fi,” says Pierson. “Many of our volunteer testers remarked on the frustration they’ve encountered when configuring wireless devices at home and ask when they can take our wand home.”


Kotz provides: “We anticipate our `Wanda’ technology being useful in a wide variety of applications, not just healthcare, and for a wide range of device management tasks, not just Wi-Fi network configuration.”


The THaW group conducts analysis associated to cellular and cloud know-how for health and wellness purposesfour, together with authentication and privateness instruments to shield health data, strategies to safe small-scale medical networks and efforts to scale back malicious exercise in hospitals. Supported by a $10-million, five-year grant from the NSF’s Secure and Trustworthy Cyberspace program, the Frontier-scale venture consists of specialists in pc science, enterprise, behavioral health, health coverage and healthcare info know-how at Dartmouth College, Johns Hopkins University, the University of Illinois Urbana-Champaign (UIUC), the University of Michigan and Vanderbilt University.
