Software Keeps Sensitive Data Confined in Physical Space

In a breakthrough that could aid labs doing sensitive research, keepers of medical records, and parents who want to prevent their kids from sexting, a team of Virginia Tech researchers has created software to remotely put smart phones under lockdown. The phones are given permission to access sensitive data while in a particular room, but when the devices leave the room, the data is completely wiped.

“This level of complexity and security, nobody else has,” said Jules White, assistant professor of electrical and computer engineering at Virginia Tech. “There are commercial products that do limited versions of these things, but nothing that allows for automating wiping and complete control of settings and apps on smart phones and tablets.”

A general, for example, could access secret intelligence while visiting a secure government facility without fear that his or her smart phone or tablet computer might later be lost or stolen, White said. “This system provides something that has never been available before. It puts physical boundaries around information in cyberspace.”

Medical caregivers could review patient information during a doctor visit, but – safeguarding patient privacy – doctors or nurses couldn’t walk out of the examination room with the patient’s records.

The software also enables central control of phone features such as preventing a smart phone’s camera or email from working.

“For instance, you could keep certain apps from working in the operating room so surgeons wouldn’t get distracted, or you could prevent nurses from taking patient photos and putting them on the Internet,” White said. "In that same way, parents could restrict when and where children could send text messages to prevent distraction at school. Parents could also limit to whom messages with images could be sent in order to prevent sexting."

White and his team, in research underwritten by Virginia Tech Applied Research Corporation, modified Google’s Android operating system to create the security features. The team demonstrated the software for an inside-the-beltway group, Virginia Tech Intelligence and Defense Executive Alumni, or VT IDEA (, composed of Virginia Tech alums who are interested in research that may benefit intelligence and military agencies.

“It was exciting to connect the VT IDEA group with Jules White and his team,” said John Provo, director of the Virginia Tech Office of Economic Development. “Technology like this may be ripe not only for commercialization, but it could also improve our nation’s defense and security.”

Graduate students working on the project are Paul N. Miranda of Columbia, S.C., and Danny Guymon of Fredericksburg, Va., both working on master’s degrees in electrical and computer engineering; and Hamilton Turner of Nashville, working on a Ph.D. degree.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
