professor LSU ECE develops a mobile contact tracing application | Your money


BATON ROUGE, Louisiana, September 28, 2021 (GLOBE NEWSWIRE) – LSU electrical and computer engineering professor Lu Peng and a team of undergraduate and graduate students from ECE have developed a mobile contact tracing app COVID-19 which notifies the user if he or she has been in contact with someone recently tested positive for the virus.

The GeauxTrace app, part of a $ 888,642 grant from the National Institutes of Health that also encompasses four other virus-related projects, uses the strength of a smartphone’s Bluetooth signal to estimate distance from other smartphones. using the app, creating a contact card. If a user on the map reports positive for the virus, other users who were in the vicinity of the affected person will be notified. However, no identity is shared.

To use the app, individuals do not submit any personal information, which means that no personal phone number or email address is required to register and report. Instead, the app generates a random number from the smartphone as an identifier and broadcasts it in the background. This decentralized technique protects an individual’s privacy and the system against hacking.

“My group has been working on blockchain related projects for a few years,” Peng said. Last year, [during the COVID-19 pandemic], I was thinking of using Blockchain, which can strongly encrypt user data and protect it from hacking to protect user privacy. [In the GeauxTrace app] we record the following: time, duration, contact distance and COVID status, positive or negative.

“My app has been successfully tested by over 100 volunteers. Basically our research work has been done. The principal objective [in releasing] the application is to mitigate the spread of the virus and to help the community.

Peng is joined on the project by students Abbas Al-Hassani, Ross Browning, Tianqing Feng, William Frischhertz, Guan Lian, Tao Lu, John Ner, Fang Qi and Christopher Vasquez. Al-Hassani, Browning, Frischhertz and Lian graduated in the spring of 2021.

The GeauxTrace app is available for Android users in the Google Play Store and will soon be available for Apple devices. You can also visit for more information and to download the app.
