Battery Sleuth bypasses both the wireless communication that key fobs depend on and the standardized onboard communication network in today’s vehicles. Instead, it authenticates drivers by measuring voltage fluctuations in a vehicle’s electrical system. Drivers interact with it through a keypad device plugged into the auxiliary power outlet.

“The idea of measuring fluctuations in a car’s electrical system seems simple, but designing one device that can do it accurately on thousands of different vehicle models in varying environmental conditions gets quite complicated,” said Liang He , assistant professor of computer science and engineering at the University of Colorado, Denver and a researcher on the project. “We’re working to design a system that’s smart enough to measure the parameters of the vehicle it’s installed on and then customize itself to work effectively on that vehicle.” more
