Authenticating Drivers Using Automotive Batteries
summary
BAuth authenticates drivers by reading a battery voltage fingerprint produced by a driver’s customized start sequence and matching that fingerprint on an add-on module between vehicle and battery that then gates engine cranking by reducing or restoring battery output power. A six-vehicle prototype authenticates with a 98.17% true positive rate and 2.84% false positive rate, tolerates aging, temperature, and state-of-charge changes, and a 174-owner user study reports practical acceptability.
