Anomalies in network traffic can be detected aurally. The amount of electronics in cars, however, is making them more and more exposed to hacking or theft.
But, thanks to a US research team, there could soon be an easy solution. Drivers would simply plug the team’s device into the car’s auxiliary power outlet, which is directly connected to the battery.
The device is coded once like a safe with a series of voltage changes. Achieved manually by, say, turning the indicators on or off – followed by a numerical code set by the driver.
Only when, after unlocking the car, this code has been re-entered does the battery supply the engine with enough juice to start.
Self-locking bikes are also available…
