Inferring Car Movement Patterns from Passive TPMS Measurements

4 hours ago

TPMS transmissions from modern cars are sent in clear text with a long-lasting unique identifier.
A study collected TPMS data over 10 weeks using low-cost spectrum receivers, tracking 12 verified cars but observing over 20k cars.
TPMS data can reveal sensitive information like presence, type, weight, or driving patterns of the driver.
The equipment needed to exploit this privacy issue is affordable, costing as low as $100 per receiver.
The findings highlight the need for policymakers and car manufacturers to develop more secure and privacy-preserving TPMS designs.
