Can't Hide Your Stride: Inferring Car Movement Patterns from Passive TPMS Measurements
Summary
The paper shows that passive TPMS transmissions, which are unencrypted and persistently identify vehicles, can be used to infer sensitive information about car movement and driver behavior. A low-cost setup collected data over 10 weeks from 12 cars, suggesting scalability to thousands and highlighting privacy risks; authors call for more secure, privacy-preserving TPMS designs.
