A modern car is increasingly perceived not just as a means of transport, but as a complex computing system that constantly interacts with external servers. The car regularly transmits diagnostic data to the manufacturer or dealer, and many sensors operate inside it: from GPS and speedometer to microphones, cameras, and tire pressure sensors.
Even if information is not sent in real-time, it is stored in the onboard computer's memory. This data can describe in detail the routes, habits, and daily activities of the owner.
Digital Evidence
Law enforcement agencies have long paid attention to this source of information. In investigations, a car can be considered not only as a physical object but also as a data repository.
Technologies of so-called “automotive intelligence” (CARINT) allow extracting from the car:
- GPS movement history
- information about calls, media player, and voice commands
- lists of connected devices and contacts
- data on mileage, engine operating modes, and other parameters
Such information is often used as evidence. There are known cases where car recordings disproved an alibi. In one US case, a voice command confirming the suspect's presence behind the wheel became key evidence.
With the spread of connected cars, access to such data has become simpler. Movement history and other information can be obtained directly from manufacturer servers, sometimes without physical access to the car.
Combining Sources
Data obtained from a car is rarely used in isolation. For a more complete picture, it is compared with other sources:
- information from the car's SIM card
- Bluetooth connection data
- street camera recordings
- information from commercial data brokers
This comprehensive approach allows detailed tracking of a person's movements and contacts. Some publications also mentioned the possibility of remotely activating microphones and cameras, although experts emphasize that due to the variety of technologies, this is not always feasible.
"Factory" Capabilities and Limitations
Theoretically, remote access functions to sensors can be part of the car's standard capabilities, not the result of hacking. There is little public confirmation of this, but attention to such risks is growing.
Some countries have already introduced restrictions: for example, certain car models are not allowed on military facilities, or additional security requirements are established for them. This highlights concerns about potential data access.
Cheap Surveillance Methods
However, surveillance does not always require complex technologies. Studies show that even simple tire pressure sensors (TPMS) can be used for tracking.
Their features:
- wireless data transmission without encryption
- unique identifier
- ability to record car movements
Additionally, such data can indirectly indicate the car's load – for example, whether the driver is alone. This method is less technological but accessible and works even on cars without internet connection.
How to Reduce Risks
Completely eliminating data collection is difficult, but the amount of available information can be reduced. Basic measures include:
- refusing to synchronize your smartphone with the car
- regularly clearing data in the multimedia system
- limiting data transmission through proprietary applications
- refusing to use voice control
There are also more radical approaches:
- using cars without modern telematics systems
- disconnecting communication modules.
However, such measures can reduce convenience, safety, and even affect warranty or legal compliance.
The modern car is indeed becoming a source of large amounts of data that can be used not only by manufacturers but also by law enforcement agencies.
On the one hand, this increases the effectiveness of investigations. On the other hand, it creates new risks for privacy. Therefore, the choice of protection level is always a compromise between convenience, security, and privacy.
