Hackers are frequently intruding into car cameras. How to protect your privacy in the car?

As cars become more and more intelligent, in order to realize functions such as driver face recognition and driver fatigue driving reminder, a relatively common thing must be installed in the car, which is an in-car camera. Therefore, the use of in-car cameras has become more and more common in recent years, and has even become standard equipment on some brand models. So, are in-car cameras safe? How should smart cars support information security protection?

In 2021, a well-known foreign new energy vehicle caused a stir on the Internet due to the leakage of high-definition footage captured by the camera in the car, triggering heated public discussions. Judging from the leaked high-definition video, the actions of the driver and passengers in the car , facial expressions were all captured clearly, and there was no privacy at all. So, why does the camera in the car automatically record and upload the video? How to prevent in-car cameras from hackers? Is there any way for car owners to choose to turn on and off the camera?

Recently, according to our actual investigation, for car owners and drivers, most in-car cameras are still a passive control item, which means that car owners or drivers have no way to actively turn them off, which undoubtedly leaves hackers with a problem. A big hole was made.

However, we found that there are still a few brands that have done a lot of work in this area, such as BYD Auto. Our investigation found that BYD has installed an information security defense with double-layer security redundancy of software and hardware for the in-car camera. Some models have the camera cover physically closed, and some have electronic control. system.

It is obvious that whether it is physical shielding or electronic switching, the cost of these two solutions is minimal, but the effect is immediate, and it is worth learning from domestic and foreign automobile brands.

If you think this is all BYD’s information security defense system, you are totally wrong. After learning more about it, we found that BYD's information security defense system covers multiple dimensions from the car to the cloud. Whether it is vehicle information security or driving safety, it can make users knowable, perceptible, and controllable. This is undoubtedly Give users a great sense of security.

In addition to some of the physical methods we mentioned above, BYD will provide users with permission management solutions on mobile APPs and large-screen vehicles, and users can actively choose. In terms of dealing with network attacks and hacker intrusions, BYD has won many national competition awards. For example, BYD won the gold medal in the 2nd China Intelligent Connected Vehicle Information Security Challenge.

With the advent of the information age, it has gradually become everyone's consensus that information security is no small matter. The competition of intelligent cars will eventually be the competition of vehicle informatization. For smart cars, vehicle machine information security and autonomous driving safety are important issues related to the safety of users’ personal and property safety and cannot be ignored. At the same time, we hope that various car brands can unite to jointly maintain vehicle information security issues.
