What can GPS do?

GPS is no stranger to us. Obviously, many people now prefer to use GPS to do something else.

See who comes first

This is a survey report from the British ICM Research Research Company. In the past year, after surveying 7.2 million British drivers, they found that half of them would be connected to the GPS satellite navigation device in the car. "More than time."

When we get into the car and set a good destination and route on the GPS, the system will provide an “estimated arrival time,” and many drivers see this as a “clocking pass” in the video game. A sense of challenge has been inspired. Half of them have experienced speeding behavior. Of the 7.2 million people surveyed in total, 144,000 had traffic accidents smashed with other vehicles and 200,000. As a result, people crashed into roadblocks, 16.1 million people had aggressive driving behavior similar to horns and headlights against other vehicles or pedestrians, 1.2 million people seized yellow lights, and 570,000 people did not pass through the intersection. Reduce the speed.

The GPS used in the car was originally designed to provide the driver with convenient driving, but also reduced the risk of driving while watching the map. However, scientists who have developed GPS navigation systems did not think that the drivers found Another pleasure in using GPS, but this brings unsafe side effects to new technologies.

Send a message to the car

I believe many people have this experience: hurry to get on the train, fasten the seat belt, start the car, set the GPS, and start!

In fact, these five steps can be completely simplified. Recently, General Motors added new features to its exclusive OnStar system. This function is to transfer the driver's GPS setting in the car to the mobile phone. Users only need to download an App program to their mobile phone, and they can connect to the RemoteLink (Remote Link) system of the vehicle. The user only needs to find a good destination on the mobile phone, and then send it via text message or voice message. To the system terminal, the car's navigation system reacts.

This system can currently allow up to five destination commands to be stored. In this way, the navigation system in the car after the driver gets in the car is already set, and it is in a standby state. It can be used at any time according to the route plan sent by the mobile phone in advance. Conduct guidelines.

OnStar's design director Steve Schwinke stated: "RemoteLink's navigation gain program can provide drivers with a lot of convenience while driving. Whether they are in the car, in front of a computer, or in a mobile phone in their hands, they can plan ahead in time. route."

Perhaps the future of this system can be combined with the driverless system, we only need to send a short message to the car or make a phone call, the car will automatically open to the scheduled location to pull goods.

Stealing a car with a mobile phone

The link between the mobile phone and the car is more than that. Not long ago, the US iSec Partners security consultant warned: “The thief can use the smart phone's App application to remotely open the door and start the vehicle.” Two researchers Don Bailey, Mathew Solnik also demonstrated this process, they only need a laptop and mobile app program to complete this task.

According to Don Bailey, using a computer to crack the signal sent by a mobile app to a vehicle can take only about an hour or two.

He also discussed this issue in the "Black Hat Technical Security Conference" in Las Vegas, but refused to reveal how he broke the specific details of the car by breaking the communication protocol between the vehicle and the mobile phone. This will not be disclosed until the application vendor fixes it.

iSecPartners security consultants believe that this issue reflects a bigger problem, that is, the design of the communication protocol between the mobile phone and the vehicle is too hasty, so it will be so easy for researchers to crack and directly enter the core system of the vehicle.
