Researchers identify autoroute without gps




Scientists at Rutgers University have developed a method just by measuring the speed of a car to determine which route someone has taken. They want to demonstrate that the privacy issue can be. Using only these data

The method, which the researchers call elastic pathing, can reproduce an exact route of a motorist without requiring GPS or similar techniques. This is just a starting position and an OBD connector for car needed, which speed can be read and can be redirected to a smartphone. Via bluetooth via the vehicle management system

The software can be determined where a motorist bus service. On the basis of the speed The algorithm looks at how fast someone drives and compares that with the roads on a map from the starting position. Once the speed changes and no longer matches the assumed path, the image, the software searches for roads near where that is the case.

The scientists carried out with six directors from 240 rides in New Jersey with 46 final destinations. They also held a similar test with 21 directors, 691 rides 240 final destinations reason in Seattle. From these experiments proved the method used to determine 26 percent, with a margin of error of almost half a kilometer. Destination correctly

Just perfect, the method does not emphasize the scientists. Motorists appear identical to each other in terms of driving styles and in addition, account should be taken of the situation on the road at that time. Nevertheless, they think they can show that the location of a driver may be outdated, while no gps is used. Example of this

With that determination, the computer scientists point to American insurance companies, the speed of cars often request in order to bring. Driving behavior of their customers to map “The data goes, once collected, not go away. Enhancements also make it possible to get more personal information”, so say they. They believe therefore that alternatives should be considered to protect privacy. Better During the International Joint Conference on Pervasive and Ubiquitous Computing next month scientists will present their final findings.
