Current technologies make it easy to track people's locations using a smartphone. When they connect to base stations, the information is registered with the mobile operator. In 2011, at the request of German politician Malte Spitz, a mobile provider sent him encrypted data on his movements. When decrypted, it showed that the provider was storing the smallest details of his routes for a six-month period. It is important to know that among the many millions of mobile applications, there are those that collect information on movements, even if the developers do not need it.

, such as automated license plate readers (ALPRs). They are nepal whatsapp data by law enforcement and insurance companies to track stolen or pawned vehicles. The Electronic Frontier Foundation believes that ALPRs are illegal because they track not only the movements of violators, but also the movements of millions of law-abiding citizens.

Owners of E-ZPass radio transponders (used in the US to pay for toll roads remotely) and other automated devices are another risk group. For example, E-ZPass stores detailed information about the tolls paid by drivers in order to send them a detailed monthly payment report. But, as it turns out, this data can be used for more than just reporting. Last October, the New York City Department of Transportation used E-ZPass to track the movements of drivers.

One of the volunteers of the Union for the Defense of Civil Liberties managed to detect the surveillance. He noticed that the E-ZPass, attached to the windshield, was emitting some incomprehensible signals. Being a radio amateur, he created a receiver tuned to the E-ZPass wave. It was possible to discover that the device began to communicate in places where road tolls are not provided. The antennas that transmitted the E-ZPass signal about its location turned out to be disguised as road signs.
