In the US may track Putin's movement: journalist told how possible
This is stated in an excerpt from the book by American journalist Byron Tau "Means of Control: as a Secret Alliance of Technologies and Government creates a new American state of tracking" published in Wired. In his book, TAA tells of a program created in the United States, which makes it possible to track the movement of almost any person in the world according to her mobile phone. It is a mechanism by which advertisers are spreading targeted advertising.
Tau writes that every iPhone or Android phone owner Apple or Google provides an "anonymous" advertising id. This number is used to track the real displacement of a person, his or her behavior on the Internet, the applications that he sets on her phone, and much more.
"Faced with a commercially accessible data storage, so rich and detailed, the governments of the world are increasingly opening their wallets to buy this information from all, not break it or get it under the secret orders of the court," he said. According to TAU, the CIA was interested in software that could analyze and understand the geographical movement of people and things, so the CIA's venture unit invested in the relevant companies.
"Having received a set of data on Russia, the team realized that it could track phones surrounded by Russian President Vladimir Putin. The phones moved everywhere where Putin was," the author of the book says. According to TAU, the devices considered, probably belonged not to Putin himself, but to drivers, security staff, political assistants and other auxiliary personnel surrounding the Russian president.
