New technology protects your smartphone from unwanted personal data collection
Right now, your phone is probably transmitting data about your location, even with GPS turned off. This is because when you register your SIM cards, phones provide cell towers with personal identifiers, which are then stored by the operators. This has led to the fact that almost every person on the planet can be tracked in real time and sell this data to third parties without permission. In this regard, U.S. scientists have developed technology that maintains user privacy while ensuring normal mobile communications.
New technology will protect your smartphone from unwanted collection of personal data
Technology anonymizes smartphone personal identifiers and prevents “leaks” of location and identity data
Now, for communication to work, the network must know your location and identify you as a paying customer. Thus, the device constantly tracks both your identity and your location data. In doing so, unscrupulous operators can collect this data and sell it.
Experts from the University of Southern California and Princeton University presented their technology called Pretty Good Phone Privacy at the USENIX Security conference. It allows mobile communications, but it anonymizes personal identifiers that go to cell towers.
Their development cuts the connection between the user’s cell phone and the cell tower and sends an anonymous token instead of a personal identifier. And the protocol created by the American specialists allows to confirm the solvency of the client – also anonymously.
The new technology does not overload the channel, works without delays and can handle tens of millions of users on one server. It is important to note that the system does not allow to track the identity and location of the user, but it does not interfere with navigation applications.
