Apple has announced (see here) a new iCloud premium feature called iCloud Private Relay:

when browsing with Safari, Private Relay ensures all traffic leaving a user’s device is encrypted, so no one between the user and the website they are visiting can access and read it, not even Apple or the user’s network provider. All the user’s requests are then sent through two separate internet relays. The first assigns the user an anonymous IP address that maps to their region but not their actual location. The second decrypts the web address they want to visit and forwards them to their destination. This separation of information protects the user’s privacy because no single entity can identify both who a user is and which sites they visit.

More information can be found for example here and here.

This seems very much a form of Onion Routing, which is all the theory and practice of TOR (The Onion Router, indeed). It will be very interesting to see how it will work out because there is the possibility of becoming a disruptive technology to improve the privacy and security of all of us when browsing the Internet.
