Report: iCloud+ Private Relay could spell the end of iOS ad fingerprinting
What you need to know
- Apple will ship iCloud+ Private Relay alongside iOS 15 this fall.
- A new report considers the privacy feature to be the "beginning of the end" for iOS device fingerprinting.
Apple's iOS 15 release, due to arrive this fall, will see the arrival of iCloud+ and its new Private Relay feature. It'll obfuscate a user's IP address to help prevent them from being tracked across the internet and, according to one report, it could spell the end for iOS device fingerprinting.
According to DigiDay, some ad execs believe that Apple isn't enforcing its App Tracking Transparency (ATT) rules as harshly as it could — but that Private Relay could be the ace in the hole.
Private Relay will re-route an iPhone, iPad, and Mac's data through an Apple server and then out via another one that's owned by a trusted third party. Nobody knows who that third party is, and it's the use of separate ingress and egress servers that ensures a user's privacy — web services will have no idea what their actual IP address is. And neither will the trusted third party, either. It's here where it's thought Apple's anti-fingerprinting goal will really kick in.
What's more, DigiDay believes that Private Relay is just the start, with more Apple-led privacy moves to come that could yet further hinder device — and user — identification across the internet. But it isn't perfect.
It's that cat and mouse game that Apple has signed itself up for and, so far at least, it seems to be up for the fight. Who will win, nobody knows — but I know where my money's going. Privacy is one of the best iPhone features around and that's why Apple promotes it so heavily. It has the bit between its teeth and won't be letting go of it any time soon.
