Thus, MAC addresses are a bit of a battleground for personal data privacy.įor several years now, iOS and Android have supported MAC randomization, which is a way to dynamically change the MAC address used for over-the-air communications. Because of that uniqueness, the MAC address historically represented the chip itself, the device with the installed chip, and the user that carries it around.
The chip uses the MAC address for network communications, which, in wireless, are sent over the air for all to see. Mac RandomizationĪs many of you know, MAC addresses are “burned in” identifiers of radio chips that give them what is supposed to be a unique worldwide address. As we know, Apple has been a strong privacy advocate all along (their marketing teams will tell you again and again), but in iOS 14, they almost took it to a whole new level.
As data analytics have evolved from snowball to avalanche, data privacy initiatives have been standing in the gap between individuals and the companies that wish to harness their data.
