It seemed like the well of information extracted from the HomePod firmware had dried up, but that couldn't be further from the truth.

Thanks to more sleuthing from developer Guilherme Rambo, details about Apple's facial recognition technology have been revealed, and the feature sounds like something out of a science fiction movie.

String found in the HomePod firmware suggest the iPhone 8 will indeed utilize facial recognition to authenticate payments and even sign into third-party apps. What's more, the feature will be capable of supporting multiple faces.

The most tantalizing bit is that Apple's facial recognition technology, which is expected to replace Touch ID, is said to be faster and more secure than a fingerprint sensor. There's even talk of facial recognition being able to mute notifications when it recognizes someone is looking at the device.

Since the HomePod firmware leaked, numerous features potentially headed to the iPhone 8 have been discovered, including improvements to the camera software.

All this talk about facial recognition still doesn't tell us whether or not Touch ID will be included in the iPhone 8, whether on the back or under the display.

Apple is expected to announce the iPhone 8 at an event in September, so we'll know more very soon. Until then, expect yet more information to be extracted from the firmware.
