WSJ details 3D sensor delays for iPhone X

Posted September 28, 2017

The fine print was first discovered by the Guardian in a Face ID security document published by Apple on Wednesday.

The pair combine to make Apple's brand new Face ID feature possible, with Romeo projecting the 30,000 invisible dots that create a depth map of your face and Juliet analyzing them to unlock your phone. Cooper Levenson security expert and attorney Peter Fu worries that people will take Apple's assurances on the security of Face ID to mean there's no risk of some type of hack. As The Guardian reports, Apple has made some remarkable claims about AI systems supporting the iPhone X. The company says it has developed a distinct system based on machine learning whose sole function is to detect spoofing attempts, meaning that even if Face ID proper is fooled, the secondary security system can kick in to prevent an unauthorized user from gaining access.

Turns out Face ID is pretty hard to defeat.

Well, the tech giant finally obliged - releasing a six-page overview detailing the ins and outs of the system set to replace Touch ID on the forthcoming iPhone X. The numeric representation of users' fingerprints were stored in the secure element of the iPhone's processor, and the Face ID data is stored in the exact same place.

As Touch ID does with fingerprints, Face ID and the TrueDepth camera don't actually store an image of your face. "If you're concerned about this, we recommend using a passcode to authenticate".

Face ID, for example, secures the data collected by the facial recognition technology in a similar way to how it secures users' financial and transaction data in Apple Pay. Other apps "can't access Face ID or the data associated with the enrolled face", the company said in its security white paper. The information is only available to the Secure Enclave and never leaves the device, is not sent to Apple and is not included in device backups. So, you can rest assured that snoops won't be able to unlock your phone with a photo of you, or a mask of your face. If it's a close enough match, Face ID may still save and use this model too. Users then authenticate by using the Face ID before placing the iPhone X near a contactless payment reader. Wearing hats, scarves, glasses, contact lenses, and certain sunglasses won't affect the use of Face ID. the technology works indoors, outdoors and in environments that are completely dark.

Face ID can recognize the user's face even the person changes their facial hair style.

As for what's going right with Face ID, beyond the massive demand it seems to be helping to fuel, there are a few items of note. The 10th anniversary device will be offered in 64GB and 256GB starting at $999.
