IPhone X Face ID spills secrets as Apple talks security

Adjust Comment Print

The new site and the white papers essentially outline Apple's commitment to privacy as it introduces more personal and potentially sensitive features and services. The paper answers a handful of the most pressing privacy and security related questions that people have had in the weeks following the iPhone X reveal.

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

Apple added that the probability of someone's face unlocking another device is unlikely. The technology uses its front-facing cameras and sensors that create a map of the face to determine if you are the phone's owner. Next, the camera captures a separate 2D infrared image with the help of something called a flood illuminator, which is what helps the phone see your face in the dark. Numbers representing all the beams, taken together, create a mathematical expression of the unique contours of the user's face. But, he said, Apple has built in security that might make the job so labor-intensive and expensive that it wouldn't be worth it. Hackers like technical challenges, but when there's real money on the line they'll tend to go for the low-hanging fruit.

While Face ID won't face an acid test with ordinary users until November, Apple says it should work just fine. 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. Apple also lays out exactly what it's storing: infrared images of your face captured when you first start Face ID, the mathematical representations of your face it calculates during that enrollment and whatever other images the phone deems necessary to account for changes to your face (a beard growing over time, for example). While the chances of someone successfully unlocking your iPhone Touch ID are one in 50,000, that number jumps to one in a million with Face ID, the company said.

"Face ID data doesn't leave your device, and is never backed up to iCloud or anywhere else". Apps don't get access to facial scans or any of the data in the Secure Enclave. Maybe you forgot to shave for a few days, or made a decision to cut off all your hair.

In Burjeel, Eman suffered from kidney dysfunction and heart disease that worsened her condition in the last few days. She also shared pictures of Eman suffering frequent seizures and tremors and crying in pain to prove her point.

Face ID will allow only five unsuccessful match attempts before a passcode is required.

"If you're concerned about this, we recommend using a passcode to authenticate", the memo reads.

Mogull said Face ID can probably be fooled if somebody tried hard enough. 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.

So how anxious should we be about Apple's Face ID? Apple says it will use the technique to understand what emoji people like, and what auto-correct suggestions are most used.
