What is face ID?

face ID on the iPhone X

A biometric authentication. Rather than a password or a security dongle or authentication app, biometrics are something your personnel. Fingerprint recognition is also biometric.

Touch ID has one or more fingerprints; face ID relies on the unique characteristics of your face.

They design face ID for unlocking an iPhone X by identifying unique facial characteristics as it projects and analyzes over 30,000 invisible dots that precise depth map of the user’s face.

Where faced ID come from?

3D scanning from PrimeSense developed some technologies used in the face. An Israeli company Apple purchased in 2013.

Face ID also uses tech purchased when Apple gained Emotions in 2016 and Real Face in February 2017.

How do I set up a face ID?

Just like with touch ID, face ID uses an enrollment process.

For that go to settings–face ID and Passcode and tap enroll face, and then the iPhone will use the front-facing camera to display your face within a circle with green tick marks surrounding it.

Enrollment software will quasi-3D markings on the screen to show your eye line and facial center. They will prompt you to move your head in a circle, while it captures your facial characteristics.

Is face ID secure?

face ID when launched, Apple said it worked hard to ensure things, like photographs, can spoof face ID.

With professional mask-makers and make-up artists it works well. In Hollywood to train its neural networks and thus protect face ID against those sorts of bypass attempts.

Protects a secure enclave in the bionic chips. I do all the processing on the chips, whether that be the A11 or A12. So, it does not send your face data to a server.

Apple says that someone else’s fingerprint will unlock Touch ID is 1 in 50,000. For face ID apple says of another face matching is 1,000,000.

During the iPhone X introduction Apple’s senior vice president of worldwide marketing, Phil Schiller said that “The statistics are lower if the person shares a close genetic relationship with you.”

Apple clarified this in its white paper, nothing that the accuracy is different for twins and siblings. You should avoid face ID if you have an evil twin.

Children under 13 had a higher rate of false matches, though it did not provide a number. Because in children distinct facial features may not have fully developed.

Is there an emergency way for switching off face ID?

You will enter the emergency SOS screen when you press the sleep/wake button five times in rapid succession.

Tap on the cancel button so that face ID will be disabled. And you will need your Passcode to use your iPhone.

It should let you disable face ID discreetly in some situations and can be seen as face ID’s emergency brake.

When can’t I use face ID?

Most times, use a Passcode. (use these parameters with Touch ID also):

  • After restart.
  • After the 48-hour period in which you have not used face ID to unlock the phone.
  • After 6 ½ days. A four-hour timer will start, if you don’t use face ID within that period that means four-hour period then you are prompted for a Passcode when you next time unlock.
  • After five failed attempts to unlock with face ID.
  • After disabling using any technique above not already mentioned in this list.

What next for face ID?

Apple not telling us what it plans to do. But I think we will see the company introduce face ID APIs so developers can use more of the information put together by the system in their own apps.

There are other potential developments in the long-term banks in Macau are using face recognition at ATM’s, and Mexico has used a face recognition system to prevent voter fraud.

Will governments recognize face ID as an approved imaging system suitable for passports at one day?

If it happens, then you will travel across borders carrying nothing but an iPhone.
