Face ID could map veins to avoid confusion between twins

Face ID

This looks like something out of the James Bond gadget lab, but no, it’s real. It is a new patent that Apple has just won. His obsession with making devices more and more secure has no limits. We all know that unlocking by Face ID is one of the facial detectors safest in the world, even more than many airports.

But it turns out that such facial recognition can be circumvented with a very realistic 3D mask of a user, or simply if he has a very similar twin brother to the. To avoid this mistake, Apple intends to add the venous mapping of your face to Face ID. Thus, neither masks nor evil twins. What a cloth.

Apple’s facial recognition is one of the safest in the world. It only has one fault in a million. You can only trick Face ID with a super realistic 3d mask from the iPhone user to unlock, or with a very similar twin brother.

To avoid this, Apple has just obtained the patent entitled «Vein matching for difficult biometric authentication cases«. In this patent, Apple proposes that the answer be more than deep on the skin. Specifically, a few millimeters below the skin, as it suggests that veins could be used as a unique and unrepeatable identifier.

While facial features can be easily copied, vein patterns they differ greatly between people, even if they are twins. Since they are also under the skin and occupy 3D space, it is also extremely difficult to create a counterfeit face that takes into account the structure of the vein without the extreme cooperation of the subject, or medically invasive maneuvers.

The idea is to capture and add the map of the veins of the face to Face ID


Diagram with vein mapping included in the patent.

The system is to create a 3D map of the veins of a user using subepidermal imaging techniques, such as an infrared sensor in a camera that captures flood patterns and specks of infrared illuminators that illuminate the user’s face.

This is somewhat similar to how Face ID currently works, in that infrared light is emitted in patterns on a user’s face and read by an imaging device, but Apple’s patent is specific to the vein detection instead of the outside of the skin.

We will see if in the future this technique will be applied in Face ID of future Apple devices. Many are granted patents that never come true.
