Face ID is supposed to be even more accurate. Even twins can no longer unlock each other's iPhones

Face ID has been with us for some Friday and many different tests of reliability and functionality have been carried out. Most of the conclusions say that Face ID is a reliable and almost flawless system, but it suffers from minor ailments in rare cases. These cases include, for example, situations where the iPhone is able to unlock the owner's biological twin. However, that should change.

When Apple introduced Face ID to the world, one of the main assets should have been the security of the entire system, which theoretically exceeds the original solution in the form of Touch ID several times. Even then, however, Apple warned that in the case of identical or extremely similar twins/siblings, a problem can sometimes arise. This was also confirmed by tests that specifically focused on this issue.

It has been proven several times that a locked iPhone can unlock a twin or a very similar relative. In one case, the iPhone was even unlocked by a child who the iPhone identified as his mother. However, these inaccuracies should disappear, as Apple is developing a solution that will make facial reading even more accurate.

The information comes from a recently published patent that describes the operation of an additional facial mapping layer that focuses on the position, size and shape of the user's facial veins (vessels). The new system would have a function for detailed skin measurements, thanks to which it would be possible to map this hitherto hidden system of identification markers in detail. Siblings can be very similar in appearance (in many cases even unrecognizable), but the physical distribution and layering of blood vessels in the face is another unique element that makes up the overall mosaic of the human face.

This new system would use the same tools as regular Face ID - that is, an infrared sensor with a 3D projector that would be set up to capture additional information. Facial vessel mapping would also eliminate the risk of unlocking the device using detailed (and very expensive) 3D masks, which have been able to bypass the security system in some tests.

The so-called "vein matching” is currently an actively developed identification method used by, for example, the FBI. However, the system is definitely not finished and it cannot be expected that this functionality would appear, for example, in this year's iPhones. It is rather a promise for the future. Face ID will be here some Friday and Apple will try to make the whole system as perfect as possible. This can be just one of the steps forward.
