Face-Scanning Phones Will Also Check Live Skin Soon

Do you think fooling the face-scanning technology would be easy in the near future with all the tricks that bad actors invent with time? Then it’s time to stop worrying about it as deceiving the face-scanning phone camera would become more challenging in the coming years.

Yes, we are talking about live-skin-sensing technology that is expected to become a part of smartphones while promising a 3D scan of your face and even the assurance that the face is made up of actual flesh.

This has been made possible by Trinamix, a subsidiary of German chemical company BASF SE which has already partnered up with Qualcomm to develop algorithms for the efficient operating of 3D face scanning phones. The company has also claimed to introduce the technology in many of the budget smartphones as well.

Although detecting the living skin might sound like a creepy idea but it can benefit as a much needed extra form of verification in the facial ID scan. Previously the Face ID scan sensors found in the latest flagship smartphones like Google 4 or iPhone 11 have been based on a 3D map of infrared dots for security and 2D photo as well. But Trinamix aims to go one step further by checking backscatter on the reflected infrared and identifying whether the face is made up of living skin.

A demo of the tech also showed how Trinamix’s camera can also differentiate between materials with ease. In the sample test, two green blocks; one made up of plastic and other wood were placed right in front of the laptop. On the screen was the pixilated result of camera's IR dot backscatter which presented the blocks in different colors to show the varying materials.



Trinamix makes the recognition of materials possible by identifying the backscatter of infrared or lasers which bounce off a 3D scan. Furthermore, the machine measures every laser dot’s distance individually which serves as an incremental update to the current infrared dot-array facial scanning that finds a distortion in the pattern of dots throughout. Hence, this makes the tech to be compatible with phone, laptop or other 3D face-scanning camera system, with cameras from any suppliers.

Although Trinamix's camera prototypes are using a small Raspberry Pi computer that is being operated with an LG phone’s USB-C port but the actual array would have phone’s internal processor and would depend on same infrared dot projectors and camera sensors like the previous phones with face-scanning technology.

All being said, this level of face-scanning security can also help in identifying whether a living driver is sitting in the car or whether he has fastened the seat belt. It’s potential is also far stretched to factories or warehouses where robots are used to pick up particular objects.

However, the only question left for now is how well will this technology work in times to come.
