Taking on the global innovation around facial recognition technology, the Korean technology major Samsung is reported to be working on a camera system for facial recognition that involves two under-display cameras.

According to reports, the new technology is described in a patent application Samsung filed with the KIPRIS (Korea Intellectual Property Rights Information Service) back in March 2021. The document in question was made public last week and picked up by a Dutch publication.

The new technology can help get multiple images of the user from two angles to better construct a 3D model of the face and use that for authentication purposes.

Samsung has so far experimented with the technology on its Galaxy Fold line without a broader release, the report said. The patent of the new technology also does not really go into so much detail.

However, it does show a mockup of a regular “slab” style phone with two UDC cameras — one at the top and one at the bottom. Another thing mentioned in the patent is measuring pupil size.

As per the report, the idea is that a human's pupil size should vary depending on lighting conditions. This could be used as an extra security measure against using things like photos or masks to trick facial authentication.
