Samsung is developing a new biometric recognition technology. This is based on a full hand scan by the camera.
Smartphone unlocking technologies have evolved considerably. PIN codes, patterns, and passwords have given way to biometric identification, which is faster, more convenient, and more secure. On Android devices, fingerprint scanning is the preferred method (via a scanner placed under the screen or on the edge), while Apple has replaced Touch ID with Face ID facial recognition on its iPhones. What if a new method were added to this selection?
Samsung has in any case filed a patent in Europe that goes in this direction, reports Patently Apple. It describes a palmprint recognition feature. This system would scan the entire palm of the hand rather than just one finger as is currently the case, which would strengthen the security of smartphones.
Samsung is working on a palm scan
Since you can't place your entire hand on a mobile, which wouldn't be very intuitive to unlock anyway (and would require a huge fingerprint reader), the idea would be to use the rear camera. A hand would then have to be placed in the sensor's field of vision to initiate the palm recognition process.
This technique is based on obtaining at least "three characteristic coordinates from a palm image obtained via the camera module", we learn. The system will then “identify a rotation angle relative to the palm based on the at least three characteristic coordinates and adjust a palmprint recognition zone based on the rotation angle relative to the palm,” it says.
In addition to fingerprints, a palm scan can collect other biometric information, such as the shape of blood vessels, or the shape of wrinkles and fine lines on the palm. Such a function appears to be much slower than traditional fingerprint scanning. It could complement, not replace, it, to offer a more secure option for those who do not trust current technology.
