Samsung's Future Galaxy Phones Could Add Palm Reading To Display Password Hints
A patent filed [PDF] by Samsung, however, looks to take the uncertainty regarding password hints out of the equation with what is effectively a palm reading. Samsung’s smartphone-based system will scan the unique lines that are spread across the palm of your hand. Once your palm is scanned, and you are authenticated as the rightful owner of the device, the phone will display incomplete characters from your password hint. The full password hint won't be given, but it should be enough to trigger your memory to input the correct answer.
We don't think that we'll see such technology taking the place of first-tier authentication systems like fingerprint scanning (seen on just about every modern smartphone these days) or facial scanning (as seen with Face ID on the iPhone X). But as a solution for a second line of defense like a password hint, it seems like a usable method.
Samsung's Galaxy S9 flagship is reportedly set to launch early next year, but it's unknown if that flagship device will feature a palm reader. We do know, however, that the smartphone will feature a Samsung Exynos 9810 or a Qualcomm Snapdragon 845 processor along with dual cameras on its backside.
