Samsung has filed patent for a new technology that will make it easier to access its devices even if you’ve forgotten the password. A new patent application from the South Korean smartphone maker hints at use of palm recognition to hide the password hint.

A person’s palm consists of a plethora of lines that differ for every individual and Samsung believes it can hide the hint to a user’s password in those scattered lines. In a 42-page patent application, Samsung seems to be planning to use the rear camera to capture the image of a user’s palm and then convert the same into biometric information stored within the device. The patent application also shows that the password hint won’t be displayed directly and Samsung will scatter it across the lines whenever a user tries to retrieve the password hint.

Since the underlying tech relies on use of a camera and not a dedicated sensor, security is not likely to be a major emphasis here. However, the idea of scattering the password hint and not directly displaying it will make it a bit more secure than conventional methods. It is also less likely that someone will hold a user’s hand and click pictures of the palm to retrieve the password hint.

It is not immediately clear whether Samsung wants to bring this technology to market immediately but it could debut with company’s future Galaxy lineup. Samsung already offers iris scanning, fingerprint and face recognition apart from PIN and pattern for unlocking its smartphones. With the new palm recognition technology, it will only make it easier in case someone forgets the password to access their device.

Samsung is reportedly planning to showcase the Galaxy S9 with similar design to its predecessor and improved specifications at CES next month. The smartphone is likely to miss out on the under display fingerprint scanning technology, which is expected to debut with Galaxy Note 9 instead. Sammobile reports that Samsung is also working on Face ID rival combining iris scanning and new 3D face scanning technology.

Looking at the patent application, it seems straightforward and easier to implement compared to a complex feature like 3D face scanning. The feature might end up on Samsung’s upcoming smartphones and could also make its way down to older Galaxy devices through software updates.
