Samsung files patent application for contactless fingerprint reader technology


Samsung has filed a U.S. patent application for a new non-touch method for fingerprint recognition on mobile devices, according to a report by Venture Beat.

According to the patent application, users position their fingertip in front of a mobile device’s camera. The device then takes an image of the fingertip and searches for a positive match with a valid fingerprint image that is stored on the phone’s memory.

The technology is able to automatically alter the camera’s focus until it secures a high quality capture of the fingerprint image.

The system also features an on-screen guide that helps users accurately line up the fingertip with the camera.

This contactless method is more accurate and potentially faster than full-contact fingerprint readers, as well as accounts for external factors that can affect accuracy, such as the dryness of a user’s hand or motion distortions in fingerprint pattern.

Although the patent was filed in the Korean Intellectual Property Office on November 22, 2013, it is also recognized by the U.S. Patent Office.

Previously reported, Encap Security recently released Smarter Authentication 3.0 platform, which includes added support for Samsung’s fingerprint scanner.
