MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517049848 A) filed by Google Llc, Mountain View, U.S.A., on May 23, for 'systems and methods for fingerprint scanning with smudge detection and correction.'
Inventor(s) include Sammoura, Firas; and Miller, James, Brooks.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "An example device includes a display component comprising a fingerprint sensor configured to scan a fingerprint of a finger. The device includes one or more processors operable to perform operations, including detecting, during a fingerprint authentication phase, a motion of the finger. The operations include capturing, by a fingerprint sensor of the display component, fingerprint data associated with the fingerprint, the motion of the finger having caused a smudging of the fingerprint. The operations include reconstructing, based on the motion of the finger and an estimated fingerprint distortion, an unsmudged fingerprint from the fingerprint data. The reconstructing reduces the smudging of the fingerprint to make it detectable by a fingerprint matching component. The operations include detecting the fingerprint by the fingerprint matching component. The detection of the fingerprint comprises matching the reconstructed fingerprint with a stored fingerprint template."
The patent application was internationally filed on Dec. 12, 2023, under International application No.PCT/US2023/083533.
