Systems and methods for fingerprint scanning with smudge detection and correction

A computer-implemented method, comprising:

• detecting, by a display component and during a fingerprint authentication phase, a motion of a finger;
• 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, wherein the fingerprint sensor is configured to scan a fingerprint of the finger;
• reconstructing, based on the motion of the finger and an estimated fingerprint distortion, an unsmudged fingerprint from the fingerprint data, wherein the reconstructing reduces the smudging of the fingerprint to make it detectable by a fingerprint matching component;
• and detecting the fingerprint by the fingerprint matching component, wherein the detecting of the fingerprint comprises matching the reconstructed fingerprint with a stored fingerprint template.

A non-transitory computer-readable medium, having stored thereon program instructions that, when executed by one or more processors of a computing device, cause the computing device to:

• detect, via a display component and during a fingerprint authentication phase, a motion of a finger;
• capture, via 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, wherein the fingerprint sensor is configured to scan a fingerprint of the finger;
• reconstruct, based on the motion of the finger and an estimated fingerprint distortion, an unsmudged fingerprint from the fingerprint data, wherein the reconstructing reduces the smudging of the fingerprint to make it detectable by a fingerprint matching component;
• and
• detect the fingerprint by the fingerprint matching component, wherein the detecting of the fingerprint comprises matching the reconstructed fingerprint with a stored fingerprint template.
