Method and apparatus with fingerprint verification

A fingerprint verification apparatus comprising:

• a processor configured to:
• determine a matching region between an input fingerprint image and a registered fingerprint image;
• determine a similarity corresponding to the matching region;
• determine a matching region-based similarity based on the determined matching region and the determined similarity corresponding to the matching region;
• in response to the matching region-based similarity not satisfying a fingerprint verification condition, updating the matching region-based similarity;
• determine a result of a fingerprint verification of the input fingerprint image based on the updated matching region-based similarity;
• and
• provide a visualizing information associated with the fingerprint verification through a visual device,
• wherein the input fingerprint image is an image of a fingerprint of a user is captured by a fingerprint sensor, integrated in a display, while a finger of the user is touching on a touchscreen.

A processor implemented fingerprint verification method comprising:

• obtaining an input fingerprint image using a touchscreen;
• determining a first similarity corresponding to a first matching region between the input fingerprint image and a first registered fingerprint image;
• determining a matching region-based similarity based on the first similarity and the first matching region;
• determining a second similarity corresponding to a second matching region between the input fingerprint image and a second registered fingerprint image;
• updating the matching region-based similarity based on the second similarity and the second matching region;
• determining a result of a fingerprint verification of the input fingerprint image based on the updated matching region-based similarity;
• and
• providing a visualizing information associated with the fingerprint verification through a visual device.
