Abstract
Example methods, systems, computer-readable media, and apparatuses for on-screen optical fingerprint capture for user authentication are presented. These allow for the authentication of a fingerprint where the fingerprint image is propagated in a glass layer before being captured by a camera. In some examples, such propagation can result in multiple fingerprint images resulting from total internal reflection within the glass layer. Feature information can then be determined from the captured image of the fingerprint, which can include multiple fingerprint images. The amount of feature information can then be reduced. A histogram associated with the captured image based on the reduced number of features can be generated, and a user can be authenticated based on the histogram.
