Latent fingerprint detection

Latent fingerprint detection

In a method for operating a fingerprint sensor, a fingerprint capture operation is performed on a fingerprint of a finger contacting the fingerprint sensor. A finger lift action is detected. It is determined whether a latent fingerprint remains on a contact surface of the fingerprint sensor subseque...

description In a method for operating a fingerprint sensor, a fingerprint capture operation is performed on a fingerprint of a finger contacting the fingerprint sensor. A finger lift action is detected. It is determined whether a latent fingerprint remains on a contact surface of the fingerprint sensor subsequent the finger lift action. If it is determined that a latent fingerprint remains on the contact surface of the fingerprint sensor subsequent the finger lift action, instruction on addressing the latent fingerprint is provided.
