Abstract
Some disclosed methods may involve receiving an indication of a digit touching a surface of an apparatus in an active fingerprint sensor area, obtaining current fingerprint image data from the digit and performing a first authentication process based, at least in part, on the current fingerprint image data. Responsive to determining that the first authentication process is an unsuccessful authentication process, some methods may involve obtaining non-digit image data after the digit has been removed from the surface, performing a second authentication process based, at least in part, on the non-digit image data and providing a notification regarding the outcome of the second authentication process. In some examples, the non-digit image data may be obtained and the second authentication process may be performed without providing a notification regarding the unsuccessful outcome of the first authentication process.
