Methods, apparatus, and computer program products for controlling access to an electronic device based on biometric input are described. An example of such a method includes receiving a current biometric input, determining template similarity scores for the current biometric input, if at least one template similarity score satisfies a template similarity score criterion, then updating a false user counter value in a first numerical direction and performing an authentication process on the current biometric input, else, determining stored biometric input similarity scores for the current biometric input, if at least one stored biometric input similarity score satisfies a stored biometric input similarity score criterion, then maintaining the false user counter value, else, replacing a previously stored biometric input with the current biometric input, and updating the false user counter value in a second numerical direction opposite to the first numerical direction. |

1. A method of controlling access to an electronic device based on biometric input, comprising:
receiving a current biometric input; determining one or more template similarity scores for the current biometric input; if at least one template similarity score of the one or more template similarity scores satisfies a template similarity score criterion, then updating a false user counter value in a first numerical direction and performing an authentication process on the current biometric input, else:
determining one or more stored biometric input similarity scores for the current biometric input;if at least one stored biometric input similarity score of the one or more stored biometric input similarity scores satisfies a stored biometric input similarity score criterion, then maintaining the false user counter value, else:
replacing a previously stored biometric input with the current biometric input; andupdating the false user counter value in a second numerical direction opposite to the first numerical direction. |
