Abstract
An electronic device may include a finger biometric sensor and a processor being switchable between a user-interface locked mode and a user-interface unlocked mode. The processor may cooperate with the finger biometric sensor to acquire spoof detection data based upon an object being placed adjacent the finger biometric sensor, and determine whether the acquired spoof detection data is representative of a live finger. The processor may also switch from the user-interface locked mode to the user-interface unlocked mode when the acquired spoof detection data is representative of a live finger, and cooperate with the finger biometric sensor to acquire biometric matching data. The processor may further perform finger matching based upon the acquired biometric matching data and stored biometric enrollment data.
