摘要
A finger sensor may include a finger sensing area and a controller cooperating with the finger sensing area for storing enrollment data including finger feature locations. The controller may be for generating authentication data including finger feature locations based upon positioning of an object adjacent the finger sensing area. The controller may also be for performing aligning the authentication data and the enrollment data, matching between the aligned enrollment and authentication data, and spoof attempt detecting based upon corresponding pairs of finger features and their spatial locations in the aligned enrollment and authentication data. The controller may further be for performing an authentication decision based upon the matching and spoof detecting.
