  • Finger sensing device with spoof reduction features and associated methods
    Patent number: 8180118
    Abstract: A finger sensing device may include a finger sensing area, at least one processing stage coupled to the finger sensing area and having at least one adaptively determined processing parameter, and a controller for spoof reduction. More particularly, the controller may determine a spoof attempt based upon a change in the at least one adaptively determined processing parameter. For example, the at least one adaptively determined processing parameter may include a feedback determined processing parameter. Accordingly, the finger sensing device has enhanced spoof reduction, since different materials, for example, will cause a change in an adaptive processing parameter and thereby indicate the attempted spoof.
