  • Publication number: 20070290124
    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.

  • Publication number: 20060093191
    Abstract: A finger sensing device may include a finger sensing area to receive a user's finger moved in a sliding motion, a sensor controller cooperating with the finger sensing area for collecting image data therefrom, an image processor, and a communications path for sending image data from the sensor controller to the image processor. The sensing device may use at least one of the sensor controller and the image processor for (i) selecting a reference image data subset based upon reference image data, (ii) selecting a new image data subset, and (iii) comparing the new image data subset to the reference image data subset to develop a matching score, and, if the matching score is above a matching threshold, then not having new image data corresponding to the new image data subset sent over the data communications path, and, if the matching score is below the matching threshold, then having the new image data corresponding to the new image data subset sent over the data communications path.

  • Publication number: 20060088195
    Abstract: A finger sensing device may include a finger sensing area to receive a user's finger moved in a sliding motion, and a controller cooperating with the finger sensing area for generating successive image samples at least some of which are separated by different time intervals. The controller may generate finger movement signals based upon the successive image samples and the different time intervals. The controller may generate a plurality of repeating groups of ratio-metrically related image samples based upon the different time intervals. The reduced number of image samples may provide greater processing efficiency and reduced power consumption.
