Claim One:
1. An apparatus for determining a presence of a patterned biometric object, the apparatus comprising: a biometric sensor system configured to detect a presence of the patterned biometric object, to sense an image corresponding to the patterned biometric object and to translate the image into image data; logic configured to be enabled based upon detecting the presence of the patterned biometric object, and to determine multiple values corresponding to multiple different statistical properties of the image data the logic comprising a plurality of statistical engines for the corresponding multiple values, and a plurality of comparators coupled to said plurality of statistical engines for generating output signals, the output signals indicating when the multiple values exceed a corresponding number of threshold levels; and a signal generator configured to receive the output signals generate a wake up signal in the event a predetermined combination of the multiple values exceed a corresponding number of threshold levels.
