Abstract
A biometric security method and apparatus for a capacitive sensor system is provided herein, where the method may include capturing a set of raw capacitive frames for a body part via the capacitive sensor system, wherein each raw capacitive frame includes a distribution of a plurality of capacitance levels measured from the body part; creating a capacitive profile based on the set of raw capacitive frames; comparing a first value in the capacitive profile to a second value in a biometric template generated from an enrolled body part, wherein the first value and the second value are located at a similar location with respect to the capacitive profile; and, generating an authentication signal based on a difference between the first value and the second value.
