1. A fingerprint sensor device, comprising:

  • sensing circuitry to generate a sensor signal responsive to detecting a contact input associated with a fingerprint, the sensing circuitry including;

    a fingerprint sensor to detect the contact input and generate a signal indicative of an image of the fingerprint, anda live finger sensor to generate a signal indicative of an identification of the fingerprint as belonging to a live finger,wherein the generated sensor signal includes the signal indicative of the image of the fingerprint and the signal indicative of the identification of the fingerprint as belonging to a live finger; and

    processing circuitry communicatively coupled to the sensing circuitry to process the generated sensor signal to determine whether the contact input associated with the fingerprint belongs to a live finger.
