1. A method for authentication on an electronic device having a capacitive touch sensor comprising:

  • detecting, on the capacitive touch sensor, a first set of points of capacitively interactive contact resulting from proximity of a hardware tool to the capacitive touch sensor, wherein the hardware tool is not a human hand;

    wherein the first set of points is arranged in a spatial pattern;

    wherein detecting the first set of points comprises detecting the first set of points substantially simultaneously;

    computing, from the first set of points, a first set of parametric descriptors;

    generating a first comparison between the first set of parametric descriptors and a set of known parametric descriptors; and

    authenticating an event on the electronic device based on the first comparison.
