1. A method for authorizing an electronic device having a capacitive touch sensor to perform an action, the method comprising: detecting, with the capacitive touch sensor, a first set of interaction data from an interaction between the capacitive touch sensor and a capacitively interactive hardware tool, the capacitively interactive hardware tool comprising: a substrate, a set of capacitive contact areas arranged in a spatial pattern on the substrate, and a current coupler comprising an electrically conductive material and electrically coupled to the set of capacitive contact areas; wherein proximity of the set of capacitive contact areas of the capacitively interactive hardware tool to the capacitive touch sensors results in a detected change of capacitance at the capacitive touch sensor when the current coupler is electrically coupled to a current sink or current source; computing, on the electronic device, a first set of parametric descriptors from the first set of interaction data; transmitting the first set of parametric descriptors to a remote database system; generating, on the remote database system, a first set of identity data from a comparison of the first set of parametric descriptors with a known set of parametric descriptors, the known set of parametric descriptors contained in the remote database system; and authorizing, in response to the first set of identity data, the electronic device to perform an action.
