A method for hardware-tool-based authentication includes detecting a first set of capacitive contact points and a second set of capacitive contact points, computing, from the first set of capacitive contact points, a first set of parametric descriptors, generating a first comparison of the first set of parametric descriptors and a set of known parametric descriptors, generating a second comparison of the first set of capacitive contact points and the second set of capacitive contact points, and performing an event on the electronic device based on analysis of the first and second comparisons.
