Systems and methods for assessing the authenticity of dynamic handwritten signature

Abstract

A system includes an electronic pen, functionally integrated with a personal computer for the acquisition and processing of signals associated with signatures, which can be network connected together with other personal computers. Each personal computer has connected as peripherals an electronic pen that includes two groups of inertial accelerometers that capture kinetic data and data about contact microvibrations with the writing support. The electronic pen also includes one self-referential optical navigation sensor that captures a series of data pairs, as momentary movements necessary in the reconstruction of the trajectory of the electronic pen and which, together with the kinetic data captured by the set of inertial accelerometers, represents personal computer input data for sensorial fusion processing and for creating the conditions to extract the information from the sensorial and psychomotric representation of a user's perspective.
