Electronic authentication method of a handwritten signature, module and corresponding computer program

摘要

The method involves acquisition of data (13) representative of altitude (Z) of writing instrument with respect to a writing surface at an instant of input of signature in a proximity zone near the writing surface, where the altitude corresponds to a variable vertical distance separating a writing end of the instrument and the writing surface. The input handwritten signature is authenticated (14) by considering the altitude. Capacity is measured by using a tactile capacitive area of the surface. Independent claims are also included for the following: (1) an electronic authentication module of handwritten signature of user, comprising an acquisition unit (2) a computer program comprising instructions for executing a method for electronic authentication of handwritten signature of user.
