A method for the verification of handwritten signatures based on the three-dimensional correlation is proposed. The input images to the algorithms of 3D correlation are those range images obtained from the 3D information formed by the signature path. An optic system based on the laser triangulation method, allows the extracting of 3D information. The method takes into account local characteristics that set shape and pressure of signatures together, discrimining characteristics for verification that have been traditionally used separately.
