The invention refers to a computer-based system for the acquisition, analysis, and authentication of the handwritten signature. The person that performs a handwritten signature performs a series of three-dimensional movements with a plane graphical finality. The movements generate kinetic information perceived by the special pen that the signature is performed with (the writing and digital acquisition device for the primary bio-kinetic information). The information, concordant to the afferent bio-kinetic pattern, is collected by the included MEMS type acceleration sensors in the pen. The system continues to analyze the generated information (the signals) and it determines the dynamic-biometrical characteristics, based upon the biometrical dimension of the information. The characteristics are transformed in data vectors and invariants that are stored in a database. Based on algorithm type methods, the system performs the required comparisons between the spatial kinetics of the specimens and the kinetics of the entrances and obtains distance-type answers. In statistical terms, the results are related to the entire subject database, by interpreting and sampling methods.

Système informatique pour l'acquisition, l'analyse et l'authentification de signature manuscrite, sachant que la personne qui signe effectue une série de mouvements 3D à finalité graphique plane. Les mouvements engendrent une information cinétique perçue par un stylet spécial servant à la signature (dispositif d'écriture et d'acquisition numérique pour l'information biocinétique primaire). L'information, correspondant au profil biocinétique afférent, est recueillie par les capteurs d'accélération de type MEMS incorporés au stylet. Le système continue d'analyser l'information engendrée (les signaux) et détermine les caractéristiques dynamiques-biométriques, sur la base de la dimension biométrique de l'information. Les caractéristiques sont transformées en vecteurs de données et invariants enregistrés dans une base de données. A partir de procédés liés à l'algorithme, le système fait les comparaisons requises entre la cinétique spatiale des spécimens et la cinétique des entrées et recueille alors des réponses, liées à la distance. En termes statistiques, les résultats sont mis en relation avec toute la base de données visée, par des techniques d'interprétation et d'échantillonnage.
