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.

Abstract: A person making a handwritten signature performs a series of three-dimensional movements with a plane graphical finality. The movements generate kinetic information perceived by a 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 included MEMS type acceleration sensors in the pen. The system analyzes the generated information (the signals) and determines the dynamic-biometrical characteristics based upon the biometrical dimension of the information. The characteristics are transformed into data vectors and invariants that are stored in a database. Based on algorithms, 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.

Abstract: 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.
