The invention relates to an interactive computerized system and to a method for the acquisition and processing of biokinetic information associated to a dynamic holograph signature, with a view to assessing the authenticity thereof. According to the invention, the system comprises an electronic pen (1) functionally integrated to a personal computer (2) for the acquisition and processing of signals associated to a holograph signature, which can be network connected together with other personal computers having an electronic pen (1) as a peripheral device, said pen comprising two groups of MEMS inertial acceleration sensors (A and B) for collecting kinetic information (ax, ay, bx, by) and information concerning the microvibrations at the contact with a writing carrier, an optical navigation differential sensor (ONS) for collecting a series of data pairs (dx, dy) as momentary displacements required for image-processing the trajectory of the pen (1) and which, together with the kinetic information (ax, ay, bx, by) make up the input data to the personal computer (2), an infrared LED for lighting a pattern printed on the writing carrier and a lens (L) for focusing and projecting the current image of the pattern on the area of sensitivity of the optical navigation sensor (ONS). The claimed method consists of a stage of calligraphy image processing and viewing the writing thickness and a stage of applying certain conversions and comparisons to the signs associated to the signature, with a view to assessing the authenticity thereof. |
