摘要

"METHOD AND APPARATUS FOR AUTHENTICATING SIGNATURES AND METHODS OF ELECTRONIC LEARNING AND COMPARISON OF THE SAME WITH PREVIOUSLY STORED REPRESENTATIONS". Signature authentication method including the steps of supplying the signature sample and storing the representative signature data, converting the data into high-dimensional vectors, feeding the high-dimensional vectors to an unsupervised neural network, carrying out an extraction process of main components of high order on the vectors of high dimensions, in order to, thus, identify the groupings of high dimension points, and analysis of the groupings of high dimension points, to determine, based on previously stored information, the authenticity of the signature . Also a device for this authentication, including a signature sample collection device and storage of the representative signature data, a conversion device connected downstream to the sample collection device for converting the data into large dimension vectors, a neural network unsupervised to receive the high dimensions and carry out a process of extraction of main components of high order on the vectors of high dimensions, in order to, thus, identify the clusters of high dimension points, and an analysis device connected to the unsupervised neural network, to analyze the groupings of large points in order to determine the authenticity of the signature.
