Latest Patents

One of Nelson's latest patents is a signature verification method using hidden Markov models. This method involves segmenting a smoothed and normalized signature and evaluating local features to obtain a feature-value vector. The process includes computing the likelihood that the segments with the observed sequence of feature values were generated by a specific hidden Markov model. This model comprises a sequence of states with duration probabilities and feature-value histograms. Notably, the invention incorporates explicit state-duration modeling to account for duration in the respective states underlying the unknown signature. Additionally, it computes a measure of signature complexity, adjusting the number of states of the hidden Markov model according to this complexity measure.

Another significant patent is a method and apparatus for verifying static signatures using dynamic data. In this process, an off-line test signature is compared to one or more on-line reference signatures. Dynamic data from the reference signatures can improve the thinning of the test signature and assist in segmenting and sequencing the resulting strokes. The invention also evaluates a dynamic error based on the sequencing of the test signature and produces a rendering of at least one on-line reference signature as a two-dimensional image. This rendering is then used to evaluate a static error based on shape-matching between the rendered image and the test signature.
