Latest Patents

One of his latest patents is a signature verification algorithm that utilizes dynamic signature characteristics in the frequency domain. This improved method addresses the limitations of time domain analysis, which may not effectively differentiate between genuine signatures and forgeries. The algorithm measures two acceleration components of the pen and the rate of change of axial pressure during signature creation. By employing correlation functions on both sample and reference signatures, a correlation score is generated. If this score falls within a predetermined interval, the characteristics are further analyzed in the frequency domain using the magnitude squared coherence function.

Another significant patent is a measure of distinguishability for signature verification. This method enhances the signature verification process by mapping input measures from a sample signature against a reference signature to a universal scale. The combined results yield a measure of similarity, improving the overall effectiveness of signature verification.
