Assignee: THE BANK OF NEW YORK MELLON
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A system for real-time electronic signature verification in a data-sparse computer environment, the system comprising:
cloud-based storage circuitry configured to store a first image, wherein the first image comprises a first signature, wherein the first signature is an authenticated signature;
control circuitry configured to:
determine a first sequence, wherein the first sequence comprises a sequence of intensity for both vertical and horizontal concatenations of pixels composing the first image;
extract a first dynamic behavior of the first sequence, wherein extracting the first dynamic behavior of the first sequence comprises determining a first optimal stochastic transition matrix (OSTM) that represents the first dynamic behavior;
receive a second image, wherein the second image comprises a second signature, wherein the second signature requires electronic verification;
determine a second sequence, wherein the second sequence comprises a sequence of intensity for both vertical and horizontal concatenations of pixels composing the second image;
extract a second dynamic behavior of the second sequence, wherein extracting the second dynamic behavior of the second sequence comprises determining a second optimal stochastic transition matrix (OSTM) that represents the second dynamic behavior;

determine an authenticity of the second signature based on comparing the first dynamic behavior to the second dynamic behavior;
select a recommendation from a plurality of recommendations based on the authenticity; and

input/output circuitry configured to generate for display, on a user interface, the recommendation.
