Dynamic handwriting verification, handwriting-based user authentication, handwriting data generation, and handwriting data preservation

摘要: Handwriting verification methods and related computer systems, handwriting-based user authentication systems are disclosed. A handwriting method comprises obtaining a test sample containing plurality of available parameters, extracting geometric deriving features comprising an x-position value y-position for each feature points in the sample, performing matching between reference determining result based at least part on matching, outputting result. Techniques tools generating preserving electronic data also Raw is converted to streamed format that preserves original content raw data. inserting into digital image
