Abstract
A method and system of writable document forgery detection including receiving a writable document, the writable document comprising one or more fields, each field being configured to receive a handwritten segment, extracting a first handwritten segment from at least one field, wherein the first handwritten segment comprises a plurality of first pixels, extracting a second handwritten segment, the second handwritten segment comprising a plurality of second pixels, assigning to each first pixel and to each second pixel a likelihood of belonging to a handwritten segment, comparing the first handwritten segment to the second handwritten segment based on the assigned likelihood of each first pixel and each second pixel, and determining whether the first handwritten segment and the second handwritten segment are from a same writer based on the comparison.
