Abstract

A method for authenticating a document (D) is disclosed, the document comprising a plurality of text fields, an authentic document comprising, among the plurality of text fields, a plurality of characters printed in a reference font, and at least one character, whose position is determined, being printed in a font that is modified relative to the reference font. The method comprises: receiving an image of the document to be authenticated, extracting, from the image, a region of interest containing the character having the determined position, evaluating discrepancies between the character contained in the extracted region of interest and a character model, and determining the authenticity of the document based on the evaluated discrepancies.
