Patent number: 10936866Abstract: A method for detecting a document fraud is disclosed. A first image of a first document and a second image of a second document are obtained. A procedure of detection of zones sensitive to document frauds are applied in the regions of the first image and of the second image registered on the first image. Each sensitive zone detected is then divided into a plurality of subparts. A measurement of dissimilarity is calculated between corresponding subparts from the first image and the registered second image. It is then determined whether the first document is identical to the second document from measurements of dissimilarity. If the first document is different from the second document, a level of difference is determined between the first and second documents according to a value representing a proportion of different subparts; and a fraud is detected when the level of difference is below a third predetermined threshold.Type: GrantFiled: September 27, 2019Date of Patent: March 2, 2021Assignee: IDEMIA IDENTITY & SECURITY FRANCEInventors: Thibault Berger, Laurent Rostaing, Alain Rouh
