Automatic method for detecting digital forgery

Abstract

The invention relates to a method (100) for the automatic detection of digital forgery in order to verify the conformity of a digital copy (DD) of an official document (OD). Such a method (100) mainly comprises a processing step (130) of one or more images (DF1, …, DFj, …DFm) taken from said digital copy (DD) to produce one or more images (DF1', …, DFj', …DFm') expressing residual noise, and a step (140) of analyzing this residual noise to produce a conformity result (SCj, ASC) of the digital copy (DD). Such a method (100) is arranged to be implemented by the processing unit of an electronic entity (20) for verifying such conformity, possibly in response to a request from a third-party electronic entity (40) operated by a state or a service provider.
