Abstract
Disclosed is a method for determining a relational imprint between two images including the following steps: —the implementation of a first image and of a second image, —a phase of calculating vectors of similarity between tiles belonging respectively to the first and second images, the similarity vectors forming a field of imprint vectors, the field of imprint vectors including at least one haphazard region disordered in the sense of an entropy criterion, —a phase of recording in the guise of relational imprint of a representation of the calculated field of imprint vectors. Also disclosed is a method for authenticating a candidate image with respect to an authentic image implementing the method for determining a relational imprint.
