Abstract
A device for producing a document carrying the identification of a person/animal. A first detector to determine the printing conditions of the document. A sensor to obtain the biometric data of the person/animal. A first encoder encodes the biometric data to form a digital identification image including redundancies. A second detector to determine physical characteristics of cells of at least one shape, such that the proportion of cells printed with a print error results from unanticipated unknowns in printing. A second encoder to form, within the shape, an authentication image for authenticating the document and includes elementary cells representing the encoded authentication image. A printer to print the authentication and identification images on the document, and to generate random errors in the printed elementary cells of the authentication image to detect modification to the appearance of the elementary cells.
