Title (EN) CONTROL AND SECRET MARKING METHOD OF A DATA CARRIER WHICH MAY BE READ BY A MACHINE
(FR) PROCEDE DE MARQUAGE SECRET ET DE CONTROLE D"UN SUPPORT DE DONNEES POUVANT ETRE LU PAR UNE MACHINE
Abstract: front page image
(EN)To prevent any falsification of a credit or identity card (60), a colour mark is applied on a selected area, defining the length or the limits of a path. The length of the path of the path is convened into digital marking data and recorded on a recording track (65). Upon checking the authenticity of the card (60), the length of the path is once again set and convened into digital marking data which must coincide or be equal with the recorded data on the recording track (65).
(FR)Afin d"empecher toute falsification d"une carte de credit ou d"identite (60), on applique, sur une zone determinee, une marque de couleur definissant la longueur d"un trajet ou delimitant un trajet. La longueur du trajet est convertie en donnees de marquage numeriques et enregistree sur une piste d"enregistrement (65). Lors de la verification de l"authenticite de la carte (60), la longueur du trajet est de nouveau etablie et convertie en donnees de marquage numeriques qui doivent coincider avec les donnees enregistrees sur la piste d"enregistrement (65).
