Abstract

Dans un système de distribution électronique, une partie de l'information électronique W, stockée dans une machine serveur (1) d'un émetteur, est prélevée pour constituer un échantillon A qui est envoyé à une machine utilisateur (2) d'un récepteur. La machine serveur (1) comprend un moyen (10) de production d'éléments électroniques qui divise les parties restantes X de l'information électronique en une pluralité d'informations d'éléments Yi. Elles sont envoyées à la machine utilisateur (2) via différents chemins de communication et sont intégrées pour restaurer la partie restante X par un moyen (20) de restauration d'éléments électroniques de la machine utilisateur (2). La partie restante X est intégrée avec la partie d'échantillon A pour restaurer l'information électronique W devant être utilisée. De cette manière, lorsqu'il s'agit d'échanger de l'information électronique, un acheteur peut passer commande après avoir confirmé le contenu et il est possible d'envoyer, en toute sécurité, l'information électronique.
