Abstract
Système de traitement de données comportant un moyen de protection contre des programmes non autorisés. Le système se compose d'une unité de sortie 2 commandée par le processeur de données 1 qui peut émettre des documents de valeur ou une information à diffusion restreinte, et d'une mémoire de données divisée en une mémoire de sécurité 4 contenant les instructions de sortie, une mémoire libre 5 et un circuit logique de sécurité 12 pour contrôler qu'une instruction de sortie provient bien de la mémoire de sécurité et empêcher le fonctionnement d'une unité de sortie recevant des instructions de sortie de la mémoire libre. Un tel système empêche l'obtention frauduleuse de documents de valeur ou d'une information à diffusion restreinte par chargement d'un programme dans la mémoire libre.
