Abstract: Ein Berechtigungsprüfungssystem, dass eine Berechtigungsprüfungs-Prioritätsliste benutzt, die auf dynamischer und virtueller Gruppierung von Endgeräten beruht die zur Berechtigungsprüfung verwendet werden wobei das System zu einer Effizienzverbesserung der Berechtigungsprüfungs-Prioritätsabfolge bei der 1:N-Berechtigungsprüfung und bei der Hybrid-Berechtigungsprüfung führt, indem die Berechtigungsprüfungslogik zwischen 1:1- und 1:N-Berechtigungsprüfung umgeschaltet wird. Maskieren zuvor angemeldeter Benutzer für die Berechtigungsprüfungs-Prioritätsliste bei 1:N-Berechtigungsprüfung verbessert die Effizienz der Berechtigungsprüfungs-Prioritätsabfolge bei der 1:N-Berechtigungsprüfung.
