Patent

CA 2593952

The present invention discloses an apparatus (110) and method for defining and enforcing rules of transition between two security domains, e.g., a transport domain (120) and a persistent security domain (130). In turn, a border guard, e.g., a security device (114), is provided between these two domains that enforce rules for transition between the two security domains. This novel approach of defining a transport domain (120) and a persistent security domain (130) simplifies the classification of the digital content (106) and its movement through the system. Namely, the border guard once established between the two systems can enforce DRM rules associated with how contents (106) are moved between the two domains.

La présente invention concerne un appareil et un procédé permettant de définir et de faire valoir des règles de transition entre deux domaines de sécurité, par exemple un domaine de transport et un domaine de sécurité permanent. Une barrière frontalière, par exemple un dispositif de sécurité situé entre ces deux domaines, fait valoir des règles de transition entre les deux domaines de sécurité. Cette nouvelle approche de définition de domaine de transport et d'un domaine de sécurité permanent simplifie la classification des contenus numériques et leur déplacement à travers le système. C'est-à-dire que la barrière de frontalière une fois établie entre les deux systèmes fait valoir des règles DRM associées à la façon dont des contenus sont déplacés entre ces deux domaines.
