Patent
CA 2318445
The present invnetion relates to electronic books that are accessed over a computer network, such as the Internet. As seen in the figure, one embodiment of the invention relates to a shared electronic book (12), i.e. a book in which multiple users (14) each have the right to access the book but only one of the users is allowed to actually access the book at a given point in time. Another embodiment of the invention relates to the detection of potentially fraudulent access of an electronic book. Yet a further embodiment of the invention is concerned with preventing electronic copying of an electronic book (34) when the book is provided to users over an intranet (16) that is not under the direct control of the provider of the electronic book.
L'invention porte sur des livres électroniques auxquels on peut accéder par l'intermédiaire d'un réseau informatisé tel qu'Internet. Comme le montre la figure, l'une des réalisations de l'invention porte sur un livre électronique partagé (12) c.-à-d. auquel plusieurs utilisateurs (14) peuvent accéder, mais auquel un seul peut accéder à la fois. Une première variante de l'invention traite de la détection des tentatives frauduleuses d'accès à un livre électronique. Une autre variante traite des moyens d'empêcher la copie d'un livre électronique (34) lorsque le livre est présenté à des utilisateurs via un intranet (16) n'étant pas sous le contrôle direct du pourvoyeur du livre électronique.
