Patent

CA 2271012

A method of transmitting protected video and/or graphic data over the Internet from a Web site, by encrypting the video and/or graphic data and storing it at a Web site associated with a server, and by encrypting a video player and storing it at the Web site. Both are then downloaded (70) to a requesting computer via the Internet or Intranet. The requesting (72) computer decrypts the video and/or graphic data and video player via a previously supplied decryption key, so that the video may be played back by the decrypted player.

La présente invention concerne un procédé permettant de transmettre via l'Internet depuis un site Web des données vidéo et/ou graphiques protégées. Ce procédé consiste à crypter les données vidéo et/ou graphiques et à les stocker au niveau d'un site Web associé à un serveur, puis à crypter un module de restitution vidéo et à le stocker au niveau du site Web. On prend ensuite les données et le module et on les télécharge via l'Internet ou un Intranet vers un ordinateur demandeur. L'ordinateur demandeur décrypte les données vidéo et/ou graphiques et le module de restitution vidéo au moyen d'une clé de décryptage préalablement fournie, de façon à pouvoir utiliser le module décrypté pour restituer la vidéo.
