Patent

CA 2537220

According to the invention, a method for authenticating download of a number of digital content files ordered from a web site is disclosed. In one step, a selection of the digital content files is received with the web site. Download manager software, media information, the digital content files, and first codes for each of the digital content files are sent to the client computer. The media information indicates a location of each of the number of digital content files. A first code is calculated for each of the digital content files. If the client computer determines that the first code doesn't match a second code for a particular digital content file, it is resent.

L'invention concerne un procédé d'authentification de téléchargement de plusieurs fichiers de contenu numérique commandés à un site Web. Selon une étape, on reçoit une série de ces fichiers depuis le site Web. L'ordinateur client reçoit en conséquence un logiciel de gestion de téléchargement, une information multimédia, les fichiers proprement dits et des premiers codes pour chacun des fichiers. L'information multimédia indique une emplacement correspondant à chaque fichier considéré, et un premier code est calculé pour chaque fichier. Si l'ordinateur client détermine que le premier code ne coïncide par avec un second code pour un fichier particulier, une retransmission intervient.
