Abstract

Plusieurs articles de données sont sélectionnés en vue de leur inclusion dans un fichier de façon à décourager une émission du fichier entier par un chemin de communication à largeur de bande limitée, tel que l'Internet. Chaque partie d'un fichier est liée à la totalité du fichier de données de façon que des parties des fichiers de données qui sont distribuées indépendamment puissent être distinguées. Dans le cas d'enregistrements audio, par exemple, le fichier de données inclut un album entier, chacune des chansons de l'album constituant les parties de ce fichier de données. En reliant chaque chanson de l'album, un reproducteur compliant peut être configuré de façon à refuser de restituer des articles en l'absence du fichier de données entier. De cette façon, le vol d'une chanson nécessite le vol de l'album entier. Un enregistrement numérique non comprimé d'un album entier consomme des centaines de méga-octets de données et l'infaisabilité ou l'impraticabilité du téléchargement de centaines de méga-octets de données est supposé susciter un découragement suffisant pour le vol du matériau de contenu non comprimé. Selon un mode de réalisation préféré, un filigrane est créé pour chaque section des données envoyée qui contient un "paramètre d'intégralité" associé au fichier de données. Ce paramètre d'intégralité est une valeur hâchée qui se base sur un nombre aléatoire stocké dans les filigranes de chaque section. Lorsqu'il est présenté pour restitution, le paramètre d'intégralité est lu, et les filigranes d'une sélection aléatoire de sections, dans les limites du fichier de données, sont comparés à ce paramètre d'intégralité pour s'assurer, avec une certitude statistique, que la totalité du fichier de données est présent.
