Abstract
(EN)
An information burying device is provided to prevent stopping of reproduction of contents photographed without bad intention. The information burying device for burying a plurality of watermark information data on a reproducing time axis of contents is comprised of an acquiring means for acquiring contents reproduced on the time axis, a watermark information generating means for generating the watermark information in a manner for a value of the watermark information to change on a regular basis in accordance with a disposed order of the reproducing time axis and a burying means for burying each of not less than two watermark information data from the plurality of the watermark information data into the contents with the maintenance of the disposed order on the reproducing time axis.

L'invention concerne un dispositif d'enfouissement d'information pour empêcher l'interruption de la reproduction de contenus photographiés sans mauvaise intention. Le dispositif d'enfouissement d'information pour enfouir une pluralité de données d'information de filigrane sur un axe de temps de reproduction de contenus est composé d'un moyen d'acquisition pour acquérir des contenus reproduits sur cet axe, un moyen de production d'informations de filigrane pour créer ces informations d'une manière telle qu'une valeur des informations de filigrane change régulièrement en accord avec un ordre disposé de l'axe de temps de reproduction et un moyen d'enfouissement pour enfouir au moins deux informations de filigrane à partir de la pluralité de données d'information de filigrane dans les contenus avec la maintenance de l'ordre disposé sur l'axe de temps de reproduction.
