Title
(EN) IMAGE DISTORTION FOR CONTENT SECURITY
(FR) DISTORSION D'IMAGE POUR SÉCURISER UN CONTENU
Abstract
(EN)
A software module is presented that enables a person to determine the relevance of an electronic document while preventing the person from making a complete copy of the document. In one embodiment, this is accomplished by displaying an image that represents a region of interest and conveys the context of the region of interest within the document while distorting other portions of the document. In one embodiment, the software module is used in conjunction with a search engine to generate an image of a search result document.
(FR)
L'invention concerne un module logiciel qui permet à une personne de déterminer l'importance d'un document électronique tout en empêchant cette personne de faire une copie complète du document. Dans un mode de réalisation, une image représentant une zone d'intérêt est affichée, cette image véhiculant le contexte de la zone d'intérêt à l'intérieur du document, d'autres parties du document faisant l'objet d'une distorsion. Dans un autre mode de réalisation, le module logiciel est utilisé en combinaison avec un moteur de recherche pour générer une image d'un document de résultats de recherche.
