Title
(EN) DIGITAL WATERMARKING AND DATA HIDING WITH NARROW-BAND ABSORPTION MATERIALS
(FR) FILIGRANAGE NUMÉRIQUE ET MASQUAGE DE DONNÉES À L'AIDE D'ÉLÉMENTS ABSORBANT DANS UNE BANDE ÉTROITE
Abstract
(EN)
The present disclosure relates to signal processing such as digital watermarking and data hiding. A sparse or dense digital watermark signal can be conveyed with a narrow-band absorption material corresponding to a center wavelength of a Point of Sale (POS) barcode scanner. The POS barcode scanner typically captures 2D imagery. Since the narrow-band absorption material absorbs over a narrow-band it is relatively imperceptible to the Human Visual System (HVS) but can be seen by the POS scanner.
(FR)
La présente invention concerne un traitement de signal tel qu'un filigranage numérique et un masquage de données. Un signal de filigrane numérique faible ou intense peut être transporté par un élément absorbant dans une bande étroite correspondant à une longueur d'onde centrale d'un lecteur de codes à barres de point de vente (POS). Ce lecteur de code à barres de POS capture généralement des images 2D. Puisque ledit élément absorbe dans une bande étroite, il est relativement imperceptible pour le système visuel humain (HVS), mais il peut être vu par le lecteur de POS.
