Zusammenfassung:	A method for verifying a hologram (3), comprising the steps of reading at least two images of the hologram (3), the images being representative of images derived at respective different viewing angles, comparing a characteristic derived from the respective images with a reference characteristic to establish if the hologram is authentic, and outputting a signal indicative of the authenticity of otherwise of the hologram (3). Procédé de vérification d'un hologramme (3), qui comporte la lecture d'au moins deux images de l'hologramme (3), les images étant représentatives d'images produites à des angles de vision différents respectifs, la comparaison d'une caractéristique tirée des images respectives à une caractéristique de référence pour établir si l'hologramme est authentique, et la production d'un signal indicateur de l'authenticité ou non de l'hologramme (3).
