METHOD AND DEVICE FOR VERIFYING DIFFRACTIVE ELEMENTS |
| 摘要 |
The invention relates to a method for authenticating a diffractive element, e.g., a hologram, on an object or document (2), wherein at least two images of the diffractive element are recorded by means of a portable device (1). The recordings are taken in different spatial orientations of the portable device in relation to the diffractive element. Recording data are created from the images and the associated spatial orientations. The recording data are electronically compared with reference data. The comparison can be performed locally or in a server-based manner. |

1. A method for authenticating a diffractive element, comprising:
recording of at least two images of the diffractive element using a portable device having an image recording apparatus, wherein the images are recorded with different spatial orientations of the portable device relative to the diffractive element; determining the spatial orientations of the portable device relative to the diffractive element during the recording of the images with respect to at least two spatial directions; generating recording data from the images and the associated spatial orientations; and electronically comparing the recording data with reference data. |
