Abstract
The invention relates to a method and system for optical product authentication, in which a product is labeled with optically active particles, a reference image is recorded in a registration step and a recognition image of the optically active particles is recorded in a recognition step. The product is then authenticated by comparing image data or a coding derived from image data in the registration step versus the recognition step.
