摘要： In the production of a document, image information is incorporated into a plurality of layers of the document such that the pieces of image information are combined into a total image. The image information in at least two of the layers includes digital watermark information. The entirety of the digital watermark information in the at least two layers forms a security feature for an authentication of the document. The invention further relates to a respective document, a method for authentication, and a device for authentication.
