Abstract
A method for authenticating a security document by means of at least one device includes: a) providing the security document having at least one first security element and at least one second security element; b) providing the at least one device, wherein the at least one device includes at least one sensor; c) capturing first items of optical information of the at least one first security element by means of the at least one sensor of the at least one device during a first illumination, wherein at least one first dataset specifying these items of information is generated therefrom; d) capturing second items of optical information of the at least one second security element by means of the at least one sensor of the at least one device during a second illumination, wherein at least one second dataset specifying these items of information is generated therefrom; e) capturing third items of optical information of the at least one second security element by means of the at least one sensor of the at least one device during a third illumination, wherein at least one third dataset specifying these items of information is generated therefrom, wherein the second illumination differs from the third illumination; f) checking the genuineness of the security document and/or the second security element at least on the basis of the at least one second dataset and the at least one third dataset.
