[origin: WO2021043738A1] The invention relates to a method for checking the authenticity of a security document (3), which comprises a layer, the layer comprising a pattern (4) in the form of an image, which pattern is calculated, by means of a defined algorithm, from a number of data (6, 7) that specify the security document (3). A pattern (5) in the form of an image is calculated, by means of the defined algorithm, from the number of data (6, 7) that specify the security document, and the calculated pattern (5) is at least partially displayed on a display (2) and compared with the pattern (4) shown on the security document (3).
