    摘要： A method and a security element with a front side and a rear side lying opposite the front side, wherein the security element has two or more security features, wherein a first security feature of the two or more security features has one or more first layers and a second security feature of the two or more security features has one or more second layers, wherein the first security feature and the second security feature are in particular arranged in register with each other, wherein the first security feature generates at least one first optically variable effect and the second security feature generates at least one second optically variable effect, wherein the at least one first optically variable effect has a first color and the at least one second optically variable effect has a second color, wherein the first color and the second color differ from each other, as well as a method for producing a security element.

    摘要： A see-through security element (2), a security document (1) and a method for producing a see-through security element (2). The see-through security element has a first element with one or more transparent first partial areas and at least one reflective second partial area. The see-through security element has a second element with one or more first partial areas, which in each case in transmission form a color filter matched to a respectively assigned color, and has at least one second partial area, which is formed colorless, in particular colorless transparent, or in transmission and/or reflection forms a color filter which is matched to a color which is not assigned to any of the one or more first partial area of the second element. The first partial areas of the first element and the first partial areas of the second element at least partially overlap.

    摘要： A method for verifying a security document by means of a reading device wherein first transmission and/or reflection properties of a first region of the security document are detected in a first spectral range by the reading device and a first data set specifying these properties is generated therefrom, wherein the first region at least in some regions overlaps an optical security element arranged on the security document or embedded in the security document and wherein second transmission and/or reflection properties of the first region of the security document are detected in a second spectral range by the reading device and a second data set specifying these properties is generated therefrom, wherein the first spectral range differs from the second spectral range, and wherein, the authenticity of the security document and/or of the security element is checked on the basis of at least the first data set and the second data set.
