Abstract
A security document with a first security element, which includes a first item of visually recognizable and in particular machine-readable information, and a second security element, which includes a second item of in particular machine-readable information which can be used to verify the first item of information. A method for the authentication thereof is also described.
Claims19
A security document with a first security element, which comprises a first item of visually recognizable and machine-readable information, and a second security element, which comprises a second item of machine-readable information which can be used to verify the first item of information,
- wherein the first the second security element, individually or in combination, comprises an optically variable element, and
- wherein the optically variable element adjoins the second item of information or a further item of information and overlaps the first item of information at least in areas, or wherein the optically variable element adjoins the first item of information and overlaps the second item of information at least in areas, and
- wherein the optically variable element comprises a diffractive structure, a zero-order diffraction structure, a blazed grating, a macrostructure, a lens structure or microprism structure, a mirror surface, a matte structure, a volume hologram or a thin-film structure with color-change effect.
A security document with a first security element, which comprises a first item of visually recognizable and machine-readable information, and a second security element, which comprises a second item of machine-readable information which can be used to verify the first item of information,
- wherein the first and the second security element are arranged adjacent to each other and form a combined security element and at least one of the security elements comprises an optically variable element, and
- wherein the optically variable element comprises a diffractive structure, a zero-order diffraction structure, a blazed grating, a macrostructure, a lens structure or microprism structure, a mirror surface, a matte structure, a volume hologram or a thin-film structure with color-change effect.
A security document with a first security element, which comprises a first item of visually recognizable and machine-readable information, and a second security element, which comprises a second item of machine-readable information which can be used to verify the first item of information,
- wherein the first security element or the second security element in each case have at least two partial areas, wherein, in each case, the first or second item of information is contained or stored in a first partial area and a second partial area, comprising an optically variable element, is provided adjacent to the first partial area or surrounding the first partial area, and
- wherein the optically variable element comprises a diffractive structure, a zero-order diffraction structure, a blazed grating, a macrostructure, a lens structure or microprism structure, a mirror surface, a matte structure, a volume hologram or a thin-film structure with color-change effect.
