ABSTRACT:
The security object comprises a substrate, a surface structure and a hologram layer. A volume hologram is arranged in the hologram layer. The hologram layer is deformed in homogeneously by the surface structure, which gives rise to readily detectable changes in the reflections from the volume hologram. These changes can be used to verify the authenticity of the object. The surface structure can e.g. be applied using intaglio printing techniques or embossing. Alternatively or in addition to the deformation of the hologram layer by means of the surface structure, the hologram layer may also be deformed by embossing.
