A feature substance is provided for securing the authenticity of documents of value, having at least one luminescent substance in particle form and nanoparticles enveloping the surfaces of the luminescent substance particles at least partially, wherein the properties of the feature substance result from the interaction of the properties of the luminescent substance and of the nanoparticles. The invention furthermore relates to a method for producing the feature substance, a method for securing the authenticity of a security element or document of value using a feature substance, as well as security elements and documents of value with authenticity features on the basis of the feature substance.

A visibly transparent, homogeneous UV-blocking cellulose nanocrystal/lignin nanocomposite film and a method of making the same. The film is made by dispersing cellulose nanocrystals and lignin in an aqueous, alkaline solution to yield a dispersion; casting the dispersion onto a substrate; and evaporating the aqueous, alkaline solution to yield a homogeneous, visibly transparent film that at least partially absorbs ultraviolet (UV) radiation.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obtaining information to be embedded within an identification document. Modifying the information to add depth when viewed through a three-dimensional (3D) viewing device, thereby yielding modified information. Embedding the modified information in a target image to yield a modified target image such that the modified information is not viewable to a naked eye and the modified information is visible with added depth when viewed through a 3D viewing device. Disposing the modified target image on an identification document to yield embedded 3D information. An identification document includes the target image and 3D information embedded within the target image. The 3D information embedded within the target image is not visible to a naked eye, but is visible with added depth when viewed through a 3D viewing device.
