A security document (10) includes a security feature (3) with a hologram (7) and a color image (6) arranged on top of each other. Holographic features (27) of the hologram (7) are visible when the security document (10) is viewed under white light, and a plurality of image features (26) of the color image (6) are visible when the document (10) is viewed under UV light. The image features (26) are perfectly aligned with the holographic features (27). This can be achieved, for example, by providing one or more registration marks when forming the holographic features, and using said registration marks to later print the color image (6).

Physical identification tags are provided that contain patterns of magnetized and non-magnetized nanoparticles embedded in a matrix. The magnetic nanoparticles form a spatially unique magnetic field distribution that is detectable only with the use of a quantum scanning magnetometer with nanometer resolution. The invisible magnetic field pattern is randomly generated by the mixture of magnetic with nonmagnetic nanoparticles and is physically impossible to reproduce. The tags can be used for identification and authentication of articles of commerce, artworks, and subjects.
