Abstract
The invention relates to a security material comprising a carrier and at least one photochromic Protein and/or a mutein of a photochromic protein.

The inventive security material is also characterized in that it is highly forgery-proof, the photochromic biomolecule cannot be removed therefrom in a usable form, and the photochromic biomolecule does not need to be supplied to a large group of clients.
