A label (1) with protection against forgery comprises an unclonable security feature (10) and a hidden code (20). The hidden code (20) contains data describing the security feature (10). The data are coded in the hidden code in the form of characters (21). As a result, the characteristic properties of the security feature (10) are directly stored on the label (1), with the result that it is not necessary to access a database in order to authenticate the security feature (10). The characters (21) may be arranged on a substrate (30) with a covering layer (60) above which is opaque when illuminated with light in the visible spectrum and transparent when illuminated with light in at least one part of the invisible spectrum (for example transparent and readable with an infrared camera in the infrared spectral range), or which becomes transparent when heated above a temperature threshold value (for example made of thermochromic inks).

The invention relates to a security feature for safeguarding a value document. The security feature is formed on the basis of a luminescent substance which, in its pure form, has a different excitation behavior than in a diluted form when used in the value document, and the luminescent substance is based on an inorganic host lattice, which is doped with Mn(V) as a luminophore. The proportion of the Mn(V) substance in the luminescent substance is less than 2%, and the host lattice of the luminescent substance is selected from apatites of the type A5(PO4)3Z, spodiosites of the type A2PO4Z, and phosphates of the type A3(PO4)2, wherein A = Ca, Sr, Ba and the mixtures thereof and Z = F, CI, OH and the mixtures.
