Abstract
The invention relates to a fraud-proof document comprising a carrier and at least one marking arranged on the carrier, wherein at least a part of the surface of the marking or along at least a part of the periphery of the marking a weakening pattern is arranged in the carrier which, when detached, results in a permanent an easily visible distortion of the pattern. When removing the glued-on passport photo or foil a forger will irrevocably distort the weakening pattern, this such that the regularity is permanently and visibly disturbed so that it is easy to ascertain that the document in question has been subjected to an attempted fraud.
