identification document with an enhanced anti-forgery element

摘要

The invention relates to an identification document comprising a see-through portion (10) having a first side (S1) and a second side (S2), said see-through portion comprising first personalized information (11), said identification document being made so that the see-through portion enables to visualize different personalized information from its both sides, in such a manner that it becomes impossible for an infringer either to modify the personalized information or to remove the see-through portion and to replace it by another completely falsified see-through portion. For that, the first personalized information (11) comprises a second personalized information (12), which is hidden into it when viewed from the first side (S1), a filtering device (16) is attached on the second side (S2) of the see-through portion (10), in order to reveal the hidden second personalized information (12), which appears superimposed onto the first personalized information (11) when viewed from said second side (S2), while it remains hidden when viewed from the first side (S1).
