Abstract (en)
[origin: WO2015197499A1] The invention relates to a set (100) of documents (10, 10', 10", 10''') for transmitting data in a spy-proof manner. Each document (10, 10', 10", 10''') of the set (100) has a first sheet with an interference pattern (1; 1'; 1''; 1''') and a second sheet which is designed to be written with data. The interference pattern (1; 1'; 1''; 1''') of the first sheet is produced such that the interference pattern hinders an unauthorized reading or spying of the data of the second sheet when the second sheet and the first sheet are lying one on top of the other. The interference pattern (1; 1'; 1''; 1''') of each of the documents (10, 10', 10'', 10''') of the set (100) is an individual interference pattern which differs from the interference patterns (1, 1', 1'', 1''') of all the remaining documents (10, 10', 10", 10''') of the set (100).
