Embodiment Construction

[0047] exist figure 1 In , a section consisting of lines of a guilloche pattern is seen with a partial area in which the lines are demarcated. The line width in this figure is 30 μm, the width of the formed void (b Z ) is about 10 μm. exist figure 2 Identify the encoded information within the gap. The coded information is formed by Morse lines which in turn have a width of 10-20 μm or double that. Double line width can be used, for example, to illustrate the separation between individual symbols or characters.

[0048] The value document and / or security document according to the invention can be produced, for example, by generating a symbol as a checksum from the serial number of the value document and / or security document and assigning it to the value document and / or security document. document. This symbol or sequence of symbols is then converted to a sequence of adjacent lines depending on the type of Morse code or barcode. Subsequently, a guilloche pattern is gene...

Abstract

The invention relates to a value and / security document (1) having at least one line (3), for example in the form of a guilloche pattern, wherein the line has a line width (b), wherein the line (3) is divided at least In a partial region ( 4 ), a cutout (Z) with a width (bz) is produced, wherein the first information is coded in the cutout (Z) and wherein the cutout (Z) is not visible to the naked eye.

Description

technical field [0001] The invention relates to a document of value and / or a security document having one or more lines, in particular a guilloche pattern, characterized in that at least a partial area of ​​at least one of the lines is configured such that a The spaces in which information is encoded, the invention also relates to a method for producing such a document and a method for reading information from one or more lines. Background technique [0002] Different methods of protecting value and / or security documents against forgery are known in principle from practice. On the one hand, these methods include security features that cannot be reproduced or can only be reproduced with relatively high effort, such as graphic displays formed from a large number of thin lines. These graphic displays include, inter alia, guilloche patterns. In connection with the guilloche pattern, it is known that the guilloche pattern is formed in such a way that it is formed at least in a ...
