BANKNOTES WITH A PRINTED SECURITY IMAGE THAT CAN BE DETECTEDWITH ONE-DIMENSIONAL SIGNAL PROCESSING |
摘要 |
The present invention aims to propose a method to generate a security pattern to be embedded in an original image having the particularity that the detection of the security pattern can be achieved through a simple, low processing capability device. The present invention proposes a method for generating a security image comprising an original image and a security pattern, characterized in that the security pattern has the form of a grating in which the lines width and/or the line spacing is modulated to embody a predefined data, the security image is generated by the modulation of at least one color of at least a part of the original image with the grating. |
