摘要： The present invention aims to provide a simple and reliable security element into a document, which can be recognized without special equipment. This aim is achieved with a paper or paper-like document with a surface, the surface being provided at least in a partial area with a background layer, wherein at least part of the surface of the document is provided with a security element comprising a series of protuberant structures spaced at regular interval. The protuberant structure creates a relief than can be easily recognized while rubbing the document. Contrarily to watermarks or other stamps, the fact that the structure is spaced at regular interval allows the user to better detect it over random structures. Regular interval does not mean that the space between each protuberant structure is equal. Regular means that each structure has a similar width and each space between the structures has also a similar width.

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. The present invention belongs to the fields of security printing and copy protection of banknotes. It aims at preventing illegal copy and duplication of banknotes by printing a security image on the banknote. A device capable of detecting this security image with one-dimensional signal processing is described. Acquisition and printing devices that contain this detector can perform a quick, on-the-fly analysis of the images that transit through them during their normal course of operations, and refuse to perform their function on an image if it contains the security image. This analysis is fast enough relatively to the normal operation of the device so as to go unnoticed by the user. The security image is incorporated by a bi-level halftone image. The Fourier transform of this halftone image contains a two-dimensional pattern with a circular symmetry that is built by applying a 360-degree rotation to a one-dimensional signal. This one-dimensional signal exhibits a degree of self- similarity across a given range of scale changes. It may be detected by traversing the two-dimensional pattern along a straight line passing through its center.
