The invention relates to a security element comprising a carrier substrate comprising a transparent or translucent area carrying at least one digitised mark made of at least one set of dots appearing as a three dimensional mark when viewed in transmitted light. The invention relates to a security support or document or article comprising the said security element and to the method of identification and/or authentication of this security support or document or article.

Security element having a digitised mark and security support or document comprising same

The invention relates to a method for securing a colored or uncoloured translucent or opaque object (), in which a sticker () is affixed to the back of the object (), said sticker comprising: a substrate including a watermark or pseudo-watermark () which is sufficiently transparent to allow the object () to be seen through the watermark or pseudo-watermark (); and a luminescent agent which is positioned at least partially over the watermark or pseudo-watermark () between the watermark or pseudo-watermark () and the object ().

Method for securing a coloured opaque object

A security paper comprising a fibrous substrate comprising a watermark having repeating motifs, and a security structure that does not completely cover the watermark and has at least one semi-reflective area which is superposed at least partly on the watermark; which paper on the one hand allows observation, through the semi-reflective area, at least partially, of one of the motifs, and on the other hand allows observation at least partially of another of said motifs in a region of the watermark that is not covered by the security structure.

Security paper

A security structure intended to be incorporated or fastened, at least partially, in or on an article, for example a security document and/or a document of value, includes at least one first fluorescent zone capable of emitting by fluorescence, under a predefined illumination condition, visible light of a first color; and at least one second fluorescent zone capable of emitting by fluorescence, under the predefined illumination condition, visible light of a second color that differs from the first, the first and second fluorescent zones being observable from the respective opposed faces of the structure.

Security structure and article incorporating such a structure

The present invention relates to a security document and/or document of value comprising:

Security document and/or a document of value

The present invention relates to printable security paper that includes a region capable of receiving printed indicia on the front side and on the reverse side which are observable in reflected light and form an image observable in transmitted light, as security element protecting against two-sided copying, characterized in that such region is a screened region having an average overall opacity less than the opacity of the vellum part of the rest of the paper, said screened region being made up from alternations of vellum miniregions, having an approximately constant thickness equal to that of the vellum part of the rest of the paper, and of miniregions of reduced opacity because of their smaller thickness compared with the vellum miniregions. The invention also relates to the security document obtained with this paper.
