- the secure article and the other object are bank notes, especially with the same fiduciary value.
- the article secure and the other object can then be differentiated from each other only by a serial number for example.
- the revealed images each having a certain proportion of each nested image it is understood that the revelation frame reveals a certain proportion of each of the nested images of the combined image to form the revealed image.
- the proportion of a nested image is between 0 and 1, the value 0 being assigned to a nested image when the latter is not a component of the revealed image, that is to say when the latter is completely obscured by the revelation frame and the value 1 being assigned when the entirety of the nested image is a component of the revealed image, that is to say when the latter is not the same. all obscured by the weave of revelation.
- All elements of all the nested images and / or the revelation frame may be composed of one or more micromotives. This makes it possible to reinforce the security of the secured article, the micromotif being for example observed using a magnifying glass and constituting a level 2 security.

- the one or more nested image elements and / or the revelation screen may each be composed of several micromotives, in particular a micropod repeating periodically in one or more directions over the entire dimension of the element according to this or these directions. .
- micromotives of an element can form a continuous appearing line, especially when observed with the naked eye at a normal viewing distance.
- normal observation distance is meant the usual observation distance of a secure article, for example 30 cm and preferably 15 cm.
- all the elements of the same nested image are composed of the same micromotif, in particular of a micropod repeating periodically in one or more directions over the entire dimension of the elements according to this or these directions.
- the micromotives have at least one dimension less than or equal to 1 mm, better less than or equal to 100 ⁇ , more preferably less than or equal to 50 ⁇ .
- the micromotives are not apprehensible to the naked eye and the nested image elements and / or frame appear homogeneous.
- the color of the nested picture elements and / or the revelation frame depends on the color of the micropatterns composing them. Red-colored micromotives form red-colored elements that appear uniform.
- the micromotives are of different colors, so that the elements belonging to different interleaved images are of different colors, each of the elements having for example the color of the microparticles composing it.
- ⁇ * 94 according to the CLE. 1994 greater than or equal to 2, preferably greater than or equal to 3.
- color is defined by the combination of three parameters of hue, saturation and brightness.
- the hue is the perception of the color measured on a color wheel
- the saturation is the purity of the color
- the brightness is the degree of lightening or darkening of a color.
- the micromotives are of different hues, so that the elements belonging to different nested images are of different hues, each of the elements having for example the hue of the microparticles composing it.
- the micromotives belonging to different nested images may be different in their aspects, in particular their shapes, and / or their hues, opacities, saturations, luminescence or gloss, and / or may present a contrast, in particular a contrast of saturation, of intensity, hue and / or luminance, and / or a color difference sufficient to distinguish, especially under white light, two adjacent imbedded image elements when observed with a certain magnification, for example with a magnifying glass.
- ⁇ * 94 according to the CLE. 1994 greater than or equal to 2, preferably greater than or equal to 3.
- the colors of the micromotives can be primary colors or not.
- the micromotives can be fluorescent and have different aspects, including different colors, under UV light.
- Micromotives can be luminescent.
- the micromotives can be represented as positive or negative.
- Each nested image element and / or revelation frame may comprise a bottom on which the micromotor or micromotives are made.
- the nested and / or raster image elements are lines, and the nested and / or raster image lines each consist of a micropat repeating itself periodically over their entire length.
- the micromotives are substantially of the same width / as the line of nested images and / or weft they compose, in particular a width / less than or equal to 1 mm, better than or equal to 100 ⁇ , and even better less than or equal to 50 ⁇ .
- the combined image comprises a periodic alternation of nested image elements in one or more directions.
- the combined image may comprise at least two nested images, preferably at least three.

- the article 10 comprises several different second images 120, as can be seen for example in FIG. 11, and the electronic imager 100 produces one or more first images 110.
- the electronic imager 100 produces one or more first images 110.
- the electronic imager 100 may display one or more indicators 140a, 140b, 140c and 140d for informing the user on how to position the article 10 shown in Fig. 28 relative to the imager.
- the indicators 140a to 140d can make it possible to know where to position the upper right corner of the article 10, so as to superimpose correctly a second image 120 of an article 10 to a first image 110a, 110b, 110c or l 10d displayed on the electronic imager 100 screen.
- Article 10 may comprise an integrated microcircuit 152, for example a chip
- RFID or optical for communicating with the electronic imager 100 to control the display of an indicator as described above or to disseminate information on how to position the first and second images.
- the chip 152 is able to communicate with the electronic imager 100 to enable the first image 110 associated with the second image 120 to be produced.
- the second image 120 is illuminated with the electronic imager 100.
- the chip 152 includes information transmitted to the electronic imager 100 which projects or then displays the first image 110 based on this information.
- Article 10, in particular the second image 120 can be photographed and / or filmed by a digital camera belonging to or connected to the electronic imager 100.
- a recognition program can then make it possible to recognize the second image 120 and to acquire from a database a first image 110 associated with the second image 120.
- the database is for example stored on a secure server.
- the first image 110 thus obtained is displayed and / or projected by the electronic imager 110 to allow authentication and / or identification of the article 10.
- the electronic imager 100 is in the form of a mobile phone on which a first image 110 is displayed in the form of a combined image I.
- Article 10 comprises a polarizing filter on which a the second image 120 is formed as a revelation screen 4.
- the article 10 comprising the second image 120 in the form of a revelation screen 4 is superimposed on the first image 110 in the form of a combined image I produced by the electronic imager 100, this emitting a polarized light.
- the article 10 comprising the revelation screen 4 can be displaced by a translation movement along the axis X relative to the combined image I displayed by the screen of the electronic imager 100, so as to change the the revealed images I r .
- Such a method makes it possible to authenticate and / or identify the security article 1 according to several security levels.
- the positioning of the revelation screen 4 comprising the polarizing filter according to the orientation making it possible to observe the opacity of the polarizing filter, this observation being visible only on a screen emitting polarized light, for example an LCD-type screen, provides a first level of security.
- the electronic imager 100 is a screen, in particular of the LCD type, comprising a plurality of pixels preferably forming a combined image, for example as described in FIG. 30 A.
- the invention is not limited to the illustrated examples.
- the secure article can be made with other first, second or third level security, for example.
