The invention relates to a multilayer structure intended to be inserted in an identification document and comprising at least one first layer at least partially opaque forming a data area, the first layer comprising at least one through opening integrally confined by at least partially opaque material of the first layer, and a second layer at least partially transparent extending at least partially on the data area in order to extend into the through opening, the second layer comprising a part extending beyond the first layer and forming an edge part, the second layer comprising at least one element forming a security element, the security element being present and/or visible on and/or in the edge part and in the through opening of the first layer.

A method for building a security image for a security structure of a security document from multiplexing color images, including selecting a marking method capable of producing sets of colors on the security document comprising different colors that can be displayed according to illumination/observation modes of the security structure, establishing a plurality of color sets that can be displayed by the security structure in a plurality of the different illumination/observation modes, distributing the color sets in a plurality of groups of color sets, establishing combinations of groups of color sets having at least one color set in common across the number of different illumination/observation modes, selecting a combination of a group of color sets based on the number of desired illumination/observation modes and the number of colors per color image, and determining the color images to multiplex by means of the combination of the group of color sets selected.
