    摘要： A method for authenticating and/or identifying a security article that includes a transparent or translucent substrate and, on a side of a first face of the substrate, a first image. The method includes superimposing at least partially the first image of the article with a second image. The second image may be produced by an electronic imager. The second image may be situated on the side of a second face of the substrate that is opposite to the first face. The method permits observation of an authentication and/or identification information item of the security article during a change of the angle of observation of the first and second superimposed images.
