摘要

Decodificau00e7ao reflective device for use in decodificau00e7ao a scrambled image, object autenticavel and method of forming a reflective decodificau00e7ao device for use in decodificau00e7ao a scrambled image decoding device is provided for reflective Use in decoding a coded image, comprising a latent image is encoded.Using at least one parameter coding. The device comprises a substrate with a portion of the reflective surface having a topography of the surface comprising a predetermined pattern of topographic aspects.The predetermined pattern is configured with at least one geometric feature, corresponding to at least one parameter coding so that placing a sheet of light transmitting, and the scrambled image formed on it through the predetermined pattern of aspec These topographical allows the latent image is visualized.
