摘要: The invention relates to a security element composed of a final picture, the spatial frequencies of which comprise a hidden picture, and the final picture has the form of a matrix of sub-pictures, created from the matrix with the hidden picture after the thresholding, consisting of at least two color pixels arranged such that, when reading in the frequency space, the hidden picture is presented, where every pixel in the matrix with the hidden picture after the thresholding is mapped with a particular sub-picture, and all the pixels of the same color included in the matrix with the hidden picture after the thresholding are mapped with the same sub-picture. The invention also relates to a data carrier on/on which a security element is placed.
