A method for implementing a personalized augmented reality associated to carrier means, wherein said method comprises: - receiving at input an optical image of said carrier means; - incorporating an information content in said optical image in such a way that said information content is hidden in said optical image, where said information content is customizable; - decoding said information content; and - reproducing said information content through an electronic device, wherein said reproduction enables implementation of said augmented reality; said method envisaging, after said incorporation and prior to said decoding, the step of transferring said optical image onto said carrier means, wherein the latter may comprise a physical medium, in particular in the form of paper or fabric, or else a digital medium, such as a display of an electronic device, wherein said incorporation of the information content in said optical image comprises: - receiving at input said information content (102.1); - if said optical image is not square, rendering said optical image square (102.2) so as to obtain a square image; - transforming said square image with the discrete Fourier transform (102.3) to obtain a transformed square image, wherein said transformed square image is formed by a first, magnitude-matrix, channel and by a second, phase-matrix, channel; - generating a plurality of data matrices, wherein each of said matrices is a binary square matrix (104A, 104B); - dividing each of said data matrices into two triangular semi-matrices (D1, D2) (102.4); - introducing each of said triangular semi-matrices (D1, D2) within said first, magnitude-matrix, channel of said transformed square image (102.5) at a distance (d, d) from the constant Fourier coefficient to obtain a modified first, magnitude-matrix, channel (M'), said distance (d, d) varying in a predefined way for each pair of triangular semi-matrices (D1, D2), in such a way that each pair of semi-matrices does not overlap with the other pairs of semi-matrices during the step of introduction into said modified first, magnitude-matrix, channel M'; and - after said introduction, carrying out the inverse transform of said modified first, magnitude-matrix, channel (M') together with said second, phase-matrix, channel to obtain said optical image in which said information content has been incorporated. - receiving at input an optical image of said carrier means; - incorporating an information content in said optical image in such a way that said information content is hidden in said optical image, where said information content is customizable; - decoding said information content; and - reproducing said information content through an electronic device, wherein said reproduction enables implementation of said augmented reality; - receiving at input said information content (102.1); - if said optical image is not square, rendering said optical image square (102.2) so as to obtain a square image; - transforming said square image with the discrete Fourier transform (102.3) to obtain a transformed square image, wherein said transformed square image is formed by a first, magnitude-matrix, channel and by a second, phase-matrix, channel; - generating a plurality of data matrices, wherein each of said matrices is a binary square matrix (104A, 104B); - dividing each of said data matrices into two triangular semi-matrices (D1, D2) (102.4); - introducing each of said triangular semi-matrices (D1, D2) within said first, magnitude-matrix, channel of said transformed square image (102.5) at a distance (d, d) from the constant Fourier coefficient to obtain a modified first, magnitude-matrix, channel (M'), said distance (d, d) varying in a predefined way for each pair of triangular semi-matrices (D1, D2), in such a way that each pair of semi-matrices does not overlap with the other pairs of semi-matrices during the step of introduction into said modified first, magnitude-matrix, channel M'; and - after said introduction, carrying out the inverse transform of said modified first, magnitude-matrix, channel (M') together with said second, phase-matrix, channel to obtain said optical image in which said information content has been incorporated.
