Abstract:
A method for secure transmission and visualization of encrypted information. A first grid of first and second element types is applied to a first medium. The types differently modify a property of light through the medium. A key defined by element distribution is determined. A second grid with different light-modifying element types is applied to a second medium. A second-grid contoured area defines an information item. Second-grid elements are distributed such that a first-grid element of the second type corresponds to a second-grid element of the first type, a first-grid element of the first type corresponds to a second-grid element of the second type outside the area, and a first-grid element of the second type corresponds to a second-grid element of the second type, and a first-grid element of the first type corresponds to a second-grid element of the first type inside the area. Grid superimposition makes the information visible.
