A system generates a secure barcode by the following steps of: identifying a primary pattern for a two-dimensional barcode to be printed on a substrate, wherein the primary pattern comprises a set of dark cells and a set of light cells; identifying a two-dimensional micro-shape, wherein the micro-shape has a size which is not larger than a size of each cell of the two-dimensional barcode; generating a secondary pattern comprising a plurality of micro-shapes; and superimposing the secondary pattern with the primary pattern for the two-dimensional barcode to generate a secure barcode. The formed two-dimensional barcode comprises the primary pattern comprising the set of dark cells and the set of light cells, where the sets represent encoded data, and the secondary pattern of the micro-shapes which are superimposed with the primary pattern. |
