摘要:
A method and apparatus for encoding, in a simultaneous multiple security application, independently encrypted security data elements within a single matrix of blocks in a progressive barcode. The method and apparatus including, encoding information of a first data element within the matrix using black modules and, encoding information of a second data element within the matrix using color modules. The barcode being configured to be overprinted as it progresses through progressive states. The progressive barcode, resulting from the overprinting through the progressive states, masking the ability to conclusively determine the barcode in a previous state.
