Progressive barcode

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.

1. A method of progressively encoding independently encrypted security data elements within a barcode in a simultaneous multiple security application, the method comprising:
encoding information of a first data element within the barcode using a layout of black modules and encoding information of a second data element within the barcode using a layout of color modules; and, progressively modifying the barcode by generating a new layout of the black modules or of the colored module or both, wherein the new layout is related to the first data element or second data element or both.
