1. A method of disseminating an encoded message, comprising:

  • printing a two-dimensional selectively readable barcode onto an article, said two-dimensional barcode employing a two-color encoding scheme;

    said two-dimensional barcode having;

    a data area that consists of a QR encoded message and a quiet zone surrounding said data area that enables an ordinary scanning device to locate said data area;

    said data area embodied within an area defined by four corners diametrically opposite one another, and having three finder patterns located at the top left, top right and bottom left corners of three corners of said four corners of said data area, said three finder patterns serving to determine an orientation of said two-dimensional selectively readable barcode to enable a reading of said two-dimensional selectively readable barcode;

    removing a section of said two-dimensional selectively readable barcode at said fourth corner of said data area;

    thenencoding a Reed-Solomon standard error correction code new message at said fourth corner of said data area;

    replacing said removed section at said fourth corner of said data area of said two-dimensional selectively readable barcode with said new message to form a damaged region wherein said damaged, region consists of a distractor pattern comprising a fourth finder pattern and a cluster of confusing alignment patterns to form a peacocked code (pQR), said distractor pattern comprising said peacocked code (pQR) functioning to confuse said ordinary scanning device thereby interfering with said ordinary scanning device'"'"'s ability to decode an encoded message on said two-dimensional selectively readable barcode on said article;

    wherein replacing said removed section with said new message to form a damaged region containing said peacocked code (pQR) expands a search space of the said two-dimensional selectively readable barcode while concurrently rendering said QR code unscannable; and

    wherein expanding said search space of said QR code increases a read time of said QR code by the scanning device and reducing said search space of the QR code decreases the read time of the QR code;

    then,occluding said distractor pattern containing said peacocked code (pQR) in said damaged region from the purview of said ordinary scanning device, by placing an object between said ordinary scanning device and said distractor pattern to prevent an image of said damaged region from being viewed by said ordinary scanning device, with the result that said ordinary scanning device obtains an image of only a non-damaged QR barcode area,wherein occluding said distractor pattern containing said peacocked code (pQR) damaged region of said non-damaged QR barcode area from said purview of said ordinary scanning device reduces said search space of said, two-dimensional selectively readable QR barcode, thereby decreasing an amount of time for scanning said QR barcode below a scanning duration of said scanning device.
