2D barcodes as watermarks in image authentication

Abstract


  • 2D barcodes are increasingly used as tags in every

    type of goods for unique identification. Compared with

    the 1D barcodes, 2D barcodes not only can carry more

    data but also can withstand errors in subsequent

    scans. This property has significant parallels to

    watermarking logos as such watermarks will withstand

    multiple manipulations that are common with image

    transactions. We use a 2D Barcode as the watermark

    as this has error correction capabilities and show that

    this can be used to insert data imperceptibly into the

    host image. One Barcode is inserted into the low

    frequency component of the image and a second

    Barcode watermark is embedded into low pass

    component of any wavelet decomposition at a specific

    level only known to the author. This improves the

    resistance of the watermarking scheme to attack. Our

    experimental results indicate that these invisible

    watermarks can carry significant information and are

    robust to many image manipulations.
