A robust digital watermarking adopting 2D barcode

In this paper, a new watermarking algorithm using 2D barcode is proposed. The 2D barcode means 2-dimensional barcode that contains more information than conventional 1-dimensional barcodes. For error correction, 2D barcode allow the recognition of barcodes that are up 60% damaged. Therefore, the 2D barcode as watermark can be survived when it used in highly noisy environment. In this paper, a new wavelet based watermarking algorithm using 2D barcode as watermark is proposed. Dynamically generated 2D barcode is inserted as watermark in wavelet domain. From the experimental result, the proposed algorithm shows better invisibility and robustness comparing with the conventional methods using plain image as watermark.
