Nowadays, commercial activity on Internet and media requires a protection by increasing security. The 2D Barcode with a digital watermark is a widely interest research in security field. QR Code with invisible watermark prevents information hiding text. This paper proposes QR Code (Quick Response Code) that is embedded an invisible video watermark by using Discrete Multiwavelet transformation (DMT). We have developed an optimization technique using the genetic algorithm to search for optimal quantization step in order to improve both quality of watermarked video and robustness of the watermark. This technique does not require the original image in the watermark extraction. The experimental results show that the proposed watermarking algorithm yields watermarked image with good imperceptibility and very robust.
