Abstract:

  Digital Watermarking is a technology used for securing digital content, that is, images, audio, and video sequences. Watermarking is useful in various ways and can be used as an effective deterrent against copyright theft of photographs, maps, paper bank notes, stock certificates and other illustrations. This work is based on digital still image watermarking in the discrete wavelet transform (DWT) domain by image/logo fusion and analyses the effects of compression, particularly, JPEG and JPEG2000 on watermarked images. It was required to achieve imperceptible watermarking that would not degrade image quality and that would be robust against compression. Watermarking and compression are two conflicting ideas in that the former adds extra bits of information while the latter removes bits from an image. However, since watermarked images are compressed prior to transmission or storage, it is important to ensure that the digital watermark is robust against compression.
