“…Therefore, there is a strong need for developing techniques which can help to identify intellectual property of digital documents [1]. Digital Watermarking is one of possible technologies which can be used for protecting intellectual property of digital content [2][3][4][5]. The research performed by the author, published in [6] has demonstrated that there is no commercial software nor technology which satisfies all requirements of robust digital watermarking.…”

“…In practical applications Discrete Cosine Transform (DCT), Discrete Fourier Transform (DFT), Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) are used. Most authors focus on a single watermark embedding scheme in a single domain and compare the scheme with a traditional one, usually in the same domain [3,4,7]. As a result, it is very difficult to determine which watermark embedding scheme performs actually best in terms of robustness and how much the embedding domain influences the robustness of the scheme.…”

Abstract. Recently, a variety of digital watermarking schemes have been developed for copyright protection of digital images. In robust watermarking, which is used in copyright protection, transform-based algorithms are used to ensure resilience of the watermark to common signal processing attacks. The most frequently used watermarking algorithms for additive watermark embedding involve DCT, DFT, SVD and DWT domains. In this article we verify which domain is optimal for robust, the additive watermark embedding scheme. We demonstrate that in additive watermark embedding the embedding domain plays more important role than the embedding formula.

“…Fragile algorithms aim at discovering and locating the changes introduced in a watermarked picture [18]. The aim of semi-fragile al-gorithms is to detect and locate the area which has been changed in the watermarked picture, at the same time providing sufficient robustness so that the additional information is not removed by the most basic image processing (such as [8,31]).…”

“…In addition, imperceptible methods may be further divided into those which use the perceptual models of a human being [4,55]-the Watson model may be given as an example [16,43]. There are many methods which do not take into account the perceptible models [9,17,18,27].…”

The protection of copyrights of digital images authors is one of the most important tasks set before watermarking. What is especially important is to ensure the high robustness of a watermarked images against attacks, preventing the reading of additional information about the author. In addition, the used processing of the original image must be absolutely invisible. The presented algorithm embeds information in a parallel way-independently of the luminance and chrominance matrices in the spatial and frequency domains. The main factor motivating the use of a parallel watermark embedding via the proposed way was the mutual complementing of robustness, offered by processing in spatial and frequency domains. Additional information is recovered in a 2D cepstrum domain and in coefficients of the cosine transform. The article shows a description of a mathematical model, tests of invisibility, effectiveness and the robustness of the method were carried out. The robustness of the algorithm was shown against the following attacks: JPEG and JPEG2000 lossy compression, noise, median filtering, Low-Pass and High-Pass filtering, desynchronization, simple and inverse D/A conversion, majority cropping, photomontage and affine transforms-rotation, scaling, shearing, translation.
