“…While extraction, the two watermarks are compared with the original watermarks and the one whose similarity is higher is adopted as the required watermark. A dual digital watermarking technology for digital rights management is presented in [12], in this paper, the first watermark for copyright protection of the owner is embedded in the low and middle frequency of Discrete Cosine Transform coefficients of the cover image. The second watermark belongs to the customer is embedded in the DC coefficients.…”

Dual digital watermarking has emerged as a successful solution for copyright protection, tamper detection and localization. However, several problems related to the robustness, capacity, tampered area detection still mystifying. This paper presents a high capacity dual watermarking mechanism for digital color image. An invisible robust watermark is embedded in the Green component of the host image by using a hybrid combination of Stationary Wavelet Transform (SWT) and Singular Value Decomposition (SVD) for copyright protection. A fragile invisible watermark based on the Least Significant Bit (LSB) replacement approach is embedded in the Blue component of the image for tamper detection and localization. The proposed technique focuses on robustness and imperceptibility while maximizing embedding capacity that makes this technique a multipurpose watermarking scheme.

“…multichannel watermarking. Also embedding two different watermarks containing information about the owner of the image and the client using the digital image may be deemed as parallel watermarking [27]. An example of a sequential algorithm may be the use of the DWT transform to initially process the image, and then to embed the mark represented in the DCT frequency domain [21].…”

“…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.
