作者： Wei, Deyun Deng, Yang Xidian Univ Sch Math & Stat Xian Peoples R China

In this paper, we introduce an invariant wavelet transform with multiple parameters in fractional domain and apply it to watermarking algorithm. First, we propose a new transform called redistributed invariant redundant fractional wavelet transform (RI-RFrWT) based on redistributed invariant integer wavelet transform (RI-IWT) and redundant fractional wavelet transform (RFrWT) which implements the extension of RI-IWT in the fractional domain. When the transform order of RI-RFrWT is 0, it degenerates to RI-IWT and has invariance. Second, RIRFrWT is applied to the proposed optimized watermarking algorithm. This algorithm solves the problem that it is difficult for existing algorithms to show high robustness under both geometric and noise attacks. Third, a secure encryption algorithm based on Logisitic-adjusted-Sine map (LASM) and generalized Arnold transform (GAT) is designed to encrypt the information of watermark. Highly sensitive LASM and multi-parameter GAT improve the security of the watermarking algorithm. To improve the invisibility and robustness of the algorithm, particle swarm optimization (PSO) is also used to simultaneously improve the order of RI-RFrWT and embedding strength. Last, the simulation results demonstrate that the proposed watermarking method outperforms high invisibility, robustness and security. Compared with the relevant literature, it has obvious advantages in invisibility and resistance to geometric attacks and noise attacks.

This paper proposes an adaptive watermarking algorithm for copyright pro-tection that addresses the limitations of existing techniques, including low anti-attack ability, fixed embedding strength, and single watermark size. The algorithm selects loca-tions with rich image information in the four high-frequency sub-bands of an image for watermark embedding, effectively enhancing the robustness of the watermark. To address the issue of watermark algorithms being limited to a single-size watermark image, the pro-posed algorithm adaptively selects the number of watermark embedding blocks based on the size of the watermark image, enabling multi-size watermark embedding. Additional-ly, the improved Arnold algorithm is utilized to encrypt the watermark image, enhancing the watermark's security. Experimental results demonstrate that the proposed algorithm ensures the robustness of the watermarking process while addressing the fixed image size issue, enabling multi-size watermark embedding.

This paper presents a robust video watermarking algorithm MDCS. Its performances and watermark extraction capability in wireless channel with dropped packets were tested. The experimental part of the paper confirmed the possibility of extraction high quality color watermark in function of insertion parameter T. The limit value of the insertion parameter which allows extraction of watermark without errors was determined. The obtained results confirm the MDCS algorithm's resilience to packet loss and recommend it for copyright protection in the event of significant degradation of the video sequence.

A novel color watermarking algorithm based on digital signature is proposed. First, the color host image is split into red, green and blue components. Discrete Wavelet Transform level-3 is performed on blue component to obtain various sub-bands. Next, the cD2 sub-band is decomposed by Singular value decomposition, and the watermark information is embedded into the singular values. Then, the digital signature of the orthogonal matrices is generated, and the digital signature is embedded into subbands cH3 and cV3. Last, a set of common attacks are imposed on the watermarked image to test the performance of the new algorithm. The experimental results show that the new algorithm obtains outstanding imperceptibility and robustness compared to the previous algorithms. Meanwhile, the security of the new algorithm catches a higher level by combing digital signature.

Aiming at the public and fixed frequency points in conventional DFT, this paper design a novel attack method to successfully hack DFT-based audio watermarking scheme based on data mining principals. In order to overcome the drawback, a novel secure audio watermarking scheme based on non-uniform discrete Fourier transform(NDFT) is put forward. In the proposed scheme, the suitable NDFT-domain frequency range for embedding audio watermark is calculated as the compromise of inaudible of Human Auditory System(HAS) and high robustness against common signal processing operations. Theoretical analysis and simulation results show obviously that the proposed scheme can successfully resist the designed attack method. Moreover, it has higher robustness against malicious attack and superior security.

This paper introduces the application of edge detection methods in digital watermarking. Based on the characteristics of Human Visual System, in some watermarking schemes copyright information is embedded into edges or textured areas using edge detection methods. This survey covers the methods of edge detection used in watermarking system. A general model of watermarking embedding device based on edge detection is proposed. The research of determination of watermarking embedding position and strength in those schemes has been done. We give a detail analysis of those based on spatial domain and those based on transform domain. Finally, we point out the next, steps on which we can keep going up, hoping for a better balance between watermarking robustness and perceptibility.

This paper presents a digital watermarking algorithm supporting large-size image, the amount of information embedded is based on the characteristics of the host image and the watermarking image. We use pseudo-random encoder to determine the location of embedding information and the watermarking. The method of processing the embedded information and carrier information is discrete cosine transform. The embedding method is determined by the watermark information and the corresponding host pixel value. In the watermark extraction process, the original image and watermarked image are both needed, and the embedded watermark location is determined by the key. The test results show that this algorithm has strong practicality and safety.

watermarking plays an import role in digital copyright protection. It enables copyright owners to embed invisible watermarks within copies of data before distribution. However, most existing watermarking algorithms for 2D vector maps use either spatial domain methods, e.g., the Least Significant Bit or frequency domain methods, e.g., discrete Fourier transform (DFT), and very few algorithms combine the two domains. In order to improve the robustness of watermarks to against more common attacks, a novel algorithm using a combination of spatial and frequency domains is presented. Both the spatial domain and the frequency domain can be used for watermark embedding. Obviously, the advantages of each method are retained and the disadvantages of each method are offset by complementation. The watermark was also shuffled before embedding. A one-way hash function was used to map the watermark and 2D vector map. By using two different methods, one part of the watermark was embedded into the spatial domain first and another part of the watermark was embedded into the DFT domain. Additionally, the watermark was embedded multiple times. No original map data are required for the watermark extraction procedure. Analysis shows that the distortions of the watermarked data are extremely small, and the algorithm is more robust than methods using a single domain. It can resist the most common attacks, such as vertex insertion and removal, cropping, compression, reordering, and data format conversion attacks. It is also robust against rotation scaling and translation attacks.

In this paper, in terms of requisition of imperceptibility and robustness of watermarking, the coefficient features of Discrete Cosine Transform (DCT) are introduced and a new image watermarking scheme based on Discrete Cosine Transform is proposed. Digital watermark is embedded in original image by subtle perturbations of Discrete Cosine Transform corresponding coefficients. Experimental results show that the proposed watermarking scheme is feasible and simple, the embedded watermarking images have little difference with the original images and the extracted watermark is accurate.
