Redistributed invariant redundant fractional wavelet transform and its application in watermarking algorithm

EXPERT SYSTEMS WITH APPLICATIONS 2025年 262卷

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.

Digital watermarking is the process of embedding unnoticeable information into digital multimedia content like digital spatial data such that the information can later be detected or extracted for a variety of purposes including copy prevention and control. In this paper, a new watermarking algorithm for remote sensing image based on fast curvelet transform was proposed. Firstly, the original remote sensing image was decomposed into curvelet coefficients by fast curvelet transform. Then, the proper positions were chosen to embed an image watermark in the curvelet coefficients taking into account the impact of the variation of the curvelet coefficients and the Human Visual System (HVS). Finally, the inverse fast curvelet transform was performed with the modulated curvelet coefficients and got the watermarked remote sensing image. The experiments indicated that this algorithm enabled the watermarking to have the very good invisibility and made the watermarking have very strong robustness to the general geometric attacks like JPEG compression, noise, filter and cropping and so on.

Digital watermarking technology is a very good method for protecting copyright. 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. Moreover, it is imperceptible and robust against various signals processing such as noise adding, cropping, rotating and sharp, etc.

This paper presents a novel blind video watermarking method based on image complexion analysis. The image complexion information is extracted from the DC coefficient in sub blocks transformed by discrete cosine transform (DCT) to make sure the macroblock of image adapt to be embedded watermark information. Subsequently, the algorithm presents DCT coefficients space layered mode (DCSLM), and embeds watermark in the intermediate frequency AC coefficients according to DCSLM and some rules. Watermark detection can be done without the original video. Therefore, it is blind detection. Ultimately, image which has been embedded watermark show the proposed algorithm has favorable imperceptible. Simulation results show the proposed watermarking algorithm has strong robustness against some attacks such as JPEG compression, noise attack, frame statistical average and so on.

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.

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 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.

In this paper, we proposed an Binary Image watermarking algorithm Based on SVD and used AES algorithm with KEY, because this type of watermark has stronger impact during the copyright reclamation moment, compared with the use of a pseudo random pattern generated by a secret key as watermark code. The proposed algorithm is evaluated from the transparency point of view and the robustness against some common attacks, such as a JPEG compression, filtering, noise corruption and cropping.

Combined with one-way Hash function, the parity of block DCT coefficients and JPEG quantization technology, etc, this paper proposes a new algorithm: image watermarking algorithm resistant to copy attack. This algorithm uses PN sequence encryption to ensure the security of watermark and blind extraction when recovering watermark, some common attack experiments of image processing verify the performance of watermark generated through this algorithm. Compared with those algorithms which need to use original images to recover data, this algorithm is more practical and it has very good robustness and transparency.
