TL;DR: This paper presents a new dual watermarking scheme based on DWT-SVD which is able to withstand a variety of attacks and is a gray scale meaningful logo instead of randomly generated Gaussian noise type watermark.
Abstract: In the recent years, digital watermarking is used for copyright protection and authentication. In this paper, a new dual watermarking scheme based on DWT-SVD is presented to improve the robustness and protection. Both discrete wavelet transform (DWT) and singular value decomposition (SVD) have been used as a mathematical tool to embed watermark in the image. In the proposed technique, two watermarks are embedded in the host image. First watermark is called primary watermark, which is a gray scale digital image. Second watermark is called secondary watermark which is a gray scale meaningful logo instead of randomly generated Gaussian noise type watermark. The secondary watermark is embedded into primary watermark and the resultant watermarked image is used as watermark for the host image. A reliable watermark extraction scheme is developed for the extraction of the primary as well as secondary watermark from the distorted image. Experimental evaluation demonstrates that the proposed scheme is able to withstand a variety of attacks. The secondary watermark is easy to detect in all the cases but sometimes primary one is severely distorted.

TL;DR: A novel watermarking technique is proposed using a region-adaptive approach to further improve upon criteria and shows the robustness of the watermark data to image processing attacks and geometric attacks is improved, validating the earlier hypothesis.
Abstract: Despite the progress in digital image watermarking technology, the main objectives of the majority of research in this area remain to be the improvement in robustness to attack. In this paper, a novel watermarking technique is proposed using a region-adaptive approach to further improve upon criteria. Watermark data is embedded on different regions of the host image using a combination of Discrete Wavelet Transform and Singular Value Decomposition techniques. The technique is derived from an earlier hypothesis that the robustness of a watermarking process can be improved by using watermark data which frequency spectrum not dissimilar to that of the host data. To facilitate this, the technique utilises dual watermarking technologies and embed parts of the watermark images into selected regions in the host image. Our experiment shows our technique has improved the robustness of the watermark data to image processing attacks and geometric attacks, thus validating the earlier hypothesis.

TL;DR: In the proposed system, a Dual Watermarking Scheme based on DWT SVD with chaos encryption algorithm, will be developed to improve the robustness and protection along with security.
Abstract: Digital Watermarking is used for copyright protection and authentication. In the proposed system, a Dual Watermarking Scheme based on DWT SVD with chaos encryption algorithm, will be developed to improve the robustness and protection along with security. DWT and SVD have been used as a mathematical tool to embed watermark in the image. Two watermarks are embedded in the host image. The secondary is embedded into primary watermark and the resultant watermarked image is encrypted using chaos based logistic map. This provides an efficient and secure way for image encryption and transmission. The watermarked image is decrypted and a reliable watermark extraction scheme is developed for the extraction of the primary as well as secondary watermark from the distorted image.

TL;DR: A scheme based on DWT and Singular Value Decomposition (SVD) and modified DWT coefficients of the cover image with the singular values of the visual watermark allows the development of a watermarking scheme that is robust to a wide range of attacks.
Abstract: As watermarking is identified as a major technology to achieve copyright protection, the relevant literature includes several distinct approaches for embedding data into a multimedia element. Because of its growing popularity, the Discrete Wavelet Transform (DWT) is commonly used in recent watermarking schemes. In a DWT-based scheme, the DWT coefficients are modified with the data that represents the watermark. In this paper, we present a scheme based on DWT and Singular Value Decomposition (SVD). After decomposing the cover image into four bands (LL, HL, LH, and HH), we apply the SVD to watermark, and modify DWT coefficients of the cover image with the singular values of the visual watermark. Modification in all frequencies allows the development of a watermarking scheme that is robust to a wide range of attacks.

TL;DR: The experimental results prove that using different strength values increases the robustness of the watermark with little sacrifice in image quality and demonstrate the effectiveness of the scheme for the origin verification as well as the tamper detection.
Abstract: This paper presents an image authentication scheme that can verify the origin of the received image and, moreover, detect if the image has been tampered with. The underlying technologies of the scheme are digital watermarking and image secret sharing. Different from other schemes that use one piece of watermark information for one purpose and a different piece for another, the watermark information used for original verification is also utilized for tamper detection. Moreover, unlike other schemes that employ a fixed strength value for embedding watermarks, the scheme automatically utilizes two different strength values, one for flat regions and the other for complex regions. The experimental results prove that using different strength values increases the robustness of the watermark with little sacrifice in image quality. The results also demonstrate the effectiveness of the scheme for the origin verification as well as the tamper detection.

TL;DR: To improve the robustness and protection of watermarking schemes, the combination of DWT and SVD are used to achieve high robustness against different types of attacks like cropping, resizing, rotation etc.
Abstract: Several watermarking schemes have been widely used to solve the copyright protection problems of the image. In this paper, to improve the robustness and protection, two watermarking schemes are presented. First watermarking scheme is single level watermarking in which we embed the watermark into cover image in RGB space. Second watermarking scheme is dual watermarking scheme in which two watermarks are embedded in the host image. For both watermarking schemes, we used Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) Mathematical tools. The combination of DWT and SVD are used to achieve high robustness against different types of attacks like cropping, resizing, rotation etc.

TL;DR: A novel watermarking algorithm based on singular value decomposition (SVD) is proposed and results show that the newwatermarking method performs well in both security and robustness.
Abstract: Digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia documents in networked environments. There are two important issues that watermarking algorithms need to address. First, watermarking schemes are required to provide trustworthy evidence for protecting rightful ownership. Second, good watermarking schemes should satisfy the requirement of robustness and resist distortions due to common image manipulations (such as filtering, compression, etc.). In this paper, we propose a novel watermarking algorithm based on singular value decomposition (SVD). Analysis and experimental results show that the new watermarking method performs well in both security and robustness.

TL;DR: This work presents a watermarking procedure to embed copyright protection into digital audio by directly modifying the audio samples and introduces the notion of a dual watermark: one which uses the original signal during detection and one which does not.
Abstract: We present a watermarking procedure to embed copyright protection into digital audio by directly modifying the audio samples. Our audio-dependent watermarking procedure directly exploits temporal and frequency perceptual masking to guarantee that the embedded watermark is inaudible and robust. The watermark is constructed by breaking each audio clip into smaller segments and adding a perceptually shaped pseudo-random sequence. The noise-like watermark is statistically undetectable to prevent unauthorized removal. Furthermore, the author representation we introduce resolves the deadlock problem. We also introduce the notion of a dual watermark: one which uses the original signal during detection and one which does not. We show that the dual watermarking approach together with the procedure that we use to derive the watermarks e⁄ectively solves the deadlock problem. We also demonstrate the robustness of that watermarking procedure to audio degradations and distortions, e.g., those that result from colored noise, MPEG coding, multiple watermarks, and temporal resampling.

TL;DR: A new multiresolution watermarking method based on the discrete wavelet transform (DWT), where Pseudo-random codes are added to the large coefficients at the high and middle frequency bands of the DWT of an image.
Abstract: We introduce a new multiresolution watermarking method for digital images. The method is based on the discrete wavelet transform (DWT). Pseudo-random codes are added to the large coefficients at the high and middle frequency bands of the DWT of an image. It is shown that this method is more robust to often proposed methods to some common image distortions, such as the wavelet transform based image compression, and image halftoning. Moreover, the method is hierarchical. The computation load needed to detect the watermark depends on the noise level in an image.

TL;DR: This paper proposes a wavelet-tree-based blind watermarking scheme for copyright protection that embeds each watermark bit in perceptually important frequency bands, which renders the mark more resistant to frequency based attacks.
Abstract: This paper proposes a wavelet-tree-based blind watermarking scheme for copyright protection. The wavelet coefficients of the host image are grouped into so-called super trees. The watermark is embedded by quantizing super trees. The trees are so quantized that they exhibit a large enough statistical difference, which will later be used for watermark extraction. Each watermark bit is embedded in perceptually important frequency bands, which renders the mark more resistant to frequency based attacks. Also, the watermark is spread throughout large spatial regions. This yields more robustness against time domain geometric attacks. Examples of various attacks will be given to demonstrate the robustness of the proposed technique.

TL;DR: An overview of wavelet-based watermarking techniques available today can be found in this paper, where the authors provide an overview of the wavelet wavelet transform domain and its application in image compression.
Abstract: In this paper, we will provide an overview of the wavelet-based watermarking techniques available today. We will see how previously proposed methods such as spread-spectrum watermarking have been applied to the wavelet transform domain in a variety of ways and how new concepts such as the multi-resolution property of the wavelet image decomposition can be exploited. One of the main advantages of watermarking in the wavelet domain is its compatibility with the upcoming image coding standard, JPEG2000. Although many wavelet-domain watermarking techniques have been proposed, only few fit the independent block coding approach of JPEG2000. We will illustrate how different watermarking techniques relate to image compression and examine the robustness of selected watermarking algorithms against image compression.
