Streszczenie:

This article presents an advanced dual chaotic watermarking scheme to improve information security. To ensure confidentiality in digital image transmission, a secure dual watermarking scheme is proposed by applying the chaotic logistic system and hyper-chaotic dynamical system. Chaotic watermarking was conducted in the spatial domain, where suboptimal secure hashing with a variable length was selected in preprocessing stages. The secret key was generated by the chaotic sequence for pixel shuffling using a chaotic logistic map, so that a controlled amount of distortion was inserted into the host digital image. Watermarking was proceeded after the chaotic watermark had been embedded into the shuffled image. To strengthen the security, the hyper-chaotic system was used to generate chaotic blocks for block scrambling in order to achieve dual chaotic watermarking. Characteristics analysis was conducted for multiple examples in both spatial and frequency domains. Potential effects induced by the chaotic driving parameter on processing time and integrity authentication of chaotic dual watermarking were also analyzed in detail.

The single watermark algorithms always merely have single function. In order to overcome the drawback, this paper proposed a dual video watermarking scheme based on transform domain. To implement the video copyright and integrality authentication, this paper embedded robust watermarking and fragile watermark. At the same time, this scheme made good use of the wavelet transform to embed the two different kinds of watermarking in the same video respectively. The fragile watermarking is to serve the robust watermarking. Experiments demonstrate this scheme can not only protect the copyright of the video effectively, but also protect against some attacks, such as shearing attack, JPEG lossy compression attack, noise attack etc. This scheme has better robustness and invisibility.

Streszczenie:

Nowadays, multimedia applications are extensively utilized and communicated over Internet. Due to the use of public networks for communication, the multimedia data are prone to various security attacks. In the past few decades, image watermarking has been extensively utilized to handle this issue. Its main objective is to embed a watermark into a host multimedia data without affecting its presentation. However, the existing methods are not so effective against multiplicative attacks. Therefore, in this paper, a novel quantum-based image watermarking technique is proposed. It initially computes the dual-tree complex wavelet transform coefficients of an input cover image. The watermark image is then scrambled using Arnold transform. Thereafter, in the lower coefficient input the watermark image is embedded using quantum-based singular value decomposition (SVD). Finally, the covered image is obtained by applying the inverse dual-tree complex wavelet transform on the obtained coefficients. Comparative analyses are carried out by considering the proposed and the existing watermarking techniques. It has been found that the proposed technique outperforms existing watermarking techniques in terms of various performance metrics.

Watermarking is a method to digitally sign a product to provide authentication and prevent copyright infringement to proving the ownership of a product and provides integrity for companies to protect their product. In this study, dual layer watermark that applies two different watermarking techniques at each layer is presented. The first layer applies the LSB Substitution technique while the second layer uses the Discrete Wavelet Transform (DWT) technique. This implies greater integrity as it contains of two signatures in providing authentication.

Streszczenie:

Digital watermarking is important for the copyright protection of electronic data, but embedding watermarks into vector maps could easily lead to changes in map precision. Zero-watermarking, a method that does not embed watermarks into maps, could avoid altering vector maps but often lack of robustness. This study proposes a dual zero-watermarking scheme that improves watermark robustness for two-dimensional (2D) vector maps. The proposed scheme first extracts the feature vertices and non-feature vertices of the vector map with the Douglas-Peucker algorithm and subsequently constructs the Delaunay Triangulation Mesh (DTM) to form a topological feature sequence of feature vertices as well as the Singular Value Decomposition (SVD) matrix to form intrinsic feature sequence of non-feature vertices. Next, zero-watermarks are obtained by executing exclusive disjunction (XOR) with the encrypted watermark image under the Arnold scramble algorithm. The experimental results show that the scheme that synthesizes both the feature and non-feature information improves the watermark capacity. Making use of complementary information between feature and non-feature vertices considerably improves the overall robustness of the watermarking scheme. The proposed dual zero-watermarking scheme combines the advantages of individual watermarking schemes and is robust against such attacks as geometric attacks, vertex attacks and object attacks.

The more we are concerned about copyright protection of digital image, the more eagerly we are seeking technologies that promise to keep from pirated copy and tampering. Since digital image watermarking has the potential to fulfill this need, it has become an important research topic for the past decades. A dual-domain dual-watermark (DDDW) scheme based on human visual system and spread spectrum technique is proposed in the thesis for the purpose of owner identification and digital signature. One watermark is visual and embedded into the spatial domain for owner identification and the other is an invisual watermark embedded into the discrete wavelet transform (DWT) domain for digital signature. The former also has an aliasing in the DWT domain to enhance its robustness. When retrieving the watermarks, the detector does not require the original image but four private keys. The experimental results show that high normalized correlations (NC) exist between the embedded and extracted watermarks. Even after an attack, e.g. JPEG compression, JPEG2000 compression, clipping, etc, the extracted watermarks of the proposed scheme are still robust.

This paper proposes a dual digital watermark scheme based on visual cryptography; two share images, which produced by visual secret sharing scheme, are used in this research; one is kept by owner; the other one is hidden in the middle-frequency components using the traditional Discrete Cosine Transform (DCT) that preserves the quality of the protected images. When verifying the copyright, the original images can be restored by applying the decryption rules of rotating share image and image differentiation method to the extracted hidden share image and copyright holder’s share image. This research shows the proposed technique achieves dual copyrights with characteristics.

Internet makes our life more convenient, but with that comes some weaknesses: such as easy duplication and the counterfeit; therefore, the intelligence proprietary protection becomes a critical issue. The digital watermarking technology can be used to prevent these weaknesses from occurring; also, most multimedia can have multiple ownerships, so, it’s a necessity to have dual copyright. This research proposes a dual audio watermarking technology that combines visual cryptography technology and Fast Fourier transform (FFT). The process transforms the audio into a frequency domain by FFT, then, uses the visual cryptography to generate two share images from two digital watermarking, then, embeds one share image into the frequency coefficients of the audio, finally, applies the inverse Fast Fourier transform (IFFT) to complete the dual watermarked audio design. When verifying the ownership, the share image can be extracted from the watermarked audio and verified the dual watermarking by applying the visual cryptography.

Abstract 　To date the most commonly used technique is the DCT-based JPEG. However, JPEG compressed images at low bit rates will result in block effects. The next generation for image compression standard is the wavelet-based JPEG2000. JPEG2000 also provides for new functionality like the ROI (Region of Interest). In this paper, we propose the ROI watermarking embedded scheme in JPEG200. 　There are three positions in JPEG200 coding flow for information hiding. The first is after the images transform the image data are transformed to wavelet coefficients. For the digital watermarking, the payload is usually low, and multiple embedding with the majority detection or the spread-spectrum concept can be applied. The second hiding location is after quantization .And last hiding location is embedded in the output of tier-2 coding, it can be guaranteed that all the embedded information will be received without error and in a correct order because we avoid the two major sources of information loss. 　In this paper, we proposed a hybrid watermarking scheme to embed and extract based on the JPEG2000 Codec. Our scheme mix spatial domain watermarking (W1 embedded in gray-level coefficients before JPEG2000 compression) and frequency domain watermarking (W2 embedded in ROI coefficients after quantization). Distortion reduction technique was used on image to lessen image degradation caused by embedding. This kind of scheme is robust to attacks like cut-and-paste, mean filter, luminance, and more.

Streszczenie:

The availability of versatile multimedia processing software and the far-reaching coverage of the interconnected networks have facilitated flawless copying, manipulations and distribution of the digital multimedia (digital video, audio, text, and images). The ever advancing storage and retrieval technologies have also smoothed the way for large-scale multimedia database applications. However, abuses of these facilities and technologies pose pressing threats to multimedia security management in general, and multimedia copyright protection and content integrity verification in particular. Although cryptography has a long history of application to information and multimedia security, the undesirable characteristic of providing no protection to the media once decrypted has limited the feasibility of its widespread use. For example, an adversary can obtain the decryption key by purchasing a legal copy of the media but then redistribute the decrypted copies of the original .In response to these challenges; digital watermarking techniques have been proposed in the last decade. Digital watermarking is the procedure whereby secret information (the watermark) is embedded into the host multimedia content, such that it is: (1) hidden, i.e., not perceptually visible; and (2) recoverable, even after the content is degraded by different attacks such JPEG compression, noise, horizontal and vertical flips etc. The two basic requirements for an effective watermarking scheme, imperceptibility and robustness, conflict with each other. The main focus of this thesis is to provide good tradeoff between perceptual quality of the watermarked image and its robustness against different attacks. For this purpose, we have discussed a robust digital watermarking technique in discrete wavelet (DWT) domain. This scheme employs a contrast sensitivity based human visual system (HVS) model. The iv HVS models give us a direct way to determine the maximum strength of watermark signal that each portion of an image can tolerate without affecting the visual quality of the image. The proposed work develops a novel approach of embedding both visible and invisible watermarks into cover image. Visible watermark is used only to distract the hacker /unauthorized user as actual watermark is inserted invisibly. This increases the security two fold as visible watermark act as copyright logo and invisible serves the purpose of authentication. This is carried out by embedding primary watermark visibly using alpha blending and the DWT coefficients of the host image have been modified for embedding invisible secondary watermark. The proposed approach incorporates both blind and non blind methods into one watermarking scheme and work well on grayscale as well as color images. Performed objective and subjective analysis proves the efficiency of proposed approach.

In this study, we propose a complete architecture based on digital watermarking techniques to solve the issue of copyright protection and authentication for digital contents. We apply visible and semi-fragile watermarks as dual watermarks where visible watermarking is used to establish the copyright protection and semi-fragile watermarking authenticates and verifies the integrity of the watermarked image. In order to get the best tradeoff between the embedding energy of watermark and the perceptual translucence for visible watermark, the contrast-sensitive function (CSF) and noise visible function (NVF) of perceptual model is applied which characterizes the global and local image properties and identifies texture and edge regions to determine the optimal watermark locations and strength at the watermark embedding stage. In addition, the perceptual weights according to the basis function amplitudes of DWT coefficients is fine tuned for the best quality of perceptual translucence in the design of the proposed watermarking algorithm. Furthermore, the semi-fragile watermark can detect and localize malicious attack effectively yet tolerate mild modifications such as JPEG compression and channel additive white Gaussian noise (AWGN). From the experimental results, our proposed technique not only improves the PSNR values and visual quality than other algorithms but also preserves the visibility of the watermark visible under various signal processing and advanced image recovery attacks.

The low-frequency DCT coefficients of an image are relatively insensitive to geometric processing. In this paper, the low-frequency DCT coefficients of a full DCT domain are divided into several blocks, and the mean of the coefficients of each block is temporally modulated based on the watermark information bits. This method can embed watermark information both in space and time domain, and achieves the goal of blind detection and incremental of watermark information. The experimental results show that the proposed method is robust against rotating, cropping, scaling, filtering, and compressing attacks.
