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.

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.
