This paper proposes a tamper detection and correction technique using semi-fragile data hiding that aims to achieve high perceptual quality of images at the user-end even after malicious modifications. A binary signature and an image digest are embedded by modulating integer wavelet coefficients using dither modulation based quantization index modulation. Half-toning technique is used to obtain image digest from the low-resolution version of the host image itself. Decoder extracts the binary signature from the watermarked image for tamper detection, while the extracted image digest is used to correct the tamper region. Unlike previously proposed techniques, this novel approach distinguishes malicious changes from various common image processing operations more efficiently and also correct tapered regions effectively. Experimental results show that the proposed technique provides a superior performance in terms of probability of miss and false alarm as well as in tamper correction, compared to several existing semi-fragile watermarking techniques.

This paper proposes an active steganalysis method for quantization index modulation (QIM)-based steganography. The proposed nonparametric steganalysis method uses irregularity (or randomness) in the test image to distinguish between the cover image and the stego image. We have shown that plain quantization (quantization without message embedding) induces regularity in the resulting quantized object, whereas message embedding using QIM increases irregularity in the resulting QIM-stego. Approximate entropy, an algorithmic entropy measure, is used to quantify irregularity in the test image. The QIM-stego image is then analyzed to estimate secret message length. To this end, the QIM codebook is estimated from the QIM-stego image using first-order statistics of the image coefficients in the embedding domain. The estimated codebook is then used to estimate secret message. Simulation results show that the proposed scheme can successfully estimate the hidden message from the QIM-stego with very low decoding error probability. For a given cover object the decoding error probability depends on embedding rate and decreases mono-tonically, approaching zero as the embedding rate approaches one.

In this paper, we present a novel application of Quantum Particle Swarm Optimization (QPSO) in the field of medical image watermarking for copyright protection and authentication. The trade-off between the imperceptibility and robustness is one of most serious challenges in digital watermarking system. To solve the problem, image watermarking can be considered as an optimization problem by utilizing human visual system (HVS) characteristics and QPSO algorithm in adaptive quantization index modulation and singular value decomposition in conjunction with discrete wavelet transform (DWT) and discrete cosine transform (DCT). Experimental results prove the effectiveness of the proposed algorithm that yields a watermarked image with good visual fidelity, at the same time watermark able to withstand a variety of attacks including JPEG compression, Gaussian noise, Salt and Pepper noises, Gaussian filter, median filter, image cropping and image scaling.

A method is proposed for resisting averaging attacks, in which many users collude to make an average image in which the watermarked information is canceled out. This method works by minutely and uniquely changing the original image for each user (purchaser), which degrades the quality of the average image. A basic experiment showed that the greater the number of images degraded, the more effective the proposed method. Another experiment showed that the method is more effective when images with large distortion parameters are combined. © 2012 IEEE.

In this paper, our main purpose is to embed data in the frequency domain of audio signals. Data was embedded by means of quantization index modulation (QIM) in the frequency domain. With this aim, the spectrum of the audio signal was divided into two parts. The first part consisted of the first 19 Barks and the second included the remaining 6 Barks. Each of these parts had a different quantization step size. In order to have large quantization step sizes which yield more robustness, Human Auditory System (HAS) has been used. Decoder detects the watermark signal, without using the original audio signal. Simulation results have shown that this watermarking scheme has better robustness against some common attacks, such as white Gaussian noise, echo, filtering, and MP3 compression, than similar approaches in the time and wavelet domains with the same computational complexity.

Video data hiding is still an important research topic due to the design complexities involved. We propose a new video data hiding method that makes use of erasure correction capability of repeat accumulate codes and superiority of forbidden zone data hiding. Selective embedding is utilized in the proposed method to determine host signal samples suitable for data hiding. This method also contains a temporal synchronization scheme in order to withstand frame drop and insert attacks. The proposed framework is tested by typical broadcast material against MPEG-2, H.264 compression, frame-rate conversion attacks, as well as other well-known video data hiding methods. The decoding error values are reported for typical system parameters. The simulation results indicate that the framework can be successfully utilized in video data hiding applications.

Biometric secret-key binding inherently requires signal processing and error correction schemes due to noisy measurement readings. Two previously proposed strategies, quantization index modulation (QIM) andWyner-Ziv (WZ) coding, are studied in the context of biometric key binding. We characterize the tradeoff between key rate-leakage and key rate-reconstruction distortion, showing that while WZ coding has a better rate-leakage tradeoff than QIM, the latter has a better rate-reconstruction tradeoff. A new strategy is proposed to combine the merits of these schemes. Known as distortion-enhanced Wyner-Ziv coding (DE-WZ), this scheme is demonstrated to exhibit improved flexibility based on numerical results for a uniform source model and scalar quantization.

This paper presents two JPEG steganographic methods using quantization index modulation (QIM) in the discrete cosine transform (DCT) domain. The two methods approximately preserve the histogram of quantized DCT coefficients, aiming at secure JPEG steganography against histogram-based attacks. In comparison with F5 as a representative JPEG steganography, the proposed methods show high performance with regard to embedding rate, PSNR of stego image, and particularly histogram preservation.

According to the correlation between adjacent blocks of the carrier image， two algorithms, called STDM-COMW and STDM-PCO-MW, are proposed. By using the quantization step calculated from the previous secondary block to modulate the latter secondary block, STDM-CO-MW solves the problem of the difference of quantization step between embedding and decoding. In order to raise the correlation between adjacent secondary blocks, STDM-PCO-MW exchanges the pixels between the previous secondary block and the latter one before *** a result STDM-PCO-MW is more robust. Thanks to the quantization step calculated above based on modified Watson model , we find that the quantization step of our algorithms varies linearly with the brightness of the carrier image adaptively .From the results of numerical simulation, it is obvious that our proposed algorithms are robust to JPEG compression, Gaussian noise and gain attack. Compared with AQIM and general STDM based on Watson model, our algorithms have a great improvement in performance.

Block-Based Watermarking for Color Images Using Visibility of quantization Noise

Color images are believed to be more ideal for watermark embedding than grayscale images, because color images provide more space for hiding data. Robustness and transparency of the embedded watermark are required by image watermarking for copyright protection. A feasible solution of taking advantage of color signals in the design for color image watermarking is to effectively exploit the properties of the human visual system. This article proposes a block-based watermarking scheme that is based on the visibility of quantization noise of the color signal. The block-based scheme selects perceptually significant portions in the wavelet subband of luminance and chrominance components for robust watermark insertion and embeds the watermark with maximum distortion allowed for transparent watermarking. The strategy is to use the noise detection thresholds of color signals in the color image. By using the noise detection thresholds of wavelet coefficients in the color image, the blocks with high energy can be located and the strength of the watermark can be appropriately determined for watermark embedding. Binary watermark signals are embedded in the coefficients of perceptually significant blocks by quantization index modulation. Simulation results show that the proposed watermarking scheme for color images is robust to malicious attacks while retaining watermark transparency. The performance of the proposed scheme is even better than that of the existing color watermarking method that hides the watermark in the DC components of the DCT domain of color images.
