“…Reversible data hiding [1][2][3][4][5][6][7][8][9][10], often referred to as reversible watermarking, was proposed as a promising technique for sensitive image (such as medical and remote sensed images) authentication, and it has drawn much attention in the recent years. Such an embedding algorithm allows extraction of intact hidden data from the watermarked digital carriers and lossless recovery of the original images, if no modification has been made to the watermarked digital carriers.…”

“…Afterwards, a number of reversible data hiding techniques have been developed, and the methods can be classified into two main categories by different data embedding domains. One category applies data embedding in the spatial domain [1][2][3][4], with relatively low capacity. The other category hides data into the coefficients in the transform domains [5][6][7][8][9], such as the integer DCT and the integer wavelet transform domains.…”

In this paper, we present a progressive reversible data hiding technique by symmetrical histogram expansion in the transform domain of Piecewise-Linear Haar (PLHaar). Data are embedded into the PLHaar coefficients of images progressively from the pivotal bin of a histogram of PLHaar coefficients to both sides of the pivot symmetrically. With PLHaar, no overflow or underflow occurs to the pixel values, and our data hiding method achieves the highest embedding capacity with PSNR around 50dB compared to the previous methods in the literature. The method can also be applied to artificial images with an exactly flat histogram, which is impossible for a method to hide data in the spatial domain. The progressiveness of the proposed method also enables a rough but automatic capacity-PSNR control. The effectiveness of our method is demonstrated with a number of experiments.

“…Some lossless watermark methods have been proposed for images [1,2,3]. In [1], Fridrich et al presented a method which is based on losslessly compressing some selected bit-plane to "make some space" for the embedded bits.…”

“…In [1], Fridrich et al presented a method which is based on losslessly compressing some selected bit-plane to "make some space" for the embedded bits. In [2], Vleeschouwer et al proposed to map the image gray levels to the points on the circle; watermark embedding and image reversion correspond to rotation of the vector that points to the gray level mass center.…”

An Adaptive Scalable Watermark Scheme for High-Quality Audio Archiving and Streaming Applications

In this paper, we present a scalable (i.e. lossy-to-lossless) watermark scheme based on a recently standardized scalable audio coder -AAZ [4]. The proposed framework enables the recovery of the original lossless audio after watermark embedding, and in the meanwhile, is able to make the watermark adaptive such that the watermark distortion to the lossy host audio is minimized. An encryption mechanism is further employed for restricting unauthorized access to lossless audio and watermark removal. Based on this framework, we elaborate its possible applications on high-quality audio archiving and streaming. Experimental results demonstrate the validity of our proposal.

As advanced melanoma remains practically incurable, early surgical excision is an important step toward a reduction in mortality. For that, the dermatologists always encouraged the detection of the nevus at an early stage. In recent years, a considerable interest has arisen in the development of noninvasive tools to improve early diagnosis, many new technical operation using a telecommunication network allow practitioners to perform in real time a relevant diagnosis. Because of the open environment of web-based applications, their exploitation in medical field introduces many security concerns. In this article, we present DECOPREME (COllaborative PREcocious DEtection of Melanoma) a new project which allows practitioners to use telecommunication technologies to provide early diagnosis. We describe, after that, our proposed reversible watermarking method used for integrity verification, we also evaluate image visual quality after watermark embedding and the effectiveness of locating tampered regions.
