Inspired by a recently proposedconstructive framework for the distributed source coding problem [1], we propose a powerful constructive approach to the watermarking problem, emphasizing the dual roles of distributed source coding with side information at the decoder and channel coding with side information at the encoder. In our framework, we explore various source and channel codes to close th...

Reversible watermarking that not only protects the copyright but also preserve the original quality of the digital content have been intensively studied. In particular, the demand for reversible watermarking has increased. In this paper, we propose a reversible watermarking scheme based on interpolation-error shifting and error pre-compensation. The intensity of a pixel is interpolated from the...

We propose a novel robust audio watermarking algorithm in time domain that uses perceptually tuned ISS method and attack characterization at the embedding side. Attack characterization is used for prediction of distortions in the watermark channel in order to improve watermark detection reliability. The proposed algorithm has decreased bit error rate in comparison with the watermarking system t...

Digital watermarking is extensively used in ownership authentication and copyright protection. In this paper, we propose an efficient thresholding scheme to improve the watermark embedding procedure in an image. For the proposed algorithm, watermark casting is performed separately in each block of an image, and embedding in each block continues until a certain structural similarity threshold is...

This paper presents the high-capacity blind text watermarking algorithm that is robust to print and scan operations and this method based on the odd-even quantization. First, segment the binary images of Chinese text characters. And the text image is segmented into the embedded part, adjust part, and dislodge part. After segmentation, the quantization function is built on the basis of invariabl...

Reversible watermark is a kind of fragile watermark, and any changes will lead to the change or loss of watermarking information. The modified sensitivity of reversible watermark can be used for the integrity verification of grid map. When the content of carrier data is suspected, the type of manipulation or attack suffered can be judged through extracting the watermarking situation. The revers...

The last decade has shown tremendous growth data production from different sectors, e.g., biology, financial markets, scientific computing, business processes, Internet of Things. The “Data is New Oil” has become a proverb in academic and corporate circles. Accordingly, tracing, recording origin and deriving data called data provenance has gained tremendous traction across board. Privacy and se...

Multiple image watermarking is an advanced concept of singular techniques. The existing digital techniques cannot obtain all the design goals, such as imperceptibility, robustness, security, and capacity simultaneously with perfection. Hence, multiple technique designed that embeds several watermarks into same host for conveying information. This paper proposed a Discrete Cosine Transform (DCT)...
