Reversible data hiding has attracted more and more attention in recent years. With reversible data hiding, it requires embedding secret data into original image with devised algorithm at the encoder, and marked image can then be delivered to the decoder. At the decoder, both the secret data and original image should be perfectly separated from marked image to keep the reversibility. There are several...
In this paper, we propose a binary value based progressive image watermarking approach for digital right protection. The proposed method embed most watermark information into region of interest(ROI) of an image. Therefore, a client on Internet can decode the watermark while receiving the image, moreover, most watermark information would be decoded while the ROI of the image is received. In order to...
Progressive transmission of multimedia can be commonly encountered in multimedia communications. In this paper, we develop the reversible data hiding scheme for ownership protection of color images, which is suitable to meet the characteristics of progressive transmission. With progressive transmission, data can be partitioned into base and enhancement layers. We consider carefully altering the difference...
Reversible data hiding has emerged in recent years, and it has the fundamental requirement of reversibility. For reversible data hiding, secret information is embedded into original image with devised algorithms, and the marked image should be delivered to the decoder without any damage. For decoding, both the embedded secret and original image should be recovered perfectly. With these characteristics,...
Hiding data into images can be referred to as a constrained optimization problem. Hence, we proposed a reversible genetic watermarking scheme based on the wavelet packet transform in this paper. Genetic algorithm is used to select an appropriate basis from permissible bases of wavelet packet transform to increase the robustness of the embedded data, and the binary string to be hidden is embedded into...
In this paper, we propose a genetic watermarking method for stereoscopic images. A stereoscopic image is stored as two images and combined by software while displayed. Thus, a pirate can only clip half of the image to remove the embedded watermark. To prevent the watermarks from being removed, the proposed watermarking method embeds an identical watermark into two half images of a stereoscopic image,...
Lossless data hiding belongs to one major branch in information security researches. The major goal is to retain the lossless property of proposed algorithm, meaning that original image and embedded secret should be perfectly recovered at decoder. Based on the multi-round prediction of differences between original and marked images, enhanced amount of capacity can be obtained while retaining the acceptable...
Reversible data hiding is a newly developed topic in watermarking researches. At the encoder, it relies on slightly modifying the characteristics of original images for embedding secret information. At the decoder, original image and secret information can be separated from marked image with slight amount of overhead. In this paper, we propose the scheme by predicting the difference between output...
This paper proposes a novel scheme that considers the data hiding with sub sampling and compressive sensing. We utilize the characteristics of compressive sensing, sparsity and random projection, to embed secret data in the observation domain of the sparse image obtained through compressive sensing. The high bit correction rate (BCR) in experiments shows the high accuracy of our proposed method.
Reversible data hiding is one of the popular topics in watermarking researches, and it belongs to the branch of digital rights management (DRM) applications. Similar to conventional watermarking techniques, for reversible data hiding, at the encoder, secret information can be embedded into original images, and the marked image can be obtained. Different from conventional watermarking, due to the term...
In this paper, we propose a digital watermarking method for stereoscopic video frames. A stereoscopic video frame is stored as two images and combined by software while displayed. These two stored images are with high similarity. On the other hand, a pirate can only clip half of a frame to remove watermarks. In the circumstances, it should be taken into consideration to resist collusion attacks and...

After reception...
In this paper, we proposed a coevolutionary multi-objective genetic watermarking scheme based on the wavelet packet transform. Wavelet packet transform can be viewed as a generalization of the discrete wavelet transform and a best wavelet basis in the sense of some cost metric can be found within a large library of permissible bases. Coevolutionary multi-objective genetic algorithm is used to select...

In this method, a video clip is embedded with v Gaussian watermarks and then scrambled and multi casted from a content server to U clients. A BIBD-based methodology is applied to determine the needed number (v) of sub keys for a total of U clients. In the mean time, the server also decomposes...

For decoding, original image and secret information need to be perfectly recovered from the received image...
In recent years, Camera Smart phone has become a popular consumer electronics product. Young people like to use that to record their daily lives, moreover, they will share these photos and information to others. However, the photos may be used without consent after they are uploaded to Internet. To avoid this problem, one can embed visible and invisible watermarks into images. However, an additional...
