Efficient Reversible Watermarking Based on Adaptive Prediction-Error Expansion and Pixel Selection

IEEE Transactions on Image Processing, 2011
Prediction-error expansion (PEE) is an important technique of reversible watermarking which can embed large payloads into digital images with low distortion. In this paper, the PEE technique is further investigated and an efficient reversible watermarking scheme is proposed, by incorporating in PEE two new strategies, namely, adaptive embedding and ...

Comparison of reversible watermarking usingprediction error expansion and prediction error expansion considering region of interest for medical images

2017 2nd International Conference for Convergence in Technology (I2CT), 2017
The major distinguishing features used to assess a data hiding technique are distortion and embedding capacity. This paper presents a comparison between classical Prediction error expansion based reversible watermarking and proposed prediction error expansion scheme considering region of interest for grayscale medical images.

Reversible watermarking by prediction-error expansion

6th IEEE Southwest Symposium on Image Analysis and Interpretation, 2004., 2004
We propose a new reversible (lossless) watermarking algorithm for digital images. Being reversible, the algorithm enables the recovery of the original host information upon the extraction of the embedded information. The proposed technique exploits the inherent correlation among the adjacent pixels in an image region using a predictor.

Reversible data hiding using additive prediction-error expansion

Proceedings of the 11th ACM workshop on Multimedia and security, 2009
Reversible data hiding is a technique that embeds secret data into cover media through an invertible process. In this paper, we propose a reversible data hiding scheme that can embed a large amount of secret data into image with imperceptible modifications. The prediction-error, difference between pixel value and its predicted value, is used to embed a

Reversible Data Hiding for Audio Based on Prediction Error Expansion

2008 International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2008
This paper proposes a reversible data hiding method for digital audio using prediction error expansion technique. Firstly, the prediction error of the original audio is obtained by applying an integer coefficient predictor. Secondly, a location map is set up to record the expandability of all audio samples, and then it is compressed by lossless ...

Reversible watermarking of 3D mesh models by prediction-error expansion

2008 IEEE 10th Workshop on Multimedia Signal Processing, 2008
In this paper, a reversible watermarking algorithm is proposed for 3D mesh models based on prediction-error expansion. Firstly, we predict a vertex position by calculating the centroid of its traversed neighbors. Then the prediction error, i.e. the difference between the predicted and real positions, is expanded for data embedding.

Reversible watermarking based on multi-dimensional prediction-error expansion

Multimedia Tools and Applications, 2018
The reversible watermarking algorithm has been extensively studied in the field of information security in recent years, and prediction-error expansion (PEE) is a widely used technology for reversible watermarking embedding. Ou et al. (IEEE Trans Image Process 22(12):5010–5021, 2013) proposed a two-dimensional histogram shifting method to extend the ...

Reversible Watermarking Based on Adaptive Prediction Error Expansion

2019
In traditional prediction error expansion (PEE) based reversible watermarking (RW), the watermark bits are embedded into the two peaks of the global prediction error histogram. This scheme ignores some bins in local histogram. To improve the utilization of prediction error, a method based on locally adaptive PEE is proposed.

Error-free Authentication Watermarking Based on Prediction-Error-Expansion Reversible Technique

24th IET Irish Signals and Systems Conference (ISSC 2013), 2013
Watermarking technology is an efficient method to protect multimedia content. In this paper, an error-free authentication watermarking is proposed based on prediction-error-expansion reversible technique. A binary image is used as an au- thentication watermark, and embedded in the prediction errors block-wise.

Efficient reversible image watermarking by using dynamical prediction-error expansion

2010 IEEE International Conference on Image Processing, 2010
Reversible watermarking is a special watermarking technique which allows one to extract both the hidden data and the exact original signal from the watermarked content. In this paper, a recently introduced reversible image watermarking method based on prediction-error expansion is further investigated and improved.
