Reversible Data Hiding Method for Interpolated Images Based on Modulo Operation and Prediction-Error Expansion

Reversible data hiding based on prediction error expansion using adjacent pixels

For some applications such as satellite and medical images, reversible data hiding is the best solution to provide copyright protection or authentication. Being reversible, the decoder can extract the hidden data and recover original image without distortion. In this paper, a reversible data hiding scheme based on prediction-error expansion is proposed. The predictive value is computed by using...

Optimal Histogram-Pair and Prediction-Error Based Reversible Data Hiding for Medical Images

In recent years, with the development of application research on medical images and medical documents, it is urgent to embed data, such as patient's personal information, diagnostic information and verification information into medical images. Reversible data hiding for medical images is the technique of embedding medical data into medical images. However, most existed schemes of reversible dat...

Reversible Audio Data Hiding Based on Variable Error-Expansion of Linear Prediction for Segmental Audio and G.711 Speech

Reversible Data Hiding for JPEG Images Based on Histogram Pairs

This paper proposes a lossless data hiding technique for JPEG images based on histogram pairs. It embeds data into the JPEG quantized 8x8 block DCT coefficients and can achieve good performance in terms of PSNR versus payload through manipulating histogram pairs with optimum threshold and optimum region of the JPEG DCT coefficients. It can obtain higher payload than the prior arts. In addition,...
