The technique of reversible data hiding recovers the original image from a stego-image
without distortion after the hidden data are extracted. A natural image usually contains …

The stego image quality produced by the histogram-shifting based reversible data hiding
technique is high; however, it often suffers from lower embedding capacity compared to …

As the network bandwidth has grown rapidly, it has become common to share a large
number of still images via the Internet by means of batch transmission. Unfortunately, most …

This paper presents a novel dual watermarking mechanism for digital media that embeds a
recognizable pattern into the spatial domain and an invisible logo into the frequency …

This work presents a novel reversible data-hiding scheme that embeds secret data into a
transformed image and achieves lossless reconstruction of vector quantization (VQ) indices …

The growth of image processing tools and applications has made it easy for multi-media
content such as music, audio, and video to be manipulated or forged during transmission …

In this paper, a reversible data‐hiding scheme in encrypted, vector quantization (VQ)
encoded images is proposed. During image encryption, VQ‐encoded image, including …

In this paper we show that, contrary to the common belief found in some of the literature,
Tchebichef moments are more sensitive to image additive noise than Zernike moments. We …

In this paper, a reversible data hiding scheme for vector quantization (VQ)-compressed
images is proposed. The scheme introduces two methods to explore the high correlations …

In this paper, a simple reversible data hiding (RDH) scheme for embedding a great amount
of information in JPEG images is proposed. Non-zero JPEG quantized coefficients are …
