Reversible Data Hiding Based on Histogram Modification of Pixel Differences
TL;DR: A binary tree structure is exploited to solve the problem of communicating pairs of peak points and distribution of pixel differences is used to achieve large hiding capacity while keeping the distortion low.
Journal ArticleDOI
Multilevel reversible data hiding based on histogram modification of difference images
TL;DR: This paper proposes a multilevel reversible data hiding scheme based on the difference image histogram modification that uses the peak point to hide messages through a joint imperceptibility and hiding capacity evaluation.
Journal ArticleDOI
Reversible hiding in DCT-based compressed images
TL;DR: A lossless and reversible steganography scheme for hiding secret data in each block of quantized discrete cosine transformation (DCT) coefficients in JPEG images that can provide expected acceptable image quality of stego-images and successfully achieve reversibility.
Journal ArticleDOI
A Reversible Data Hiding Scheme Based on Side Match Vector Quantization
TL;DR: Experimental results show that the performance of the proposed reversible data hiding scheme based on side match vector quantization (SMVQ) for digitally compressed images is better than those of other information hiding schemes for VQ- based and SMVQ-based compressed images.
Journal ArticleDOI
Four-scanning attack on hierarchical digital watermarking method for image tamper detection and recovery
TL;DR: A four-scanning attack aimed to Lin et al.'s watermarking method is presented to create tampered images and in case they use encryption to protect their 3-tuple-watermark, a blind attack to tamper watermarked images without being detected is proposed.
