A Lossless Data Hiding Scheme Using Reference Pixel and Multi-layer Embedding
نویسنده
چکیده
This paper proposes a lossless data hiding method which is based on the pixel difference histogram shifting to spare space for data hiding in spatial domain. Pixel differences are generated between a reference pixel and its neighbors in a pre-assigned block. After the difference histogram shifting, a large number of data can be embedded into the cover image, and multi-layer embedding is used to improve the hiding capacity. Different from our previous researches based on histogram shifting, the proposed scheme can extract the hidden data and recover the exact original cover image with no extra information except the length of hidden data and the watermarked image itself. The proposed scheme can offer very high embedding capacity and low image degradation, and the exact original cover image can be fully restored after the hidden data are extracted with no error. The Simulation results demonstrate high degree of performance for the proposed method.

Lossless Data Hiding Scheme Using Adjacent Pixel Difference Based on Scan Path
This paper presents a reversible data hiding scheme. The proposed scheme is based on the difference histogram shifting to spare space for data hiding. Nine basic scan paths are defined, and this means all-directional adjacent pixel differences can be obtained. Due to the fact that the grayscale values of adjacent pixels are close to each other, the all-directional adjacent pixel difference hist...

This letter presents a lossless data hiding scheme for digital images which uses an edge detector to locate plain areas for embedding. The proposed method takes advantage of the well-known gradient adjacent prediction utilized in image coding. In the suggested scheme, prediction errors and edge values are first computed and then, excluding the edge pixels, prediction error values are slightly m...
