Improved Lossless Embedding and Extraction - A Data Hiding Mechanism
This paper proposes a reversible data hiding mechanism based on multiresolution analysis with difference expansion algorithm. Based on the multiresolution analysis of an image, gradient information of crude original image is exploited to select proper embedding areas. Adaptively embedding method based on Difference Expansion Algorithm is proposed to embed data into the host image without causin...
متن کاملReversibility improved lossless data hiding
Recently, lossless data hiding has attracted increasing interests. As a reversible watermark scheme, the host media and hidden data should be recovered without distortion. A latest lossless data hiding technique based on image blocking and block classification has achieved good performance for image authentication. However, this method cannot always fully restore all the blocks of host images a...
متن کاملRobust Lossless Data Hiding by Feature-Based Bit Embedding Algorithm
Recently, data hiding, or information hiding, plays an important role in data assurance. Generally speaking, data hiding techniques can be classified into steganography and digital watermarking (Cox et al., 2008; Shih, 2008). The marked images generated by the steganographic methods (Gu & Gao, 2009; Liu & Shih, 2008; Qu et al., 2010; Wang et al., 2010; Zhou et al., 2010; Fan et al., 2011) were ...
متن کاملA Lossless Data Hiding Scheme Using Reference Pixel and Multi-layer Embedding
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...
متن کاملA lossless robust data hiding scheme
This paper presents a lossless robust data hiding scheme. The original cover image can be recovered without any distortion after the hidden data have been extracted if the stego-image remains intact, and on the other hand, the hidden data can still be extracted correctly if the stego-image goes through JPEG compression to some extent. The proposed scheme divides a cover image into a number of n...
