Digital Image Steganography using Nine-Pixel Differencing and Modified LSB Substitution
To provide higher embedding capacity without sacrificing the imperceptibility, a novel steganographic technique based on nine-pixel differencing with modified Least Significant Bit (LSB) substitution is proposed. The image is divided into 3×3 non-overlapping blocks. In each block the average difference value is calculated. Based on this value the block is classified to fall into one of the four...
متن کاملSteganography on Digital Image Using Pixel Values Differencing (pvd) Method
Internet as a communication media brings easiness, speed, and lower costs, but this media couldn’t give any safety guarantee. That’s why the data should be protected from unauthorized people. Steganograhpy technique could be used to do the protection. This technique inserts data or information into object cover, which is digital image. The succes criteria of steganography implementation is when...
متن کاملA steganographic method for digital images with four-pixel differencing and modified LSB substitution
To improve the embedding capacity and provide an imperceptible visual quality, a novel steganographic method based on four-pixel differencing and modified least significant bit (LSB) substitution is presented. The average difference value of a four-pixel block is exploited to classify the block as a smooth area or an edge area. Secret data are hidden into each pixel by the k-bit modified LSB su...

متن کاملSteganalysis Method Defeating the Modified Pixel-value Differencing Steganography
Pixel-value differencing (PVD) steganography generates step effects or abnormal high fluctuations in PVD histogram. Since steganalysis exploits these artifacts to defeat the PVD steganography, modified PVD (MPVD) steganography preserving the PVD histogram is recently presented. This paper proposes a novel steganalysis method, in which we embed message one more time into the suspicious image to ...
