Rubik's Cube: A Way for Random Image Steganography

Yet another but an incremental reversible data hiding- for an irreversible data safety

“…STEP [1] Divide the cover image in to small blocks STEP [2] Construct the difference image STEP [3] Find the peak point using histogram STEP [4] Modify the image using modification principle STEP [5] Embed the data in the modified image STEP [6] Marked image is constructed using inverse transformation B. Message extraction and reconstruction STEP [1] Divide the marked image in to blocks STEP [2] Calculate the difference image STEP [3] Extract the message and remove the embedded bits from the marked pixels STEP [4] Shift the pixel values to reconstruct the original difference image STEP [5] By applying inverse transformation, original image has been obtained C. Inverse S order STEP [1] Cover image is scanned using inverse S order fashion STEP [2] Pixel differences between the adjacent pixels are calculated.…”

“…STEP [3] Get the Embedding level as input(EL) STEP [4] Hiding the secret can be done based on the values of EL (EL=0 or EL >0) STEP [5] Data hiding can be carried over EL +1 times E. Message extraction and reconstruction STEP [1] Scan the marked image using inverse S order STEP [2] Obtain the value of EL STEP [3] Check if EL=0 or EL >0 STEP [4] Based on EL extraction can be done to reconstruct the original image.…”

“…An ancient art of information hiding is the Steganography which always aims at hiding the presence of secrecy in any communication channel [1][2][3][4][5][6][7]. The intruder will be completely aware of the message present.…”

Chaotic & partial encrypted image on XOR bus - an unidentified carrier approach

“…In this modern world, digital communication has wide range of applications for information security which could be classified as Steganography [5][6][7][8][9][10][11][12][13][14][15][16][17], Watermarking [2,6], Spread Spectrum [18][19][20][21][22] and Encryption [23][24][25][26][27][28][29][30][31][32][33][34][35].…”
