AN EFFICIENT ALGORITHMIC SOLUTION FOR HIGH PAYLOAD GOOD IMPERCEPTIBILITY HYBRID IMAGE STEGANOGRAPHY


 A hybrid steganographic technique has been proposed to enlarge the size of secret message and hide several images in one cover image. Initially, were compressed using JPEG 2000 before embedding them Second least significant bit plane image was entirely replaced by while tri-ways-pixel-value-differencing (TPVD) used remaining seven-bit The quality stego enhanced residual coding (RIC). divided four sub-images, three provided for fourth sub-image embed RIC only TPVD, ensure better terms peak signal noise ratio (PSNR). Proposed opportunity transmit data without detection different steganalysis techniques like dual statistics steganalysis. Experimental results verified that achieved high payload with than TPVD scheme.
