Abstract

Bose Chaudhuri Hochquenghem (BCH) based data hiding scheme for JPEG steganography is presented. Traditional data hiding approaches hide data into each block, where all the blocks are not overlapping each other. Two consecutive blocks can be overlapped to form a combined block which is larger than a single block, but smaller than two consecutive non overlapping blocks in size. In order to embed more amounts of data into the combined block than a single block. A way to get a joint solution for hiding data into two blocks with intersected coefficients such that any modification of the intersected area does not affect the data hiding process into both blocks. Due to hiding more amounts of data into the intersected area, embedding capacity is increased. The nonzero DCT coefficient stream is modified to achieve better steganalysis and to reduce the distortion impact after data hiding. Reducing distortion between the cover object and stego object is an important issue for steganography.
