A NOVEL APPROACH TO ENHANCE EMBEDDING CAPACITY IN SPATIAL DOMAIN FOR IMAGE STEGANOGRAPHY USING IRREGULAR DATASETS

Digital image steganography is a kind of technique for securing data from unauthorized and
unethical persons. A tug-of-war is continuous between the embedding capacity and distortion
caused in the image. A balance has to be maintained between the two so that neither does affect
the other. In this paper, I dealt with a new thought and carried the embedding capacity to a great
extent as much as three times the number of pixels in the image. I have used multi-keys for
embedding the message to strengthen the security and allowed the distortion to occur as much as
possible. Distorted image is treated as the new image and both these images are incorporated in the extraction process.Recipient is flooded with many such images during transmission to divert the attention of intruders. Experimental results show that it is very difficult to guess and extract the message and at the same time increasing the embedding capacity to horizon.
