SSB7: A New Image Steganography System for Enhancement of Message Insertion Chance using 7th Bit of Pixel Value
Rajkumar Yadav, Ravi Prakash Saini, Gaurav Chawla · International Journal of Computer Applications · 2011
In this paper, a new Image Steganography method based on the spatial Domain is proposed.It does not use the known LSB's bit to embed the message.It uses the bit 7 of pixel value of cover image.The main idea is to make the bit 7 of pixel value equal to the message bit by adding or subtracting 1 to the pixel value.Our method is imperceptible to HVS because it provides minimum degradation in image quality due to only +1 or -1 change at a pixel value.Our method also provides 99.21% chances of message insertion at a pixel value which is near about optimal solution.We have compared our method with other methods in spatial domain by using various image steganography parameters.
