STEGANALYSIS OF LSB INSERTION METHOD IN UNCOMMPRESSED IMAGES USING MATLAB

E N Ganesh

Abstract


In this paper we have explained steganalytic tool to detect presence of the hidden message in LSB steganography. It is the process of hiding secret information in cover image. Here we have used the LSB insertion method using discrete algorithms. Steganographic programs use Least Significant Bit (LSB) embedding as method of choice for message hiding 24-bit, 8-bit color images and grayscale images. It is commonly understood that changes to LSB of color cannot be detected due to the noise that is always presents in digital images. In this paper, we describe new very accurate and reliable method that can detect LSB. Embedding in the randomly scattered pixels in both 24-bit color images and 8- bit grayscale or color images.
