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