A real time text steganalysis by using statistical method

Steganography is the art of hiding data in data in an untraceable way. Main concern of steganography is hiding the existence of hidden message. Steganalysis is the art and science of detecting hidden messages from stego-systems. It also attempts to find hidden message such as the type of embedding algorithm, the length of the message, the content of the message or the secret key used from the carrier (like image, text, video etc.). In this paper, we have discussed the steganalysis technique by using Bayesian Estimation and Correlation Coefficient based steganalysis methodologies for text.
