摘要：Steganography it is a form of security through obscurity. It is the art and science of writing hidden messages in such a way that no one, except sender and intended recipient can understand the hidden message,. The purpose of steganography is covert communication-to hide the existence of a message from a third party. Compared with study on text-steganography, research on text-steganalysis is in its infancy. In this paper, we present a method that is capable of performing text Steganography that is more reliable and secure when compared to the existing algorithms. Our method is a combination of Word shifting, Text Steganography and Synonym Text Steganography. So we called this as "Three Phase Shielding Text Steganography" This method overcomes various limitations faced by the existing Steganographic algorithms. The experimental results are very encouraging when compared to the already existing algorithms. Our method also helps in finding out the embedding rate of a secret message in a text document.
