Abstract:
With the rapid growth of networking mechanisms, where large amount of data can be transferred between users over different media, the necessity of secure systems to maintain data privacy increases significantly. Different techniques have been introduced to encrypt data during the transfer process to avoid any kind of attack. One of these techniques is to hide the data inside another file which is called Steganography. In steganography, data is hidden inside a carrier file where anyone can see, but the hidden data inside it cannot be discovered. To this end, good algorithms can avoid the suspicion of having any attacker by applying some criteria before sending the data. In this paper, we present an algorithm to hide data using a text file as a carrier. Left-Right Remarks that represent Unicode symbols are used to hide the data inside the text file. Moreover, our algorithm can be applied in different size textual data.
