Text Steganography through Different Indian Languages: Hiding and Extraction Techniques for Secured Data Transfer

Steganography is the art and science of hiding information such that its presence cannot be detected. This differs from cryptography, the art of secret writing, which is intended to make a message indecipherable by an unintended receiver but does not hide the existence of the secret communication. In steganography, the secret message is encoded in such a way that information’s existence kept hidden from the unintended receivers. In this monogram, a new system for text steganography through Indian Languages has been proposed for secured data communication through network. The system is a collection of the implementation of some existing methods like Word shifting, Line shifting, adding open spaces and synonym replacement methods on Indian Languages and some new algorithms like deterministic and non-deterministic Feature Coding methods using Indian Scripts, Linguistic Algorithms without using probabilistic approach, Dynamic Programming Method and Greedy Approach using property of sentences for data transfer. The proposed system ensures a satisfactory data hiding capacity with high security in terms of the steganography concepts.
