A Symmetric Key Based Steganography Algorithm for Secured Data Transfer

Steganography is the art of hiding information efficiently into another media. It serves as a better way of securing message than cryptography which only conceals the content of the information. Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. So the hidden message is difficult to detect without retrieval. In the recent years, the authors have plenty of security tools which are developed to protect the transmission of multimedia objects. But approaches for the security of text messages are comparatively less. In this paper, a new steganographic approach is proposed which imposes the concept of secrecy over privacy for text messages.
