Abstract

In today’s world internet has emerged as an information hub which besides facilitating data sharing has logically connected people across the globe via chat, email, video conferencing etc. This ease of communication, however, is linked with serious security concerns of confidentiality, integrity, and non-repudiation that need to be addressed for secure communication. Steganography, one of the subdivisions of information hiding field, is now preferably been used in conjunction with cryptography to provide a doubly layered security shield to cater for the aforementioned confidentiality concern. This paper elaborates on a novel algorithm evolved for hiding sensitive information, twice in capacity as compared to its counterparts, inside ASCII text document/file. Also, conversion of stego objects to portable document format (.pdf) or when saved as MS Word (.doc), and converse, does not result in loss of hidden information or perceptibility.
