Invisible Communication through Portable Document File (PDF) Format
Gundeep Singh Bindra · 2011
With the fast paced development of the internet, exchanging or concealing of private data has become a serious concern. This Paper proposes a new and an unidentified steganographic technique to conceal your data which can be further encrypted (through cryptography) in a .pdf file format. The informative-theoretic method for performing steganography deals with text-to-text steganography while restoring the carrier file along with the hidden message after binding it in a PDF file format. This paper introduces a new steganographic technique through a PDF medium. It also suggests plausibility of exploring the possibility of adding layers of security to the suggested information hiding technique.
