PROJECT DESCRIPTION What Is Steganography? Steganography applications conceal information in other‚ seemingly innocent media. Steganographic results may masquerade as other file for data types‚ be concealed within various media‚ or even hidden in network traffic or disk space. We are only limited by our imagination in the many ways information and data can be exploited to conceal additional information. For many years Information Hiding has captured the imagination of researchers. Digital watermarking
