A new method for pdf steganography in justified texts

Recommended Posts

Pentru pasionati...

 

In this paper we introduce a hiding method which is based on justified text in a pdf file. In this proposed method, first we compress the secret message by Huffman coding. Then we choose some special lines of the cover as host lines. The embedding operation occurs by the replacement of the added spaces by the normal spaces of the host lines. Finally we re-pdf the file and send it.

 

This scheme has a key, and in each use we can choose a new key for increasing the security of the communications. In this proposed method we can embed more information in a cover-text compared with several other text steganography schemes. Also the size of the file of the cover is not changed in this method. The next advantage of this method is that the parties of secret communication do not need to send electronic files and furthermore this method is printable.
