Abstract

U završnom radu analiziraju se metode steganografske obrade podataka. Izlaganje teme započinje povijesnim pregledom steganografskih tehnika obrade podataka. Objašnjavaju se razlike između steganografije i kriptografije, a zatim se obrađuju osnovni pojmovi koji čine steganografski sustav. Na primjeru „problema zatvorenika“ detaljno se opisuje princip rada steganografije. Na to se nastavljaju steganografske tehnike koje su razdijeljene i objašnjene te se opisuju načini skrivanja poruke u digitalni nositelj. Zatim se dolazi do glavnog dijela rada u kojem se opisuju steganografske metode s obzirom na medij kojim se stego poruka prenosi. U završnom dijelu rada opisuje se stegoanaliza te se programskim alatima StegSpyi Digital InvisibleInkToolkit na konkretnim primjerima prikazuje kodiranje, dekodiranje i stegoanaliza tajne poruke.

Abstract (english)

The final paper analyzes the methods of steganographic data processing. Topic presentation begins with historical overview of steganographic techniques of data processing.The differences between steganography and cryptography are explained, and basic concepts that make steganographic system are then discussed. Using the example of “inmates problem” the working principle of steganography is described in detail. Steganographic techniques build on it, those that are separated and explained, and describe ways of hiding messages into digital carriers. That leads to the main part of the paper which describes steganographic methods based on the medium through which stego-message is transmitted. In the final part of the paper stego-analysis is described and programming tools, StegSpy and Digital InvisibleInkToolkit, show concrete examples of encoding, decoding and analysis of stego-secret messages.
