Abstract
Internetske tehnologije značajno su povećale količinu i dostupnost informacija. Nastali su novi izazovi u zaštiti podataka i osjetljivih informacija. U ovome radu predstavljene su različite metode steganografije za skrivanje poruka unutar digitalnih slika, kao i metoda steganalize kojom je moguće otkriti samu postojanost poruka. Implementirane su dvije metode steganografije i metoda steganalize unutar Python okruženja, gdje prva metoda radi na principu spremanja podataka u najmanje značajne bitove piksela slike, dok druga metoda steganografije radi na istom principu, ali uz dodatna ograničenja radi smanjenja mogućnosti otkrivanja postojanosti poruke unutar slike.
Abstract (english)
Internet technologies have significantly increased the amount and availability of information. New challenges have arisen in the protection of data and sensitive information. This paper presents different methods of steganography for hiding messages within digital images, as well as a steganalysis method that can detect the very presence of messages. Two methods of steganography and a method of steganalysis were implemented within the Python environment, where the first method works on the principle of saving the data at least significant bits of image pixels, while the second method of steganography works on the same principle, but with additional restrictions to reduce the possibility of detecting the persistence of a message within an image.
