Abstract

Steganografija je znanstvena disciplina koja proučava tajnu komunikaciju putem medija bezazlenog sadržaja, npr. slika, audio ili video zapis. Temelji se na pretpostavci da vidljivost ugrađenih podataka predstavlja ranjivost sustava, dakle cilj je prikrivanje samog postojanja ugrađenih tajnih podatka. Rad daje uvid u povijest steganografije, osnovne steganografske metode, razvoj metode za označavanje slika kao i simulaciju napada u svrhu ispitivanja učinkovitosti algoritma kako bi se sačuvao integritet podataka.

Abstract in english:	Steganography is a scientific discipline that studies the secret communication through the harmless contents media, eg. image, audio or video. It is based on the assumption that the visibility of embedded data is the vulnerability of the system, so the aim is concealing the existence of an embedded secret information. The paper gives an insight into the history of steganography, basic steganography methods, and the development of the method for labeling images as well as simulation of attacks in order to test the effectiveness of the algorithm to preserve data integrity.
