Abstract:Diplomska naloga obravnava skrivno komuniciranje z uporabo informacijskih tehnologij. Kadar zgolj zaščita podatkov pred branjem ne zadostuje in želimo prikriti obstoj določenih informacij, se lahko za komuniciranje poslužimo steganografskih orodij, ki omogočajo skrivanje sporočil v različne digitalne medije. V teoretičnem delu diplomske naloge je podrobneje predstavljen pojem steganografija, njena zgodovina, princip delovanja steganografskih orodij, načini za varno komuniciranje ter različne steganografske metode. Predstavljene so tudi metode stegoanalize in stegoanalitska orodja. V praktičnem delu je bilo testiranih pet steganografskih orodij s petimi različnimi metodami za zaznavo skrivnih sporočil. Z uporabo stegoanalitskih orodij sem ugotavljal, kako učinkovito so steganografska orodja skrila skrivna sporočila. Na koncu sem določil uporabnost orodij glede na različne kriterije. Rezultati učinkovitosti so pokazali, da so steganografska orodja primerna predvsem za domačo uporabo, za integracijo v podjetja pa bi bilo potrebno uvesti nekaj sprememb.

Title:ANALYSIS OF STEGANOGRAPHY TOOLS FOR EMBEDDING IN PICTURES
Abstract:The diploma discusses exchange of secret data by using different information technologies. When merely protection of data from being exposed is not sufficient, steganography tools for hiding messages into different digital media can be used. Theoretical part of the diploma focuses on explaining the term steganography, presenting the ways of safe communication and showing different steganographic methods. There is also a presentation of steganalysis and steganalysis tools. In practical part of the diploma, we chose five steganography tools and tested them using five different steganalysis methods. The goal was to estimate the effectivness of steganography tools and to deterimine how well steganography tools have hidden secret messages. Based on the results, we can conclude that the chosen steganography tools are useful and effective enough for a non-professional use, but some improvements should be made if we wanted to integrate them into professional use in companies.
