Sistematični pregledi literature so bistvenega pomena tako za pregled raziskanosti določene teme kot tudi za potek nadaljnih raziskav na akademskih prodročjih. Predstavljajo natančen pregled že objavljenega gradiva na določeno temo. Pri opravljanju pregleda si večina pomaga z uporabo različnih metod, ki pomagajo pri doslednjem načrtovanju in ohranjajo integriteto pri samem izvajanju pregleda. Zato smo v tem diplomskem delu preverjali dejansko stanje uporabe metod, njihovo delovanje in popularnost, saj je objavljenih raziskav na to temo zelo malo. Dodatno smo pregledovali tudi steganografske metode, ki se uporabljajo v multimediji, saj na tem področju še ni bilo opravljenih nobenih raziskav. Zaradi vsakdanje uporabe vseh vrst medijev smo pregledovali, katere metode so najbolj v uporabi in tudi s katerimi metodami se raziskovalci največ ukvarjajo. Da bi preverili stanje, smo opravili dve študiji v bibliografskima bazama Web of Science in Scopus. V prvi študiji smo preverili stanje metod za sistematični pregled literature, pri kateri smo preverili 61 virov, od katerih je bilo 23 skladnih s postavljenimi kriteriji. Od teh jih je osem izpostavilo metodo pregleda literature. V drugi študiji smo preverili steganografske metode v skupnih 209 virih, od katerih je kriterijem ustrezalo 46 virov, ki so bili vključeni v študijo. Rezultati prve študije so nam prikazali, da se večina raziskovalcev poslužuje metode PRISMA. To so po našem mnenju pričakovani rezultati, saj je ta metoda ena izmed najbolj razširjenih in ima poleg glavnega načrta dela še dodatne razširitve za ostale vrste pregledov literature. Zanimivi so podatki, da velik del pregledanih virov ne navaja uporabljene metode, torej lahko sklepamo, da veliko raziskovalcev ne uporablja metod pri opravljanju pregledov literature. Rezultati druge študije, kjer smo pregledovali steganografske metode v multimediji, prikažejo kot najbolj uporabljeno metodo LSB (angl. least significant bit). Druge najpogosotejše metode si po številu virov sledijo: discrete cosine transform, lastne metode oz. tiste, ki so jih avtorji sami predlagali, discrete wavelet transform, OutGuess, F5, JSteg, chi-square in Stegosploit. Ostale metode so bile omenjene le v posameznih primerih. Poleg tega pa smo opazili, da je od vseh različnih medijev najbolj raziskan slikovni oziroma fotografski, najmanj pa besedilni medij.

Sekundarni naslov:	Analysis of systematic literature reviews in the steganography research area
Sekundarni povzetek:	Systematic literature reviews are essential both to review already existing research and to conduct further research in academic fields. They present a detailed review of material already published on a particular topic or field. Most reviewers use a variety of methods to help ensure consistent planning and integrity in the conduct of the review itself. Therefore, in this thesis we have examined the actual state of methods used in systematic literature reviews, their performance and popularity, as there is very little research published on this topic. Additionally, we also reviewed steganographic methods used in multimedia, as to our knowledge, no research has been done in this area. Due to constant use of different media types we looked at which methods are used the most and also which methods are most often used by researchers. In order to research this, two studies were carried out in bibliographic databases Web of Science and Scopus. In the first study, we checked the status of methods for systematic literature review, where we reviewed 61 sources, 23 of which met the set criteria. Of these, further eight were flagged for including a literature review method. In the second study, we checked steganographic methods in a total of 209 sources, of which 46 sources met the criteria included in the study. The results of the first study showed that most researchers use the PRISMA method. This is, in our opinion, an expected result as the method is one of the most widely used and has additional extensions for other types of literature reviews in addition to the main work plan. It is also interesting to note that a large proportion of the sources reviewed do not indicate which method was used, suggesting that many researchers do not use methods when conducting literature reviews. The results of the second study, where we reviewed steganographic methods in multimedia, show the LSB (least significant bit) as the most used method. The other commonly used methods in terms of number of sources are as follows: DCT (discrete cosine transform), own methods or those proposed by the authors themselves, DWT (discrete wavelet transform), OutGuess, F5, Jsteg, chi-square and Stegosploit. Other methods were mentioned only in a low number of cases. In addition, we noticed that of all different media types, the most researched is the image or photographic medium, and the least researched is the textual medium.
