Abstract
Digitalni video zapis se snima i pohranjuje u digitalnom formatu kao jedinice i nule, za razliku od analognog koji koristi niz fotografija. Tehnološkim napretkom razvili su se razni standardi i formati video zapisa. Razvoj standarda kompresije video zapisa i tehnika koje su se koristile pri standardizaciji dolaze od dviju velikih međunarodnih organizacija ITU-T i MPEG. Video zapis je najkompleksniji oblik multimedije, a osim slike, zvuka, grafike i ostalih sadržaja, u sebi sadrži i meta podatke koji ga opisuju. Ti meta podaci mogu se na razne načine ekstrahirati iz video zapisa i na temelju njih možemo saznati mnoštvo informacija, od naziva datoteke, vremena snimanja, formata, do GPS oznaka gdje je video snimljen. Kako bi onemogućili zloupotrebu video zapisa, potrebno ga je zaštiti vodenim žigom. Na tržištu postoje razne aplikacije i alati pomoću kojih je moguće analizirati meta podatke. Forenzičkom analizom tih podataka, u mogućnosti smo spremati i obrađivati video zapise te mijenjati njihove meta podatke. Osim toga, moguće je koristiti video zapis kao kanal za tajnu komunikaciju na način da se neki oblik medija skrije u video zapis. Ovaj postupak naziva se steganografija, a koristi za prikrivanje digitalnog sadržaja kao što je tekst, slika, video ili audio zapis. Najvažnije je skriti informaciju na način da on ne izaziva sumnju.
Abstract (english)
Digital video is recorded and stored in digital format as ones and zeros, unlike analog video which uses a series of photos. Technological advances have developed various standards and video formats. The development of video compression standards and the techniques used in standardization come from two major international organizations, ITU-T and MPEG. Video is the most complex form of multimedia and in addition to image, sound, graphics and other content, it also contains metadata that describes it. This metadata can be extracted from videos in a variety of ways and can be used to learn a lot of information, from file name, recording time, format, to GPS tags where the video was recorded. In order to prevent the misuse of the video, it is necessary to protect it with a watermark. There are various applications and tools on the market that can be used to analyze metadata. By forensic analysis of this data, we are able to store and process videos and change their metadata. In addition, it is possible to use video as a channel for secret communication by hiding some form of media in the video. This procedure is called steganography, and is used to disguise digital content such as text, images, video, or audio. The most important thing is to hide the information in such a way that it does not cause suspicion.
