Abstract

V diplomskem delu predstavimo različne steganografske tehnike, ki se uporabljajo v slikah JPEG. Za boljše razumevanje tematike najprej opišemo standard JPEG in se podrobno seznanimo z različnimi koraki. Zatem se osredotočimo na steganografske tehnike LSB, JSTEG, F3, F4, F5 in F5 z matričnim kodiranjem, primerne za slike JPEG. Opisane tehnike smo uporabili pri implementaciji steganografskega programa za slike JPEG. Implementirane steganografske tehnike smo nato med seboj primerjamo glede na njihovo učinkovitost.

Secondary title: STEGANOGRAPHY IN RASTER IMAGES JPEG
Secondary abstract: The thesis presents various steganographic techniques used in JPEG images. First of all the JPEG standard was described, together with a detailed tutorial on various steps in order to achieve a better understanding of the issue. After that we focused on the steganographic techniques LSB, JSTEG, F3, F4, F5, and F5 with matrix encoding suitable for JPEG images. The described techniques were used in the implementation of the steganographic program for JPEG images. Implemented steganographic techniques were then compared according to their effectiveness.
