Abstract
Želimo li zaštititi multimedijske dokumente potreban nam je način upisivanja dodatnih informacija u dokument. Steganografija je područje koje upisuje podatke u medije, slike, videozapise, audiozapise bez da unosi čovjeku razlučive promjene. Uvodimo dva steganografska algoritma. Algoritam LSB koji podatke unosi u najniže bitove piksela slike i BPCS koji prvo pronalazi kompleksna područja slike u koja onda upisuje podatke. Implementirali smo oba algoritma u programskom jeziku C++ i rezultate unosa podataka usporedili s javno dostupnim implementacijama.
Abstract (english)
If we want to protect multimedia documents, we need a way to write additional information into the document. Steganography is a field that records data in media, images, videos, audio recordings without introducing human-detectable changes. We introduce two steganographic algorithms. LSB which enters data into the lowest bits of image pixels and BPCS which first finds complex areas of the image and then writes data into them. We implemented both algorithms in the programming language C++ and compared the data results with publicly available implementations.
