Abstract:
V diplomskem delu najprej predstavimo pomembne aspekte slikovnega formata PNG, kjer razložimo koncept prepletanja in filtre PNG. Nato se osredotočimo na metode za prekrivanje informacije. Osredotočimo se na metode LSB, LSBMR, PVD, PPV in EMD. Metode implementiramo in jih nato med seboj primerjamo.
