magistrsko delo

Abstract

V magistrskem delu predstavimo atraktivno področje računalništva, steganografijo, ki se ukvarja z neopaznim skrivanjem podatkov. Prikrita komunikacija oziroma neopazno pošiljanje sporočil je zelo pomemben dejavnik v današnji družbi, kjer nas na vsakem koraku obkrožajo različne novice in informacije. Tako kot lahko informacije sporočamo na različne načine, tako lahko tudi podatke skrivamo v različne medije, ki se uporabljajo za komuniciranje. V tej magistrski nalogi predstavimo steganografski algoritem za skrivanje podatkov v videoposnetkih s pomočjo Haarove transformacije in algoritma F5. Z rezultati pokažemo učinkovitost predstavljenega postopka za skrivanja podatkov v videoposnetkih z namensko dodanim šumom.

Secondary title:	Steganography-Based data hiding in video using Haar space
Secondary abstract:	In this thesis we describe very attractive area of computer science: steganography, which deals with the invisible concealment of data. Covert communication or unnoticed sending of messages is a very important factor in today's society, where we are surrounded by various types of news and information at every step. Just as we can communicate in different ways, we can also hide data in different media types used for communication. In this thesis, we present a steganographic algorithm for hiding data in videos using the Haar transformation and the F5 algorithm. The results show the effectiveness of the presented procedure for hiding data in videos with intentionally added noise.
