Abstract

Steganografija je znanstvena disciplina koja proučava metode skrivanja informacija u naizgled bezazlene objekte (npr. slika, audio ili video zapis). Steganografskim postupcima osigurava se tajnost podataka u informacijskom sustavu jer osoba kojoj poruka nije namijenjena nije ni svjesna postojanja iste. Zbog toga je najviše zanimljiva za primjenu u vojne svrhe, odnosno u radu tajnih i obavještajnih službi, gdje je potreban visoki stupanj tajnosti. Rad daje uvid u steganografsku tehniku zamjene bitova najmanje važnosti te ispituje njenu učinkovitost.

Abstract (english)

Steganography is the scientific discipline that studies the methods of hiding informations in seemingly innocuous objects (eg, images, audio or video files). Steganographic procedures ensures the confidentiality of data in the information system because the person to whom the message is not intended is not even aware of its existence. Therefore, it is most interesting for use in military purposes, or in the work of secret and intelligence services, where a high level of secrecy is required. The paper provides insight into steganography technique of replacing bits of least importance, and examines its effectiveness.
