Zastosowanie steganografii w sieciach komputerowych

Abstract

The widespread availability of the Internet requires protection of data transmitted and stored in ICT systems. Their confidentiality is provided by encryption, while to watermark the original electronic files or hide the fact that the transmission of contents occurs (e.g. in relation to economic, political or criminal activity) steganographic techniques are used. The development of network steganography allows for more effective information hiding, so it is necessary to improve steganalitics related to identifying and analyzing steganograms. The aim of the article is to present issues concerning steganographic methods which, combined with cryptographic mechanisms, are an effective tool for protecting information against detection and readout.
