Advanced Collage Steganography

Abstract

Establishing hidden communication is an important subject that nowadays has gained increasing importance. Embedding a secret message into a cover media without attracting any attention, known as steganography, is one of the methods used for hidden communication. In this paper, we present an advanced version of “Collage Steganography” method which is robust against various
attacks. In this method, an image (for example a view of a room) is created which contains some coded information. This method is robust against attacks such as adding noise, blurring, JPEG compression, and print-scan attacks.
