Content dependent secret hiding in visual steganography

Abstract

In this paper we'll describe new techniques of information hiding in visual containers. Presented methods will be connected with the carrier features, so secret distribution will be dependent from the content and pixel values. In traditional secret hiding solutions the way of information distribution is not dependent on the content or container's features. Such approaches simply modify spatial or frequency parameters, without consideration of local carrier parameters. Such parameters can also determine the way of secret hiding and allow to split information over container in different manner, especially when we consider containers with different graphical features.
