  In this paper, a novel steganographic scheme based on chaotic iterations is
proposed. This research work takes place into the information hiding framework,
and focus more specifically on robust steganography. Steganographic algorithms
can participate in the development of a semantic web: medias being on the
Internet can be enriched by information related to their contents, authors,
etc., leading to better results for the search engines that can deal with such
tags. As media can be modified by users for various reasons, it is preferable
that these embedding tags can resist to changes resulting from some classical
transformations as for example cropping, rotation, image conversion, and so on.
This is why a new robust watermarking scheme for semantic search engines is
proposed in this document. For the sake of completeness, the robustness of this
scheme is finally compared to existing established algorithms.
