I have been employed in the Information and Communication Technology - ICT - industry since 1982, involved in a wide range of projects, until I commenced formal study at 2001.

I have focused my research interest on the art and science of hiding information and its implementation in the real world. I have been working on this from an historical perspective, from ancient ages to the present, and considering a wide range of disciplines, techniques and technologies.
