The World Congress on Internet Security (WorldCIS-2011) is Technically Co-Sponsored by IEEE UK/RI Computer Chapter. The WorldCIS-2011 is an international forum dedicated to the advancement of the theory and practical implementation of security on the Internet and Computer Networks. The inability to properly secure the Internet, computer networks, protecting the Internet against emerging threats and vulnerabilities, and sustaining privacy and trust has been a key focus of research. The WorldCIS aims to provide a highly professional and comparative academic research forum that promotes collaborative excellence between academia and industry.

On the ubiquitous networking environments, information is explosively used for various kinds of purposes. From a service perspective, a number of context or ambient aware services are envisaged for "ubiquitous networking" but based on the context security remains an issue.

The objectives of the WorldCIS are to bridge the knowledge gap between academia and industry, promote research esteem and and to fostering discussions on information technologies, information systems and globa security applications. The WorldCIS-2011 invites speakers and researchers to submit papers that encompass conceptual analysis, design implementation and performance evaluation.
