Convergence security systems

Convergence-based service environments are embedded in large-capacity servers and adopt client/server models. Applications, devices, networks, and infrastructure are converging and creating an immense amount of content, which poses complex challenges for organizations, developers and users. In the field of security, we are seeing the convergence of frameworks and paradigms like augmented reality, ubiquitous computing and pervasive computing; and we are seeing new kinds of content, much of it user-generated, that can be searched, organized and consumed on many devices and in many formats [10–15]. The challenges of converged security, hacking, computer virology technologies and content require new algorithms, application paradigms, interaction methods, and services; the creation of expressive annota-
