Secure Multi-mode Systems And Their Applications For Pervasive Computing

摘要

Pervasive computing environments present specific peculiarities with respect to aspects like security and multimodality. As a matter of fact, the accessibility level of a virtual environment can definitively be improved by natural interfaces and multimodal interaction systems, which offer users the freedom to select from multiple modes of interaction with services and permit to break down barriers about human-computer interaction making communication intuitive and spontaneous. On the other hand, while enlarging and easing the ways to access to the environment, security threads arise and the environment must be properly equipped in order to protect itself from malicious attacks and/or from wrong actions performed by inexpert users.
