Trusted services for risk management in work environments

In work environments, considered as pervasive environments with persons, materials, and tools which can be controlled via heterogeneous technological devices, several risks can be corrected and even prevented if properly managed. We propose an approach to address risks in work environments through trusted web services widespread on the various devices which monitor and control the safety status of the environment. We integrate the notion of risks in an environment with trust, such that one drives the other providing feedback for dynamic alerts based on the environment's constraints. A trusted cooperation protocol for services is outlined so that services can interact along wireless lines or service grids. We outline the technological features of a service system, which collects data from sensors and implements safety control technologies in work areas. © 2011 IEEE.
