Most research works in ubiquitous computing remain in the domain of mono-user systems, which make assumptions such as: "nobody interferes, observes and hurries up". In addition, these systems ignore third-part contributions and do not encourage consensus achievement. This paper proposes a system for managing availability of distributed resources in ubiquitous cooperative environments. Particularly, the proposed system allows collaborators to publish resources that are intended to be shared with others collaborators and to subscribe to allowed resources depending on their interest in accessing or using them. Resource availability is determined according to several parameters: technical characteristics, roles, usage restrictions, and dependencies with other resources in terms of ownership, presence, location, and even availability. To permit or deny access to context-aware information, we develop a face recognition system, which is able to dynamically identify collaborators and to automatically locate them within the cooperative environment.
