English abstract:
Complex Web-based information systems
involving multiple entities and their dynamic mobile-based
collaborations require efficient techniques for context information
sharing. Sharing control is a requirement for
preserving the privacy of personal context and shared
context. Our sharing control mechanism is hybrid, based
on sharing control rules defined by enterprise as well
as by individuals users. Our complex scenario involves
multiple entities which require prioritization and conflict
handling mechanism for entities and their policy rules.
This paper presents a sharing control model, Web servicesbased
architecture and its implementation with a running
example. The system is evaluated by comparing our hybrid
sharing control policy with enterprise-defined role -based
policy and shows effectiveness of our hybrid policy in
collaborative information sharing environments.

Context Sharing, collaborative system, hybrid sharing policy, access control, conflict handling.
