Publish/subscribe systems provide an efficient, event-based, wide-area distributed communications infrastructure. Large scale publish/subscribe systems are likely to employ components of the event transport network owned by cooperating, but independent organisations. As the number of participants in the network increases, security becomes an increasing… (More)
Publish/subscribe research has so far been mostly focused on efficient event routing, event filtering, and composite event detection. The little research that has been published regarding security in publish/subscribe systems has been tentative at best. This paper presents a model for secure type names, and definitions for type-checked, content-based… (More)
Publish/subscribe has emerged as an attractive communication paradigm for building Internet-wide distributed systems by decoupling message senders from receivers. So far most of the research on publish/subscribe has focused on efficient event routing, event filtering, and composite event detection. Very little research has been published regarding securing… (More)
Content-based publish/subscribe provides a flexible communication model for component interoperation in large-scale environments. In process support systems and other applications that follow an event-based architectural style, the definition of dependencies between interacting components and the notion of all-or-nothing semantics are often needed to ensure… (More)

BACKGROUND As in many European countries, Finnish psychiatric services experienced a rapid process of deinstitutionalization in the 1990s. In recent decades, the decrease in numbers of psychiatric hospital beds has in several countries been found to be linked with increasing criminality among severely mentally ill individuals. It has been concluded that… (More)
