A Security Model for Distributed Collaborative Environments in the Healthcare

Distributed Collaborative Environments provide a common user interface that enables collaborative tasks of geographically dispersed users in a specific context. In such environments, many features can be provided, such as asynchronous and synchronous communication mechanisms, a repository for shared resources, and concurrent (synchronous) edition of content. However, it is clear that there is still a shortage concerning the security support in such environments. This becomes even more severe when the context in which these environments are inserted deals with sensitive data, such as patient data and their medical records. The present work proposes a security model for distributed collaborative environments focusing the support for medical researches.
