	abstract = {Cloud computing allows to move computing and storage components from individual systems into the cloud, which provides software and hardware services over the Internet. A collaborative application is among software services that can be provided by the cloud computing to enable collaboration among users from the same or different tenants. During such collaborations, the participants need to access and use resources held by other collaborating users. These resources often contain sensitive data. They are meant to be shared only during specific collaborative sessions. This paper proposes a Collaborative Task Role-Based Access Control CTRBAC1 model to ensures access control to the shared resources in a collaborative session in multi-tenants environments. The suggested C-TRBAC model is an extended version of RBAC in which new entities were added in order to support together: Collaboration in multi-tenant environment, active and passive access control and collaborative sessions. The suggested model has been implemented using Swift component in the open source cloud-computing platform {\textquoteleft}{\textquoteleft}OpenStack{{\textquoteright}{\textquoteright}}.},

A collaborative application is among software services that can be provided by the cloud computing to enable collaboration among users from the same or different tenants. In this context, security of the shared resources in a collaborative session becomes an important issue that must be addressed. This paper proposes an approach that ensures access control to the shared resources in a collaborative session in single tenant environments. The suggested approach introduces new entities and relationships to support collaborative sessions in single-tenant environments. Finally, we validate this approach by an implementation in the SwiftStack environment.},
