Abstract
Digital information is one of the sensitive resources in any organization that needs to be well protected and secured to avoid unauthorized access and consequently its misuse. In a group centric environment dynamic sharing of resources takes place within an authorized group of users for a specific purpose. Security of shared resources becomes more important and challenging in a group-centric environment. Different organizations comprise of a complex structure in which multiple groups exist at a time and access rights are provisioned and delegated within groups. Groups are created and disassembled dynamically based on events or tasks required. These complex structures need to be managed and secured and we need effective provisioning of access control and delegation of access rights within these groups. We present a comparative study of the access control models in group-centric environment and discuss the open research areas in group centric environment.
