Digital Collaborations are proving themselves as ideal environments for increasing the productivity and knowledge exploration capabilities of their members. Many organizations are realizing the diverse range of benefits they provide to not only their organization as a whole but also to individual employees. The challenge in environments that encourage the sharing of resources in particular data, is finding a sustainable halance between the need to provide access to data while also insuring its security in addition to the privacy of the entities it may pertain to. In this paper we propose an authentication framework that uniquely combines both traditional and biometric methods of authentication with an additional novel audiovisual method of authentication. The CASE (Combined Authentication Scheme Encapsulation) methodology, the name of our solution, provides an effective visual representation of both the authentication and information privacy hierarchies associated with data requests within digital collaborative environments.
