Existing cloud storage systems lack privacy aware architectures that meet accessibility goals for complex collaboration. This deficiency is fully realized in the healthcare industry, where cloud-enabling technology blurs the ownership boundary of health and wellness information. Whether among traditional `stovepiped' data silos, health information exchanges(More)
In this paper, we propose a flexible framework to accomplish workflow modeling from network traffic, the Access Profile Statistical Analysis Tool (APSAT). In APSAT, workflow modeling is decomposed into four layers: packet flows, Resource Access Actions (RAA), workflow periods, and workflow behavior. We develop a novel approach to compress packet flows into(More)
In the pursuit of behavior modeling for dynamic policy management and usage control, mission centric systems are the most important to examine, not only because situation dynamics can dramatically alter the collaboration environment, but also since behavior in these systems is constrained by mission objectives or workflows. Traditional mission decomposition(More)
Vision is vital to decision making, as humans naturally trust their eyes to enhance situation awareness. Yet the modern age has overwhelmed humans with massive amounts of visual information, which is problematic in time sensitive and mission critical situations, such as emergency management and disaster response. More efficient search and retrieval systems(More)
