Protecting Intellectual Property in Collaborative Design

Project status: Complete

Thrust area: Enabling Information Infrastructure

Research team: Jose Brustolini,

This project developed Web protocol, server, and browser modifications that enable secure posting and retrieval of documents with usage controls. In our approach, no modifications are necessary in applications used for authoring and displaying usage-controlled files. The hardware-based controls thwart attacks against software-based DRM by ensuring that only trusted applications can open usage-controlled documents. This protection adds little overhead, and user studies in the lab suggest that the system is easy to use even by untrained users.
