Agile information sharing

One of the oldest and most challenging problems in cyber security is to enable secure information sharing (SIS) (i.e., maintaining some control over information even after it has been shared.) For example, a product manufacturer may need to share customer account information with a company that ships the products and bills the customers. The manufacturer cannot allow its partner to then misuse those customer records by direct marketing or selling customer records. This project focuses on the policy challenge of specifying, analyzing and enforcing SIS policies.
