1. Framework for Managing the Assured Information Sharing Lifecycle UMBC, Purdue, UT Dallas, UIUC, UT San Antonio, Michigan AFOSR MURI FA9550-08-1-0265, June 2008 start Information value chain • Objectives • Create a new framework for assured information sharing (AIS) that recognizes that sharable information has a lifecycle of production, release, advertising, discovery, acquisition, and use • Develop techniques grounded in this model to promote information sharing while maintaining appropriate security, privacy and accountability • Evaluate, adapt and improve the AIS concepts and algorithms in relevant test beds information has a lifecycle involving a web of producers and consumers All aspects of the lifecycle are shaped by distributed information sharing policies Integration and mining creates new information that may be shared access may involve negotiating policy defined obligations • Approach • Design a service oriented architecture to support the assured information sharing lifecycle • Create new policy models & languages to express and enforce AIS rules & constraints • Develop new data mining techniques and algorithms to track provenance, increase quality and preserve privacy • Model underlying organizational social networks to estimate trust and information novelty • Design incentive structures to motivate sharing in organizations and coalitions • Accomplishments • EXAM system for XACML policy analysis & visualization • New model for secure sharing of information in search • An evolutionary game theoretic simulation framework modeling distributed trust for AIS incentives • Published over 20 papers, organized conferences and workshops, see http://aisl.umbc.edu/ for details • Potential impact • Lowering information sharing barriers while maintaining security & privacy constraints increases efficiency and reduces missed opportunities • Improved policy models will make information sharing policies easier to author and understand 1/20/2009
