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
