  2. Contents • What is an Information Bearing Agent (IBA) ? • Position of IBA’s in a evolutionary perspective • Rational of IBA’s • Behaviors: • Information maintenance • Information security • Demonstration TNO Defense and Security, Ronald Poell

  3. What is an Information Bearing Agent (IBA) ? • IBA’s contain some information. • Similar to a row (or rows) in a table of a relational database or to a node from the Semantic Network • Their information is unique (no other IBA’s have the same information) • They are responsible for their information • IBA’s can be stored as an optionally encrypted file assuring persistency over time. • IBA’s have behaviors enabling manipulation of the information they are bearing. TNO Defense and Security, Ronald Poell

  4. Position of IBA’s in a evolutionary perspective • They represent the second phase in the evolution of the Semantic Network Technology (Poell, 2001) • The first stage is a Semantic Network (with the actual Semantic Network Engine). • The second level consist of the usage of IBA’s • The future third phase integrates complete devices as IBA-like components TNO Defense and Security, Ronald Poell

  5. Rational of IBA’s • Transforming static information into an IBA is only useful when the associated behaviors provide new possibilities. • Most of the behaviors can be implemented in traditional non-distributed systems, but are extremely difficult to realize in a distributed (not always perfectly interconnected) environment. TNO Defense and Security, Ronald Poell

  6. Behaviors: Information maintenance • In a large scale information system, running for a long time, manual information maintenance cannot be realized. • Each IBA can evaluate the quality and relevance of their information. • Internally • In comparison to their environment: the related IBA’s • In relation to the outside world (non IBA) • Frequencies of evaluation are determined by previous results. • They have their own evaluation frequency models • The activity is distributed over time TNO Defense and Security, Ronald Poell

  7. Behaviors: Information Security • Information coming from a secured source (through authorization, authentication and encrypted transmission) exist in a non secured form on a local device (most actual systems). • IBA’s can move to a device and reside their in an encrypted form. • They are responsible for releasing their information each time it is requested. • Information Bound Security • Availability • IBA’s can be cloned and distributed • Several methods for assuring synchronization are available • Access to IBA’s is on a best effort base TNO Defense and Security, Ronald Poell

  8. Demonstration • The demonstration system is implemented in the SPYSE agent platform (Python). • Actually 19.295 IBA’s • The information they bear comes from the Semantic Network through XML. • A web interface allows the search and the visualization of the available agents. • Memory load is governed through access frequency evaluation • Agents will be equally distribute themselves among the available Information Bearing Agents Systems (IBAS) TNO Defense and Security, Ronald Poell
