Regret, the emotion arising from counterfactual reasoning about action
and inaction, is a powerful tool in the arsenal of trust-reasoning and
enabling technologies. One aspect of the tool, Regret Management, is the
enforcement of a view of System Trust in technological approaches in
order to preserve and encourage respect for concerns such as data
protection, privacy, and cyber-social interaction. Forgiveness, as a
tool in the broad spectrum of computational trust, helps agents reason
about and rebuild relationships that may have been damaged by some
action, and is particularly useful in areas where, as online, cheap
pseudonyms can exist. This talk will examine regret and forgiveness from
the point of view of agents or devices in connected environments, where
humans are present actors, and show how enforcement of regret management
and forgiveness measures may be efficacious.

Steve Marsh is a Research Scientist in the Network Security Group at in
the Communications Research Centre in Ottawa, Ontario, Canada.

His PhD (University of Stirling, 1994) was a seminal work that
introduced the first formalisation of the phenomenon of trust (the
concept of ‘Computational Trust’), and applied it to Multi Agent
Systems. As a milestone in trust research, it brought together disparate
disciplines and attempted to make sense of a vital phenomenon in human
and artificial societies, and is still widely referenced today. Steve’s
current work builds extensively on this model, applying it to network
security, MANETs, and mobile device security.

His research interests include computational trust, trust management,
regret and regret management, and socially adept technologies. He is the
Canadian delegate to IFIP Technical Committee 11: Security and Privacy
Protection in Information Processing Systems. He is an adjunct professor
at UNB (Computer Science), UOIT (Business and IT) and Carleton
University (Systems and Computer Engineering and Cognitive Science).
