INVITED TALK I

Depicting Social Trust in a Digital World

ABSTRACT
In recent years, computer science researchers have investigated various definitions of trust and its management.  However, even nowadays, there is still no widely accepted definition of trust, mainly because trust interpretation is in the eye of the beholder.  Creating a universally acceptable set of rules and mechanisms to specify trust is thus a difficult process due to this variety in trust definitions.

Nevertheless, trust is an abstraction of individual beliefs that an entity has for specific situations and interactions.  An entity’s beliefs are not static but they change as time progresses and new information is processed into knowledge.  Trust must evolve in a consistent manner so that it still abstracts the entity’s beliefs accurately. In this way, an entity continuously makes informed decisions based on its current beliefs.

In this talk, I will present trust as a social paradigm and discuss its applicability and management in distributed system environments.  I will discuss how society practices are depicted in virtual collaborative environments and their impact on modeling digital trust.  Some final thoughts on challenges and future directions in this area will be discussed as well.
