Modelling the relationship between trust and privacy in network environments

In network environments, the entities that connect to or interact with each other may know very little about each other or without prior knowledge at the beginning of an interaction. Therefore, in many cases, before a serious interaction begins, trust must be established between the interactive entities. During trust establishment, an entity may require the other entity to provide some information that could contain some privacy about the entity, leading to privacy loss. On the other hand, such information exchange can help establish trust between the interactive entities. Consequently, it is important to understand the relationship between trust and privacy. In this paper, we study the relationship between trust and privacy in network environments based on game theory in which we consider the facticity of the information that the entities exchanged. Through some application scenarios, we show how our model can be applied in network interactions between entities.
