Basic Properties of the Persona Model

This document proposes a terminology and a model for representation of user data in information systems in the form of “persona” objects. It provides the mechanisms for evaluation how the personae relate to real-world subjects or to each other. A mechanism how to evaluate some anonymity and identity properties is proposed. This paper also describes the linking of personae by the use of shared identifiers. The local, global, persistent and transient personal linking types are considered. The model is used to describe persona linking in the different practical technologies as the example of model applicability.
