Abstract
Within a privacy-enhancing identity management system, among other sources of information, knowledge about current anonymity and about linkability of user’s actions should be available, so that each user is enabled to make educated decisions about performing actions and disclosing PII (personal identifiable information).
In this paper I describe a framework for quantification of anonymity and linkability of a user’s actions for use within a privacy-enhancing identity management system. Therefore, I define a model of user’s PII and actions as well as an attacker model. Based thereon, I describe an approach to quantify anonymity and linkability of actions. Regarding practical applicability, a third party service for linkability quantification is discussed.
