Anonymity Metrics Revisited

Abstract

In 2001, two information theoretic anonymity metrics were proposed: the "effective anonymity set size" and the "degree of anonymity". In this talk, we propose an abstract model for a general anonymity system which is consistent with the definition of anonymity on which the metrics are based. We revisit entropy-based anonymity metrics, and we apply them to Crowds, a practical
anonymity system. We discuss the differences between the two metrics
and the results obtained in the example.
