Abstract

"Accountability" is used often in describing computer-security mechanisms that complement preventive security, but it lacks a precise, agreed-upon definition.  Here, we categorize some of the many ways in which this term is used and argue for a punishment-focused view of "accountability."  We formalize our view in a utility-theoretic way and then use this to reason about accountability in computing systems.  We also survey mechanisms providing various senses of accountability as well as other approaches to reasoning about accountability-related properties. 

This is joint work with Joan Feigenbaum and Rebecca Wright.
