Localized Delimited Release: Combining the What and Where Dimensions of Information Release
Paper in proceedings, 2007

Information release (or declassification) policies are the key challenge for language-based information security. Although much progress has been made, different approaches to information release tend to address different aspects of information release. In a recent classification, these aspects are referred to as what, who, where, and when dimensions of declassification. In order to avoid information laundering, it is important to combine defense along the different dimensions. As a step in this direction, this paper presents a combination of what and where information release policies. Moreover, we show that a minor modification of a security type system from the literature (which was designed for treating the what dimension) in fact enforces the combination of what and where policies
