Collaborative Filtering for Community Threats

AI Technologies for Homeland Security

Volume

Papers from the 2005 AAAI Spring Symposium

Contents

We discuss the threats posed by attacks on computer infrastructure, and particularly attacks from distributed, stealthy sources. We propose that these attacks would best be detected by distributed networks of sensors, and that these distributed networks must protect the privacy, confidentiality and anonymity of their members. We briefly outline a network attack detection technique we are working on that is based on privacy-preserving collaborative filtering, and discuss some related work.
