Privacy-Respecting Proactive Forensics

Abstract
Quick! Something bad has happened on the Internet. The traditional
approach for determining the cause of the problem is to dig through
logs and other forensics trails left by applications. These
traditional approaches, while helpful, are limited in either: (1)
their respect for the privacy of parties in the common case when there
is no incident to investigate or (2) the forensic trails are weak and
spoofable. These limitations beg the question: Can we create
applications -- and maybe even a new Internet -- that provide stronger
yet also more privacy-respecting forensics trails by default? I will
describe two ongoing projects centered on meeting these goal. The
first project targets stronger but privacy-respecting forensics trails
at the IP level. The second targets stronger but privacy-respecting
methods for recovering lost or stolen mobile devices.
