Brian Levine gave an invited talk at the 2019 USENIX Security Symposium in Santa Clara, California on August 15. The talk "Shining Light on Internet-based Crimes Against Children" discussed measurements of Internet-based crimes against children from his research, and demonstrated that forensic tools can be designed to proactively rescue children, especially those too young to speak and report their abuse, and others silenced by fear. Levine also discussed tension between the intent of privacy enhancing technologies and how they are unfortunately leveraged for this crime. The talk can be viewed online.
