Brian Lynn



I am on staff in the College of Information and Computer Sciences, and a member of the CS Forensics Lab. I am researching and developing technologies to prevent child exploitation on the Internet, with an emphasis on file-sharing forensics. I have also worked on cell phone forensics.

I previously worked on mobile and disruption tolerant networking, specifically the Diverse Outdoor Mobile Environment (DOME). Much of our later work on DOME was in conjunction with NSF's Global Environment for Network Innovations (GENI). Our final GENI project involved deploying WiMAX in our DOME mobile test bed. We installed a WiMAX base station in the LGRT and placed virtualized clients on our mobile nodes (UMass Transit buses). As part of our work on disruption tolerant networking we released the RAPID routing protocol for DTN.

Before joining UMass I worked for Hewlett-Packard in the Bay Area. My final position with HP was as a research manager at HP Labs in the now defunct Linux Technologies Project. Prior to leaving HP Labs I was involved in a project working on network processor partitioning and asynchronous I/O, helped found the Gelato Federation, and served on HP's Open Source Review Board.

On Sept 17, 2015, Brian and other professors from UMass are hosting the New England Security Day, with talks and panels involving faculty from around the region.

Between April 2012 and August 2015, over 300 children were rescued from sexualy abusive situations by investigators using our forensics tools.

Our paper Sybil-Resistant Mixing for Bitcoin was presented by Pinar Ozisik at the ACM Workshop on Privacy in the Electronic Society (November 2014).

Our paper Efficient Smart Phone Forensics Based on Relevance Feedback was presented by Robert Walls at the ACM Workshop on Security and Privacy in Smartphones and Mobile Devices (November 2014).

Our article Efficient Tagging of Remote Peers During Child Pornography Investigations has appeared in IEEE Transactions on Dependable and Secure Computing (September 2014).

Our paper Location Privacy without Carrier Cooperation was accepted and presented at the IEEE MoST 2014 workshop .

Our paper on Measurement Child Pornography Trafficking was runner-up for Best Paper at WWW 2013. Over 800 papers were submitted and 125 accepted to the conference.

Brian Levine is giving a Keynote talk at SYSTOR 2013 Conference in Haifa, Israel, held in cooperation with USENIX and the Technion Center of Excellence (TCE) this June. The talk will be on "Fighting Internet-based Sexual Exploitation Crimes Against Children".

We were honored to have our work referenced in a very important January 2013 New York Times Magazine article on victim restitution.

The United States Sentencing Commission's Report to Congress: Federal Child Pornography Offenses contains many references to our research, including Robert Walls' paper on "Effective Digital Forensics".

Our work was featured in the Dept. of Justice's National Strategy for Child Exploitation Prevention and Interdiction: A Report to Congress.
