Mitigating Technology Abuse in Intimate Partner Violence and Encrypted Messaging
Monday, February 27, 2023 - 4:00pm to 5:00pm
NOTES: The Triangle Computer Science Distinguished Lecturer Series is cosponsored by UNC Computer Science and NC State Computer Science. Snacks and drinks will be provided. ABSTRACT: Computer security is traditionally about the protection of technology, whereas trust and safety efforts focus on preventing technology abuse from harming people. In this talk, I'll explore the interplay between security and tech abuse, and make the case that trust and safety represent an important frontier for computer security researchers. To do so, I'll draw on examples from two lines of my recent work. I will provide a brief overview of our work on technology abuse in the context of intimate partner violence (IPV), and also discuss how basic security tools like encrypted messaging need to be adapted in light of tech abuse. SPEAKER BIO: Thomas Ristenpart is an Associate Professor at Cornell Tech and a member of the Computer Science department at Cornell University. Before joining Cornell, he was an Assistant Professor at the University of Wisconsin-Madison and completed his PhD at UC San Diego. His research spans a wide range of computer security topics, with recent focuses including digital privacy and safety in intimate partner violence, anti-abuse mitigations for encrypted messaging systems, improvements to authentication mechanisms including passwords, and topics in applied and theoretical cryptography. His work is routinely featured in the media and has been recognized by a number of distinguished paper awards, two ACM CCS test-of-time awards, an Advocate of New York City award, an NSF CAREER Award, and a Sloan Research Fellowship.
