Bargav Jayaraman presented our work on privacy-preserving machine learning at the 32nd Conference on Neural Information Processing Systems (NeurIPS 2018) in Montreal.
Distributed learning (sometimes known as federated learning) allows a group of independent data owners to collaboratively learn a model over their data sets without exposing their private data. Our approach combines differential privacy with secure multi-party computation to both protect the data during training and produce a model that provides privacy against inference attacks.
Three SRG posters were presented at USENIX Security Symposium 2018 in Baltimore, Maryland:
There were also a surprising number of appearances by an unidentified unicorn:
I helped organize a summer camp for high school teachers focused on cybersecurity, led by Ahmed Ibrahim. Some of the materials from the camp on cryptography, including the Jefferson Wheel and visual cryptography are here: Cipher School for Muggles.

Earlier this week, 25 high school teachers – including 21 from Virginia – filled a glass-walled room in Rice Hall, sitting in high adjustable chairs at wheeled work tables, their laptops open, following a lecture with graphics about the dangers that lurk in cyberspace and trying to figure out how to pass the information on to a generation that seems to share the most intimate details of life online.
I co-organized, with Homa Alemzadeh and
Karthik Pattabiraman, a
workshop on trustworthy machine learning attached to DSN 2018, in
Dependable and Secure Machine Learning.
