Thomas Ristenpart, professor of computer science at Cornell Tech and the Cornell Ann S. Bowers College of Computing and Information Science, has received the Association for Computing Machinery Conference on Computer and Communications Security (ACM CCS) Test of Time Award for his influential 2015 paper on privacy risks in machine learning.

The paper, “Model Inversion Attacks that Exploit Confidence Information and Basic Countermeasures,” was co-authored with Matt Fredrikson, associate professor at Carnegie Mellon University, and Somesh Jha, professor at the University of Wisconsin-Madison.

The award recognizes research that has had a lasting impact on the field of computer security and privacy. The paper was among the first to show how machine learning models — especially those made available through online services — can inadvertently leak sensitive information.
