Mike Rosulek, assistant professor of computer science in the College of Engineering at Oregon State University, received a Visa Faculty Research Award to advance methods of customer privacy and fraud detection.

“We’ve known for several decades that cryptography can protect not just data at rest, but also data in use, at least in principle. Finally, in the last several years these cryptographic ideas have been improved to become truly practical,” Rosulek said.

Rosulek and his colleague at Visa, Payman Mohassel, will be working to improve a tool from cryptology called private set intersection, which allows two parties to find items in common on two separate lists without revealing any other information from the lists.

Their research will help make complicated queries faster to process. For example, a company may want to know how many customers they have in common with another company without revealing who those customers are.

The funds will support one graduate student for a year who will be helping to develop new prototypes that would make advanced cryptography practical for companies.

“This award demonstrates that industry leaders see the potential of advanced cryptography to protect data during use and solve real-world privacy challenges,” Rosulek said.
