Prize Challenge

Privacy-Enhancing Technologies (PETs) Prize Challenge: Advancing Privacy-Preserving Federated Learning

Privacy-enhancing technologies (PETs) present an opportunity to harness the power of data in a manner that protects privacy and intellectual property, enabling cross-border and cross-sector collaboration to solve shared challenges. Innovators in these challenges developed state-of-the-art privacy-preserving federated learning solutions that help to tackle the barriers to the wider use of these technologies. Ran in parallel with the challenge sponsored by the U.K.’s Center for Data Ethics and Innovation, the U.S. prize challenge was co-sponsored by NIST and the National Science Foundation, in coordination with the White House Office of Science and Technology Policy.

The U.S.-U.K. collaboration on the PETs prize challenges was first announced at the Summit for Democracy in December 2021. In addition to competing for a combined U.S.-U.K. prize pool of $1.6 million (£1.3 million), winning solutions was featured at the 2nd Summit for Democracy in the spring of 2023.
