Project Description
The PIMAWAT Project (Collaborative Research: IMR: MM-1-B:
Privacy in Internet Measurements Applied To WAN and Telematics, supported by NSF CISE) will
demonstrate new methods to provide data networking datasets that
respect end-user privacy, but are still able to support new research
in allow network protocols, security, privacy, and machine learning.
Our insight is that most data today sent over the wide-area network (WAN)
is encrypted, so our challenge is to demonstrate what data is
encrypted, detect and scrub any remaining leaks, and finally
anonymize the metadata (who talks to whom) before sharing data.
The intellectual focus of PIMAWAT will be to develop new methods to
anonymize network traffic at scale, then use those new algorithms to
evaluate potential data leakage, and demonstrate that real-world data
sources can be scrubbed for sharing while respecting privacy.
The broader impacts of PIMAWAT will be to make it easier for researchers to
collect and share network data through new tools and best-practices
for privacy-respecting data scrubbing.
Support
PIMAWAT is supported by NSF/CISE
as a CISE IMR
award CNS-2319409.
