@Scale 2019: Fighting fraud anonymously

Logging is essential to running a service or an app. But every app faces a dilemma: The more data is logged, the more we understand the problems of users, but the less privacy they have. One way to add privacy is to report events without identifying users; however, this anonymity can allow fraudulent logs to be reported. Subodh introduces the problem of fraudulent reporting alongside an approach to using cryptography, including blind signatures, to enable fraud-resistant anonymous reporting. He presents a specific application to ads, demonstrating how fraud-resistant private reporting can be feasible; some different approaches for implementation; and some open problems.
