FP-Fed: Privacy-Preserving Federated Detection of Browser Fingerprinting
CoRR(2023)
摘要
Browser fingerprinting often provides an attractive alternative to
third-party cookies for tracking users across the web. In fact, the increasing
restrictions on third-party cookies placed by common web browsers and recent
regulations like the GDPR may accelerate the transition. To counter browser
fingerprinting, previous work proposed several techniques to detect its
prevalence and severity. However, these rely on 1) centralized web crawls
and/or 2) computationally intensive operations to extract and process signals
(e.g., information-flow and static analysis). To address these limitations, we
present FP-Fed, the first distributed system for browser fingerprinting
detection. Using FP-Fed, users can collaboratively train on-device models based
on their real browsing patterns, without sharing their training data with a
central entity, by relying on Differentially Private Federated Learning
(DP-FL). To demonstrate its feasibility and effectiveness, we evaluate FP-Fed's
performance on a set of 18.3k popular websites with different privacy levels,
numbers of participants, and features extracted from the scripts. Our
experiments show that FP-Fed achieves reasonably high detection performance and
can perform both training and inference efficiently, on-device, by only relying
on runtime signals extracted from the execution trace, without requiring any
resource-intensive operation.
