Information Sciences Seminar——Towards Interpretable Fingerprinting against Social Media Pages

Abstract
Despite various mechanisms such as SSL/TLS have been deployed to provide confidentiality and data authentication for web infrastructure, traffic analysis attacks are still able to deteriorate user privacy in web browsing. In this work, we investigate the web page fingerprinting attacks which aim to identify the particular web pages a user has browsed. We find that the traffic occurring while the web browser is rendering a web page exhibits temporal patterns distinguishable by machine learning algorithms. We characterize those patterns as CDN bursts, and use features extracted from CDN bursts to empower classification algorithms to achieve high classification accuracy (96%).
