Protecting privacy through metadata analysis

6 Mar

Sandra Siby, Research Associate at Imperial College London, UK

External Presentation (External Speaker)

Metadata, or ‘data about data’ can be a rich source of details and context, revealing information about a user even in the presence of encryption. In this talk, I will discuss ways in which we can use metadata analysis to protect privacy at the network and web level. First, I will demonstrate how metadata analysis can be used by adversaries to perform website-fingerprinting attacks against newly-standardized networking protocols, and how we can develop defenses against such attacks. Second, I will describe how we can use the difficulty in hiding metadata to build robust systems for detecting online advertising and tracking services. Finally, I will outline my vision to build privacy frameworks for understudied scenarios.
