FP-Block usable web privacy by controlling browser fingerprinting Joint work with Sjouke Mauw (UL), Christof Ferreira Torres (UL) OUtline Part 1: introduction Part 2: thwarting 3 rd party fingerprint-based web-tracking Introducing

  1. More ways to fingerprint [W2SP11] – fingerprinting JavaScript implementations Hooray for the speedwars! [W2SP12] – fingerprinting HTML5 font rendering All Arials are equal... except most aren't. [W2SP13] – fingerprinting JS engine errors. “Foutje, bedankt.” 64 / 112

  2. More ways to fingerprint [W2SP11] – fingerprinting JavaScript implementations Hooray for the speedwars! [W2SP12] – fingerprinting HTML5 font rendering All Arials are equal... except most aren't. [W2SP13] – fingerprinting JS engine errors. “Foutje, bedankt.” Clock skew can be passively detected, proxies don't help. 65 / 112
