Trail re-identification
The trail re-identification approach (Trail Re-Identification:Learning Who You Are From Where You Have Been, Bradley Malin et al., 2013) was developed for linking genomic data to their identified users whose records are publicly available in various databases.
The concept of trail re-identification includes de-anonymising users by collecting network data and then mapping their anonymised traces with IP addresses, matching IP addresses with Tor hidden services using traffic analysis Trawling for Tor Hidden Services: Detection, Measurement, Deanonymization, Alex Biryukov, Ivan Pustogarov, Ralf-Philipp Weinmann, 2013, and tracking users by detecting their fingerprints in web browsers (visited web pages in the browser’s history).
