Breaking Anonymity at Scale: Re-identifying the Trajectories of 100K Real Users in Japan
Mobility traces represent a critical class of personal data, often subjected to privacy-preserving transformations before public release. In this study, we analyze the anonymized Yjmob100k dataset, which captures the trajectories of 100,000 users in Japan, and demonstrate how existing anonymization techniques fail to protect their sensitive attributes. We leverage population density patterns, structural correlations, and temporal activity profiles to re-identify the dataset's real-world locatio…

Meta and Yandex are de-anonymizing Android users’ web browsing identifiers
Abuse allows Meta and Yandex to attach persistent identifiers to detailed browsing histories.

Meta und Yandex haben die Browsernutzung von Android-Nutzer'innen mit einer perfiden und bisher unbekannten Tracking-Methode deanonymisiert und damit die strikte Trennung von Apps ausgehebelt.
Das in Websites eingebettete Tracking-Script (also z.B. "Facebook Pixel") konnte sein _fbp-Cookie über einen internen Port (z.B. 127.0.0.0:12387) senden und die Facebook-App hat auf diesem Port gelauscht und das Cookie abgefangen. So wurde ein Webseitenbesuch, bei dem Facebook eing…
