September 4–11, 2026 · First edition. One new publication met the relevance, date and evidence checks. New research: CrossLink, below. Standards and regulatory updates: none verified for inclusion. No newly dated device-free home-sensing performance study or consumer-control revision was verified; older material has not been relabeled as new. This is a selective public-source scan, not proof that no other work appeared.
CrossLink: Breaking Location Privacy by Linking Device Identifiers Across Protocols
What changed
The CrossLink paper links rotating LTE, Wi-Fi and BLE identifiers to reconstruct device traces. The reported 83% complete-trace recovery versus 22% for the best single-protocol baseline comes from simulation.
Why it matters
Privacy controls need joint evaluation across radios; Wi-Fi identifier randomization alone is not an end-to-end guarantee.
Evidence limits
Not device-free body sensing or household occupancy validation. Results depend on localization assumptions and receiver coverage; peer review was not verified.
Read in full?
Read in full. The evaluation caveats matter as much as the headline privacy result.
