GoKawiilResearch: Samsung, Vizio and Roku smart TVs keep tracking data after opt-out
A Northeastern University study found that smart TVs running Samsung, Vizio and Roku operating systems continued transmitting data to automatic content recognition (ACR) servers even after users disabled tracking in settings. Researchers tested 12 smart TVs across eight operating systems from 10 manufacturers, running nearly 6,000 controlled experiments to monitor network traffic to and from ACR endpoints.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest that privacy controls offered by major smart TV makers may not function as advertised, potentially exposing users to continued surveillance of their viewing habits despite opting out. Because ACR operates at the operating-system level, the researchers argue their results likely extend to the vast majority of smart TVs sold in the US, even though only a small sample was directly tested.
- Northeastern researchers found smart TVs from Samsung, Vizio and Roku sent ACR data even after users opted out of tracking.
- The study covered 12 TVs across 8 operating systems, representing about 95% of smart TV OSes used in the US.
- Some ACR traffic was identifiable through self-disclosing domain names containing terms like 'acr' or provider names.
