🚨Smart TVs Leak Data Despite User Opt-Outs
Your TV may be spying on you even when you say no
TL;DR
Northeastern University researchers found that Samsung, Vizio, and Roku TVs continue sending data to ACR endpoints after users opt out of tracking. This raises serious privacy concerns for smart TV users.
Researchers at Northeastern University have discovered that smart TVs from Samsung, Vizio, and Roku continue sending data to automatic content recognition (ACR) endpoints even after users opt out of tracking. This behavior, which spans eight operating systems across 12 TVs from 10 manufacturers, covers about 95% of smart TVs in the U.S. The study, which involved 5,943 controlled experiments, highlights potential privacy violations by major TV brands. The findings are particularly concerning for users of Samsung's Tizen OS, where traffic consistent with ACR tracking remained present in 30 out of 30 first-party streaming app measurements and 41 out of 60 antenna measurements, even after opting out. This raises significant questions about transparency and user control over data collection on smart TVs.
Key Points
Northeastern University researchers conducted 5,943 controlled experiments on 12 smart TVs from 10 manufacturers.
Samsung's Tizen OS showed ACR-like behavior in 30 out of 30 first-party streaming app measurements despite user opt-out.
Vizio TVs send network traffic to Amazon Kinesis, a consistent ACR endpoint, even after disabling tracking.
Roku TVs exhibit ACR-like behavior only when using The Roku Channel app, as disclosed in Roku's terms of service.
The study covers approximately 95% of smart TV operating systems used in the United States.
Why It Matters
If you own a smart TV from Samsung, Vizio, or Roku, your privacy settings might not be as effective as you think. The study reveals that these TVs continue to send data to ACR endpoints even after users opt out, raising serious concerns about data privacy and transparency. This affects millions of users and highlights the need for clearer privacy policies and more robust user controls.
