Do you trust that your smart devices stop tracking you when you change privacy settings?
Northeastern University researchers found that certain smart TVs continue to transmit network traffic consistent with content recognition after users opt out of data tracking. The study covered 12 televisions from 10 manufacturers representing 95% of the US operating system market.
Why it matters
Automatic content recognition samples audio and video to identify programs for advertising and audience measurement, raising significant privacy concerns when user preferences are ignored. While some platforms successfully suppress this traffic, the persistence of data transmissions on other models highlights a lack of transparency for consumers.
Researchers performed 5,943 controlled experiments across 12 televisions from 10 manufacturers. The study analyzed eight operating systems that account for 95% of the total US smart TV market.
The players
Northeastern University
This is a private research university in Boston that conducted the smart TV privacy study.
Samsung
This multinational electronics corporation produces the Tizen operating system for its smart TVs.
Vizio
This American publicly traded company manufactures television sets and soundbars featuring the SmartCast platform.
Roku
This American company provides a popular streaming hardware and software platform for televisions.
The details
Tests revealed that Samsung Tizen devices and Vizio SmartCast models continued sending traffic to content recognition endpoints despite user opt-out attempts. Researchers also noted that Roku's privacy settings failed to stop data transmission related to its own streaming service, though LG, Amazon, Sony, and VIDAA systems functioned as expected.

Industry Dynamics
The findings from Northeastern University's smart TV data privacy research highlight a significant gap between consumer privacy expectations and corporate data collection practices. This study challenges the industry standard of opt-out settings, suggesting that current manufacturer policies may not be as effective as users believe.
Consumers who have manually disabled tracking in their TV settings may still be having their viewing habits monitored by certain manufacturers. Because encryption hides the specific data being sent, users currently have no way to verify if their opt-out choices are actually stopping the collection of their media consumption data.
The takeaway
Privacy-conscious users should consider using external streaming devices that offer stricter control over data transmission, as built-in smart TV features may bypass user settings. It is important to remember that opt-out features on current television operating systems do not guarantee total protection from automatic content recognition.
