Northeastern University study finds television ACR opt-out features frequently fail
A study conducted by researchers at Northeastern University reveals that many smart televisions continue to transmit user data even after tracking features are disabled.
Researchers at Northeastern University examined 12 smart television models from 10 manufacturers to evaluate the effectiveness of Automatic Content Recognition (ACR) opt-out settings. The investigation sought to determine whether users can successfully prevent their devices from collecting and sharing viewing habits.
While most tested brands, including LG, Amazon Fire TV, Sony, and Vidaa OS-based systems, successfully ceased data transmission upon user request, others failed to comply. The study identified that Samsung and Roku devices continued to transmit data despite activation of opt-out settings. Furthermore, a Vizio television model showed no change in behavior after the tracking features were disabled.
This research highlights a persistent lack of transparency in how consumer electronics manage privacy preferences. As connected devices become primary hubs for home media consumption, the findings suggest that consumer control over personal data remains inconsistent across the hardware industry.
