Smart TV data privacy and tracking concerns

Researchers and security experts have identified privacy concerns regarding data collection practices on smart televisions. A study by Northeastern University found that certain models, including those using Samsung Tizen, Vizio OS, and Roku OS, continued to transmit data via Automatic Content Recognition (ACR) technology even after users had opted out of advertising tracking.

Further investigations by security researcher log4j have highlighted specific concerns regarding Samsung Smart TVs running the Tizen operating system. The research indicates that these devices may record and catalog background ‘audio events’, such as a child crying or a dog barking, and transmit this information to Samsung servers as telemetry data. While Samsung maintains these functions are part of its ‘Pet Care’ and ‘Family Care’ features within the SmartThings ecosystem, critics have raised issues regarding the transparency of these data transmissions.

Recent findings from log4j suggest these devices may continuously analyze ambient noise to create advertising profiles, potentially sharing data with over 400 partner companies. The telemetry system reportedly includes counters for specific audio events. Furthermore, research suggests that even models lacking built-in microphones may attempt to access audio by searching for connected Bluetooth devices or soundbars. The investigation also noted that TVs use regional neural networks to track user behavior within applications like YouTube, including the monitoring of skipped advertisements. Samsung has not yet issued a formal response to these latest allegations.
