Palmer Luckey, founder of defense technology company Anduril, highlighted potential national security concerns over Automatic Content Recognition (ACR) technology in smart TVs that captures screen content without user awareness.
In a post on X, Luckey responded to a thread detailing ACR tracking. He stated that “unbelievable amounts of sensitive and classified information is captured, scraped, and sent back to foreign nations” and that users have no idea their TV or monitor functions as a surveillance tool.
Luckey referenced a peer-reviewed study that examined ACR in Samsung and LG smart TVs. The study found that the technology periodically captures visual fingerprints of on-screen content and transmits them to the manufacturers’ servers.
The paper, titled “Watching TV with the Second-Party: A First Look at Automatic Content Recognition Tracking in Smart TVs,” was published in the Proceedings of the 2024 ACM Internet Measurement Conference. Researchers from UC Davis, University College London, and Universidad Carlos III de Madrid conducted the analysis.
According to the study, LG TVs sent ACR data roughly every 15 seconds, while Samsung TVs sent data roughly every 60 seconds. The tracking occurred even when the TV was used solely as an external monitor via HDMI connection from a laptop, game console, or cable box.
The researchers captured network traffic in controlled tests on U.S. and U.K. models. They noted that ACR is enabled by default during initial setup and that opt-out options exist but are not prominently displayed in the user interface.
Luckey described the issue as a massive and growing problem for American national security. He added that he was only half-joking when he previously suggested smart TVs should be illegal.
The study focused on the technical behavior of ACR systems and did not identify specific recipients of the data or confirm transmission of classified information. It highlighted differences in tracking behavior between regions.
No immediate public response from Samsung or LG to Luckey’s comments or the specific study was available as of April 18, 2026. The researchers recommended greater transparency and easier opt-out mechanisms for users.
