Samsung TV kept sending ACR viewing data after opt-out, study finds

A Northeastern University study found a Samsung smart TV continued sending traffic consistent with automatic content recognition tracking after researchers disabled the feature. The opt-out fully worked on only four of ten tested platforms: LG webOS, Google TV on Sony, VIDAA and Amazon Fire TV; Vizio's setting had no observable effect.

• Samsung TV sent ACR-like traffic after tracking was turned off
• Opt-out fully worked on webOS, Sony Google TV, VIDAA and Fire TV
• Vizio's opt-out had no observable effect on tracking traffic
• 82% of US households own a smart TV capable of ACR tracking
