Watching TV with the Second-Party
A recent study investigates Automatic Content Recognition (ACR) tracking in smart TVs, focusing on second-party tracking conducted by the TV platforms themselves. The research reveals that ACR can function regardless of how users watch TV and that opting out can halt data transmission to ACR servers. Additionally, the study highlights differences in ACR tracking practices between the UK and the US.
- ▪Automatic Content Recognition (ACR) is a technology used by smart TVs to track viewing activity.
- ▪The study conducted a black-box audit of ACR network traffic on Samsung and LG smart TVs.
- ▪Results indicate that ACR tracking is effective even when the TV is used as a basic external display.
