- US Customs and Border Protection (CBP) is using phone location data to track individuals of interest.
- The data is partly sourced from real-time bidding (RTB) in online advertising, where ads are served based on demographics.
- Surveillance firms or rogue advertising companies can exploit RTB to collect mobile phone data, including location, without users' knowledge.
- This tracking process is invisible to ordinary phone users but occurs constantly.
- LWN's minimal advertising does not use this RTB system.
