The W3C Do Not Track specification introduced the DNT: 1 HTTP request header and navigator.doNotTrack DOM property to signal user opt-out of cross-site tracking.
Global Privacy Control (navigator.globalPrivacyControl) modernizes tracking opt-outs by providing legally enforceable data sale/sharing opt-out signals under CCPA, CPRA, and GDPR privacy frameworks.
Combining DNT/GPC audit tools with strict Referrer policies (strict-origin-when-cross-origin) ensures user web sessions minimize digital identity exposure to third-party ad networks.
