Google Expands Digital Fingerprinting to Smart TVs, Consoles, and Connected Devices

Google is expanding its digital tracking capabilities beyond traditional browsers and phones to include smart TVs, gaming consoles, and other connected devices. The rollout of this expanded fingerprinting approach began in February 2025.

What Is Digital Fingerprinting?

Digital fingerprinting collects small technical details about a device -- screen resolution, installed fonts, browser version, operating system, and other attributes -- to construct a unique identifier. Unlike cookies, fingerprints cannot be easily cleared or blocked by users, making this method far more persistent and difficult to control.

The Reversal

This move is notable because Google itself previously criticized digital fingerprinting as a privacy-hostile technique. The company now argues that its approach enables better advertising targeting across an increasingly fragmented landscape of connected devices.

Regulatory Response

The UK Information Commissioner's Office has warned that fingerprinting-based tracking fundamentally undermines user choice and privacy. Unlike cookies, which users can manage through browser settings, fingerprinting operates silently and offers no straightforward opt-out mechanism. Privacy regulators across Europe are closely monitoring these developments.
