Google Chrome Under Scrutiny for Fingerprinting Privacy Gap
Privacy experts highlight Google Chrome's absence of fingerprinting defenses as a growing data risk.
Why it matters: Legal professionals face rising compliance obligations under laws like GDPR and CCPA, especially when browser fingerprinting exposes sensitive information and evades traditional privacy controls. Chrome's policy puts users and firms at heightened risk of noncompliance and targeted tracking.
- Google Chrome does not include built-in protections against browser fingerprinting.
- Studies show fingerprinting scripts can identify users with up to 94% accuracy (Eckersley, EFF, 2010).
- 25% of the world's top 10,000 websites use fingerprinting technology (University of Iowa, 2020).
- In February 2025, Google officially permitted advertisers to leverage device fingerprinting.
A lack of built-in fingerprinting protections in Google Chrome has renewed concerns about online privacy and regulatory compliance, as called out by privacy consultant Alexander Hanff and leading privacy researchers.
- Browser fingerprinting collects distinct configurations—like screen resolution, fonts, and device specs—forming a unique user profile. According to research by Peter Eckersley of the Electronic Frontier Foundation (EFF), this identifies users with up to 94% accuracy, making it a powerful tracking method even when cookies or Incognito mode are used.
- A University of Iowa study (2020) found 25% of the world’s top 10,000 sites deploy fingerprinting scripts—often without user notice or consent.
- Unlike tracking cookies, fingerprinting is far less visible and operates beyond standard browser controls, raising the risk of violation of laws like the GDPR and California's CCPA, both of which require transparency and user control over personal data collection.
As reported by independent privacy analysts, Google in February 2025 formally permitted advertisers to use device fingerprinting, complicating compliance for privacy-sensitive industries. The EFF and legal privacy advocates warn that fingerprinting is designed specifically to sidestep conventional privacy tools and can go undetected by users and organizations.
Legal and compliance officers should evaluate Chrome usage in their organizations and consider additional mitigation—whether via browser extensions or privacy-focused alternatives—to reduce compliance, regulatory, and reputational risks arising from fingerprint-based profiling.
By the numbers:
- 94% — Accuracy of user identification via fingerprinting (EFF, 2010)
- 25% — Share of top 10,000 websites using fingerprinting scripts (University of Iowa, 2020)
- Feb. 2025 — Google permitted device fingerprinting for advertisers
Yes, but: Some privacy-focused browsers, such as Mozilla Firefox and Apple Safari, offer partial protections against fingerprinting, but none eliminate the risk entirely.
What's next: Stakeholders expect further privacy guidance from EU data protection authorities addressing browser fingerprinting's compliance implications.
