Digital Fingerprinting
What is Digital Fingerprinting?
Digital fingerprinting is a tracking technique that identifies users based on the unique configuration of their device, rather than cookies. Scripts collect data points such as screen resolution, installed fonts, operating system version, and battery level. When combined, these data points create a unique "fingerprint" that can track a user across the web even if they delete cookies or use Incognito mode.
Why does Digital Fingerprinting matter?
Fingerprinting is considered invasive because it is difficult for users to detect or prevent. Because it happens silently, it undermines user transparency. Privacy regulations like GDPR classify fingerprinting as "accessing information on a user's terminal equipment," meaning it requires the same high level of consent as tracking cookies. Browsers like Safari actively obfuscate this data to prevent fingerprinting.
FAQs about Digital Fingerprinting
It is more "persistent" for the tracker, but less secure for the user's privacy. Unlike cookies, which a user can clear, a user cannot easily change their screen resolution or installed fonts to reset their identity.
Yes. Although laws often mention "cookies," they cover "online identifiers." Any technology used to single out an individual and monitor their behavior falls under the scope of global privacy frameworks.
Safari simplifies the system information it reveals. Instead of showing your exact device model, it presents a generic profile that looks identical to millions of other Safari users, making it impossible to single you out.
