Device Fingerprinting
What is device fingerprinting?
Device fingerprinting is a technique that uses attributes like operating system, browser information, language settings, screen size, fonts, installed plugins, and especially IP address to “fingerprint” a unique device/browser. Used by some attribution providers, other adtech firms, and consumer-facing websites, fingerprinting is considered somewhat unsavory for its invasive approach to privacy. As a result, major browser providers have been taking steps to make it harder to fingerprint devices.
