Browser spoofing: what it is and how spoofed browsers give themselves away
What browser spoofing is, what attackers fake (user agent, OS, screen, timezone), and how a spoofed browser betrays itself through signals that disagree.
What is WebGL fingerprinting? How the GPU gives a device away
WebGL fingerprinting identifies a device by how its GPU renders 3D graphics. How it works, what it reveals, and how it differs from canvas.
What is font fingerprinting? How your installed fonts identify you
Font fingerprinting identifies a device by which fonts are installed, read from how text renders. How it works, what it reveals, and how stable it is.
What is audio fingerprinting? The browser technique, explained
Audio fingerprinting identifies a device by how it processes a sound signal in the browser. How it works, what it reveals, and how stable it is.
What is browser fingerprinting? Detection methods + countermeasures
Browser fingerprinting identifies a device from 100+ datapoints. Learn how canvas, WebGL, and IP signals work, plus detection methods and countermeasures.
What is canvas fingerprinting? How it works and why it is so stable
Canvas fingerprinting identifies a browser by how it renders a hidden image. How it works, what it reveals, how stable it is, and its role in fraud detection.
