Who ranks for “device fingerprinting”

How It Works

When a device interacts with a website or app, a script gathers dozens of background attributes and combines them into a unique identifier hash. Key data points collected include: Plaid

Hardware: Screen resolution, CPU type, battery level, and audio output capabilities. Software: Operating system version, installed fonts, available plugins, and user-agent string. Network: IP address, ISP, and connection type. Advanced Techniques: Methods like Canvas (how the browser renders graphics) and WebGL detect microscopic differences in a device's graphics hardware.

Fraud Prevention: By identifying if a device is connected to a history of suspicious behavior, financial institutions and e-commerce platforms can block account takeovers and payment fraud. Frictionless Authentication: Recognizing returning devices allows platforms to skip redundant two-factor authentication (2FA) or OTP prompts for trusted users. Targeted Analytics: It enables services to recognize anonymous visitors and personalize content across browsers without requiring a login.
