Discover Device Fingerprinting Technology

The growing sophistication of fraudsters has created an urgent need for a more reliable method of identifying online users than cookies. Device fingerprinting is a powerful new solution that strengthens security, provides enhanced user experiences, and helps companies identify patterns of suspicious activity. Learn more

In simple terms, device fingerprinting takes advantage of the way apps and websites talk to your computer or mobile phone’s hardware. For example, when you visit a website, your browser automatically gives that site information about the hardware in your device (screen size, CPU type, and so on). That info is combined with other unique device characteristics to create a digital fingerprint that’s very unlikely to match another device within the system.

Device fingerprints can be enriched with information like screen resolutions, fonts, plugins, and even mouse movements to provide a more accurate and reliable recognition signal. This is particularly important because devices aren’t static entities — they change over time. Things like software updates and device sharing can fundamentally alter a device’s fingerprint. Also, networks and environment can affect how a device is recognized.

Each time a device accesses a website or app, its fingerprint is generated anew based on the current data points. This fingerprint is then compared to the existing fingerprints on record. If there’s a close match, the device is considered recognized and can access the website or app without additional verification. If there’s a significant discrepancy, it may indicate a new device or fraudulent behavior and could trigger more robust authentication steps.
