Device Fingerprinting

A fingerprint is a unique hashed string identifier that is generated by combining the hashed values of several device parameters. Thirdwatch’s Fingerprint Software Development Kit (SDK) generates this identifier for the user and passes it to Thirdwatch. When a customer tries to purchase on your website, Thirdwatch creates a unique fingerprint using user, IP, and device details. This helps Thirdwatch flag fraudulent orders.
