Device fingerprinting creates a persistent device identifier from technical attributes such as browser and operating system details, hardware specifications, fonts, language settings, canvas rendering, and potential WebRTC IP leaks, rather than directly identifiable personal information. It is presented as a stronger complement to IP-address verification because VPNs, proxies, and rotating IPs can obscure network locations while device configurations often remain recognizable. Businesses can use fingerprints to identify repeat fraudsters, detect account takeovers, distinguish bots, uncover multi-account abuse, and calculate broader real-time fraud risk scores alongside IP and behavioral signals. The text cites industry reports suggesting fraud reductions of 30–70% and notes that privacy-conscious implementations use hashing, anonymization, limited data collection, and transparent policies. Didit promotes its platform as combining device fingerprinting with behavioral biometrics, machine-learning fraud detection, APIs and SDKs, and risk scoring to reduce fraud and false positives while improving conversion rates.
