Practical research guides
Connect device evidence to authentication and account abuse
Connect device recognition to takeover, signup and sharing decisions, with named provider options, passwordless-login boundaries and recovery evidence.
Use recognition for benefit eligibility without overclaiming identity
Use device relationships to review repeat trials, promotions and referrals, with grant-ledger controls, shared-device cases and identification costs.
Design browser recognition and a reliable identity evaluation
Compare fingerprint APIs, browser and audio signals, cookieless recognition and visitor metrics, with shared-device cases and trusted account joins.
Combine device and connection signals without mixing their meaning
Combine proxy API results, IP reputation, location evidence and protocol fingerprints while preserving client-IP trust, uncertainty and device history.
Trace a device event through commerce and acquisition decisions
Trace device evidence through guest orders, payment checks, returns and acquisition, with commerce-vendor choices and separate authorization records.
Select identity and fraud software by its returned evidence
Compare device and fraud products by returned evidence, self-serve pricing and operating scope, including adjacent identity, voice and support tools.
