Deepfake Detection

IllumaSHIELD is a voice security platform for contact centers used by lenders and fintech companies. It provides passive voice authentication that verifies callers during natural conversation by matching their voice against a stored voiceprint, without requiring PINs, security questions, or repeated phrases. The platform detects high-risk activity during live calls, including mismatched voiceprints, repeat fraud patterns, suspicious phone number behavior, and indicators of synthetic or AI-generated voice used in deepfake impersonation attempts. When suspicious activity is detected, agents receive silent alerts to respond without alerting the caller. IllumaSHIELD includes collaborative intelligence that shares risk signals related to accounts, phone numbers, and voiceprints across the organization when an agent flags suspicious behavior. It also applies adaptive multi-factor authentication, applying step-up verification only when risk levels warrant additional checks. Beyond live agent calls, the platform extends voice authentication into IVR systems, automated phone workflows, and virtual agents (IVA) to support secure self-service transactions such as balance checks, payments, and account updates. Use cases include loan servicing, mortgage servicing, auto lending support, BNPL and digital lending platforms, account and payment change requests, and collections and recovery teams.</description> <parameter name="summary">Real-time voice authentication and deepfake/fraud detection for lender and fintech call centers
