Duplicate journeys are referred or rejected based on your configuration. Existing journey IDs are linked for compliance review.

Frequently asked questions

No. Duplicate detection is strictly scoped to a single tenant. No data or biometrics are shared across tenants, meeting GDPR and regional data protection requirements.
The journey is referred or rejected (configurable). The duplicate is flagged in IDWise Studio with the linked journey IDs so compliance teams can review the evidence.
Yes. The Account Duplication Detection block can be placed multiple times in a flow, enabling duplicate checks at different stages, for example after ID submission and again after AML screening.
IDWise uses face biometrics only: the submitted selfie is compared against all previously enrolled selfies in the tenant using a similarity score with a configurable match threshold.
