Frequently Asked Questions

Leading the way in identity verification worldwide

Face Search 1:N (one-to-many) is a powerful anti-fraud tool that compares a new user's selfie against your entire existing database of verified users. It instantly detects if that person has signed up before, effectively blocking duplicate accounts, bonus abuse, and fraud rings.

During a verification, our system creates a unique biometric template of the user's face. This template is then securely compared against the templates of all other users in your database. Our high-speed search algorithm identifies any potential matches based on a similarity score, all in real-time.

If a match is detected above your configured threshold, the system immediately flags the verification attempt. You receive a detailed report showing the potential match(es), their respective similarity scores, and links to the previous verification sessions, allowing your team to make a confident and swift decision.

Yes, you have full control. You can set custom similarity thresholds to define what constitutes a 'match' for your business. This allows you to fine-tune the balance between preventing fraud and ensuring a smooth experience for users who might have legitimate reasons for re-registering.

You can maintain a private 'blocklist' of biometric templates from known fraudsters. Face Search 1:N automatically checks every new user against this blocklist in real-time. If a match is found, the verification can be automatically declined, stopping bad actors before they even enter your system.

Our system is optimized for speed and scale. Searches are performed in near real-time, typically taking only a few seconds even with hundreds of thousands or millions of user records. This ensures it doesn't add any noticeable delay to your onboarding process.

Absolutely. All biometric data is stored as encrypted templates, not as raw images. The process is conducted within our secure, ISO 27001-certified environment. As the Data Controller, you are responsible for the legal basis of storing and searching this data, and our platform provides the secure tools to do so in a compliant manner.

Face Search 1:N is a premium API service priced at just $0.05 per search request. This highly affordable rate allows you to add a powerful layer of fraud prevention to every single onboarding or verification flow.
