The Fourthline Formula advantages

1. ID verification

Verify 3,500-plus documents using hundreds of AI analyzers and proprietary OCR/NFC technology, including hard documents (e.g., Italian paper ID). Extract personal details to avoid friction and verify documents as secondary ID (e.g., proof of address).

2. Biometric verification

Use advanced 3D technology and photometric algorithms to match a selfie or short video to the ID document. Escalate to a four-eye expert review if AI doesn’t return conclusive results.

3. Database checks

Check 500-plus databases, including sanctions/watchlists, PEP, police databases, adverse media as well as country-specific databases (e.g., Cifas). Identify hits and eliminate false positives through our proprietary software.

4. ID authenticity

Perform a series of checks to establish whether a document is truly authentic. Leverage AI to localize and mark security features on a randomized basis with a full audit trail.

5. Data consistency

Create a plot which visualizes the consistency of data by extracting and comparing many visible and invisible data points (e.g., geo location, device metadata, and address).

6. Joint forces

Collaborate on flagging money mules, professional ID fraudsters, and other high-risk sign-ups through the biggest European GDPR-compliant solution for financial institutions.

7. Second opinion

Use highly trained fraud experts -including former police officers- for a second opinion on thousands of automated checks. The human eye blocks fraudsters attempting to fool the algorithms.

8. Daily monitoring

Catch recurring or colluding fraudsters through daily monitoring. Find overlapping data points and statistical anomalies with our Enhanced Fraud and Profiling Investigations.
