Enhanced Identity Check
Video selfie liveness detection with motion and voice challenges, plus face match, for high-assurance KYC identity verification (ISO-certified PAD Level 2).
About service
An Enhanced Identity Check is a high-assurance biometric identity verification service. Use it for KYC onboarding and video-based identity verification (video KYC).
It combines ISO-certified (PAD Level 2) liveness detection with facial similarity (face match). It analyzes a video selfie with guided motion and voice challenges. It then compares the video face to the photo on an official ID document.
This service uses Presentation Attack Detection (PAD) to reduce liveness fraud. This helps detect advanced spoofing vectors, including:
Printed mask attacks: Where masks with cut-outs are used to mimic real faces.
Printed photo attacks: Where fraudsters use printed photos.
Video replay attacks: Where pre-recorded or virtual videos attempt to simulate liveness.
3D mask attacks: Where silicone or plastic masks are used to impersonate individuals.
In some jurisdictions, video-based identity verification is a regulatory requirement. This check supports those requirements with guided challenges.
If you don’t need video challenges, use Identity Check.
On a successful Enhanced Identity Check, your customer’s facial biometrics will be automatically enrolled (if enabled on your plan). This helps prevent fraud related to multiple registrations under different identities and enables face-based authentication for future interactions.
This check can only be performed through our Hosted Solution, Web SDK, or Mobile SDKs.
Analysis performed
The Enhanced Identity Check performs multiple layers of biometric analysis to validate active liveness and facial similarity. It also flags spoofing and tampering signals.
The diagram below outlines the key analysis categories.
Detailed verification checks
Face Analysis
Facial similarity: Compares the submitted video with the ID photo to confirm both belong to the same person. Returns a confidence score between 0–100%, where 100% indicates a perfect match and 0% indicates no match at all.
Previously enrolled face: Detects if the same face has already been registered using different customer details.
Authenticity Analysis
Spoofed image analysis: Indicates whether the images are manipulated, copied from the internet, or are known blacklisted images.
Liveness check: Confirms the customer is physically present and not a spoof attempt. This involves advanced biometric and anti-spoofing techniques, such as:
3D facial mapping
Skin texture and micro-expression analysis
Pixel-level tampering detection
Virtual camera detection
Mask and disguise recognition
Proprietary anti-spoofing techniques
Returns a confidence score between 0–100%, where 100% indicates a highly reliable live presence and 0% indicates a likely spoof attempt.
Voice challenge analysis: Indicates if the customer has successfully completed the voice challenge.
Action challenge analysis: Indicates if the customer has successfully completed the action challenge.
Integrity Analysis
Face detection: Ensures the expected number of faces are present in the video and that the image quality is sufficient for reliable analysis.
Check duration
An Enhanced Identity Check takes an average of 20 seconds to complete.
