# Enhanced Identity Check ### 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](https://docs.complycube.com/documentation/product-guides/biometric-and-liveness-verification/identity-check). {% hint style="info" %} 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](https://docs.complycube.com/documentation/product-guides/biometric-and-liveness-verification/face-authentication-check) for future interactions. {% endhint %} {% hint style="info" %} This check can only be performed through our [Hosted Solution](https://app.gitbook.com/s/lv7UhJvTbxeq4s3KwQpn/web-integrations/hosted-solution-quick-guide), [Web SDK](https://app.gitbook.com/s/lv7UhJvTbxeq4s3KwQpn/web-integrations/web-sdk-quick-guide), or [Mobile SDKs](https://app.gitbook.com/s/sw26JqCBnT6AEIbxAYyk/quick-guides/mobile-sdk-guide). {% endhint %} {% hint style="info" %} [Learn about the Enhanced Identity Checks API.](https://app.gitbook.com/s/kAhgmUKSf8CFUFVL3GEe/check-types/enhanced-identity-check) {% endhint %} ### 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. *** ![Enhanced Identity Check Overview](https://1615271746-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FKyFKMqftsmT6qln9zo5y%2Fuploads%2F2LNsQ9VFfPhkm2SeLLXY%2Fenhanced_identity_check_service.png?alt=media\&token=0114cf59-36d3-447a-8fbb-8e6904f81645) *** **Detailed verification checks**
AnalysisVerifications Performed
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.
