# Enhanced Identity Check ### Enhanced Identity Check Overview 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) active 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. * **Deepfake attacks:** Where AI-generated or manipulated facial media attempts to impersonate a real person. * **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](/documentation/product-guides/biometric-and-liveness-verification/identity-check.md). {% 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](/documentation/product-guides/biometric-and-liveness-verification/face-authentication-check.md) for future interactions. {% endhint %} {% hint style="info" %} This check can only be performed through our [Hosted Solution](/documentation/sdks/web-integrations/hosted-solution-quick-guide.md), [Web SDK](/documentation/sdks/web-integrations/web-sdk-quick-guide.md), or [Mobile SDKs](/documentation/quick-guides/mobile-sdk-guide.md). {% endhint %} {% hint style="info" %} [Learn about the Enhanced Identity Checks API.](/documentation/api-reference/check-types/enhanced-identity-check.md) {% endhint %} ### Analysis performed The Enhanced Identity Check performs multiple layers of **biometric analysis** to validate **active liveness** and **facial similarity.** It also flags **spoofing**, **deepfake**, and **tampering** signals.

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.
### Check duration An Enhanced Identity Check takes an average of **20 seconds** to complete. ### Frequently asked questions
What is an Enhanced Identity Check in KYC? An Enhanced Identity Check is a **high-assurance biometric identity verification** step used in **KYC onboarding**. It compares a **video selfie** to the photo on an official ID document and confirms both **active liveness** and **face match**.
What is video KYC? **Video KYC** is a form of identity verification that uses a **video selfie** to confirm a customer is physically present and matches their identity document. It is commonly used when regulators or risk models require stronger identity assurance than a static selfie.
What is active liveness detection? **Active liveness detection** confirms that the customer is physically present by asking them to complete guided challenges during capture. These can include **motion** and **voice** prompts, which help detect spoofing, replay attacks, and other advanced fraud attempts. ComplyCube is certified to **ISO PAD Level 2**, the highest certification level for this type of liveness check.
Can Enhanced Identity Check detect deepfakes, spoofing, and video replay attacks? Yes. Enhanced Identity Check is designed to detect **deepfakes**, **video replay attacks**, **printed photo attacks**, **3D mask attacks**, and other advanced **liveness fraud** vectors. It uses **ISO-certified PAD Level 2** biometric anti-spoofing controls to reduce fraud risk.
When should I use Enhanced Identity Check instead of Identity Check? Use Enhanced Identity Check when you need **higher-assurance identity verification**, **video-based onboarding**, or guided liveness challenges. Use [Identity Check](/documentation/product-guides/biometric-and-liveness-verification/identity-check.md) when a faster **passive selfie** check is enough for your risk and compliance requirements.
Do I need an ID document and a video selfie for Enhanced Identity Check? Yes. Enhanced Identity Check compares the customer’s **video selfie** against the photo from an official identity document. If you only need document verification, use [Document Check](/documentation/product-guides/identity-verification/document-check.md).
Can Enhanced Identity Check help meet regulated video verification requirements? Yes. Enhanced Identity Check is well suited to jurisdictions and use cases that require **video-based identity verification** or stronger proof of live customer presence.
Can Enhanced Identity Check help prevent account takeover and duplicate accounts? Yes. Enhanced Identity Check helps detect spoofing and can also identify **previously enrolled faces** when enabled, which helps reduce duplicate registrations and related fraud.
Which checks are commonly combined with Enhanced Identity Check in KYC? Enhanced Identity Check is often combined with [Document Check](/documentation/product-guides/identity-verification/document-check.md), [AML Screening Check](/documentation/product-guides/watchlist-pep-and-adverse-media/aml-screening-check.md), [Multi-Bureau Check](/documentation/product-guides/identity-verification/multi-bureau-check.md), and [Proof of Address Check](/documentation/product-guides/kyc-automation-services/proof-of-address-check.md). This helps you move from video liveness and face match verification to a broader KYC and compliance decision in one [Workflow](/documentation/product-guides/compliance-studio/workflows.md).
