Face API — High‑Precision Biometric Verification for Identity Matching

Industry‑validated accuracy, low latency, and robust security to onboard users faster and cut manual reviews.

Make onboarding quicker for users

Instantly verify user identities with high-precision biometric matching, providing a seamless onboarding experience and minimizing friction.

Liveness & Deepfake Protection

Enhance your platform’s security with built-in liveness and deepfake detection—advanced safeguards that minimize fraud, verify real users, and build trust at every step.

Reliable Speed at Any Scale

Our stable algorithm delivers reliable performance and fast verification for platforms of any size, supporting seamless growth as your user base expands.

Biometric Matching Methods

OOTO’s Face API offers two flexible facial recognition modes to meet your specific identity verification needs

1:1 (One-to-One) Matching

Verify whether two face images belong to the same person — in real time, without any database. This method is ideal for quick, privacy-preserving identity checks like selfie-to-document matching or user-to-user verification.

HOW IT WORKS

Upload two images (e.g., a selfie and an ID photo). The API calculates similarity based on deep facial embeddings.

KYC onboarding

fraud detection

duplicate prevention

1:N Face Identification (One-to-Many)

Identify a person by comparing their face to your own database of enrolled users. First, enroll images via API — each face is stored as an anonymized, non-reversible vector in your secure workspace.

HOW IT WORKS

Upload a single photo. The system finds the closest match from your stored templates (up to 500,000+ users).

access control

watchlist checks

returning user identification

We do not collect any personally identifiable biometric data. Only anonymized facial features are processed and temporarily used for matching.

How Face API Works

Upload a face photo

Start with a photo — from file or other source.

Biometric feature extraction

Our system analyzes the image and converts the face into a mathematical feature vector.

Matching process

The system extracts facial features from the input image and compares them to your stored templates. It returns similarity scores, allowing you to determine whether there’s a confident match — or not.

Receive results

Get an instant match result in two formats:

Structured JSON — includes template ID, similarity score, liveness, face quality, demographics, and pose.
Visual table view — a compact summary with key indicators for quick decision-making.

Optional Liveness & Deepfake check

Add a layer of fraud protection by confirming the user is real and not spoofed.

Upload Two Face Photos

Send two images for instant comparison.

Biometric Feature Extraction

Our system analyzes the image and converts the face into a mathematical feature vector.

Matching proccess

The two extracted vectors are compared in real time to calculate a similarity score — measuring how closely the faces match.

Receive results

Get an instant match result in two formats:

Similarity score between the two faces
Landmarks, liveness, and image quality for both images

You’ll also get a table view with key indicators — for a quick visual assessment of the match result.

Optional Liveness & Deepfake check

Add a layer of fraud protection by confirming the user is real and not spoofed.
