ID Analysis
What does this identity document say? Extracts the data from the front and the back, identifies the document type, crops the face, and validates consistency between sides and sources.Front and back, with cross-validations.
Face Analysis
Is it the same person? Compares the selfie against the document photo — or a stored vector — and scores capture quality, pose, and facial attributes.A 0–100 score for every pair of faces.
Facial Antispoofing
Did this selfie come from a real person in front of the camera? Detects photocopies, screenshots, deepfakes, and chromatic tampering.One HTTP call, one verdict.
Connection Fingerprint
Who is on the other end of the connection? Identifies the device by its TLS signature, its headers, and its geographic origin.No SDK, no tracking JavaScript.
Which one you need
How they differ
The underlying difference is who sets the threshold: Facial Antispoofing decides (
spoofing is a verdict), ID Analysis and Face Analysis return data and scores over which your policy defines what to accept, and Connection Fingerprint informs — inputs for your own risk engine.How they combine
In a real onboarding, all four contribute at different moments of the same session: the document is read first, the document face is compared against the selfie, and the selfie goes through liveness.1
The fingerprint arrives first
You get it when the session opens, before asking the user for anything. If the client already looks automated, you can harden the flow or stop it without spending a biometric check.
2
The document is read and validated
ID Analysis extracts the data from the front and the back, validates that both sides belong to the same document, and returns the cropped face.
3
The selfie is compared and checked for liveness
Facial Antispoofing confirms the selfie came from a present person; Face Analysis compares it against the document face:
biometric["0"]["1"] >= 70.4
The final decision is yours
The antispoofing verdict and the biometric score authorize approval; the fingerprint and the document validations tell you with how much confidence, and whether an extra factor is worth asking for.
