Fused Identity
Fused Identity. One Verification.
Multiple identity factors — person, document, device, location — fused simultaneously on one device into a single tamper-proof verification. Not sequential checks. Simultaneous fusion.
The Fusion Gap
Most verification products check identity factors one at a time — face first, then document, then device. Each check happens separately, often on different systems, at different times. The gaps between checks are the gaps attackers exploit.
Fused identity eliminates those gaps. All factors are verified simultaneously, on one device, in one cryptographic operation. There is no window between checks for an attacker to intervene.
How Fusion Works
The results from each verification factor are cryptographically bound together into a single signed token. The token proves that all factors were verified simultaneously — not that they were verified at some point individually.
All Factors Captured Simultaneously
Polyguard Mobile captures person (facial recognition), document (NFC chip read), device (hardware attestation), and location (PG-Presence + geolocation) in a single session on one device.
Cryptographic Binding
The results from each verification factor are cryptographically bound together into a single signed token. The token proves that all factors were verified simultaneously — not that they were verified at some point individually.
Verification Result Delivered
The signed verification token is delivered to the requesting application. It contains the verification result, confidence scores, and attestation data. No raw biometric data is included.
Available Factors
Polyguard Mobile captures person (facial recognition), document (NFC chip read), device (hardware attestation), and location (PG-Presence + geolocation) in a single session on one device.
Person
Real-time facial recognition with 3D depth analysis. Confirms the person in front of the camera matches their enrolled identity. On-device processing — no facial data leaves the phone.
Document
Government-issued identity documents verified through NFC cryptographic chip reading. Not OCR, not a photo of a document — a direct read of the document's embedded chip, verified against the issuing authority's digital signature.
Device
Hardware-backed device attestation via Apple AppAttest (iOS) and Google Play Integrity (Android). Confirms the verification is running on a genuine, unmodified device — not an emulator, not a rooted phone, not a virtual machine.
Location
Geolocation data from the device, combined with PG-Presence optical distance bounding to confirm the person is physically at the device during verification.
Phone Number
Phone number ownership confirmed via SIM binding and carrier verification. Provides an additional factor linking the verification to a specific mobile account.
Additional factors can be added as verification requirements evolve.
Why Fusion Matters
Deepfakes Fail Against Fusion
A deepfake can fool a camera. It cannot simultaneously present a real face, a genuine government ID via NFC, a hardware-attested device, and physical proximity confirmed by optical distance bounding.
Stolen IDs Are Not Enough
A stolen document can pass a document check. But the person holding it cannot pass facial recognition matched against the document's enrolled biometric data, on a device bound to the real owner.
Remote Attacks Are Closed
PG-Presence confirms the person is physically at the device. Remote desktop, screen sharing, and KVM attacks — which present a real face to the camera from a different location — are detected and blocked.
Identity Persistence
Once identity is established through fusion, subsequent Trust Checks take seconds. The device is bound to the identity. Re-verification is fast, seamless, and just as secure — because the cryptographic anchor remains.
First Verification
User completes a full Trust Check — facial recognition, document, device, location. Identity is established and anchored to the device.
Subsequent Trust Checks
Each new interaction re-verifies the person against their established identity. Seconds, not minutes. No document re-scan needed.
Continuous Confidence
Every verification is logged with a Transaction Affidavit. The identity record becomes stronger with each interaction — a chain of verified events.
