How it works

The simplicity of a selfie, the security of automatic checks.

You take a selfie. Sealfie does the rest — without you having to decide what to verify.

The gesture

Three steps, under two minutes

1. Request

The requester initiates or receives a sensitive request — a wire transfer, a bank-detail change, a decision to approve.

2. Verification

The real requester confirms their identity with a selfie. Sealfie checks the mobile carrier and device fingerprint in parallel.

3. Sealing

The decision is timestamped and sealed into a log — one an auditor, insurer, or court can examine.

What we verify automatically

You don't decide what to check — we do

Unlike solutions that rely on the user's judgment, Sealfie automatically performs these checks in the background:

SIM-swap detection

We query the mobile carrier in real time to detect a recent subscription change or SIM swap.

Device integrity

Hardware-level verification confirms the device hasn't been compromised.

Liveness detection

A multi-layer check confirms the person's real physical presence — not a photo or video.

Why not just MFA or training

Standard MFA and training have documented limits

20% of trained staff still fail anti-phishing tests persistently (Hoxhunt, 2024), and humans fail to detect more than 25% of voice deepfakes even after training (Microsoft, 2024). A CSIRO/SKKU study (2025) tested 16 of the most widely used deepfake detectors on the market: none reliably identified real-world deepfakes. Single-factor MFA has known flaws too — the "AuthQuake" vulnerability allowed bypassing Microsoft's MFA in under 3 minutes (documented in 2024). Sealfie doesn't rely on any single factor: it cross-checks several independent sources at every verification.

Where Sealfie applies

The same gesture protects the order, the meeting and your processes

Sealfie isn't one more app: it's the seal you place wherever a decision matters to the business — a wire order, a decisive meeting (the Attesta use case, inside your video calls), or your own approval process.
