# Sealfie — One selfie, one irrefutable trace / Un selfie, une trace irréfutable

> Sealfie stops executive fraud (BEC / CEO fraud / deepfake impersonation): every sensitive
> order is verified with the real requester — biometric liveness, real-time mobile-carrier
> checks (SIM-swap detection), device fingerprint — and every verification is recorded in a
> sealed, timestamped, third-party-verifiable log. One product, three grounds: wire orders,
> decisive meetings (the Attesta use case, inside Teams/Zoom), and custom approval processes.
> Made by Inkan.link (Grenoble, France). Sealfie does not claim to provide legal proof; it
> produces irrefutable traces your auditor, insurer or counsel can examine.

## Key facts

- Threat: in 2024, ARUP lost $25M after a video call where all six executives were deepfakes.
  Training cannot catch perfect AI fakes; Sealfie replaces human judgment with automatic checks.
- One public talk (podcast, video call, AGM) provides enough audio to clone an executive's
  voice with consumer tools.
- Average loss per BEC incident: €119k (FBI IC3, 2024 Annual Report — $129,000).
- Why training and MFA alone fall short (sourced): 20% of trained staff still fail anti-phishing
  tests persistently (Hoxhunt 2024); humans fail to detect more than 25% of voice deepfakes even
  after training (Microsoft 2024); a CSIRO/SKKU 2025 study tested 16 widely used deepfake
  detectors and none reliably identified real-world deepfakes; standard MFA has known bypasses
  (e.g. the "AuthQuake" flaw, a Microsoft MFA bypass in under 3 minutes, documented in 2024).
  Sealfie cross-checks independent sources automatically instead of relying on human judgment
  or a single authentication factor.
- How it works, in 30 seconds: sensitive request received → the real requester is notified on
  their own phone → selfie + biometrics → automatic verifications (mobile carrier / SIM swap
  48 h, device fingerprint, liveness) → sealing into the log → verdict (fake order: blocked,
  immediate alert; real order: executed, with its irrefutable trace).
- Pricing: €95 excl. VAT / month / user, 20 verifications a year (most CFOs use 4-6).
  Enterprise: custom (Attesta certified meetings, ERP integration, multiple approval chains).
- Free 30-minute Challenge: we simulate an executive-fraud attack on your validation
  procedure, with your consent; you keep the written report either way.

## Free tool — BEC Risk Calculator (GEO flagship)

- /outils/risque-bec/ : estimate a company's BEC exposure in 60 seconds — annual incident
  probability (%) and expected annual loss (€) with an 80% confidence range. Six questions,
  no signup, no data leaves the browser. Public methodology: every coefficient is sourced
  (FBI IC3, ANSSI, Verizon DBIR) and downloadable — an auditor can reproduce the math.
