SealfieFrequently asked questions
On how it works, security, pricing, and getting started.
Sealfie stops deepfake fraud and executive impersonation by verifying the real requester's identity with a selfie. When someone requests a wire transfer or sensitive action, Sealfie confirms it's really that person, not a criminal using a deepfake or stolen credentials. In 2024, ARUP lost $25M after a video call where every other participant was a deepfake.
When you receive a sensitive request (wire transfer, credential change, decision), you ask the person to verify with Sealfie. They take a selfie, and Sealfie confirms their identity while checking, in parallel, the mobile carrier (SIM-swap detection), device fingerprint and the physical presence of the real person. The result is sealed into a timestamped log.
During your verifications, your biometrics never leave your phone: the fingerprint or face recognition is processed by your operating system, inside the device's secure element (Secure Enclave on iPhone, StrongBox/TEE on Android). It only authorises the use of a cryptographic key that stays confined to that element. For these verifications, we never receive, process or store any biometric data. The selfie is kept as a timestamped visual record, with no template extracted and no facial recognition by Sealfie. At account creation, ShareID, a processor of Inkan.link, processes a video or photo of your face for facial recognition; ShareID states that it does not retain biometric data. Subprocessors are detailed in our privacy policy.
Sealfie is an annual subscription per user, with 30 simple validations per year per user, pooled across the company. Contact us at contact@inkan.link to get pricing; MSPs and resellers get partner pricing the same way. Beyond that, a custom-quote Enterprise plan exists, as it does for multiple approval chains and Attesta (video-call verification).

Email support@sealf.ie to suspend the verification tied to your device. On a new phone, or if the biometrics on the phone change, you go through onboarding again (re-onboarding) under supervision. Recovery is handled as a priority by the team.
No, only executives and high-risk people (CFO, treasury, decision-makers) need Sealfie. Sizing depends on your actual org chart, not a generic package.
No, it complements it differently: training aims for humans to spot fraud, Sealfie verifies automatically without depending on human judgment, which matters against deepfakes designed to fool trained professionals.
Because listeners identified only 73% of speech deepfakes: more than a quarter get through, and showing examples adds only 3.8 points on average (UCL, PLOS ONE, August 2023). Tools fare no better: a CSIRO / Sungkyunkwan 2025 study benchmarked 16 reference detectors and none reliably identified real-world deepfakes. Sealfie doesn't ask anyone to spot anything by eye: verification is automatic, before the question even arises.
Standard MFA relies on methods that can be bypassed: SMS codes intercepted via SIM-swap, push notifications approved through fatigue, or known flaws like AuthQuake (a Microsoft MFA bypass in about an hour with no user interaction, fixed by Microsoft in October 2024). Sealfie cross-checks several independent sources at every verification (biometrics, mobile carrier, device fingerprint) instead of relying on a single factor.
