Identity-backed digital signing

Digital signatures backed by verified human identity.

FingerSign verifies the signer at the moment of signing, captures intent, and generates tamper-evident proof anyone can validate later.

No certificates. No hardware tokens. No workflow friction.

Biometric identity verified Independent verification No certificate dependency
Proof in motion

Verify - Authorize - Secure

Every signed document carries a transaction-level proof object, not just a visual stamp.

Trusted signing evidence

  • Signer verified at signing time
  • Document integrity checks
  • Immutable evidence records
  • Independent verification via Txn ID / QR
The gap today

Most e-sign workflows verify accounts, not humans.

  • Login or OTP confirms access, not signer presence.
  • Intent capture is often weak or inconsistent.
  • Verification depends on trusting one platform record.
FingerSign shift

Identity to intent to cryptographic proof.

  • SyberKey verifies the signer identity for the act of signing.
  • FingerSign enforces consent/intent and performs document sealing.
  • Evidence is immutable and independently verifiable.
How it works

From upload to verifiable proof in five steps.

FingerSign is web-native and evidence-first: the platform seals documents and preserves an append-only record for validation.

Why FingerSign

Built for proof, not just workflow.

Traditional e-sign tools trust account possession. FingerSign binds verified identity, signer intent, and signed content into one verifiable evidence layer.

Security & legal

Designed for trust, disputes, and regulated workflows.

FingerSign enforces identity checks at signing, records intent signals, protects document integrity, and preserves append-only evidence for independent validation.
