What is Forged Signatures?

Forged signatures are counterfeits—hand‑written or digital—used to fraudulently approve payments, contracts, or account changes without real consent. Physically, forgers trace or fake handwriting on paper; in digital systems, attackers phish signers, steal keys, or subvert workflows so a “signature” exists but has no legal connection to a person. Audit trails then falsify by omission.

Red flags: pixel‑for‑pixel matching signatures across documents; approval timestamps from unrecognized devices; cert chains with missing or ignored revocation checks; and staff accounts with shortcut privileges. In high‑velocity environments, fraud lurks behind “urgent” processes.

Controls that stick: strong signer identity at enrollment, short‑lived tokens, tamper‑evident logs, and cryptographic timestamps. For sensitive approvals, layer selfie‑to‑ID checks with identity verification and season with liveness checks when risk or value justifies. Separate duty for issuance and approval; rotate keys; and keep revocation easy and fast.

Trust the math, absolutely. But verify the human, too.
