Electronic Signatures with Multi-Platform Hardware Root of Trust
Level 5 Security PosturevSign is Veritize's advanced electronic signature platform combining legally-binding signatures with hardware-rooted trust across PC, Apple, Android, and IoT devices — creating the most secure signatures possible.
Most e-signature platforms just record that someone clicked a button. vSign goes further — proving not just THAT you signed, but exactly WHO signed, from WHICH device, using WHAT hardware security chip, at WHAT time, with cryptographic proof anchored to blockchain.
If someone ever claims "I didn't sign that," vSign provides irrefutable hardware-bound evidence that holds up in any court.
Each ecosystem uses a dedicated security processor to handle the Verity Time Seal™ and cryptographic handshakes
Trusted Platform Module — a physical chip (or firmware-based fTPM) on the motherboard. Stores RSA/ECC keys and provides Platform Configuration Registers (PCRs) to prove the OS hasn't been tampered with.
Endorsement Key (EK) against whitelist.
A dedicated RISC processor isolated from the main CPU. Creates permanent, hardware-bound keys via DeviceCheck/App Attest that can only be used by your app on that specific iPhone or Mac.
key_id generated by the Secure Enclave. Prevents cloned or emulated devices from hitting the TSA endpoint.
A discrete hardware element (like Google's Titan M chip) with its own RAM and CPU. Provides hardware-backed key storage and TEE validation — the equivalent of a "PC TPM" inside a smartphone.
STRONGBOX flag in the attestation certificate for maximum security.
Dedicated low-power chips that store the "Golden Master" hash. When a sensor sends data, it's signed by the Secure Element to prove it wasn't intercepted or modified (Man-in-the-Middle protection).
Microchip ATECC608, STSafe, and NXP SE050 for immutable hardware identities.
Every signature receives a Verity Time Seal combining: hardware attestation from the device's security chip, RFC 3161 trusted timestamp, and blockchain anchor — creating an unbreakable chain of cryptographic proof.

Anchored to ledger
Verity Time Seal™
Automatically detects and uses TPM 2.0, Secure Enclave, StrongBox, or Secure Elements based on the signing device's capabilities.
Route documents to multiple signers in sequence or parallel. Track who signed, who's pending, send reminders automatically.
Create reusable templates for contracts, NDAs, onboarding forms. Define signature fields once, use forever.
Combines hardware attestation + RFC 3161 timestamp + blockchain anchor into a single tamper-proof cryptographic seal.
Every view, click, signature recorded with IP, device info, hardware type, and timestamps. Complete forensic evidence.
Desktop, tablet, or mobile — each platform uses its native security chip for maximum protection.
Close deals with instant, legally-binding signatures. Customers sign on their phone (StrongBox), contract anchored to blockchain.
New hire paperwork, policy acknowledgments, benefits enrollment — all with hardware-bound proof of who signed from which device.
Purchase agreements, leases, disclosures — high-value documents with TPM/Secure Enclave attestation.
Patient consent forms, HIPAA authorizations — prove informed consent on a verified device.
Loan docs, wire authorizations — high-stakes signatures requiring absolute proof of signer identity.
Affidavits, declarations, settlements — forensic-grade hardware proof for court.
