Quantum-Seeded Timestamps.
For Legal & Insurance.
Document timestamps, evidence and contract seal values, and unpredictable claim tokens — generated from quantum-seeded entropy.
Overview
Timestamp Fraud
Software-generated timestamps can be backdated or manipulated. Courts are increasingly skeptical of digital timestamps without cryptographic proof.
Evidence Tampering
Digital evidence without a verifiable chain of custody is open to dispute. Without tamper-evident seals, evidence integrity is questionable.
Insurance Fraud
Claim tokens built on weak randomness can be forged, replayed, or predicted. Unpredictable, signed claim tokens make forgery and replay detectable.
"backend": "quantum_seeded" to use QuantumRand's generator seeded from real IBM Quantum hardware, or "ibm_hardware" for a direct hardware run. Every response is labelled with the source that produced it, and if the chosen backend is unavailable the call fails rather than quietly switching source.Document Timestamp
Quantum-timestamp any document with an HMAC-SHA256 signature. Returns a timestamp and an HMAC value for the document hash. The value cannot be re-verified yet (see the limitation above).
Evidence Seal
Quantum-seal digital evidence with a tamper-evident chain-of-custody signature. Returns a timestamped seal value; it cannot be re-verified yet.
Contract Signing
Quantum-sign a contract hash with all signatories recorded. Returns a timestamped seal value for the signing event; it cannot be re-verified yet.
Insurance Claim Token
Quantum-signed claim tokens with 72-hour TTL. Each token is cryptographically bound to the claim, policy, and claimant — unpredictable, with a 72-hour lifetime.
Document Seal (not a legal notary)
Quantum-notarize any document hash with a cryptographic certificate. Returns a timestamped seal value for the document hash; it is not a notarization and cannot be re-verified yet. The quantum certificate ties the document to a specific moment in time using entropy that is hard to predict or replicate.
Quantum Timestamps
A signed record of when a document's hash was sealed. Re-verification is not available yet.
Chain of Custody
Every evidence seal logged, timestamped, and signed with quantum-seeded cryptography. Full chain-of-custody documentation exportable on demand.
Fraud Prevention
Quantum claim tokens resist forgery and replay. 256-bit quantum entropy makes brute-force attacks computationally infeasible.
Audit Export
Full audit trail exportable to CSV for court proceedings, arbitration, or regulatory review. Every operation is timestamped in your usage log.
/generate API and any call made with "backend": "quantum_seeded". Until the first hardware seed arrives after a restart, those bits come from the OS CSPRNG and the source label says so.Contract Management
Quantum-signed contracts with full signatory audit trails. Record when a contract was sealed.
Digital Evidence
Tamper-evident evidence seals with chain-of-custody tracking. Timestamped seal values (not yet re-verifiable).
Insurance Claims
Quantum claim tokens with 72-hour TTL and replay prevention. Unpredictable tokens make guessing and replay harder.
Real Estate Closings
Signed, timestamped closing documents. Seal values are not yet re-verifiable.
IP Protection
Quantum timestamps for patent filings, trade secrets, and creative works. Keep a timestamp record alongside your own evidence of prior art.
Regulatory Filings
Quantum-sealed regulatory submissions with tamper-evident audit trails. Record when a submission was sealed.
