Not File Storage.
Evidence Storage.
ProntoVault uses cryptographic signatures to bind documents to verified human identities. Get mathematical proof of consent, tamper-proof storage, and zero-knowledge verification—solving the "weak link" of repudiation in content creation and compliance.
The Repudiation Problem
Traditional document storage creates legal vulnerability.
The Old Way
- ✗ "I have a PDF release form" — Can be faked or edited
- ✗ "They signed it" — Can be denied later
- ✗ "I have their email consent" — Email headers can be spoofed
- ✗ "The document is on my Google Drive" — No proof of integrity
Result: Your "proof" becomes worthless the moment someone claims forgery or altered documents.
The ProntoVault Way
- ✓ Cryptographic hash proves document integrity
- ✓ Digital signature bound to verified ProntoID
- ✓ Immutable ledger with timestamp and IP tracking
- ✓ Mathematical proof of consent and chain of custody
Hash(Document) + Signature(Identity) + Timestamp = Proof
If a single pixel in a scanned ID or a single comma in a contract changes, the hash changes completely. ProntoVault gives you mathematical certainty 10 years from now that this is the exact document that was signed.
The Cryptographic Handshake
Every upload becomes an active security event.
Upload
Creator uploads document to ProntoVault and tags the recipient's ProntoID.
Hash
SHA-256 hash calculated client-side. Digital fingerprint created before file leaves your device.
Quarantine
Document held in "Pending" state. Recipient notified to review and sign.
Sign
Recipient's ProntoID cryptographically signs the hash, creating non-repudiation.
Lock
File moved to immutable vault. Full audit trail with IP, device, time, and identity logged.
Cryptographic Receipt Confirmation
Unlike traditional file sharing where you hope someone received your document, ProntoVault requires the recipient to cryptographically sign a receipt. This creates an immutable record that Identity X received Document Y at Time Z—and they acknowledged its contents with their verified digital signature.
The "Most Secure Strategy" Architecture
Every document is treated as a digital asset that must be sealed.
Digital Fingerprint
SHA-256 cryptographic hash generated for every document. Change a single byte and the hash changes completely.
Benefit: Guarantees integrity. Prove 10 years from now this is the exact file that was signed.
Identity Signing
Recipients use their ProntoID private key to sign the document hash, creating a permanent chain of custody.
Benefit: Non-repudiation. Mathematical proof of who signed what and when.
Cold Storage Vault
AES-256 encryption at rest with WORM (Write Once, Read Many) compliance. Files are immutable once committed.
Benefit: Even with physical server theft, data remains encrypted and unreadable.
Key Management: Rotating encryption keys managed by separate KMS (Key Management System)
Enterprise-Grade Features
Built for compliance, security, and legal defensibility.
Cryptographic Binding
Permanent link between verified identity and document hash. Even if a model deletes their account, the audit trail remains.
The cryptographic proof that "User X signed Document Y on Date Z" is mathematical and independent of current account status.
Zero-Knowledge Verification
Verify compliance without exposing sensitive PII. Generate verification tokens instead of sharing full documents.
Example: "Confirmed. Valid Model Release exists for Identity #12345. Expiry: 2026. Signature Valid." ✓
Visual Trust Anchor
Downloaded PDFs include stamped QR code and Hash ID in the footer. Scan to verify authenticity.
Scanning the QR takes viewers back to vault.prontoid.com to verify the document hasn't been photoshopped or altered.
Immutable Audit Trail
Complete chain of custody with IP addresses, device IDs, timestamps, and identity verification for all parties.
Once a file is committed to the Vault, it's immutable. It cannot be edited—only superseded by a new upload with a fresh audit trail.

Integration Example: Telehealth Platform
HIPAA-compliant patient consent without exposing sensitive medical records.
❌ The Problem
A telehealth platform needs to verify that patients signed HIPAA consent forms before specialist consultations. Traditional approach requires sharing full medical records with Social Security numbers and home addresses across multiple providers.
✓ The Solution
Patient's primary care physician uploads consent form to ProntoVault. Specialist receives verification token showing consent is valid and cryptographically signed—without seeing SSN, address, or other protected health information.
Zero-Knowledge Verification Response
Result: Specialist confirms patient consent and identity verification without accessing Protected Health Information (PHI), maintaining HIPAA compliance while enabling seamless care coordination.
