Verification & Audit Trails

Filedgr transforms every file, record, or data stream into cryptographic proof, ensuring verifiable integrity and a tamper-proof audit trail for compliance and trust.

Automatic Verification​

Every upload or data update is instantly verified through a secure, multi-step process to ensure authenticity.

Verification Process​

  1. File Integrity Check - Ensure file wasn't corrupted during upload
  2. Cryptographic Hashing - Generate unique fingerprint (SHA-256)
  3. Blockchain Anchoring - Record hash on blockchain with timestamp
  4. IPFS Distribution - Store encrypted data across decentralized nodes (see Decentralized Storage in Security & Compliance)
  5. Verification Certificate - Generate downloadable proof document

What Gets Verified​

Filedgr verifies a wide range of data types and actions to maintain a complete record of authenticity.

  • Static files uploaded to vaults
  • Data imported from external systems via API
  • Physical assets connected through identifiers (QR codes, NFC tags)
  • Continuous data streams from IoT sensors or financial feeds
  • User actions and permission changes

Verification Results​

Each verification provides clear, shareable evidence of data integrity.

  • Blockchain transaction ID - Immutable record reference
  • IPFS hash - Content-addressed storage reference
  • Timestamp - Exact time of verification
  • Certificate - Downloadable verification document
  • Shareable link - Public verification URL

Audit Trails​

Filedgr maintains a tamper-proof history of all actions for compliance, security, and dispute resolution.

What's Tracked​

  • File uploads - Who uploaded what and when
  • Data modifications - All changes with before/after states
  • Access events - Who viewed or downloaded files
  • Permission changes - Access grants/revocations
  • System events - Automated actions and integrations

Audit Log Details​

Each audit entry includes:

  • User identification - Who performed the action
  • Precise timestamp - When the action occurred
  • Action type - What was done (upload, modify, access, etc.)
  • Resource affected - Which vault/file was involved
  • Change details - Specific modifications made
  • IP address - Where the action originated
  • Device information - Browser/app used

Audit Trail Benefits​

  • Compliance ready - Meet regulatory requirements automatically
  • Dispute resolution - Clear evidence for resolving conflicts
  • Security monitoring - Detect unauthorized access attempts
  • Process optimization - Understand usage patterns

Timestamping​

Blockchain-based timestamping provides undeniable proof of when a document or dataset existed in a specific state.

Timestamp Accuracy​

  • Blockchain consensus - Multiple network nodes confirm timestamp
  • Atomic operations - Timestamp recorded simultaneously with data
  • Immutable records - Cannot be altered retroactively
  • Global synchronization - Consistent across all time zones

Regulatory Applications​

  • GDPR compliance - Prove when data was collected/processed
  • CSRD reporting - Timestamp sustainability data
  • MiCA requirements - Financial transaction timing
  • HIPAA audits - Medical record creation/modification times
  • Legal evidence - Establish document existence for litigation

Multi-Chain Resilience​

Verification records can be anchored across multiple blockchains for reliability and future-proofing.

  • Multiple blockchains - Anchor across different networks
  • Network redundancy - Continue operating if one chain fails
  • Cross-verification - Compare timestamps across chains
  • Future-proof - Resistant to individual blockchain changes

Verification Types​

Filedgr supports multiple verification methods tailored to different use cases.

Document Verification​

Static file verification with cryptographic proof:

Original File → SHA-256 Hash → Blockchain Record → IPFS Storage

Use Cases:

  • Legal contracts and agreements
  • Quality certificates and compliance documents
  • Financial reports and statements
  • Medical records and test results

Data Stream Verification​

Real-time data verification with continuous monitoring:

Data Point → Validation → Hash → Blockchain → Alert (if anomaly)

Use Cases:

  • IoT sensor readings
  • Financial transaction data
  • Supply chain tracking information
  • Manufacturing process metrics

Event Verification​

Discrete event recording with contextual information:

Event Trigger → Event Data → Metadata → Blockchain Record → Notification

Use Cases:

  • Asset transfers and ownership changes
  • Maintenance activities and inspections
  • Regulatory compliance milestones
  • Business process completions

Third-Party Verification​

Enable independent verification without exposing sensitive data, using shareable links or APIs.

Generate shareable proof links:

  • Public verification - Anyone can verify no changes have been made to the data without an account
  • No data exposure - Proves integrity without revealing content
  • QR codes - Easy mobile verification
  • Embeddable proofs - Add to websites or documents

API Verification​

Allow systems to verify data programmatically:

curl -X GET "https://verify.filedgr.io/api/verify/vault_abc123" \
  -H "Accept: application/json"

Response:

{
  "verified": true,
  "vaultId": "vault_abc123",
  "createdAt": "2024-01-15T10:30:00Z",
  "blockchainTx": "0x1234...",
  "fileCount": 15,
  "lastModified": "2024-01-20T14:22:00Z"
}

  timestamp: new Date().toISOString()
});

// Automatically generate quality certificate
if (qcResult.passed) {
  await generateQualityCertificate(productBatch, verification);
}

Financial Reporting​

Verify financial data for regulatory compliance:
