IUSign vs Audit Integrity
for Cryptographic Proof
Don't just trust a log file. IUSign gives you a SHA-256 hash chain you can verify independently, proving document history is immutable.
Why IUSign is Different
Cryptographic Proof
SHA-256 hash chain where each entry includes the hash of the previous one; DB-level triggers block all modifications to logs.
Integrity Verification
Independent SHA-256 hash chain
Modification Protection
Hardware-level DB triggers block edits
Sequence Proof
Cryptographic back-link to prev entry
Forensic Triggers
Automatic alerts on tampering
Audit Integrity Approach
Standard logs are simple database entries that admins can modify or delete; trust is centralized in the vendor.
- Download audit log as PDF
- Rely on vendor's timestamp
- Hope the database wasn't tampered with
- No way to mathematically prove sequence
IUSign Approach
SHA-256 hash chain where each entry includes the hash of the previous one.
- Download log + cryptographic chain proof
- Verify each hash links to the previous
- Proof that log is immutable and sequential
- Mathematical certainty of event timing
Result
Cryptographic proof is irrefutable, making your documents more legally defensible.
Head-to-Head Comparison
Why IUSign is the preferred choice for enterprise scalability.
| Feature | IUSign | Audit Integrity |
|---|---|---|
| Integrity Verification | ✅ Independent SHA-256 hash chain | ⚠️ Vendor-provided logs |
| Modification Protection | ✅ Hardware-level DB triggers block edits | ❌ Admin can edit logs |
| Sequence Proof | ✅ Cryptographic back-link to prev entry | ❌ Time-based only |
| Forensic Triggers | ✅ Automatic alerts on tampering | ❌ Not available |
Frequently Asked Questions
How do I verify the hash chain myself?
We provide an open-source verification script. You download your audit logs via API and run the script locally to confirm that every hash matches the sequence, proving nothing was deleted or inserted.
Can't your developers modify the hashes?
No. The hashes are generated and locked by the database engine itself using triggers that cannot be disabled without wiping the entire table, which would be immediately detected by our sentinel.
