Importance of Immutable Audit Trails
The Anatomy of a Legal Signature
A signature is more than a PNG image. It is the context of the signature—IP address, device info, timestamps, and intent—that makes it legally defensible in court.
Cryptographic Tamper-Evidence
We use SHA-256 hash chaining to ensure that every event in a document's history is immutably linked to the next. Any attempt to modify even a single byte of the audit log will break the cryptographic chain.
Exporting Evidence Packages
When compliance calls, you don't need a developer. IUSign allows one-click exports of full JSON evidence packages containing all metadata required for legal proceedings.
Take the next step towards document sovereignty.
