How UD Identity Document differs from LinkedIn or government IDs
No central database
Your identity record is a cryptographically sealed file. No company holds your data. You share it directly — the recipient verifies it without pinging any server.
Tamper-evident
Every field is SHA-256 hashed at the moment of sealing. If anyone alters a single character — name, qualification, licence number — the hash changes and the document fails verification.
Self-sovereign
You create, hold, and share your identity document yourself. No platform can remove it, revoke access, or monetise your data.
Open format
A .uds file is a JSON file. Any technical person can inspect it. It does not require proprietary software to read or verify.
