Trust by design: 21 CFR Part 11 e-signatures and a tamper-evident audit trail
In regulated quality, a record is only as good as your ability to prove it has not been altered. Here is how electronic signatures and a hash-chained audit trail build that trust into the platform.
By MoniDoseQMS Team
Data integrity is the quiet foundation of regulated quality. An approval only means something if you can prove who gave it and that nothing changed afterwards. FDA 21 CFR Part 11 and the ALCOA+ principles exist to make electronic records as trustworthy as a signed paper one — and MoniDoseQMS is designed to support them.
Electronic signatures that mean something
- Signing requires password re-authentication, so a signature is a deliberate act
- Each signature records the signer, the role, the meaning (authored, reviewed, approved), the timestamp, and the IP address
- Signature workflows can require dual control, with the rules themselves locked in the audit trail
A tamper-evident audit trail
Every uploaded file gets a SHA-256 fingerprint and every action is logged to an application-level, append-only audit trail. Records are chained so that any modification is detectable — you do not just trust that the history is intact, you can demonstrate it. That is the difference between a log and evidence.
ALCOA+ in practice
Good records are Attributable, Legible, Contemporaneous, Original, and Accurate — plus Complete, Consistent, Enduring, and Available. The platform supports these principles: actions are attributed to a user, captured as they happen, and retained for the long term with configurable retention periods.
An audit trail you can prove has not been altered is worth more than a thousand assurances that it has not.
