Keeping a tamper-evident audit trail

What the rule is

An audit trail is a record of what your AI did and when. It captures the inputs the system received, the outputs it produced, and any time a human stepped in to override a decision.

The record must be tamper-evident and append-only. Once an entry is written, a later change to it is detectable rather than quiet. New entries can be added, and an edit to an old one breaks the hash chain that proves the sequence.

This matters because decisions are often questioned long after they are made. A sealed, tamper-evident trail lets you go back and show exactly what happened: what data went in, what the system decided, and whether a person reviewed it.

Human-override events deserve special care. When someone overturns an automated decision, that moment must be logged. It shows your controls worked and that a human stayed in the loop.

Why it matters

Without a reliable trail, you cannot prove what your AI did. Memory and screenshots are not enough when an inspector asks for the full record.

Under the DIFC Data Protection Law, the DIFC Commissioner has inspection powers. They can ask to see your records for High-Risk Processing. A trail that can be edited after the fact has little value as proof. Where an individual challenges a decision, a clean, tamper-evident trail is your strongest evidence; a weak one can leave you exposed to a private right of action in the DIFC Courts.

How to comply

1. Decide which inputs, outputs, and events you must log.
2. Capture human-override events every time they happen.
3. Store the log in a sealed, tamper-evident, append-only format.
4. Protect the log so an edit or deletion is both restricted and detectable.
5. Keep records long enough to support inspection and review.

How regulation10.ae helps

regulation10.ae records AI inputs, outputs, and human-override events in a tamper-evident, append-only store. That trail is ready to produce as evidence for assessment if the DIFC Commissioner asks. You can show what each system decided, and when a human stepped in, without scrambling for proof.
