Data integrity and tamper-proof weighing records

A weighing record can decide a payment, a penalty or a dispute. Its value depends on everyone trusting that it has not been altered.

Capture without retyping

Read weights directly from the indicator and plates from ANPR, with time from a synchronised clock.

Make records append-only

Never update a weighing in place. Corrections create new entries that reference the original, with the operator and reason recorded.

Attribute every action

Each operator signs in individually. Shared logins make it impossible to know who did what.

Detect tampering

• Store a cryptographic hash of each record, chained to the previous one, so any later change is detectable.
• Replicate records to a central server promptly so local changes can be compared.
• Log configuration changes such as limits and calibration values.

Keep the evidence

Store images alongside records and keep backups off site.

Audit regularly

Supervisors should review voided transactions, manual overrides and unusual operator activity.
