Security & Trust
We would rather state exactly what the current evidence supports than imply more than we can prove.
Evidence register
Each statement carries its own scope. A qualified claim is not a weaker label; it is the boundary that keeps the statement accurate.
Verified
Implemented audit events, work-order transitions and review records retain the account and timestamp associated with the action.
Scope: Scoped to implemented events and actor fields on core records.
Verified
Access is scoped by organisation and implemented role. Database row-level security enforces those boundaries rather than relying on interface labels alone.
Scope: Verified roles include Widian administrators, surveyors, suppliers and client users.
Qualified
SHA-256 hashes support integrity checking for inspections, evidence photographs, signatures, work orders and issued reports.
Scope: Hashing is not external notarisation, legal chain-of-custody certification or a claim that every record is tamper-proof.
Verified · issued reports only
Once a report is issued, its original bytes, hash and template version are frozen. It cannot be deleted and can only move one way to superseded or withdrawn.
Scope: This control applies to issued reports, not every record in Widian.
Limits kept visible
Integrity checking
Widian calculates a SHA-256 digest from the relevant digital content. That digest acts like a content fingerprint: if the content changes, calculating it again produces a different result.
A SHA-256 digest is calculated for supported evidence and record types.
The digest remains associated with the content it was calculated from.
A later calculation can be compared with the retained digest to detect a mismatch.
This can show that checked content no longer matches its retained digest. It does not by itself prove when or why a change occurred, who was responsible, that the original content was accurate, or that every Widian record is legally immutable. It is not external notarisation or chain-of-custody certification.
Current scope: inspections, evidence photographs, signatures, work orders and issued reports.
