Assurance must survive the handoff
A decision may pass from an internal security team to a buyer, a partner, or another reviewer. During that handoff, its scope, conditions, and status can be lost. A portable outcome should carry enough context for the recipient to understand what it represents and how to check its current standing.
Carry the decision’s meaning
The QILAHK approach connects authorized TrustMarks to registry records that communicate the applicable decision and lifecycle status. The outcome should identify the assessed subject, scope, criteria reference, issuing authority, and validity conditions. Protected evidence can remain under agreed access controls while the portable record provides a route to checking the authorized outcome.
A practical example
A supplier presents a TrustMark to a prospective customer. The customer checks the referenced registry record rather than relying on a copied image alone. A current status and matching scope help the customer evaluate whether the assessment is relevant. An expired or suspended outcome requires a different interpretation. Recognition by a particular buyer or integration into another system must still be agreed.
The difference in use
Portability supports consistent communication across organizational boundaries. Cryptographic signatures can help establish integrity and attribution, but they do not independently prove that an assessment was sufficient. The usefulness of the outcome still depends on sound evidence, appropriate criteria, authorized review, and accurate lifecycle information.
