Section 85 of 105
82. Physical-to-Digital Identity Binding
Stable section ID: S05-CON-014-SECTION-85 · 27 content blocks
Every Digital Identity shall be verifiably bound to the physical asset it represents.
The binding method shall be proportionate to the asset’s criticality and may include:
- Durable human-readable marking.
- QR or matrix codes.
- RFID or NFC.
- Laser engraving.
- Embedded identification devices.
- Tamper-evident features.
- Manufacturing records.
- Physical characteristics.
- Cryptographic credentials.
- Installation and inspection evidence.
Identity verification shall establish that the physical asset, digital record, product version, and declared configuration refer to the same Engineering Asset.
The binding shall be checked at relevant lifecycle events, including:
- Product release.
- Receipt and logistics transfer.
- Installation.
- Commissioning.
- Inspection.
- Repair.
- Replacement.
- Reuse.
- Requalification.
- Retirement.
A digital record shall not override contradictory physical evidence. Where the identity of an installed asset cannot be verified, the affected asset and dependent configuration shall remain unknown, restricted, isolated, or inspection-required.
Loss or damage of a physical marking shall not automatically destroy the Digital Identity. Rebinding may occur through an authorized process using sufficient evidence, independent verification where required, and preservation of the original identity history.
Unauthorized relabeling, duplication, substitution, or reassignment of identity shall constitute a serious System05 nonconformity.
