Method — Verify Physical

Definition, scope boundary, and structural model.

Definition

Verify physical describes a structural process for confirming the presence, state, or authenticity of a physical entity through observable or measurable interaction.

It operates at the boundary between digital systems and physical reality, ensuring that physical conditions or entities can be validated independently of internal system claims.

Scope Boundary

Included

Physical presence verification mechanisms
Sensor-based or observation-based validation processes
Interaction-driven confirmation of physical state
Linkage between physical entities and verification outcomes
Cross-system verification of real-world conditions

Excluded

Purely digital or data-only validation processes
Identity verification without physical context
Legal certification or regulatory enforcement
Operational deployment of hardware systems
Vendor-specific sensing or verification technologies

Structural Phase Model

Phase 1 — Observation

A physical entity, condition, or event is observed or detected through interaction or sensing.

Phase 2 — Signal Interpretation

Observed data is interpreted to determine whether it corresponds to the expected physical state.

Phase 3 — Verification Determination

The system determines whether the physical condition satisfies defined verification criteria.

Phase 4 — Validation Output

Verification results are recorded, communicated, or made available for downstream use.
