+4.3.4 Evidence Validation

4.3.4 Evidence Validation

Each piece of FAIR or STRONG evidence that is presented SHALL be validated using one of the following techniques:
Confirming the authenticity of the digital evidence by interrogating the digital security features (e.g., signatures on assertions or data)
Confirming the authenticity of the physical evidence using automated scanning technology that can detect physical security features
Confirming the integrity of any physical security features through a visual inspection by a proofing agent using a real-time or asynchronous process (e.g., offline manual review)
Confirming the integrity of any physical security features through physical and tactile inspection by a proofing agent at an on-site location
Each piece of SUPERIOR evidence SHALL be validated through the cryptographic verification of the evidence contents and the issuing source, including digital signature verification and the validation of any trust chain back to a trust anchor. Any piece of SUPERIOR evidence that cannot be validated using this method MAY be considered STRONG evidence if it can be validated by using one of the techniques provided above.
