Create the record.
Keep identifying details, photographs and documents in a portable credential package.
The record stays
with the asset.
A physical tag connects people to the asset’s evidence and custody history.
Open the record
from the tag.
The tag identifies the asset’s record and can carry a signed association with its credential. Its printed face can be discreet or carry a miniature artwork.
The record brings its identifying details, photographs and documents together for the next person.
Check the association.
Level 1 checks the signed association between a tag and its credential. Assessment of the physical asset and its attachment uses separate evidence.
- Signed data
- Has the tag envelope’s signed data been altered?
- Signing authority
- Can its signature and delegated authority be verified against an independently trusted key?
- Record association
- Do the credential and evidence reference match the included record?
Evidence that carries forward.
Pass it on.
The recipient reviews and accepts a custody handoff before control of the record moves.
Keep its sources.
Published provenance retains its author, time, category and stated basis for later review.
