Digital Asset Claims Data Integrity and Custody
Evidence that cannot be shown to be unchanged is evidence that can be disputed on handling alone. Integrity controls are applied at the moment material enters a case.
Controls Applied At Intake
Hashing on receipt
Every supplied or captured file is hashed on arrival and the value is stored with the item record.
Immutable originals
Originals are held unmodified; analysis is performed on working copies, and derived material is linked back to its original.
Handling record
Access and export events are logged so the movement of an item through the case can be reconstructed afterwards.
Retention And Return
Case material is retained for the period agreed in the engagement and is then deleted or returned, with the action recorded.
Digital Asset Claims does not hold, transfer or move client digital assets at any point; integrity controls apply to records, not to funds.
Limitations
Integrity controls prove that material has not changed since collection. They say nothing about whether the material was accurate when it was created.
