Post-Preservation Verification, Transfer, and Delivery

Preserved materials proceed through verification, documentation, transfer, and delivery under recorded handling procedures.

Preservation Deliverables

Preserved Materials

  • Authorized mailbox, cloud-repository, and account exports
  • Forensic images within approved scope
  • Structured file collections with associated metadata

Preservation Records

  • Authorization record and confirmed source inventory
  • Acquisition log and handling record
  • Custody and transfer record
  • Verification records, including hash values when generated

Post-Preservation Controls

Handling Continuity

  • Controlled and traceable storage
  • Access limited to authorized parties
  • Transfer records identifying the item, transferring party, recipient, date, time, and purpose

Transfer Package

  • Material labels aligned with the preservation records
  • Cover sheet identifying contents and approved scope
  • No interpretive findings or conclusions within the preservation records

Secure transfer and controlled delivery

Transfer method is determined by approved scope, material sensitivity, recipient authority, and delivery requirements.

  • Packaging and labeling aligned with the preservation records
  • Transfer records identifying recipient authority, date, time, and purpose
  • Encrypted delivery or encrypted media where required
  • Controlled storage pending delivery

Verification and Integrity Records

Hash Verification

Where hashing is available, recorded hash values support later validation that the preserved file set, export, or forensic image remains unchanged.

  • Hash values recorded at acquisition and at later verification points where required
  • Identification of the file set, export, or forensic image covered by each value
  • Verification method available to authorized downstream reviewers

Preservation Record Completeness

  • Scope and authorization references
  • Source identifiers and acquisition method
  • Errors, exceptions, and material limitations
  • Custody, transfer, storage, and delivery records

Separation of Preservation and Analysis

Preservation encompasses authorized acquisition, verification, and records tied to the approved sources. Substantive interpretation, event reconstruction, attribution, and legal conclusions remain outside Data365’s services and may be addressed by a separately retained outside expert.

Post-Preservation Control Failures

Uncontrolled Duplication

Uncontrolled copying obscures source and copy status and interrupts traceability.

Incomplete Transfer Records

Missing recipient, authorization, date, time, purpose, or delivery information interrupts custody continuity.

Scope Expansion

Interpretive conclusions and investigative opinions exceed Data365’s service scope and may be addressed by a separately retained outside expert.

Uncontrolled Storage

Unencrypted media, shared folders, or undefined access rights create confidentiality and integrity risk.
