Chain of Custody for Digital Evidence
Boston-based, serving clients nationwide by appointment.
If you’re handling evidence for a legal or insurance matter, chain of custody is the written record that shows what was received, when, from whom, and how it was handled—so the evidence can be trusted later.
Data365 Evidence provides Boston chain-of-custody support and preservation-first evidence handling for legal and insurance-related matters across Greater New England. Forensic data acquisition is performed where appropriate under confirmed engagement terms. Written intake begins with an intake record so source details, access authority, and transfer decisions can be confirmed in writing.
Chain-of-Custody Records and Handling
- Item identification: Record what the item is (device, media, or account export), including serial numbers or identifying labels where available.
- Authorization context: Record the source of authority, engagement limits, and any stated handling constraints.
- Transfer documentation: Record who transferred the item, who received it, the date/time, and condition notes.
- Safeguarding: Store items in a manner that preserves integrity and restricts unauthorized access.
- Time reference: Record dates and times using a consistent system time reference when needed.
- Integrity preservation: Avoid unnecessary change through appropriate handling; document any unavoidable alterations.
- Verification: Apply cryptographic hashes (e.g., SHA-256) to images or exports and confirm consistency when used.
- Recordkeeping: Maintain complete written records suitable for counsel review and later reconstruction of the handling history.
Custody Documentation Overview
- Written intake captured in email: case context, deadlines, and objectives captured in writing.
