Which practice helps prevent errors when handling digital evidence?

• A. Delete metadata to simplify.
• B. Modify timestamps to fit a narrative.
• C. Share raw data with unauthorized personnel.
• D. Copy evidence, verify integrity, and document handling.

Answer: (D)

Preserving evidence integrity and maintaining a clear chain of custody are essential when handling digital evidence to prevent errors. The best practice is to make a forensic copy of the evidence, verify its integrity with a hash or checksum, and meticulously document every action taken—who handled it, when, and what was done. This creates an auditable trail, ensures the original remains unaltered, and helps confirm that the evidence presented is a faithful, unmodified version of what was seized.

Deleting metadata can strip important provenance and context, potentially obscuring how or when the data was created or modified. Modifying timestamps can misrepresent the sequence of events, compromising credibility. Sharing raw data with unauthorized personnel breaches security and can contaminate the evidence.
