What is the purpose of maintaining a chain of custody for documents?

• A. To ensure the integrity and traceability of evidence
• B. To reduce the amount of data
• C. To allow public access
• D. To anonymize all data

Answer: (A)

The purpose of maintaining a chain of custody for documents is to preserve the credibility of those documents as evidence by recording every transfer and handling activity. By noting who had the document, when, where, and for what reason, you create an auditable history that shows the document is the original and has not been altered. This helps prevent tampering, substitutions, or contamination and supports the document’s admissibility in investigations or proceedings.

Reducing data, enabling public access, or anonymizing all data aren’t the goals of the chain of custody. Those functions relate to data management, access rights, or privacy, not the protection of evidentiary integrity.
