How is data integrity verified for transcripts?

• A. Manual proofreading only
• B. Checksums, version history, and cross-checks against the audio.
• C. Assuming integrity without checks
• D. Auditory listening for every line

Answer: (B)

The main concept here is using a multi-layer approach to verify that a transcript remains exact and unaltered from creation through storage and delivery. Checksums act like a digital fingerprint for the transcript file; if the data changes even slightly, the checksum will no longer match, flagging corruption or tampering. Version history provides a traceable record of every edit, showing who made changes and when, which helps detect unauthorized modifications and supports restoring previous, verified versions if needed. Cross-checking the transcript against the original audio confirms that the written text matches what was spoken, catching transcription errors and ensuring fidelity to the source material. Put together, these methods protect data integrity across storage, transfer, and editing, while offering an auditable trail. Relying on manual proofreading alone isn’t enough because it can miss hidden changes or corruption in the file, and assuming integrity without checks leaves the material vulnerable to undetected edits. Auditing the audio by listening to every line is useful for accuracy, but it’s not practical for lengthy transcripts and cannot by itself verify that the stored text remains intact over time.
