Which element is essential to ensure data integrity during investigative reporting?

• A. Publish all data publicly.
• B. Delete source identifiers.
• C. Use only internal data.
• D. Document chain of custody.

Answer: (D)

Maintaining a documented trail of how data is handled is essential for data integrity in investigative reporting. This means recording every transfer, handling step, and processing action from collection to final use, including who worked with the data and when. That trace creates a verifiable history showing the data hasn’t been altered or misrepresented, which is crucial for trust, accuracy, and the ability to reproduce findings. If data are published publicly without proper controls, sensitive sources can be exposed and the integrity of the data may be questioned. Deleting source identifiers breaks the link to the original information, making verification impossible. Relying only on internal data can introduce bias and omit important external verification. By documenting the chain of custody, reporters establish accountability and a solid, checkable record that supports the reliability of the investigation.
