Dear Sir/Madam,

This is a request for records under the Freedom of Information Act (2000). I am requesting the record about document redaction in detail. In particular, I ask for:

1. Please describe the process and standards used by your organization to redact documents. Specifically, what guidelines, standards, or procedures are followed to protect personal and sensitive information?

2. Does your organization use any tools, software, or automated systems for document redaction? If yes, please specify the types of tools used (e.g., AI-based systems, machine learning models, manual redaction tools).

3. Please provide details about any AI or machine learning technologies used to support document redaction, including the names of any software or vendors。If an automated tool or AI-based system is used for document redaction, does your organization include a human review step in the process before finalizing redaction? Please describe the role of human reviewers.

4. Please provide details on training provided to individuals involved in the document redaction process, particularly for AI-based or automated redaction tools. How are staff trained to identify sensitive information and use these tools effectively

5. What are the biggest challenges your organization faces when redacting documents particularly when using automated or AI-based systems?

Disclosure of the requested information to me is in the public interest because it is likely to contribute significantly to the public understanding of the operations or activities of the public authorities; and is not primarily my commercial interest. I hope you will be able to provide this information. If I can assist in any way, please let me know.

Yours faithfully,

Yijun Chen
