Practical guides
Prepare an AI task without exposing data
Decide which information is necessary before sharing it. Removing a name does not always make a record anonymous; combinations of details may still identify a person or disclose a confidential situation.

Method
1. Classify the information
Identify personal data, confidential documents and access credentials. Check whether the task is authorised and whether another person’s information is involved. Do not submit secrets to create a more realistic example.
2. Reduce the input
Use a fictional example or only the relevant non-confidential extract. Remove identifiers and unnecessary rare details. Keep the original separately so the prepared copy can be checked.
3. Check the service and output
Read the provider’s actual terms and settings for the intended use. Verify who can access the data and what retention applies. Check that the response does not reproduce details that should not be shared.
Example to adapt
Use a fictional customer record with invented names and rounded values to design a reply template. Do not include account numbers, contact details or any real case narrative.
Checklist
Checks stay on this page; ticking a box does not automatically validate the result.
Deliverable
An authorised, reduced input and an explicit record of excluded information.
Limitations
Pseudonymisation is not a guarantee of anonymity. If confidentiality cannot be assured for the task, use a different workflow rather than relying on a prompt.
