It is tempting. Handing an employment contract to an AI to check a tricky clause, rewrite an amendment or compare two versions saves any stretched HR team a serious amount of time. The snag? A contract is packed with very personal data: the employee's name, salary, address, sometimes the national ID. Paste it into ChatGPT and you hand it to a third party. The fix takes three simple, reversible steps: pseudonymize the document before the AI, keep the key, re-identify afterwards.
The employee and address are masked ; the role and salary stay, useful to check or explain a clause.
What to mask in an employment contract
- The employee's name and contacts.
- The salary and pay détails.
- The address, date of birth and national ID.
- Internal références (staff number, file number).
The method, without changing your tools
Nothing to reinstall. You pseudonymize the contract, then work with your usual AI on the masked version, where the employee becomes PERSONNE_1 and the salary becomes SALAIRE_1, exactly as you always would. And then? You re-identify the result locally, in one click. The AI has checked the clause without ever knowing who it is about.
Safe-Doc handles it. It pseudonymizes every contract before the AI, preserves the original layout in PDF and Word alike, processes the data inside the European Union, then purges it the moment the job is done. That is the whole point. More on the Safe-Doc for HR page.
Test it on a real contract. Pseudonymization is reversible. Layout preserved, down to the comma.
