Pseudonymise a customer file

Situation

The situation

Give the AI the need, not the identity.

You work at a communications agency in Marseille. You want the AI to sort your customers by type of need to prepare a campaign. Your list contains names, emails and phone numbers.

Idea 1 of 3

Pseudonymising means replacing

To pseudonymise is to replace what identifies a person with a marker: [CUSTOMER 1], [CUSTOMER 2]. You keep the list matching each marker to its customer, and you put the real names back at the end.

Idea 2 of 3

The aidock Shield

Before sending, the Shield replaces emails, phone numbers, IBANs, IP addresses, and card, social security, SIREN, SIRET and VAT numbers with markers such as [EMAIL 1], in your browser. The answer is shown with your real values, which never leave your device.

Idea 3 of 3

Its limits

The Shield also masks the names you add to its list. Names and health data are not detected automatically. This is pseudonymisation: the rest of the text may still identify someone.
