Anonymisation and pseudonymisation

Ethics & compliance

Anonymisation makes it impossible to re-identify a person, so the data is no longer subject to the GDPR. Pseudonymisation replaces names and identifiers with aliases, with a matching key stored separately, so the data remains personal and the GDPR still applies. Both techniques reduce risk before data is sent to an AI model.

In practice at Gensai

Pseudonymising personal data is one of the measures Gensai considers when client documents have to be processed by a hosted model.
