Pseudonymisation

In Good Clinical Practice & ethics

Also known as: coding, de-identification

Pseudonymisation replaces a participant's directly identifying details with a code, so that data can be analyzed without naming the person. The link between the code and the identity still exists but is kept separately and securely. It reduces privacy risk but does not make data fully anonymous, because re-identification is still possible with the key.
