Data Pseudonymization

Meaning

A highly technical data protection measure where personally identifiable information (PII) is replaced with a reversible, artificial identifier or pseudonym, allowing the physiological data to be processed and analyzed without directly revealing the individual’s identity. Unlike irreversible anonymization, pseudonymization maintains a secure key or mapping that permits re-identification only when absolutely necessary and under strict control, which is vital for longitudinal clinical research and personalized health tracking. This technique is a crucial tool for balancing the need for data utility in scientific advancement with the fundamental right to privacy.
