# Data pseudonymization

*Last updated: 2026-06-26*

> Pseudonymization protects sensitive information without disrupting operational processes: identifying attributes are replaced with neutral codes or tokens—a customer ID instead of a name, or a UUID in place of driver details on a shipping label.

Pseudonymization protects sensitive information without disrupting operational processes: identifying attributes are replaced with neutral codes or tokens—a customer ID instead of a name, or a UUID in place of driver details on a shipping label. Re-identification remains possible as long as the mapping table exists, which must be stored separately and secured. Under GDPR, pseudonymized data still qualifies as personal data, but the technique supports a more privacy-friendly processing approach: if a breach occurs, the exposed records are far less useful without the separate key file. The critical distinction from anonymization is reversibility—deliberately retained in logistics contexts where systems need to link back to the individual during an active shipment but should drop that link once the transport is complete.
