 Pseudonymization

Pseudonymization is a data management and de-identification procedure by which personally identifiable information fields within a data record are replaced by one or more artificial identifiers, or pseudonyms.A single pseudonym for each replaced field or collection of replaced fields makes the data record less identifiable while remaining suitable for data analysis and data processing

Pseudonymization (or pseudonymisation) can be one way to comply with the European Union's new General Data Protection Regulation demands for secure data storage of personal information.
