The use of machine learning in Human Resources (HR) and payroll systems represents significant capability gains for automation, decision-making, and operational efficiencies. However, this transition process raises significant concerns related to the protection of sensitive employee data. Privacy-preserving computer scientific methods, like de-identification (removing or altering identifiers such that the individual cannot be identified), are becoming an increasingly important way to preserve privacy while maintaining the richness of datasets for use in analytical research.
The purpose of this review article is to provide a comprehensive report on various privacy-preserving techniques, especially de-identification techniques common to HR and payroll data. The review will include real-world examples of privacy-preserving methods, including CV de-identification, clustering of quasi-identifiers (QI), narrative-level de-identification, and federated learning (model training without the data leaving the local source, but sharing model updates). The article looks at implications for privacy and utility trade-offs, assesses potential reidentification risks, and summarizes innovations in secured data, such as format-preserving transformations (anonymizing and preserving values such as IDs/dates) and voice anonymization. The review article considers issues identified in the current literature, as well as policy implications and future directions for utilizing secure and compliant machine learning frameworks in human resource settings.
