Processing activity: Defining and documenting data handling under GDPR

A processing activity refers to a specific operation involving personal data, such as collection, storage, transfer, or deletion. Under Article 30 of the General Data Protection Regulation (GDPR), organizations must document their processing activities in a Record of Processing Activities (ROPA) to ensure compliance and accountability.

Each processing activity must clearly describe why and how personal data is handled, including details about data subjects, data categories, processing purposes, and security measures.

What information must be documented for a processing activity?

A processing activity record must include:

  • The name and contact details of the controller or processor.
  • The purpose of processing (e.g., customer management, payroll processing).
  • Categories of data subjects (e.g., customers, employees, suppliers).
  • Types of personal data processed (e.g., names, emails, financial details).
  • Recipients of personal data (e.g., third-party service providers, regulators).
  • International data transfers (if data is sent outside the EEA).
  • Retention periods (how long data is stored).
  • Security measures implemented to protect the data.

Maintaining accurate and up-to-date documentation ensures that organizations comply with GDPR and can demonstrate accountability when required.
