A Personal Data Processing System is any computer system, application, or set of technologies used to collect, store, process, or transmit information relating to identifiable individuals. These systems are designed to handle personal data such as names, contact information, identification numbers, or other attributes that can be linked to a specific person. Personal Data Processing Systems are subject to data protection regulations and must implement security measures to ensure the confidentiality, integrity, and availability of the personal data they manage. Examples include customer relationship management (CRM) platforms, HR databases, and online service portals.
