It serves as a detailed map of the data processing activities carried out by a company, providing transparency and accountability in accordance with data protection regulations. This register includes information such as the purpose of data processing, the types of data collected, the legal basis for processing, and any third parties involved. By maintaining a register of processing activities, organizations can ensure that they are handling personal data in a responsible and compliant manner, promoting trust and confidence among their stakeholders.
