A data controller is a person or organization that determines the use of personal information. The role of the data controller can be shared by many people or organizations.
Rights and responsibilities of data controllers include:
establishing a lawful data process and observing the rights of Data subjects (including collecting data subject Consents and requests)
issuing instructions on data processing (including appointing employees to serve as point of contact) for the Data processor – the data processor should handle data exclusively in the manner prescribed by the controller.
