The primary use of customer data means that data is used for the purpose for which the data was originally saved for in the customer and/or patient register. Primary use can include, for example, the examination, care or rehabilitation of a patient or the services provided to a customer by social services or the processing of Kela’s social benefits.
The secondary use of customer data refers to the use of the same information in other contexts than in primary use. The secondary uses outlined in the Act include scientific research, compiling of statistics, development and innovation activities, teaching, knowledge management, steering and supervision of authorities, and the planning and reporting duties of authorities.
Different provisions apply to the different uses of data. Only aggregate data from which individuals cannot be identified may be used in the development and innovation activities.
