Data sovereignty is the ability of a legal person or an organisation to control the conditions that data is shared under, and how that shared data is used, as if it were an economic asset.[1][2] It can apply to both primary data and secondary data derived from data, or metadata.[3] In order to use restricted data, data consumers must accept the conditions that it is provided under.[4] In turn, the legal persons sharing data must trust other entities with it. Trust can be supported through the use of a suitable secure information system (such as a data space) which identifies, authenticates, and certifies users.[5]
