Data ownership refers to the rights and responsibilities individuals or organizations have concerning their data in digital contexts. It encompasses issues of who can access, control, and use data, as well as the implications for privacy and security. As data becomes a vital asset, understanding data ownership is essential for compliance with regulations such as the GDPR. Organizations must establish clear policies governing data access and usage, ensuring that stakeholders’ rights are respected and that data is managed responsibly in a way that protects both individuals and institutions.
