What refers to the responsibility assigned to a data owner based on specific dataset characteristics?

The correct choice highlights the concept of data classification, which involves categorizing data based on specific characteristics such as its sensitivity, importance, or regulatory requirements. This classification process helps data owners to determine how the data should be managed, protected, and accessed. Different datasets may have varying security needs and compliance requirements; thus, understanding their specific characteristics allows the data owner to implement appropriate controls and policies.

Data classification ensures that sensitive information is identified and safeguarded according to its level of criticality and compliance obligations, such as those outlined in laws like GDPR or HIPAA. This process serves as a foundational element of data governance and stewardship but specifically refers to the systematic organization and management of data according to predefined criteria.
