A data subject is an identifiable natural person, in other words, a living individual who can be identified, directly or indirectly, via an identifier such as a name, an ID number, location data, or via factors specific to the person’s physical, physiological, genetic, mental, economic, cultural or social identity. The term "data subject" is used in the General Data Protection Regulation (GDPR) and is important because it is tied very tightly with the term "personal data" in GDPR. Collected data is tied to specific data subjects, and one of the goals of the GDPR is ensuring all personal information of a data subject is treated in accordance with the data subjects consent choice. Ultimately, it is the role of the data controller to ensure the data subjects data is collected and processed correctly.
