Personal data under GDPR: Defining and protecting individual information
Personal data is any information that relates to an identified or identifiable living person. Under the General Data Protection Regulation (GDPR), personal data is strictly regulated to ensure that individuals’ privacy rights are protected when their information is processed, stored, or shared.
GDPR applies to all controllers and processors handling the personal data of data subjects in or from the European Economic Area (EEA), regardless of where the organization is located.
What qualifies as personal data under GDPR?
A person is identifiable if their identity can be determined directly or indirectly through one or more unique identifiers.
Examples of personal information
- Direct identifiers – Name, email address, phone number, home address.
- Online identifiers – IP address, cookies, device IDs, geolocation data.
- Financial data – Bank account numbers, credit card details.
- Sensitive personal data (special category data) – Health records, biometric data, racial or ethnic origin, political opinions.
- Behavioral data – Purchase history, browsing habits, social media interactions.
What is NOT considered personal?
- Anonymized data – If a dataset is processed in a way that individuals can no longer be identified, it falls outside GDPR’s scope.
- Company registration numbers – Business information that doesn’t relate to an individual.
- Aggregated data – Statistical data that does not allow individual identification.
