Tredjepartsdata

Tredjepartsdata, or third-party data, refers to information that is collected by an entity that does not have a direct relationship with the data subject and is then provided or sold to another organization. This contrasts with first-party data, gathered by the organization itself, and second-party data, shared directly by a partner.

Common data types include demographic details, interests, online behavior, device identifiers, location history, and purchase data. Collection occurs through cookies and tracking technologies, app analytics, data brokers, publishers, affiliate networks, and public records. Data may be aggregated, anonymized, or pseudonymized, depending on the source and use.

Organizations use tredjepartsdata to enhance customer profiles, support targeted advertising, perform segmentation, enrich analytics, and improve risk assessment or fraud detection. It is often integrated with internal data to broaden insights when first-party data are limited.

Privacy and regulatory concerns are central. Compliance requires lawful basis for processing, clear disclosure, consent where required, purpose limitation, and robust data processing agreements. Cross-border transfers may be subject to restrictions. Anonymization and data minimization reduce risk, while strong security measures protect data in transit and at rest.

Quality and provenance can vary widely, affecting accuracy and trust. Users may object to opaque data practices, and regulators increasingly scrutinize third-party data ecosystems. Responsible usage emphasizes transparency, governance, and ongoing evaluation of data sources.
