Which regulation enforces rules for organizations serving the European Union concerning data collection?

The General Data Protection Regulation (GDPR) is the regulation that enforces rules for organizations operating within the European Union regarding the collection, storage, and processing of personal data. Its primary aim is to protect individuals' privacy and provide them with greater control over their personal information. GDPR applies not only to organizations located within the EU but also to those outside the EU that offer goods or services to, or monitor the behavior of, individuals residing in the EU.

Key principles of the GDPR include data minimization, transparency, accountability, and the rights of individuals concerning their data, such as the right to access, rectification, erasure, and data portability. Organizations must ensure compliance with these principles and can face significant fines for violations, underscoring its importance in the realm of data protection.
