Which principle emphasizes the accuracy of personal data under GDPR?

The principle that emphasizes the accuracy of personal data under the General Data Protection Regulation (GDPR) is data quality. This principle asserts that organizations must take the necessary steps to ensure that personal data is accurate, complete, and kept up to date. It stipulates that individuals have the right to have inaccurate personal data concerning them rectified without undue delay. This focus on accuracy is crucial because it helps protect individuals' rights and ensures that any decisions made based on this data are fair and informed.

While other principles like integrity relate to the completeness and security of personal data, and accountability refers to the necessity for organizations to demonstrate compliance with data protection regulations, they do not specifically target accuracy as a standalone requirement. Transparency speaks to how organizations should inform individuals about data collection and processing activities rather than the data itself's accuracy. Data quality, therefore, specifically underscores the need for precise and reliable personal information within the framework of GDPR.
