1. Overview of Data Protection Obligations under UK GDPR

Ensure transparency, accountability, and fairness in processing.

Prevent unauthorized access, loss, or misuse of personal data.

Enable enforcement and redress through regulatory oversight.

2. Core Data Protection Obligations

Data subjects must be informed about how their data will be used.

B. Purpose Limitation

Personal data must be collected for specified, explicit, and legitimate purposes and not further processed in ways incompatible with those purposes.

C. Data Minimization

Only process necessary data relative to the purpose.

D. Accuracy

Organizations must ensure accuracy of personal data and correct inaccuracies promptly.

E. Storage Limitation
