What do both the Data Protection Act 1998 and GDPR 2018 primarily protect?

The correct choice focuses on the primary objective of both the Data Protection Act 1998 and the General Data Protection Regulation (GDPR) 2018, which is to safeguard individuals' personal data, particularly sensitive personal data. This includes information that is private, such as health records, biometric data, and other details that could identify an individual.

Both pieces of legislation impose strict rules on how personal data must be stored, processed, and shared, ensuring that people have control over their own information. This is crucial in fields such as healthcare, where confidentiality is paramount to maintaining trust between patients and providers.

In contrast, the other options address more specific areas that do not encompass the broader aim of data protection laws. Protecting the rights of dental practitioners, financial information of the practice, and the licensing of healthcare providers are important but do not align with the main goal of these regulations, which prioritize the protection and privacy of individuals' personal information.
