Which is a key privacy and data security practice for digital health data?

• A. Collect all possible data without consent to maximize usefulness
• B. Anonymous data sharing on public forums
• C. Data minimization, encryption, access controls, informed consent, and regulatory compliance
• D. Keeping data unencrypted on personal devices

Answer: (C)

The main idea is that protecting digital health data relies on a comprehensive set of privacy and security controls. Data minimization means only collecting what is truly necessary, which lowers exposure if a breach occurs. Encryption protects information by making it unreadable to unauthorized people both when it’s stored and when it’s being transmitted. Access controls ensure that only people with legitimate roles can view or modify the data, and they’re typically supported by authentication and audit logging. Informed consent respects patient autonomy, making sure individuals understand what data is collected and how it will be used. Regulatory compliance, guided by laws and standards, sets baseline requirements for safeguarding data, handling breaches, and supporting patient rights.

Together, these practices create a responsible, defensible approach to handling digital health data that addresses privacy, security, and legal obligations, which is why this option is the best fit.

By contrast, collecting all possible data without consent overshoots privacy rights and violates trust; anonymous sharing on public forums isn’t reliably private and can often be de-anonymized; keeping data unencrypted on personal devices leaves data exposed to loss or theft.
