How can health information privacy be protected in the age of digital health?

• A. Publicly sharing patient data to improve transparency.
• B. Data minimization, consent, access controls, encryption, audit trails, and governance policies.
• C. Storing data only on local devices without backup.
• D. Ignoring user permissions to simplify data access.

Answer: (B)

In digital health, protecting health information privacy relies on a multi-layered approach that combines data minimization, informed consent, access controls, encryption, audit trails, and governance policies. Data minimization means collecting only what’s truly needed and keeping data only as long as necessary, reducing exposure if a breach occurs. Informed consent ensures patients understand and agree to how their data will be used and allows them to revoke or modify permission. Access controls and the principle of least privilege keep data viewable only by those who need it for legitimate tasks, limiting internal exposure. Encryption protects data both at rest and in transit, so even if data is intercepted or accessed without authorization, it remains unreadable. Audit trails provide a detailed record of who accessed what data and when, supporting accountability and the ability to detect unusual or unauthorized activity. Governance policies establish clear rules, roles, data stewardship, privacy impact assessments, and incident response, aligning day-to-day practices with legal and ethical standards. Together, these elements create a comprehensive privacy framework that addresses technical protections, user rights, and organizational accountability. Publicly sharing patient data, lacking proper consent, or bypassing permissions would undermine confidentiality and trust; likewise, storing data only on local devices without backup increases risk of loss and bypasses essential safeguards.
