protected health information medical

"including the scope of any compromise of personal or protected health information"

Protected health information is any personal medical or health-related data that can identify an individual—examples include diagnoses, treatment records, test results, insurance details, or an address when tied to health information. It matters to investors because organizations that collect, store or share this data face strict privacy laws, high breach and liability risk, and potential fines or reputational damage, making PHI a valuable but legally sensitive asset.
