What it means
Privacy and security overlap
Security controls can help protect information, but a secure system can still expose unnecessary personal details through its intended design. Data collection, sharing and retention must be evaluated for the actual purpose and applicable framework.
Payment information can be revealing
Account references, customer records and transaction activity can become sensitive when linked together. Public blockchain visibility and pseudonymous addresses do not establish anonymity. Keep payment references and private customer or clinical information appropriately separated, and understand which service receives each field.

In practice
A concrete example
A business uses a non-descriptive payment reference while keeping the customer’s private details in its access-controlled business records.
Technical notes & boundaries
Privacy obligations differ by jurisdiction and data type. HIPAA is one specific US framework, not a global privacy standard or a general certification for payment software.
