Data de-identification is best described as which of the following?

• A. Removing identifiers from data to protect privacy when shared
• B. Encrypting data
• C. RACI chart
• D. Health information exchange

Answer: (A)

Data de-identification is the process of removing or masking personal identifiers from a dataset so it can be shared or analyzed without revealing who the individuals are. By stripping out names, exact addresses, telephone numbers, exact dates, geographic detail smaller than a state, and other unique IDs, the data becomes much harder to link back to a person while still allowing useful analysis. This approach supports privacy protections and regulatory compliance (such as HIPAA) when data are used for research, quality improvement, or benchmarking. Encryption, while it protects data from unauthorized access, does not inherently remove identifiers and can still allow re-identification if the data are decrypted. A RACI chart is about assigning roles and responsibilities, not about data content or privacy. Health information exchange focuses on moving and integrating data between systems; de-identification is a privacy step that often precedes or accompanies such sharing to reduce re-identification risk.
