Personal Data

Personal Data

• A. Any piece of data used to identify a person
• B. A password
• C. An encryption key
• D. A device serial number

Answer: (A)

Personal data is information that can be used to identify a person. It covers direct identifiers like names or contact details, and even data that could identify someone when looked at in context or with other data, such as location data or an ID number. The other options aren’t about people themselves: a password is a secret used to prove who you are, not information about the person; an encryption key is a cryptographic tool; a device serial number identifies a device, not an individual. So the description that best fits personal data is any data that can identify a person.
