Which of the following fields could potentially be used to identify someone and must be considered closely when publicly releasing the data? (Select all that apply)

Question

Movie preferences

Friends

Zip codes and birthdates

Ice cream preferences

Neighbors

None of the above

Answer 1

The fields that could potentially be used to identify someone and must be considered closely when publicly releasing the data are:

• Zip codes and birthdates: This combination can lead to identification, as they provide specific demographic information that can narrow down an individual's identity.

• Neighbors: This information can also contribute to identifying someone, especially in smaller communities where neighbor relationships may be well-known.

The other fields like movie preferences, friends, and ice cream preferences are less likely to be used for identifying an individual unless combined with other identifying information. "None of the above" is not correct since zip codes and birthdates as well as neighbors are significant in this context.
