A data analyst is working on a dataset that contains customer information. For a marketing analytics project, the dataset needs to be shared with a third-party vendor. According to data privacy guidelines, all Personally Identifiable Information (PII) must be masked or removed before the data is shared. Which of the following data fields should the analyst prioritize for removal as it is a direct form of PII?
The correct answer is Customer Email Address. Personally Identifiable Information (PII) is any data that can be used to distinguish or trace an individual's identity. A customer's email address is considered a direct identifier because it can be used to directly identify and contact a specific person.
Postal Code is considered quasi-identifying or linkable information. By itself, it typically refers to a large geographic area and many people, but it can become identifying when combined with other data elements.
First Purchase Date is transactional data and does not directly identify a specific individual on its own.
An Anonymized Customer ID has undergone a process specifically to remove its connection to an individual's identity, and therefore is not considered PII.
