Personally Identifiable Information
Data that can identify a specific person, such as a name, address, or ID number.
Definition
Personally identifiable information is any data that can identify a specific person, such as a name, email address, phone number, or government ID. In AI pipelines it is a privacy concern because it can leak into training data and resurface in model outputs. Curation steps often detect and remove or mask it, using methods like pseudonymization and de-identification to reduce risk.
