Personally Identifiable Information (PII)
The NB Defense scans for any information that can be used to identify a person i.e., personally identifiable information (PII). It can be their name, location, bank information etc.
NB Defense supports both global entities (such as names, email addresses) as well as country-specific entities (such as UK National Health Service (NHS) number). At the moment, the NB Defense PII plugin has support for English language only.
The PII analyser is adapted from Miscrosoft Presidio whereas the PII anonymization is handled by NB Defense.
Warning
Before you begin scanning with the PII plugin, please execute all code inside the notebook you would like scanned. This plugin does not execute code, and will only scan output for PII if it exists in the notebook.
