Why is this change being made?
The purpose of this PR is to sanitize text input from potentially confidential dates, such as dates of births.
Dates of birth are considered sensitive PII and are often used for identity verification. Scrubbing them ensures compliance with privacy regulations.
What is changing?
An additional function
scrub_dates()has been added, which matches text found in the input against typical date formats. The function replaces dates matching regex patterns with "[REDACTED DATE]".How did I test?
Test cases have been added to
tests/test_pii_scrubber.pywhich test the pii scrubber against various date formats, including ISO, USA, EUR and variations of each. This includes cases where months and days are single-digit.Assuming correct env setup, tests can be run using:
poetry run pytest tests/test_pii_scrubber.py::test_scrub_dates
