State bills propose exemption for biometric data converted to irreversible mathematical representations

What happened

Several U.S. state privacy bills are introducing a new exception that excludes biometric data once it is transformed into an irreversible mathematical representation that cannot be used to recreate the original measurement. The proposed language appears in bills such as Mississippi HB 1051 and similar measures in Pennsylvania and Georgia. The exemption could limit the scope of biometric privacy protections for technologies using one‑way mathematical transformations.

Why it matters for trust and compliance

• Its status is proposed. It is not law yet. Track it, but do not treat it as an obligation.
• The trend could reshape biometric privacy safeguards by carving out a carve‑out for transformed biometric data.
• It relates to BIPA. The regulations library explains what that law requires.

Who is affected

Recommended actions

1. Check that privacy notices describe the practices this addresses.
2. Revisit retention schedules and data minimisation for the data involved.
3. Confirm handling of sensitive data categories meets the stricter rules.
