MCDPA classifies data revealing racial or ethnic origin, religious beliefs, mental or physical health condition or diagnosis, sex life, sexual orientation, citizenship or immigration status, the processing of genetic or biometric data to uniquely identify an individual, a known child's data, and precise geolocation data as sensitive data.
'Biometric data' means data from automatic measurement of biological characteristics used to identify a person, such as a fingerprint or voiceprint, and the raw recording is excluded, but data generated from it is covered once generated to identify a specific individual, matching the Connecticut, Oregon, Delaware, and Nebraska structure.
