Morphology

liveness = live (semi-transparent) = live + ness

Formally 'live' + '-ness' is clear, but the biometric 'liveness' meaning is a specialized technical sense (detecting spoofs) that may not be obvious to general learners.

Etymology

Liveness here is formed from live ('alive') and -ness ('state'), so it literally means 'being alive'. In security talk, liveness means the checks or signs that show a face or fingerprint comes from a real, living person, not a photo or mask.
