Morphology

positive + identification

The meaning 'definitive confirmation of identity' follows directly from 'positive' (certain/definitive) modifying 'identification' (evidence of who someone is). This is a straightforward adjective + noun composition, with only a slightly more formal/technical register, so a B1 learner who knows both constituents would readily infer the MWE's meaning.

Etymology

Positive identification may come from police and court work where an officer looks at a person or a photo and says the match is positive, meaning 'certain', giving a clear identification. That's why the phrase now means a definite, proven match to someone's identity.
