I'm aware that comparison of fingerprints is done by extracting/storing/comparing features. But in 2020 the digitization of fingerprints can/should go without saying and the details of how fingerprints are compared are just a distraction at best for most of the general public.
As for 'digital fingerprint' being a good term for that, I disagree. I think that's a term that's very likely to confuse the layperson. If you search that term on wikipedia you'll find a disambiguation page that lists six options, none of which have anything to do with fingers: Message digest, Device fingerprint, Digital video fingerprinting, Acoustic fingerprint, Canvas fingerprinting, Content ID (algorithm)https://en.wikipedia.org/wiki/Digital_fingerprint
If you search the same on google in a private window, the first two or three pages of results are all about the same computer-related topics as that wikipedia page (the first result is that wikipedia page, and the second is a blog post from Mozilla about browser fingerprinting.) After a few pages I started to find pages about digitized prints of fingers, so I don't doubt that people in the fingerprinting industry use this terminology. Nevertheless I can easily see laypeople being mislead.
